Check and remove a pin of switch from the master cylinder to allow the second piston to move back
read the instructions in the workshop manual or have an accredited brake shop do it

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.

SOURCE: Front brakes sticking on almost

A few items you could ckeck, adjustment of the pushrod from the pedal to the master [ if it's set to long, the pistons inside the master Cyl. wouldn't retact enough to let the fluid flow back into the master Cyl, properly causing the calipers to drag. this would become worse when the fluid and master heated up.], - The proportening valve may be faulty and blocking the fluid from returning to the master from the front brakes, - If the vehicle has Anti-lock brakes it could be in that system.
Good hunting!

SOURCE: Replaced all brake lines, rear

It sounds as though where the rear brake lines meet up with the master cylinder; there is probably a piece of dirt in the lines that could be blocking any fluid from getting in. To test this, I would remove the brake lines from the master cylinder and then remove the master cylinder. Once done, have the master cylinder cleaned inside out. This will remove the dirt particles that are clogging your lines.

Got an '03 Chevy Cav Sdn, new front pad,changed hydraulic line. Now brakes stay engaged! Can bleed off pressure thru bleeder, will not return fluid to master cylinder.Bled green fluid!Help!

It certainly sounds like the brake hoses are kinked or collapsed internally. Did you replace the flexible hoses or the steel hydraulic line? When you removed the calipers to change the pads did you let the calipers hang by the hoses or did you support them? When reinstalling the calipers did you make sure the hose wasn't twisted or kinked? The fluid certainly shouldn't be green, are you sure you're bleeding the correct thing?

1991 PATHFINDER Does this car have a proportional valve and would this cause front calipers to lock up?

Need year make and model. In most newer vehicles the valve is located in the master cylinder. It will not normally lock up the front wheels. It usually controls one front and one rear wheel at a time in the event of a brake fluid loss. If front calipers are locking up you could have seized caliper pistons/slide assemblies. The flex hoses may be deterioated internally due to contaminated brake fluid or the master cylinder may be defective

I am getting no fluid to my right front brake caliper on my 03 Kia Sedona any answers? New caliper and new hose installed?

hi shawn, have all the lines from the caliper to the servo been replaced. if they have are all the fitting tight. if not the might be a pipe at fault. is the bleed nipple tight before you try and build the pressure by pumping the brake. if all else has failed you could try a pressure bleed kit that gunson makes its a great tool for stubborn brakes. any mre info you feel maybe more help just let me know and ill try help you sort your problem.

Rear breaks not working I've tried bleeding over and over and the rear still isn't getting fluid I changed the hose also on the caliper I changed still nothing can someone tell me if its the metal lin

Its possible that the line has rusted. Diconnect the line working your way to the master cylinder. See if you start getting fluid. Or you could have something blocking the line at the master cylinder.

No fluid to the front calipers

Hi Friend:

#1) Check to see if the Master Cylinder Rubber on the Cap is Not Calapesed.And fits Even in the Metel Cap.

#2) Fill master up to MAX Level, Bleed Brakes Start with the Passenger Rear,Then Drivers Rear,During the Bleeding Make Sure to Keep Master Cylinder Full off & On.Bleed each Cyling until you get good Clean Fluid from the Blleeder Valves. USE DOT-3 Fluid.And Make Sure theres no Air Left in The System on Each Cylinder

#3) After the Rears are done Next Go to Passengers Front Caliper ,Bleed The Same Way here.Of course you'll need 1-Person Pumping Pedal during Whole Process.

#4) If you Are Still NOT getting Fluid out Of your Bleeder Valves in Front.

#5) Making Sure your Masters Cylinder is Full.You'll see bleeder Valves On MASTER CYLINDER. Loosen bleeder valve while someone is Pushing Pedal to the Floor.The Tighten before The Pedal is Let off.Keep it to The Floor Each time you Open Bleeder Valve.

#6) Do both Sides.If you still are Not getting Fluid from the Front Brake Bleeder Valves. Then Your MASTER CYLINDER is BAD Or your FRONT Brake Pads are Worn Down so Far your Caliper Piston is Bottomed Out.

#7) If this is the case Replace Pads 1st ,If not Fluid Still .

#8) Replace the Master Cylinder.

#9) After Replacing Pads or and Both,Flush out your Fluid from the Complete System until you get Clean Fluid from All your Blleeder Valves. With No Air In The System As Well.

Please Let me Know How my Solution has Helped you by Voting on the Quality Of my Solution.

Changing 4 calipers and there is no oil com out when try to bleed

The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.

Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.
