I don't know if anyone has ever run into this, but here's the problem. My husband has a 95 Z28. Everytime he goes around a left hand corner at high speed (like 25 MPH), there is a ear piercing screeching sound of metal on metal coming from the wheel. He bought brand new rotors and at first the screaching went away. After a few days it returned and he noticed a nice groove in his new rotor on the drivers side. It appears that the top of the caliper might be digging into the rotor. He has since replaced the brake pads, but after they wear down a bit, the screaching will return. Is the caliper shot? Why would this only happen on the driver's side? If you look on the passenger side, the caliper is about a half an inch away from the rotor. On the driver's side, the top of the caliper is a hair away from the rotor. It's not a question of are the break pads seated correctly, because he and a mechanic have taken them off and put them on half a dozen times. I have no idea what the problem is.

problem with the caliper mounting bracket maybe? (Normally they are cast if anything they will break completely which *should* be painfully obvious ).
is there any wheel bearing play? the caliper would be rigidly mounted to the spindle where the rotor and wheel ride on the hub assembly ( which in turn rides on the bearings). if the bearings were totally shot it could cause the difference in distance * theoretically* between the rotor and the caliper.
I'm kind of shooting in the dark here as it's nearly impossible to diagnose something like this over the internet.
this is kind of one of those things where someone really needs to look at it to see what's going on.Jason<br /><br />\'99 Pewter Camaro<br />\'93 V8 S-10

bearing wouldn't necessarilly cause a noticeable shake in the steering wheel. I've seen them where there were no other symptoms, except a strange noise that couldn't be traced to anything. replaced the bearings and the problem was solved. ( this was a hub assembly on a late 90's buick lesabre. )
In fact the hub that replaced it had the same problem ( autozone replacement. ) no symptoms other than the same noise coming from the left front wheel. Sent the defective replacement in and got a *second* replacement hub and the problem was solved.
the first replacement also had a faulty ABS sensor.
when it comes to automotive parts and repairs, there really are not a lot of set in stone causes/symptoms. a lot of problems can appear in different ways.
