Alternator replacement, what you need to know
Squealing If you often hear a noise from the vicinity of your car's brakes even when you are not braking, the most common cause is worn brake pads. When this happens, you should take your car to a reputable service for a thorough brake system inspection. If you hear a louder squeal than usual whenever you apply the brakes, your brake linings have probably crystallized, and their function is possibly impaired. Again this is a scenario that requires a thorough examination at the soonest possible time. Grinding When you hear a grinding sound from your brakes when you hit them or even when you are simply driving, there is likely a serious problem with your brakes or with your wheels.
