Noisy Brakes

[marbs]

Whenever it's hot or my brakes heat up they squiel like a siv cuss . Also if I'm going slow(UNDER 10mph) they squiel even when I'm not hitting the brakes oh_my . Is this normal or is something wrong????????? shrug

have you chamfered the pads ?

I was just gonna suggest that.

That, and some anti-brake squeel spray works wonders. It's a spray you put on the BACK of the pads that keeps them from squealing, works wonders.

All auto parts places have it, $3.

Oh yeah, and sieves don't squeal, they leak.

ive been having a horrible time with squealing pads. first thing i did was switch to non-organic and non-metallic pads (i use raybestos). my rotors were also not helping because they were warped in the back. now only my right rear brake is squealing and i think the caliper is shot because it doesnt lock the wheel when i pull the e-brake. im replacing it tommorow morning so ill let you know. also make sure all youre lug nuts are torqued properly. uneven pressures on the rotor can cause squeaking. good luck!

What does chamfered the pads mean? Sorry I have never heard of this before. Is it a spray or is it something you fisically do to the pads?

chamfering pads = filing away the 90 degree angle at which the leading edge(s) of the pad contacts the rotor. do accomplish this, just use a metal file and rasp a chamfer of 45 degrees or so. it doesnt have to be exact, any angle will suffice. what this does is break the harmonics created by a perpendicular surface contacting the rotor. that is what is a main cause of brake squeal. it will also reduce the amount of dust thrown out onto the wheels and such. however, it wont reduce the life of the pads. only in rare occasions will it extend the life of the pad. that said, given you have new/turned rotors installed at the same time. ive done this on every brake job i have done. this includes rear shoes on drum brakes too. the only exception is on pre-chamfered pads, such as the Performance Friction Carbon Metallics available for the front, which are already chamfered through the life of the pad. also, when you chamfer the pad, get as much as you can. normally i try for 1/16" obove the backing plate, so i dont have to do it again til the pads get replaced.
