The caliper might be sticking
If the front brake caliper is sticking, the disc may be uneven. Brakes that are left to scrape on the disc for a long time before they are changed will damage the disc enough to cause sticking or slipping.
brake caliper is sticking due to faulty caliper or rubber brake hose.
STICKING BRAKE CALIPER
Defective caliper, restricted hose, caliper sliders sticking, contaminated brake fluid (probably not contaminated if only 1 front caliper).
Your brakes are sticking could be either the brake caliper or the hose going to the caliper
The main cause of uneven wearing brake shoes is a sticking or stuck caliper. Check to see if the caliper is releasing properly all the time.
because the brake caliper is sticking or rear brakes are sticking
The caliper is probably sticking. With the car jacked up and on a jack stand and the wheel removed, see if you can turn the caliper. You can probably see what's sticking this way.
first replace brake fluid if that does work take off caliper spray it with wd40 n move it in n out that should solve the problem.
1. Remove the brake hose to caliper bolt from the brake caliper. 2. Remove the brake hose from the brake caliper. 3. Remove and discard the 2 copper brake hose gaskets. These gaskets may be stuck to the brake caliper and/or the brake hose end. 4. Cap or plug the opening in the brake caliper and the brake hose to prevent fluid loss and contamination. 5. Remove the 2 brake caliper pin bolts. Remove the park brake cable from the caliper. 6. Remove the brake caliper from the brake caliper bracket.
two possible causes......it could mean you have a bad brake hose or a sticking caliper
