grinding sound coming from brakes

[timberghost159]

hello folks im new to the forum and want to thank you guys for all your help..heres the deal,, my wife has a 2002 cruiser she bought new..we had new brakes installed and still have the grinding screatching sound kinda like metal to metal when pads are rubbing rotors, it has made this sound for a long time and the mechanic said everything looked good and it was safe to drive. is there a problem with the cruisers having this problem or could someone tell me what i could look at to see if i can find the problem making this sound i did notice the front wheels is covered with brake dust so id say new pads but even after we replaced them before we still had this sound...your help would greatly be appreciated....

Make sure all the parts are on correctly.

thanks i'll pay close atten: to that part,,i've changed brakes on 100's of cars before but never this cruiser,,does the calipers pistons push in or screw in? anything i need to look out for and take caution to?

Never saw a piston that screwed in, the cruiser pushes in. Most of use a large "C" clamp to push open the piston when putting new pads in.

Also the biggest bit of advise I can give you is to not skimp on the pads and rotors. A few dollars more could save your life. Ceramic pads don't have brake dust, stop well and don't fade nearly as much as cheap pads. There's other good brands out there also. I use Hawk Performance Pads.

ok great,,yea i think it was a honda prelude i found out that the piston screws back in the caliper as does the pontiac fiero rear calipers...im gonna give it a shot in the morning i'll let you know how i do

ok i found part of the problem. the front pads were wore slap out. i cleaned both the calipers and all brake parts mounting brackets etc. really good. it stopped the massive grinding sound but in the rear brakes it still makes a real screatching sound not a metal to metal grinding sound but really squeaky sound. any ideas what that could be? it has had this noise for a long long time and the factory checked it and said????? everything looks fine. is this normal for the cruisers?

On my '01 the parking brake cable had rusted and the rear brakes were stuck partially on making a grinding crinkling metal sound.

this cruiser is a 2002 southern car never been out of GA. i also changed the oil and while under the car i inspected it real close, i found no rust at all it still looks brand new under the car..it only has 60k on it ,,parking brake seems fine, i put it in N and pulled the EB up and released it and it rolled freely,,i guess i need to pull the rear hubs off and inspect closely

Wanna know the source of the most annoying sound in the world? (Clip was thinner than paper.) See attached.

New clip, new silence.
