Subject:      Need advice on Brake issues
Content-Type: text/plain; charset="us-ascii"

Guys, I need your advice on a brake service issue. Took my just purchased 91
GL in for safety check to get plates in Ontario.

Brakes worked perfectly on the way in. I was told rotors were below VW spec,
so they were replaced, and I sprung for pads also. Rears were 'just in spec'
so we left the rears alone, just serviced/lubricated them. Also changed
fluid.

When I got it back there was a pulse in the brake pedal, speed dependant.

Garage position: The drums were out of round. And these contributed to the
pulsing. Sticky caliper also. To fix, need to change drums and maybe
calipers.

My position: Brakes were perfect on way in, so something changed. The rears
didn't cause a pulse before, so how can they now?

Sticky caliper doesn't create that symptom does it? I am thinking the only
source of the pulse is a warped rotor installed by the tech.

What do you guys think?

Thanks.



Mark
