Brakes squeal when cold

[dekeman]

Hello all,

I've been hearing a metal-on-metal squeal when braking in the mornings that goes away after a minute or so (after they get hot). It's loudest when backing out of my driveway (~ 30 yds) and braking before getting into the street. The temps up here in northern NY are cold- low teens and lower most mornings.

Anyhoo, the front pads were changed a couple of months ago and I applied the anti-squeal goo before mounting the pads. I did not replace the pin grease, so that may have something to do with it. I had the rotors machined and cleaned it all with plenty of brake cleaner spray before finishing the job, so there shouldn't be any grease contamination. It may be the pad material too. I got decent quality Wearever pads, but not ceramic. I heard on another forum that this is normal noise and that I should just live with it. Whatever.

I plan on getting in there this week and re-greasing the pins. Any other ideas? Just want to be sure that this isn't indicative of some catastrophic fault that will hit at the worst time (like during a snow storm).

Do you park outside? Might just be surface rust on the face of the rotor getting "cleaned" off.

No, I park in an unheated garage. I'll look for rust spots on the rotor before I head out in the AM, but I don't think it's that. It never used to make that noise when I did park outside (and in a wetter Virginia climate). It could be that the salt and sand on the roads affect the rotor. I think it was the pad change and the lack of new grease on the pins. I'll have to check that the rubber boots around the pins are still sealed.

Noticed your sig mods. I've been looking for Dave B rings for some time now. I'll have to post a question on where to find them. I just got my 03 LX a year ago. I'm behind the power curve! The shaved side mouldings are interesting too. Looks like there's a view of them in your pic. I like my laser blue as well- the coolest car color ever!

I got the rings last April through www.ProtegeGarage.com. I think it was a limited production group buy.

The non-greased slider pins could also be a contributor. My brakes used to squeak when I backed out of my garage before I replaced the rear pads and greased the slider pins.

Laser Blue isn't only the coolest, it's also the fastest!
