Loosen the front brake line that goes to the master cylinder fill master cylinder up with fluid and bleed it first by attaching a flexible line from master cylinder front brake side submerge that line into jar of brakefluid keeping air from entering line get someone to pump brake pedal while ur holding line in a jar keep refilling the brake resivoir so no air gets in, once the master is bled front brake side then reattach the origional brake line then remove bleed screw from caliper and let fluid gravity flow down to calliper then bleed the normal way. more than likely your master cylinder has air trapped in the front portion good luck

Need to rest my proportional brake valve on my 1996 sonoma 4x4 I replaced all the brake lines to the ABS, the ABS brake light stays on and I have only less than half the brake fluid flow at the rear


By the sounds of it you need to bleed your brakes the ABS light should go out by itself if this is done unless their is a ABS problem.Remeber when you bleed brakes that have ABS you must have the vehicle running when you bleed them.

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.

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.

Driver side brake not bleeding properly after bleeding left side and changing rotors, calipers, and pads?


first of all make sure master cylinder is full of brake fluid.then you crank car leave foot off brake pedal. watch abs light on dash it should turn off in 10 seconds if not have car towed to garage or dealer. they have to use a scanner to scan the abs brakes if abs light turn off in 3 seconds. then starting bleeding from master bleed the lower brake line fitting at the proportional valve followed by the upper brake line fitting. keep eye on brake fluid in mastercylinder dont let run dry.next prime the abs hydralic modulator.connect the bleeder hose to the rear bleeder valve on the modulator.place the other end into a container partially filled with cleab brake fluid.make sure the end of the hose is submerged.open the bleeder valve slowly about 1/2 to 3/4 turn have an assistant depress the brake pedal and hold it in the depressed position. when the flow of fluid ceases close the bleeder valve.repeat process until no air bubbles are present in the fluid.then tighten the bleed valve securely. start bleeding brakes. your bleeding sequence is right rear - left front - left rear - right front.WARNING IF ALL FAILS YOUR BRAKES DONT FEEL SOLID AND FEEL VERY SPONGY.DONT DRIVE CAR. HAVE IT TOWED TO DEALERSHIP.THEY WILL HAVE TO PRESSURE BLEED YOUR BRAKE SYSTEM.

1994 Cavalier -replaced master cylinder-no pressure to rear brake


The most common bleeding procedure is to bleed the ABS brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.
Air can be very difficult to remove from an ABS modulator assembly because of all the nooks and crannies inside the unit. The modulator may have eight to 10, or more, ABS/traction control solenoid valves, plus various check valves and dead-end ports. Some ABS modulators have special bleed screws to help you vent the trapped air when bleeding the system. Others do not and require the use of a scan tool to cycle the ABS solenoids while you bleed the system. 1. To bleed the isolation valves in the modulator, there are two bleeder screws. Start with the one toward the engine. Turn the ignition on and apply light pressure on the brake pedal. Open the bleeder screw and allow the fluid to flow until clear. Close the screw and do the same at the second bleeder screw. 2. Depressurize the accumulator by pumping the pedal 40 times with the key off. Wait about two minutes for the brake fluid to de-aerate, then refill the fluid reservoir with DOT 3 brake fluid. 3. Now you can bleed the boost section. This is done by applying moderate pressure on the brake pedal and turning the ignition on for three seconds, then off. Repeat this a total of 10 times. Make sure the pedal feels firm when you have finished, and give the car a road test to make sure the brakes are working properly.

No brake pressure


Your complaint states that you see no air, is there fluid coming out of the left bleeder when bleeding the brakes? If you only see a few drops dribbling out, or nothing comes out at all...This can be a very difficult problem to solve. If this vehicle is a 1992 or later, it has rear antilock brakes, and if it is an ABS system, bleeding usually requires special equipment, and procedures. But there is something you can try. This takes quite a bit of time and patience, and a little bit of preparation. First you must realize that in the case of rear ABS, each rear brake has it's own fluid source, and plumbing from the ABS unit. If the obstruction is in the ABS unit none of the steps following will solve the problem, but you'll have to perform these steps to find out! DO NOT TOUCH THE BRAKE PEDAL UNTIL I INSTRUCT YOU TO HAVE AN ASSISTANT HELP YOU! USE PROPER PROTECTIVE EQUIPMENT! (Gloves, and eye protection, and protect your skin from exposure to brake fluid!) First we must know whether the flexible brake hose on the left rear is obstructed. The easiest way is to simply replace it, or if you don't want to start with a new part, you could disconnect it from the steel brake line that runs along the frame towards the rear of the car. (you don't have to remove it from the wheel cylinder first). Place a drip pan underneath the disconnected components. Now open the hood and remove the master cylinder cap. Make sure the brake fluid level is at the maximum height in the master cylinder. Now go back and look to see if there is any fluid leaking from the steel brake line. If there is not, then this is the point where patience is a virtue. There is air in the system all the way to the ABS unit. If the ABS unit is not obstructed or defective, fluid should flow by virtue of the force of gravity through the system and out of the end of the disconnected steel line, but if there is no fluid flow, it will take several minutes to possibly up to an hour and a half. If you have the patience to leave the car alone, maybe go to lunch, or to the auto parts store to shop for a while, gravity will do the bleeding for you. Once fluid begins to leak from the line, reconnect the brake hose and open the bleeder. Allow several more minutes for the wheel cylinder to fill and fluid to bleed out of the bleeder, then close the bleeder. Now do a complete bleed procedure using an assistant to pump the brakes while you finish bleeding any remaining residual air out. If you didn't get fluid from the bleeder, after you reconnected the hose, and after you waited long enough for the wheel cylinder to fill, then the brake hose is obstructed, and you will need a replacement brake hose. Once you are sure there is fluid flow, and no obstructions between the bleeder and the ABS unit, then you shouldbe able to obtain adequate pressure. If you can not get pressure, or fluid flow, you probably need to replace the ABS unit. There are additional procedures for ABS unit bleeding, but again, special equipment is required, so professional service is recommended.
