My new brakes squeek when i aply them

Unfortunately, this is characteristic of todays metallic and semi metallic pads, particularly if they become glazed. This condition can however be lessened or eliminated by applying a brake silicone lubricant to the back side of the pads, between the pad and the caliper. This will reduce "brake chatter", that is associated with disc brakes. Good Luck! I hope you find this to be very helpful!

2002 gmc 2500hd 4wd abs problems

the problem is most likely a wheel speed sensor at one of the front wheels. retrieving a code in the abs system could pinpoint which wheel it is. i believe the wheel speed sensor is part of the bolt on front wheel bearing assy. if you plan on doing this yourself and are mechanically inclined. you will need an a/c volt meter to check sensors. let me know if i can assist further.
