[DML] Re: squeeking noise

["Harold McElraft" <hmcelraft@xxxxxxx>]

I believe you have a sticking caliper piston. It is probably not 
backing away from the rotor adequately and, when things get warmer, 
the piston probably releases even less after you apply the brakes. 
Was one brake pad worn more than the other? That is a sign.

I get a squeaking sound (rhythmic) from my driver side rear every 
now and then, even with PJGrady's release springs, because of too 
much rotor run out. But I don't get any pulsing, etc. so I'll just 
live with it until I need some new rotors.
