1995 Park Avenue. The diver's side front disc brakes started overheating to the point that they were smoking. Upon inspection, I found that the inside brake pad had worn down much more than the outside pad. I removed the caliper from the wheel to replace the pads and found it nearly impossible to compress the piston even with the bleeder loosened. I figured the caliper was shot, so I bought and installed a new one. Now a few days later the brakes are overheating again. Can someone suggest what might be causing this?

Thank You

 

I would be very suspicious of the brake hose for that caliper.
If you try to depress the caliper piston and have the same problem , try loosening the brake line at the connection where the hose connects to the metal line by the chassis.
If you can depress the caliper piston now , the hose is the problem and needs to be replaced.
Let us know what you find, thanks.

 

Thanks for the response. A couple of people in another forum told me almost exactly the same thing. Looks like I'm off to get the brake hose.

 

This could all be good, but we like to prove our suspicions before going out and buying things. There could be other possibilities, but the worst thing you would have had to do is remove the wheel to get to the connection and spread the caliper. Let's hope that is all it was.
