Occasionally after driving and stopping my right front brake caliper is slow to release,a few times it actually stayed applied and become extreamely hot. When this happen I opened the bleeder screw relieved the built up pressure and the caliper released the brake pads and the wheel was able to turn free. This is the only wheel that is sticking, and I thought if the caliper was sticking, opening the bleeder wouldn't have any effect, what say you?

if the caliper is ok it sounds like the flexiable hose is restrcted by the metal crimps on the hose corroded and crushing the reinforced rubber hose restricting the fluid returning back in to the system. change the hose

may have a seized hand brake cable

sound like you have a brake caliper that has went defective.need to replace this item and should take care of the problem.because when you applied pressure to the brakes the brake caliper started to close so the brakes could tighten against the brake rotor to slow vehicle down and some times these calipers will stick down holding pressure on the wheel disc and cause the wheel to still have the brakes holding down the brake shoes against it not letting pressure to release from rotor and this is what caused it to stay locked up its not releasing to allow to allow wheel to spin free.best bet is to replace the brake caliper.you can pick one up at parts place or local junk yard and are not highly expensive but I would go with new one if possible. to insure this does not happen again this is very dangerous could cause you to have a accident so I would get fixed before driving again.safety first .hope this helps you out so I would replace the brake caliper and also put a new set of brake shoes on it.its not hard to put on easily fixed. thanks 10 zacks

Your problem is half normal actually. Pumping the brakes will build more pressure in the system and will make the pedal harder and the brakes will brake alot more, the brakes are designes this way. But if the brakes don't release after you let go of the pedal, that's not normal. If this is the case, there may be a few things that can be faulty, but i'd start by checking/replacing brake vacuum booster unit. If the unit is ok, then probably one of the calipers on the brakes are starting to jam due to rust and dirt, especially if you see the the rubber seals on the caliper pistons are damaged or missing.

Jack the vehicle up, off the ground and check each wheel to see if there are any brakes binding on.
If you find one binding, then release the bleed nipple on that brake and check again. If the brake becomes free, then you have an issue with the ABS pump. If it makes no difference, then that brake is stuck. You'll need to try pushing back the piston on that brake. If it's stuck, then free it or replace it. Also check [if it's a caliper brake] that the slide pins are free and lubricated.

If you have no brakes binding, then you may have an issue with the ABS pump.

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.

most common cause would be a bad disk brake caliper, or bad brake hose.

the way to find out witch one, is to jack up the front of the car and put it on jack stands. put the transmission in neutral. then turn the front wheels one at a time and wile turning the wheel have some one apply the brake the wheel should stop turning immediately and then wile applying pressure on the wheel have the person in the car release the brake pedal the brake should release immediately if not, then open the brake bleeder on the offending caliper if the brake releases then. you have a bad brake hose if the brake still does not release with the bleeder open then you have a bad brake caliper.

GOOD LUCK

sounds like the pistons in the brake calipers are rusted.(you can check this by looking sideways into the brake disc/pistons,if so replace both sides together (easy job for two people.you need 2nd to help bleed brakes) if your not into diy then do not attempt this job.....safety

Jack car up, spin wheel, then apply brakes, and release and try spinning wheel again. If it doesn't spin just as easy, try cracking bleeder screw open, then try spinning wheel. If it spins easy after you crack bleeder screw, tighten bleeder back up & try same again. If same result, wheel spins when bleeder opened, then I'd replace the 2 front flex hoses that attach to calipers. If caliper doesn't release then you need to pull calipers and check if partially seized, or maybe slide pins that caliper moves on (that attach caliper to spindle) need cleaning and lube applied to allow calipers to move back & forth.

Probably a restriction in the brake line from the master cylinder to the wheel.

Most of the time brake hoses do this (collapsed hose or hose inner liner) but the restriction could be anywhere from the point your front brake pressure divides to both wheels to the caliper of the wheel. The problem is not the caliper itself because the bleeder is able to relieve the pressure.
