Help guys,
I am hearing a faint rhythmic scrubbing sound as of last nite coming from my silverado. Its only noticeable when coasting thanks to Flowmaster exhaust. The truck has 87K on original brakes. In addition I just noticed that my rarely used parking brake now fails to hold the truck stopped when its in gear.
Please throw me some knowledge guys.
Thanx

 

It could be a number of things....

I had the same problem on mine a while ago and it turned out to be a loose cap that covers the axle nut in the front (In the center of the brake rotor/hub assembly). I replaced it with a new one and had no problems. It only cost like $2 for a new one.

It could be a number of things with brakes like: Warped rotors, warn pads or cheap pads, or a lack of lube on the caliper guide pin bolts.

I would check those areas first to see whats going on.


My parking brake does the same thing, so let me know if you find a solution. I haven't really tried anything on mine yet though.

Hope this helps.

 

There's some good info on the parking brake problem in this thread

Mine used to be the same, complained enough to the dealer that they ended up replacing a bunch of stuff while the truck was still under warranty. Been working fine since then, like 2 years ago.

 

My truck made that noise too before I changed the brake pads. Of course it'll also make that sound if the lug nuts aren't tightened down all the way.
