• Q: How to replace the wheel cylinder on 2008 Chevrolet HHR?

  A: Start the Wheel Cylinder replacement process by raising and supporting your vehicle. Start by extracting the tire with attached wheel followed by the Brake Drum's removal. First clean debris from around the Wheel Cylinder before removing the bleeder cap and valve to disconnect the brake pipe fitting from the Wheel Cylinder. You must cap the exposed brake pipe end to stop fluid loss and protect the brake cylinder from contaminants. Start by removing all mounting bolts which secure the Wheel Cylinder to its position. First use the j 38400 Brake Shoe spanner and spring remover (J 38400) to open the brake shoes at their top ends before extracting the Wheel Cylinder from the Brake Backing Plate. Use the j 38400 tool (J 38400) to open brake shoes at their top while installing the new Wheel Cylinder onto the Brake Backing Plate. Secure the Wheel Cylinder mounting bolts with torque to 16 n.m (12 lb ft). Place the brake pipe end cap aside before fitting the brake pipe connection at the Wheel Cylinder and torquing it to 21 n.m (15 lb ft). Tighten the Wheel Cylinder bleeder valve to 8 n.m (71 lb in) torque. The installation process involves first fitting the Brake Drum followed by bleeding the hydraulic brake system while finishing with bleeder valve cap installation. To finish up follow these steps: adjust the drum brakes and install the tire/wheel assembly before lowering the vehicle.
