Rear brake squeal

[wingnuttyz]

My rear brakes (non S) are squealing under light braking and sometimes hard braking too. Had the dealer check it out and there's 65% left on the pad. They also said the squealing is normal. Dealer default answer. Well this weekend it was squealing so bad it sounded like a bus. Yesterday I remove the pads and calipers and cleaned everything out with brake cleaner, used caliper grease on all metal contacting parts, and put a little Permatex brake quite paste on pad backing plate.

I thought for sure this would solve the problem but once the brakes warmed up they started squeaking again. Does Porsche sell anti-squeal shims for the base model boxster? Any suggestions would be greatly appreciated.

Oh yeah also noticed the inside pads were not being compressed by the inside caliper pistons when I was removing the pads. There was a slight gap. Is that normal?

This is NOT normal!

When you looked at pads, any glazing or spots?

Rotars smooth or grainy? Any grooves to speak of?

You're within spitting distance of Jeff, or TOOLPANTS in San Jose. I'd PM him and ask him if he might be able to take a look at your brakes or refer you to a good independent mechanic who works on Boxsters in your area.

My brakes squeak from time to time, but a good blast with a water hose on the rotors seems to clear it right up.

ARGGGG!!!

I have the SAME freag'in problem!

I have a 2000 Boxster S as it make the same squeel when I creap to a stoplight. There's 50 % pad left, no grooves or vibration in the peddle or steering. When i wash my car, they don't squeek for 3 days then it starts again.

WTF?????

Just got back from the dealer to see if they had any ant-squeal shim for the base boxster. No luck only available for the S brakes. Ask the service guy about it and again he said it's normal. He said his S squeaks everyday.

The pads look like normal wear, no vibration, and the rotor have very minor grooves like the front, but they don't squeak.

Has anyone with the same problem tried changing to new/different pads or used Weltmeister brake pad liners to stop the noise?

Since the Permatex quiet brake goo didn't work I'm going to have to scrape that stuff off calipers and pads this weekend.

Sorry, this is not normal on all S. In fact, I have not stocked one yet that did this.
