Yesterday, my front left modified BMW 320i caliper began squeeking when pedal is off and going slow. Hit the pedal a couple of times and it went away. Got home and checked to see if caliper was hot. Pretty hot.

Is there a quick fix to this; or does the caliper need to be removed and sent in ?

Had this happen two weeks ago.

Jack the car up... pull the wheel. Pull A pad out... it'll take some effort.

Using some wood in place of the pad, stomp on the pedal.

Pry the piston back. Repeat. Then repeat process with other pad.

Hopefully, you can break the stuck piston loose. If not, you can probably rebuild the caliper yourself.

Thanks for the headsup; Do you lubicate anything after prying ?

What causes the sticking ?

I'll try it tomorrow after work

Nope. No lubrication.

Rust in the cylinder bore usually causes the cylinders to stick. You can usually polish it out with some 400+ grit sandpaper when you do the rebuild.

If you can R&R a caliper, you CAN rebuild the caliper. Recommend you do both both calipers on the same axle. Invest in a couple cans of brake cleaner to help clean things up.

Before you do all that, hit the pedal hard, check the drag after it's released, then hit it again, release it, and crack the bleeder. If the drag is released, replace the front hoses with nice new OE rubber ones. The Cap'n

Do you think there is a defect in the hose ? Interestinly, the squeek ( rubbing againgt the rotor) alway returns when I brake to make a 90 degree turn. Would that make sense ?...

Thanks.

Could be kinking the hose when turning. If you don't know the condition of the hoses, it wouldn't hurt to replace them. They're not that expensive, and the front ones are easy to replace. The back hoses, on the other hand, not quite so easy.

Hmm.. thank you.
