How to inspect the Brake Disc?

To inspect the brakes, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and install the lug nuts to hold the disc in place. Then, remove the caliper and bracket as a unit, without disconnecting the brake hose, and suspend it out of the way. Visually inspect the disc surface for score marks and damage, checking both sides. If there is pulsating during brake application, suspect disc runout. To check runout, secure the disc to the hub with lug nuts and place a dial indicator about 1/2 inch from the outer edge of the disc. The reading should not exceed the specified runout limit. If it does, the disc needs refinishing. Ensure the disc is not machined below the minimum thickness, which is cast or stamped into the disc. Use a micrometer to check the thickness. For removal, mark the disc in relation to the hub and remove it. If there are wave washers, cut them off. If the disc is stuck, use a mallet and penetrating oil. Clean the inner opening of the disc and the hub area before reinstalling the disc. Align the mark made and install the caliper mounting bracket and caliper. Then, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts. Depress the brake pedal to bring the brake pads into contact with the disc. Bleeding is only necessary if the brake hose was disconnected. Finally, check the brake operation before driving the vehicle.

Chevrolet HHR Brake Disc

The Brake Disc in Chevrolet HHR vehicles is a part of disc brake system that is required to provide the frictional surface for brake pads to help in halting of the car. Differential to the axle or hub, and rotates with the wheel, and in the event of applying brakes, hydraulic pressure purposes the caliper to squish the pads against the rotor. This design makes it easier to dissipate heat depending on the type of rotors used, where the open vented types have cooling fins. Chevrolet HHR has different models in which they use different types of rotors; these are the solid and the vented rotors. Drum Brake Discs are standard on small cars, non-premium cars, while vented rotos improve heat transfer and are hence on high-performance cars. Most rotors are made from cast iron with the exception being that they may contain some materiel composite. It is very important to inspect the rotors regularly, because they can get worn, scored or warped and need to be replaced in order to yield good braking function.

Each OEM Chevrolet HHR Brake Disc we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
