• Q: How to replace the front brake calipers on 2008 Chevrolet HHR?

  A: Start by checking the brake master cylinder reservoir fluid level when replacing the front brake caliper. Brake fluid needs to be removed to the midway point when the fluid level sits above the halfway point between maximum-full and minimum allowable levels. Begin by elevating the vehicle while support is provided. After that proceed by taking off the tire assembly along with wheel. Apply two wheel nuts tightly to different wheel studs to maintain rotor attachment to the hub structure. Apply pressure to the brake caliper body with a large c-clamp that rests against the caliper back and outer pad until the caliper piston can move past the rotor. After removing the c-clamp apply these steps in order: retract the brake hose fitting bolt followed by removal of the brake hose fitting gaskets and brake hose from the brake caliper then clamp the brake hose inlet port openings to stop fluid leakage and contamination. You need to eliminate the gaskets before taking out the brake caliper guide pin bolts and the brake caliper from its caliper bracket. Examine the guide pins inside the brake caliper while checking the boots for any movement limitations along with.reloaddata or damage from seized pins or torn boots. Replace any faulty components. When installing the new caliper position it on the Brake Caliper Bracket and fasten guide pin bolts at 35 n.m (26 lb ft). Mount the brake hose fitting bolt together with gaskets to the brake hose before installing the brake hose assembly on the brake caliper while tightening the bolt to 40 n.m (30 lb ft). Start by bleeding the hydraulic brake system and following by removing the wheel nuts from the brake rotor-wheel hub to install a new tire and wheel assembly. Apply the Brake Pedal 2/3rds of its travel distance while the engine is off then slowly release the pedal until a firm Brake Pedal feel is achieved to ensure brake caliper pistons and pads are correctly seated.
