How to inspect the Brake Disc on Chevrolet Cobalt?

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 Cobalt Brake Disc

Brake Disc in reference to Chevrolet Cobalt automobiles refers to a component in the disc brake system with the principal duty of generating the friction required to cause the deceleration of the car. These rotors are usually forged from some kind of gray iron, although the design might also incorporate fins or vanes for the obvious purpose of cooling. In the years of development, many kinds have been used; drilled and slotted rotors increase performance by offering better heat and moisture dissipation but cause more pad wear. Brake Discs need to be well maintained because they may develop problems such as scarring, warping or rusting, all of which will have a negative impact of the braking process. This was why experts have called for consistent check up by motorists and replacement of the brake pads as soon as they become wore out to avoid damaging the rotor. By providing appropriate attention the brake rotor of Chevrolet Cobalt provide effective braking authority thus helping in safety of the vehicle.
