Front brake noise - new discs?.

[thatfatbloke]

Been getting a squeal from the n/s/f. when braking or,strangely enough,when turning right but not braking. Took it to the mender man yesterday who immediately noticed a lip on the outside of the disc. He removed the pads and ground them down a bit so they don't touch the lip. He obviously advised new discs for the long term. All seemed fine for about two miles but then the noise started again. The noise disappears above about 20 mph,or when it rains. What I can't work out is how it squeals when turning right,but not braking.

First of all there is always a lip on the outside edge of the discs this is caused by the wearing down of the face of the disc by application of the brakes and the pad taking off the metal over time.

The cause is probably a wheel bearing starting to fail as the sound is present when loading is applied to the bearing,from your description it is the front nearside
