New brakes are noisy

[PurplePTGirl]

I just had my front brakes redone. The rotors were turned and resurfaced, and I installed new ceramic pads. When I brake, I hear this sort of whine that sounds like a motor spinning down (a whirring sound).

Is this normal with ceramic pads?

Have had ceramic pads on 3 different PT's, have never had that kind of a sound, I'd suggest returning to the Shop and discuss the problem with them.

There's an anti-rattle metal piece that could have been left off or even put back wrong. But I agree with Hooligan. Take it back and let them fix it.

I put ceramics on both my PTs.
No noise!

When you returnj to the place that did the work, ask them how they "bedded" the brakes. I have read that ceramic brakes are more fussy about bedding. I can't say one way or t'other, since I am using my first set of ceramics (and I don't like them.)

Bedding brakes requires making several abrupt stops from about 60 MPH to about 10 MPH, but not to a full stop. Some ceramic brake instructions call for four repeated stops.

I can truthfully say that brakes take a while to break in, and that the bedding really helps.

Does the whine happen all the time? Does it only whine when you are using the brakes? Does the whine go away when you give the brakes more pressure? (That can indicate that the pads are vibrating and might benefit from pad adhesive that sticks them to the caliper.) Was the previous set of brakes ceramic?

The whine is only when I am using the brakes, at the end of the braking period--moments before I come to a stop. The whine increases with more pressure. The previous set was NOT ceramic.

Havent had a chance to take it back yet so I dont know how they were bedded. Should they replace these pads? I have usually had good work done here but I dont know... I have never heard my brakes whine before.

I have put 3 set of ceramic pad on 3 different PT's. I have NEVER had to "Bed" them in. They didn't whine and I just used the brakes as normal. Never had a problem as they "dust" much much less than OEM's. Never heard of "bedding" in brakes other than the normal composition ones.

I wouldn't worry about a whine or squeal or squeak. If the brakes stop the car, that's the main goal. Have the shop check it out.

Same here, and bedding was really useful with asbestos brake shoes and pads, when they were still available. The instructions that came with the ceramic pads I bought suggested bedding, so I did it. It seemed to help.
