Just had brake discs new pads fitted to mr2 back end making a scrapping noise ?
Answers:
TO REPLACE BRAKE PADS YOU MUST AT THE SAME TIME REMOVE ALLRUST AND ROUGH HIGH SPOTS ON THE FACE OF THE DISC. CENTER AND ON THE OUTER EDGE IF YOU DONT THE HIGH SPOTS WILL WEAR A GROOVE IN TO YOUR NEW PADS. IE. RUST THAT IS USE SOMETHING FLAT AND YOU WILL SEE WHAT I MEAN .UK DRIVER
Have your mechanic look at them.
take it back to whoever installed them, they screwed something up.
The mechanic either put them on too tight or they didn't put them on at all and wanted you to come back and spend more money.
This is probably due to them not cleaning the surfaces before they installed them. They should have wiped the excess dust off of the pads and applied some sort of anti-seize/squeak gel to the back of the pads to help avoid that. Also, they should have rubbed the rotors down lightly with some sand paper to take off the polish that the rotors are shipped with.
Sounds like they missed some steps.
had the same thing once the disc had a score mark in them from old brakes had it sanded out problem gone
if you had new discs aswell as pads there is no excuse for a noise but if you had just pads they might need a bit of bedding in to make there surface mate with the discs. the fitter should be told but i expect he will say let them bed in a bit. dont drive the car if you think the brakes dont work as good as they did before. pete
by your rather poorly worded question I'm assuming that you just have brake pads only installed on the rear of the car.if you or your "buddy that's a mechanic" did it and just did a pad slap there are many reasons that the make noise..the kind of friction material on the pad as well as the quality.if you use a CHEAP AUTO ZONE pad, that's a good reason.were the rotors measured and machined..(you don't use sand paper) they should be machined on a brake lathe.if not machinable because there too thin or the facing is rusted..replace them with new.not new used.all the contact surfaces must be cleaned and lube with the proper lube..NOT GREASE..inspect the caliper hardware and replace if necessary.or here's a thought take it to a professional and have it repaired correctly.
WARRANTIES- are a great thing!
