Calipers float on bushings. These are round cylindrical parts, that resemble a thick tube. The caliper mounting bolts go through them, and the caliper slides back, and forth on these bushings.

Sometimes these bushings are worn to one side, and does not allow the caliper to slide.

Most of the time it's a sticking caliper piston, for this type of problem.
The easiest solution is to simply replace the caliper.

    If you have old hoses, maybe the one for front left brake caliper, has broken down. When the hose deteriorates pieces of rubber can flake off inside the hose. This will block the passage of brake fluid, not letting the brake fluid return to the brake line. (Hard metal line)

    This would keep the caliper in an 'On' position.
    Also spongy brake hoses can expand when applying the brakes. A Real dangerous proposition! You may clamp down on the brakes one day, in an emergency situation, and poof! There goes your brake fluid on the road!

    It's only money, right? Stuff grows on trees. Yeah, right!
    Even when a brake hose looks good on the outside, the inner wall of the hose may be deteriorating. Suggest you at least remove this hose, and check to see if a small 'flap' of rubber may be hanging there. Use an object you can gently poke in the end of the hose until you touch rubber. See if any of it comes out as flakes, or small chunks.

I have to continuously replace calipers on my jeep, what is the problem?


wonder if the rotors are too slim. If this happens the brakes get too hot as the rotor radiates away the heat. If too hot the brakes could wear out faster.

The left brake caliper sticks after my 97 lumina has been used for a while. I have replaced the master cylinder twice, both front rubber brake lines, and both front calipers.


Hi there...when you say it "sticks" are you think the pistons are not retracting in the calipers? Did you replace calipers with NEW ones or remanufactured/rebuilt ones? How about the caliper slides, did you replace those? About half the time this is the problem on a sticky caliper that is causing excessive brake wear. If they are off just a little bit & no longer "true" the caliper will bind and the brake pad will steadily rub on the rotor. They need to lubed with disc brake grease and the protective boot needs to be in good shape to keep the brake dust and debris out too. This is an inexpensive part, easy to replace and often overlooked by shop techs. Good luck, i hope this helps. Thanks for using FixYa!

My front driver side brakes are sticking. the rotor is heating up and the brakes are being worn down. i replaced the brakes, rotor, and the caliper.


99% of the time that is caused either by the slides on the caliper being frozen with rust or the rubber hose between the body and caliper has an internal failure and is keeping the caliper applied. Less common is the piston in the caliper being rusted or an abs system that has gone bad.
Personally I'd bet on the hose.

First you must look closely at the caliper and determine if it is sticking on the slide or is the piston sticking. If it is the piston you would have to rebuild the caliper or replace the caliper. If it is the slides, you need to sand and clean all the slide contacts and lube the slide with lithium grease or never seize grease. Then you can reinstall the caliper and you will be fine. Also when checking if the piston is sticking try loosening the line and see if it retracts, if it does you may have a bad flex hose going to the caliper holding pressure on the caliper.

Driver side front brake rubs and overheats. brake


It sounds like the caliper slides themselves are sticking, remove your caliper and check that the caliper slides are lubricated and that the caliper slides easily on them

Front left brake keeps locking up


i suspect that you have a bad caliper which is sticking. look there first, and always replace both if on the front, since murphy's law usually applies. thats where 60% of your stopping power comes from. the anti lock system won't normally cause the problem you describe, but a bad caliper will. make sure the rotors are ok as well.

Caliper is sticking


the ABS valve in the ABS hydraulic control unit is leaking pressure and causing brake to apply is the most likely thing wrong..
