The Brake Disc is an important component of disc brake system which is fitted for Chevrolet Trailblazer vehicles and is used to surface against which the brake pads are squeezed in order to slow down or stop the car. The rotor is attached to the axle or hub and share its on spinning movement with the wheel, in the case of application of the brakes the hydraulic pressure is used in the calipers to clamp the pads on each side of the rotor. Since the production of Chevrolet Trailblazer models, Brake Discs manufactured have been of different types such as solid and vented. Blade with cooling fins is better than that of solid, common in non sports cars or compact cars. Regular usage of the rotors is important since rotors can develop problems such as warping, scoring or rusting that will impair the stopping power of the vehicle. It is crucial to implement routine maintenance check on the vehicle and replacement of its Brake Disc as often as necessary especially in the Chevrolet Trailblazer.
