  Q: How to replace the rear brake disc on Chevrolet HHR?

  A:

  With the vehicle raised you need to take out the tire and wheel before beginning work. Apply a large c-clamp across the caliper body unless you compress the internal components by more than 0.039 inch (1 mm). Touch the ends of the clamp to the caliper's back and Brake Pad on the outer edge. When the c-clamp is tightened to push the piston into the caliper, remove it and detach the Brake Caliper Bracket bolts. Use strong mechanic wire to hold the brake caliper in place to avoid breaking the hydraulic flexible brake hose during work. Move the brake caliper unit off along with its mounts. Also get rid of Brake Disc retainers if present and remember disc position on the Wheel Hub prior to removal. Use the j 42450-a to clean the hub/axle flange while using j 41013 to clean the Brake Disc and make sure no debris stays on the joint surfaces. Place the Brake Disc on its pre-marked position on the Wheel Hub. Then take off the temporary support part and rest the brake caliper assembly onto the wheel knuckle. Fasten the Brake Caliper Bracket bolts at 115 nm torque. Reinstall the tire and wheel together and perform disc and pad surface conditioning steps when relevant replacement occurred.

  Q: How to replace the front brake disc on Chevrolet HHR?

  A:

  You need to lift your vehicle while supporting it followed by removing the wheel and tire set. After removing the brake caliper bracket bolts use heavy mechanic wire to suspend the brake caliper above the hydraulic flexible brake hose. Next step is to take off the brake caliper with its bracket as well as get rid of the Brake Disc retainers when they are present. Before discarding the Brake Disc validate its position next to the Wheel Hub with a marking method. Use parts (J 42450-A) to clean rust and debris from hub/axle surface and (J 41013) to clean the Brake Disc. Look for dirt on each mating surface before placing the Brake Disc in position and lining it up with the Wheel Hub according to the marks. Position the brake caliper and bracket assembly on the wheel knuckle after removing its support and bolt the bracket to the wheel knuckle with torque values of 115 nm (85 lb ft) for j41/jm4 or 130 nm (96 lb ft) for jl9. Reassemble the tire and wheel afterward to end the process while carrying out pad and disc burnishing when applicable.
