Your Chevrolet Trailblazer brake pads are an essential component of your vehicle’s disc braking system. You will find a pair of Trailblazer brake pads mounted on top of each of your calipers, on either side of your brake rotors. Brake pads are composed of a metal backing plate that is attached to a thick frictional lining with either glue or rivets.

Each time you engage your brakes, the calipers act as small hydraulic clamps to bring your Chevrolet Trailblazer brake pads into contact with the rapidly spinning metal disc of your brake rotors. Friction is generated between these two components, which is used to halt the rotating motion of your wheels and bring your vehicle to a stop.

Since these mechanisms operate through friction, there is bound to be some wear happening. The lining of your Trailblazer brake pads gradually erodes through use, and it is important to change them when the thickness of the lining drops to a certain point. There are two ways to check the lining of your Chevrolet Trailblazer brake pads. The most obvious and most often overlooked way is audibly. Your Trailblazer brake pads are designed to emit a high-pitched squeaking or squealing noise when the lining is worn to below a quarter of an inch. Since this noise does not affect the function of your brakes, many drivers ignore it. Eventually, if it is ignored long enough, the squeaking noise will become a grinding sound, which means that your lining is completely worn and your brake rotors are rubbing against the metal backing plate. You can also visually check your Trailblazer brake pads by looking through the front of your wheels, where you should be able to see them without removing your tires.When you need new brake pads, look no further than our extensive online catalogue.
