All,

My 93 400e is making a thrumming noise from the front that goes away when I touch the brakes. I suspect a sticky front caliper.

Since new calipers are so expensive ($750) I am going to attempt a rebuild of the old ones. I have the kits.

Any input about caliper rebuild in general, or information about who could do it, would be greatly appreicated.

tia,
