There is a problem with your master cylinder that need urgent repair/replacement. To get moving in a emergency open the bleed screw at the caliper to release the pressure and tighten again. The vehicle should be able to move again. However as soon as the brakes are used the caliper will lock again as the master cylinder will not release the pressure again. Do not drive the vehicle like this. Only release the caliper for towing the vehicle to a repair facility.

SOURCE: 1980 Chevy Truck Brake Locked Up

There are times when the rubber brake lines start to come apart internally and act like a one way valve. they let the fluid in, but will not let it out.

Try this: The the brakes are locked up release the bleeder on the caliper. if pressure come out there, lock up again, and release the hose where it goes into the metal line. This may be hard because of rust, but you will probably have to replace the line anyway.

You may have a bad Master, but odds are it is the rubber lines. Hope this helps.

SOURCE: 1994 Toyota pickup front brakes don't release

Well I don't think you'll need to buy parts,it sounds like there may be sludge built up between the master cylinder and the proportional valve to the front brakes.Pull the valve off(follow the line off the master cylinder and you'll find the valve)clean it and then flush/bleed the master cylinder before you reinstall,Then flush/bleed the rest of the system.There's a relly good chance that may be all you need to do,but you may need to pull the calipers and clean them also.Comment back if you need more help,Good Luck(To)Yotaguy

I have a 2003 Chevy Tahoe I changed the rear passenger side brakes line rotor caliper and all that why does that side continue to wear faster than the others


There could be several reasons that might occur. Has the vehicle been in a wreck? If so that can cause issues. It could be a blockage in the brake lines so that the pressure releases slower than the other brakes. It could be that the rotor os damaged or that the caliper is damaged. It could also be that the rods the caliper and brakes ride on are bent or damaged. I am sorry I can't be more helpful but the question is kind of broad.

1988 Chevy scottsdale front brakes locked up brake fluid full help


If your brake hose collapsed internally that will cause brakes to lock to be sure its the hose and not the calipers open the bleed screw and see if the rotor release. If they stay locked then maybe calipers seized try to pry brake pads apart with caliper mounted and brake bleeder open if they return easy then change your brake hose.

Hello uncleel03,

There 3 item to look at:

1. Are the caliper mounting slide pins free and lubricated?
If not, the pins and bracket s need to be cleaned and lubricated.

2. Was a new hardware kit installed on a clean caliper mounting bracket and do the brake pad move freely in the bracket?
If not, the bracket needs to be cleaned and all rust removed from where the hardware kits attaches to the bracket.

3. Did the pistons in the calipers compress easily?
If not the caliper may need to be replaced. I say "may" because a bad brake hose can cause resistance when compressing the caliper so you will need to isolate the cause of the resistance.

Testing:

Safely lift and support the vehicle.

Have an assistant press and hold the brake peddle while you try to turn the wheel; as you are trying to turn the wheel have the assistant release the brake peddle, the brake should release immediately and the wheel should turn freely if not there is a problem with ether the caliper or brake hose.

To determine where the fault is you will need to remove the tire and have your assistant apply and release the brake. If the brake remains engaged open the bleeder if the brake releases the brake hose is the problem and needs to be replaced, if not the caliper needs to be replaced.

Repeat this procedure on the other side to determine it's integrity.

Of course you will need to bleed the brakes after these tests and after the new parts are installed before you can drive the vehicle.

I hope this help.

Regards,
netvan

2002 chevy tahoe z71, passenger side brakes are intermittently dragging, brake pad smell.


Your problem indicates that the right caliper has failed. Assuming it is the right front brake, you'll need work done on both front brakes at a minimum. Have them change out your fluid when you get the work done as old fluid could have contributed to the failure.

Hello, i replaced the brake calipers on my 2002 chevy Tahoe, now i cant get any fluid to the calipers. I even tried the suction tool still nothing.


take the line loose at the hose if you get fluid change both hoses they might have been the reason the calipers needed to be changed also check to make sure you didnt twist the hoses because this can also pinch off fluid hope this helps good luck

I have a 1999 Chevy Tahoe and my driver side wheel is locked up. Changed the brake caliber, brake pads,brake line, no air in the system, could it be the abs system and if so how can i fix it?


If you have'nt yet replaced the flex hose going to the caliper then it may need to be replaced or unfoald the clamp the hold it to the strut to release the blockage caused by rust build up,if there is no wheel speed picked up by the abs then it does'nt come into play.

Brakes


Did you change the pads, pistons or calipers or the whole set? if you changed just the pistons, did you hone the cylinders? I don't know if yours have them but there were some vehicles(ford) that had non-metalic pistons that kept seizing/not releasing after the breaks were released.
