Squeak in front end after a break job

[maraxis1985]

I just did my breaks and had the rotors machined on my 98 mustang v6. When i was brining it back form the inspection that it passed there is a squeak comming from the driverside wheelwell. This squeak only happens when the car is in motion and goes away when the break is applied. I took it apart again but I cant see anything that would cause the problem. Could this squeak be beacause i got the rotors machined? do you think this is just something that would go away when the breaks get broken back in? Thanks for the help in advance.

Was there any squeaking noise before you had the rotors turned? It sounds like a wheel bearing issue.Generally when wheel bearings are going bad,if they are making grinding or squeaking noises the noise tends to stop when the brakes are applied.The brake pads act as a load balancing device and holds the wheel/bearing firmly in place.Once released,the noise returns as the bearing is free to slide right out of place again.Now i'm not saying the wheel bearing is bad,just picking the possibilities. Did you replace the calipers or just put pads on?You could have a caliper that's sticking and dragging.Or you could have a squeal caused by using ceramic pads (if you used ceramic).Still,you shouldn't be hearing noises like this without touching the pedal.

If you machined the rotors, did you bed them to break in the pads? The bedding process consists of a number of firm stops from highway speed to slow speed to build heat in the rotors and break in the rotor and pad wear surfaces.

A review of the process is available Here.

Thanks for the information and help with the problem. I slaped the old pads on to see if it would squeak and it didnt. I brought the others back and put some monroes on and so far no squeak.

May I ask what type of pads you returned and what brand name? Were they ceramic? Thanks

they were whatever autobarn pushes cuz it was most expensive. I dont belive they were ceramic. I then got Monroes and they are pretty good. breaks are a bit deep but in time they will be evend out.
