Front passanger caliper locking up

If your front passenger caliper is locking up repeatedly, there could be a few potential reasons for the issue. It's essential to consider both the caliper and the master cylinder as possible culprits:

Bad Caliper: It's possible that the rebuilt caliper you installed is defective or has a problem with the internal components, causing it to seize or lock up. Even rebuilt calipers can sometimes have manufacturing defects, so it's not uncommon to encounter this issue.

Master Cylinder Issues: A faulty master cylinder can also cause a caliper to lock up. If the master cylinder is not releasing pressure properly, it can lead to brake fluid remaining in the brake line, keeping the caliper engaged.

Brake Hose Blockage: A blocked or collapsed brake hose on the passenger side could also cause the caliper to lock up. When the brake hose deteriorates internally, it can prevent the fluid from flowing back and releasing the caliper.

Caliper Slides and Pins: Sometimes, the caliper slides or pins can become rusted, corroded, or jammed, preventing proper movement and causing the caliper to lock up.

To identify the exact cause of the issue, you can perform the following checks:

Inspect the caliper and its components, including the slides and pins, for any signs of damage or improper movement.

Check the brake hose for signs of blockage or collapse. Ensure there are no kinks or restrictions in the hose.

Test the operation of the master cylinder. Look for any signs of fluid leaks around the master cylinder and check the brake fluid level.
