Did u replace all the brake lines, front and back brakes replaced? Make sure u did the following:
1. make sure master cylinder is topped off (full)
2. go to the bleeder the greatest distance from the master cylinder, Have someone pump the brake pedal 3 times, each time about half way down w/ pedal, on 3rd pump, they should depress the pedal half way and hold it there while u open the bleeder. When air or fluid comes out and it begins to slow, gently snug the bleeder valve shut before the pedal is released. Continue to do this until only clear, clean fluid is flowing. Keep checking the master cyl. level, if u let it go down too much u will **** air into the line and have to start all over. Go to the next bleeder that is farthest away, etc. til u do the closest bleeder. Car should be running doing this, and you MUST use safety stands so u don't have the car falling on u while u work under it. Also make sure all your new brake line connections are tight, or it will allow air into the lines. Let me know how this works for u. good luck countrycurt0

Did you 'bench vise' bleed the master cylinder? Also, the proper way to bleed the brakes is to start with the one closest to the master cylinder and work your way to the one furthest away. Did you re-hook up all vacume lines?

i would have to say the master brake cylinder is at fault. there are ports in the cylinder that allow fluid back into the reservoir. these ports may be clogged. or the brake hose/line is clogged. have you changed the brake hose?

you may have air trapped in the ABS EHCU. Did you use this procedure?

Bleeding the EHCU

Bleeding the EHCU requires the use of the TECH-1 scanner or its equivalent and the appropriate cartridge. Additionally, 3 tools, J-39177 or equivalent, are required. Bleeding cannot be performed without this equipment.
The EHCU must be bled after replacement or if air is trapped within the unit. It must be bled after bleeding the master cylinder and before bleeding the individual wheel circuits.
The Internal Bleed Valves on either side of the unit must be opened 1 / 4 - 1 / 2 turn before bleeding begins. These valves open internal passages within the unit. Actual bleeding is performed at the two bleeders on the front of the EHCU module. The bleeders must not be opened when the system is not pressurized. The ignition switch must be OFF or false trouble codes may be set.

  1. Open the internal bleed valve 1 / 4 - 1 / 2 turn each.
  2. Install one tool J-39177 on the left bleed stem of the EHCU. Install one tool on the right bleed stem and install the third tool on the combination valve.
  3. Inspect the fluid level in the master cylinder, filling if needed.
  4. Slowly depress the brake pedal and hold it down.
  5. Open the left bleeder on the front of the unit. Allow fluid to flow until no air is seen or until the brake pedal bottoms.
  6. Close the left bleeder, then slowly release the pedal. Wait 15 seconds.
  7. Repeat Steps 4, 5 and 6, including the 15 second wait, until no air is seen in the fluid.
  8. Tighten the left internal bleed valve to 5 ft. lbs. (7 Nm).
  9. Repeat Steps 3-7 at the right bleeder on the front of the unit.
  10. When bleeding of the right port is complete, tighten the right internal bleed valve to 5 ft. lbs. (7 Nm).
  11. Remove the 3 special tools.
  12. Check the master cylinder fluid level, refilling as necessary.
  13. Bleed the individual brake circuits at each wheel.
  14. Switch the ignition ON . Use the hand scanner to perform 3 function tests on the system.
  15. Carefully test drive the vehicle at moderate speeds; check for proper pedal feel and brake operation. If any problem is noted in feel or function, repeat the entire bleeding procedure.

How do i disable r/r caliper on 2004 expedition


The only way to disable a rear brake caliper that is seized is to get a small pry bar and use force to slide it back to the release position.place the pry bar in. The open space top of the caliper
25451082-az15v3devurpko3w4b520lul-5-0.jpg Then if I were in this situation since you come this far I would simply replace the caliper the slide bolts are 7mm Allen type.
then remove the brake fluid feed line don't forget to replace the
copper seals on the main brake fluid feed connector.
then bleed the system do this by opening the air bleed
valve its 8 or 10 mm just crack it open maybe you one full
turn then place your finger on the top were the fluid comes out.
have some one pump brakes slowly all the way down and release
brake pedal continue this until you feel pressure at tip of your
finger then release brake pedal on the last pump hold brake pedal
down and tighten then release pedal.
Good to you!

Did not return the fluid from caliper


Ok. I am not sure what you are meaning by "did not return fluid from caliper" but if you are trying to bleed out the caliper,make sure you have enough fluid in the brake fluid resevoir under the hood.And then have someone pump the brakes 5 or 6 times,then hold the pedal down.With the pedal held down,loosen the bleeder screw on the caliper.The brake pedal should go down to the floor.Tighten the screw then let the brake pedal up. Do this until you have a steady squirt of brake fluid come out of the bleeder screw when you push the brake pedal down and loosen the screw.If you keep doing it and no fluid is coming out,then you either have too much air still in the line,not enough fluid in the system, or you have a blockage in the line.Make sure you bleed the brakes at all 4 wheels.Good luck

I have a 2004 Land cruiser and changed the right rear brake cyl and brake shoes . What is the proper procedure to bleed the rear brake system. Thank you for your help.


  1. Check the fluid level in the reservoir after bleeding each wheel. Add DOT3 fluid, if necessary.
  2. If the master cylinder was disassembled or if the reservoir becomes empty, bleed the air from the master cylinder as follows:
    1. Disconnect the brake lines from the master cylinder.
    2. Slowly depress the brake pedal and hold it.
    3. Block off the outlet plug with your finger, and release the brake pedal.
    4. Repeat 3 or 4 times.

  3. Bleed the brake starting with the one furthest from the reservoir and then the next furthest, etc.
  4. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
  5. At the point when fluid stops coming out, tighten the bleeder plug to 11 Nm (8 ft. lbs.), then release the brake pedal.
  6. Repeat until all the air in the fluid has been bled out.
  7. Repeat the procedure to bleed the air out of brake line for each wheel.
  8. Check the fluid level and add DOT3 fluid if necessary.

What are the proper steps to bleeding your brakes on a 1990 vw golf deisel


For left hand drive vehicles: (If the car does not have ABS system you do not need any diagnostic equipment!)

IMPORTANT NOTE: You need using diagnostic equipment connected to the data link connector of the car in order to bleed the ABS block. Follow instructions by scantool equipment for bleeding the ABS block.


1. This bleeding procedure requires two people. Remove the brake system reservoir cap, and fill up with new brake fluid until "MAX" level is reached.
2. Lift the car, or use a channel for access under vehicle.
3. Put the gearbox in "N" - Neutral position, or in "P" - Parking position for automatic transmission.
4. Start the engine and push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor.
5. Begin with the rear right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
6. Repeat steps no.#4 and no.#5 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

7. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
8. Continue with the rear left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
9. Repeat steps no.#7 and no.#8 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

10. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
11. Continue with the front right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
12. Repeat steps no.#10 and no.#11 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

13. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
14. Continue with the front left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
15. Repeat steps no.#13 and no.#14 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.
16. Now the brakes are bleeded. Check the brake fluid level in the reservoir. Fill up with new brake fluid until "MAX" level is reached. Put back the brake reservoir cap.
17. Test the car brake system. The brake pedal movement no more than 1/3 of total stroke until the floor, when brake pedal is applied. Maximum admissible is 1/2 of total stroke.

How to replace front calipers on 04 dodge ram 1500


Support the vehicle on Jack Stand. Remove the Tire. Loosen the two retaining bolts on the back of the Caliper, 1 on each end, Disconnect the brake line. Install the new caliper and from there you have two options. 1. Let the Caliper hang free and open the bleed valve on the Caliper with the engine running, when you see fluid start to drip from the Bleed valve close the valve then complete the installation. (Make sure you remove the rubber cap from the bleed valve) 2. (This takes two people) Install the pads in the Caliper then install the Caliper. Make sure the brake fluid is topped off. Start the vehicle and pump the brakes 3 to 4 times then hold the brake pedal down. The person on the outside releases the Bleed valve, in this process the brake pedal will go to the floor, Once the Pedal is all the way down close the valve and repeat the process checking to make sure the Fluid is topped off after each attempt. Repeat the process until only fluid comes out when you open the bleed valve. This usually takes 2 to 3 cycles. Once the air is removed from the caliper and brake line top off the fluid one last time and install the tire.

Brakes only working on driver side, rear and front, no brakes on passenger side rear and front. fluid good, lines good.


There only a few things that would cause this that you need to check, first start at the front wheel that doesnt work, have someone applie the brake open the bleeder screw if fluid sprays then caliper is bad or caliper slides are frozen, if no fluid comes out then you have a bad brake hose at that wheel, do the same to rear if fluid comes out of bleeder in rear then wheel cylinders are no good if no fluid comes out then brake hose to rear wheels is no good, make sure to have pedal pressed and repush pedal when checking the rear. hope this helps.

How do I bleed the front brakes on a 2004 audi a4 quattro?


For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow: 1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose! 2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper. 3. Now you must thoroughly clean the brake calipers (free of grease). 4. Remove outer brake pad from brake carrier. 5. Pull inner brake pad out of brake caliper piston. 6. Check up the brake fluid level on the reservor, and emptying if neccessary! 7. Push piston back into brake caliper housing. 8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward). 9. Install outer brake pad into brake carrier. 10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 11. Install both caps. 12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!!

Replacing brakes


hiya bonnie if you intend to DIY the brakes ? front pads? or rear shoes ? the front pads are easy enough for you to change in fact the pads/and calipers are virtually the same as ford and peugeot they are sliding type calipers that are held in position by 2x bolts that screw into the pins from rear of caliper when bolts removed the caliper pulls off reassembly is reverse after you push piston back the pads fit into the caliper carrier then refit/secure the caliper and pump brake pedal to take up the pads to discs B4 you move car then!bleed each brake a couple of pumps till fluid is clean the fluid that comes out first will be dirty due to heat absorbsion resulting in spongy pedal you will find pedal is more positive/hard when you bleedbrakes as i suggested brake fluid does absorb heat and moisture over time that is why it is recommended you bleed fluid to clear old fluid in lines nearest the cylinders hope this helps ? if you req further help come back will be glad to help best wishes from rochdale
