Brake caliper sticking

Hi, Joel. I need you to test something for me. You will need a helper.

Safely lift the driver's side affected wheel off the ground and spin it by hand. Next, have a helper apply the brake so you can't turn the wheel. When the brake is released, does the wheel turn easily? If not, open the bleeder on the brake caliper and see if it then releases.

If it does. Replace the rubber brake hose to that caliper. Over time, they can break down internally and restrict the return of brake fluid when the brake is released.

____________________________

If you find the hose needs replaced, here are the directions. The attached pics correlate with the directions.

If this doesn't help, let me know. It may have to do with the slide pins. However, since you replaced the caliper, I suspect that has been checked.

Take care,
Joe
