    Q:
    How to replace the brake caliper bracket on the front on Chevrolet Astro? Posted by Customer
    A:
    The best way to work on front brake caliper brackets includes using mechanic wire to stabilize the caliper while keeping the brake hose connected safely. Take off the caliper from the bracket baseplate before you disconnect the hose for installation. After removing the two mounting bolts from the Brake Caliper Bracket take out the bracket while cleaning its interior and underside areas. The new bracket needs to have all remaining adhesive patch removed while you clean bolt threads with denatured alcohol to apply threadlocker gm p/n 12345493 (Canadian P/N 10953488) properly. Secure the two caliper bracket mounting bolts into place at 175 nm (121 lb ft) torque value. Fit the brake pads starting with inner pad-1 and pad-2 wear indicators back in place, and slide them onto the rotor surface. First reattach both anti-rattle clips before proceeding. Set the brake caliper in place then put on the tire and wheel unit while lowering the vehicle. When the engine is off apply the brake pedal gently to around 2/3 of its range and ease up the pressure. Push the brake pedal once every 15 seconds to ensure brake caliper pistons and brake pads reach their final position.
