97 Bonneville SSE Rear Drum Brakes/ Buildup/ Grind Noise - ?
I am new to your forum and was introduced to it by my friend BusMaster007 who just got a 92 SSE, otherwise I would not have even looked here, great site!
Well I have done some searching but haven't found what I have been looking for so here it is...
On our 97 SSE, 92K miles,we have a "grinding or dragging" sound in the rear drums.
Since I had had the brakes done at a Les Schwab (we were going on a trip and I didn't want to mess with the brakes) . The front rotors were replaced and I was told that the rears had 75% meat on them and drums were fine, so I drove out.
I didn't go far and I noticed that the rears still had the same sound when stopping, so I returned and witnessed the inspection, sure enough there was a lot of shoe left and the drums were in good shape, I would have agreed that there was no reason for alarm, yet the mechanic did drive it with me and agreed that there is a reason for the sound and yet could not explain not seeing any problem.
So we cleaned the smoothed brake shoe surface, which has a hard buildup, with crocus cloth and did the same to the interior surface of the drums, he reassembled and I took off, stopped and there was no further noise as before.
Problem solved I thought, yet only a week later it was back!
Now as a former professional forklift mechanic (Caterpillar) I do know that there are several brake compositions and that the hardest linings will also act like this, and also cause hard braking if it is really hard material.
So I am asking if there are diferences in the brake shoes available from dealers or aftermarket sellers, OR if there are other items to consider, (rear brake adj. not close enough?)
Thanks and will await replies...
