    i have a lot of problems with the emergency brake as well. Also the rear brakes want to grab and cause me to skid. I have replaced the cylinders, turned the hubbs, and replaced the rubber hoses. The problem returns in a few thousand miles everytime...

There is an adjustment under the van near the frame driver side near the gas filler tube.. use a wrench to tighten the cables...also check and see if your shoes are worn out. the farther they wear, the less your emergency brake will hold. Finally if none of this works, you may have stretched cables and have to replace them....

Brake pedal goes to floor after fixing leak in line and bleeding brakes


neither is bad. The proportioning valve is kicked and they can sometimes be a bear to re center. Here's the best way I've had success doing that. Before you try opening up any more bleeder screws you, 1)top off the brake fluid reservoir, 2) slowly pump the brake pedal, not all the way to the floor and without the engine running but with the key on, about 20 to 30 times. After you do that you very quickly hit the brake pedal very hard but not all the way to the floor. The repeated slow pumping of the pedal will very slowly put pressure into the line, even if it's air it will compress a little at a time and when you jab the pedal that one time at the end it will re-center the valve. Now here's the key. If the brake light is on it should shut off when that valve centers itself. That's when you must bleed the air out but whoever you have helping you tell them not to push the pedal all the way to the floor again or the valve will pop again. Open the bleeder to the caliper that had the blown line and then have them push slowly down on the pedal only half way to the floor and then stop pushing and hold position til you tighten the bleed screw. After you close the bleeder screw they can let up and do it again. If he pushes it to the floor and you hear a click that means the valve kicked again and you need to start over. Time consuming, yes but it works. I hope this makes sense. Sometimes it's hard to relay what I do to words on paper,.

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.

I had to unhook the brake line on the right front tire (1998 4runner)to remove the starter, wondering what I need to do to bleed the brakes now.


To bleed the brakes you need someone to pump the brakes and someone to watch the air valve on the back of the brakes until the air is out of the line. Once the air valve on the back of the brake line starts to flow brake fluid clearly then the air will be out. Recap the air valve and you should be ok.

How to bleed the brakes after you replace rear brake lines


hi, if you look at the back of the brake drum you will see a little bleed nipple just sticking out think its an 8ml or 10ml spanner fit, what you then need to do is find a piece of plastic pipe that will fit over the top of this to catch any fluid then make sure the brake fluid is topped up, you then need someone in the car to operate the brake pedal and some one at the back where the bleed nipple is once you have this you need to do the following

1 undo bleed nipple a couple of turns
2 get person in the car to push brake pedal to the floor and hold it on the floor.
3 when pedal is at floor tighten the bleed nipple up and get the person to let the brake pedal come up.
4 when pedal is up all the way undo bleed nipple and get person in car to push pedal to floor.
5 when pedal at floor tighten bleed nipple up
6 let pedal up
7bleed nipple undo a bit
7 pedal down to floor
8bleed nipple do up
9 pedal up
10undo bleed nipple

now keep doing that until all you have got coming out is fluid and no air when you have this do bleed nipple up and check the brakes to make sure they are not spongy.

whilst doing this you need to make sure the brake fluid level dont drop to low as you will have to bleed the front as well so keep checking the level and make sure its well topped up throughout the whole process

if you have any problems give me a shour back ok

Have brakes with vehicle off, when car is started brake pedal goes to floor


Very careful here you have no Fluid or very very low fluid possible Broken brake line busted
look carefullly at where it sits Check the ground Observe the fluid resorvoir for fluid IF its very low below the chambers walls in the resorvoir you may have to add then bleed off the air in the lines that got sucked in BUT first Try your emergency brake... use it and be ready to pull it up after car starts and goes into gear . Be ready to yank that Emergency up to stop vehicle if pedal does not have enough pressure in line to stop the car.. if its low add if its empty be prepared to see a puddlew of clear brake fluid on ground under vehicle 91 likely broken line they rust out...had a 92 line brake just pressing the pedal in driveway ...at full speed you will coast for blocks until you figure out to use Emergency brakes or Turn off key steer to open spaces my friend ... nothing to trifle with innocent folks walking have no idea you can not stop

How do I bleed air from the brakes


Two persons are required: one to bleed and other to press brake pedal.
Remove wheel and hub of the side you want to bleed. You will find the bleed nut there. Open it a little until some oil flows out. Ask the other person to press brake pedal with steady pushing and withdrawing until he feels its tight while you slowly tighten the nut. Adjust tightness of pedal by trial. Don't forge to refill the brake fluid after bleeding all the brakes.

Do give my solution the highest rating if it solves your problem. Thank you for using fixya!

EMERGENCY BRAKE PEDAL GOES DOWN TO THE FLOOR WHEN ENGAGED


sounds like you have a worn set of park break shoes. they are located inside /behind the read rotors. if you remove the rotor and the shoes look fine then you can adjust them with the little star gear located on the bottom of the brake shoes.
