Perportioning valve under the master cylinder may be stuck it is usually directly under the master cylinder(follow the lines down to it) this sends more fluid to the front than the back and will stick.if bad.. replace it..good luck..

It can be the rubber brake lines. When the insides of the brake lines collapse they act like flap gates and stop the brake fluid from returning to the Master cylinder. You only have one-way pressure to expand the brake parts. The return of fluid depends on Gravity and suction. Also all rubber brake lines have ridges molded into them. It is easy to twist those lines when rehanging the Calipers. The brake line ridges should be hung parallel to each other.

Your Master cylinder can be bad. It can hang up and then gradually release. But same goes for rubber brake lines with the problem I mentioned.

Please rate my info.

SOURCE: Front Brake Pads locked up on Rotor

Have the brake pads been so very work they are down to the metal? This could cause the caliper piston to extend too far and not be able to retract properly.
Calipers Fail mostly from a cut in the rubber boot around the pistion dirt and debris get in there and rust the piston and it cannot retract properly Do they retract after they cool Down? if so the brake fluid has "boiled" if brake fluid is not changed about every 24,000 miles condensation builds up and lowers the boiling point of the brake fluid causing this problem.
Tell me does it happen after a long drive or siting a long time in heavy bumper to bumper traffic in hot summer weather? I recommend a complete brake fluid flush an change the calipers with NEW ones ot rebuilt and use dielectric grease on all points of metal to metal contact between the caliper an the mount bracket and thee ends of thee pada n the slide points they ride on and the pins that go through thecaliper and thread into the mount only dielectric not regular grease it will cause sticking and a worse problem than you have now.

There are 2 bolts on the "inside" on the caliper towards the bottom they use an allen wrench socket.

SOURCE: 2008 grand caravan rear brakes

Older vehicles with caliper parking brakes rotated their pistons in a ratchet effect.To retract those they needed to be pushed in and rotated at the same time.I cannot stand rear disc brakes.Seems they fail way too often.GM had that issue with its W body cars (1987-up),pads would wear to steel in 6 months or less. Did the face of the piston have 2 or 4 square/rectangular/round holes in it? There is a tool to hook onto a ratchet to let you turn and push the piston back in. If you banged it in, the system may not work correctly.
Go and rent the Caliper Brake Kit from Auto Zone, it make your brake job way easier. This tool compresses the piston while it rotates clockwise. So if you are going to do your own rear brake job get this tool or something similar. 
Good luck and hope this helps. Keep me posted, Recap: The cylinder does not compress on the rears, it screws back in. A special tool for rear calipers works best but a pair of needle nose pliers will do in a pinch.

The piston must be rotated as it is pushed into the caliper. There is a special tool for this that is sold at just about all parts houses. The tool looks like a small square with various pins for various applications that goes on the end of your 3/8 drive ratchet.

What is next? Brake pressure is non-existent on all but front left. Pedal pressure is very hard. Replaced all calipers and master cylinder. Fluid does not exit nipple when bled on all but left front.


Its possible that your rubber lines are collapsed. I've had them keep fluid from going thru as well as not releasing pressure. See if fluid gets to caliper thru rubber. You can plug it with your finger and release pedal. If you feel vacuum and fluid flows well when you push brake, that's probably not the problem. Its somewhere to start tho.

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

Rear caliper on 2005 Ford F150 not releasing, replaced both rear calipers, now pedal goes to the floor - no brakes at all. What can/should i do?


Sounds like it still has some air in the system or a bad master cylinder. First try bleeding all air, there is definitely some air left in the lines and this is most probably causing the problem. Bled the lines at the bleeder screws on the calipers. ---------- There is air left in the brake line.Any time the brake system is opened to replace brake lines, caliper, pads etc etc.Mostly the air enters the system, and that air has to be completely bleed.Otherwise the same symptoms , what you are getting will be noticed.-------- Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder.IIt does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets.----
The most common bleeding procedure is to bleed the 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 truck, 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.--------- When the complete air is bleed from the line, the brake should be firm when car is on.In your case brake brake pedal is loose and goes almost to the floor when car is ON.This is due to Air in the line.Get the complete air bleed from brake line.------- This will help.Thanks.Helpmech

After replacing drive side caliper, both front disk brakes, and rear drum brakes, bleed all three lines, both my front calipers lock grinding my front brakes. I am going to re-bleed my lines tomorrow but...


I assume you mean that you replaced the front pads and rear shoes. Or did you also replace the disks and drums?? Either way you should be ok unless you also replaced the slave cylinders on the rears.
The fluid flows back up to the Master Cylinder as you squeeze the calipers and the slaves to fit the new parts in. Some people pre-fill the caliper to reduce the amount of air and make bleeding easier.Now .....Grinding better be a wrong choice of words. Possibly you spilled fluid on the pads while bleeding the lines. This will cause a binding and shuddering when you apply brake pressure. This will also make you think the lines are not bled properly because of the increased pedal pressure you are putting on the wet/lubricated front pads. If so, replace the pads. Don't try washing them with aerosol cleaner cause it takes more time and money than simply changing them.

Pistons in both front calipers stay out, both calipers replaced


You may have a leak in the booster or master cylinder. You can put a pressure tester on the system to test for leaks. It does sound like you have an air leak.
You can try to bleed the master cylinder, then slave cylinder, then brake lines.

Brakes are still spongy after changing the pads, one caliper, and master cylinder. bled front brakes.


I just went to Brake Masters this morning and had them replace the Master Cylinder since I was experiencing the pedal very spongy and going to the floor. When they replaced the Master Cylinder and they gave me back the car, the brakes were still spongy and going to the floor. I addressed this to them and they took another look at it, but when I took it for a second time, the brakes were extremely spongy. It was almost like they gave me back my car in worst condition to when I brought it in. Can you help?

Brakes to the floor(almost) 99 blazer


bleed the brake again. if the pedal goes to the floor with little resistance, then the master cylinder is your problem.
the shim is to depress the noise when you applied the brake. you can skip that, if the brake works without it.

Replaced brake pads 99 Mustang 35th Ann now they are locking up


you have either calipers hanging up or the lines are separated on the inside causing the fluid to not be released back after application of the brakes.. to test... remove the caliper on the pass side first (farther from master cylinder) and slowly try to push the piston in using a c-clamp.. if it doesnt go in SMOOTH then crack the bleeder screw, and try again, if it goes in just fine its the line.. if it goes in the first time fine then go to the other side and try it. if one of them DOESNT go in fine with the bleeder broke open you need calipers (very common) and then you will need to bleed the brakes and make sure to start on the side farthest from the master cylinder i.e pass side
