Keeping your vehicle's brakes in perfect working order is absolutely essential for safety. If you hear a screeching noise when braking, you may need to replace the brake pads. To do the job right, you also need the right accessories. The brake pads must be properly fitted with the proper clips, pins, springs or bolts that go with your car's make, model and year. Brake pad fitting kits come in rear axle and front axle configurations and are made for ABS systems as well.
