How to replace the rear brake disc on 2009 Chevrolet Cobalt?

Start by lifting and stabilizing the vehicle before taking off the tire assembly from the wheel. You should position a very large c-clamp across the brake caliper body so its ends lie on the back of the caliper and outer Brake Pad. Tighten this clamp enough to apply 1 mm compression to the caliper piston (0.039 in) to protect its internal adjustment system. Secure the brake caliper with heavy mechanic wire to prevent strain on the hydraulic flexible brake hose while also maintaining the caliper in position without disconnecting it. Use wire to support the brake caliper assembly on the Steering Knuckle as you remove it from the Steering Knuckle with precise wheel stud-led disc position marking. Dispose all residue from both hub/axle flange and Brake Disc using the j 42450-a and j 41013 cleaning tools to eliminate all remaining materials from contact areas. Correct the Brake Disc's orientation position by using the matching marks set on the hub/axle flange. Measure the lateral runout (LRO) of the assembled Brake Disc when possible to guarantee optimal performance before performing any corrections on existing measurements that exceed specifications. Install the brake caliper along with the bracket assembly onto the Steering Knuckle and put on your tire and wheel assembly before lowering the vehicle. Disc replacement or pad installation requires pad turning and disc refinement.
