REMOVAL
1. Siphon 2/3 of the brake fluid from master cylinder, raise and support vehicle, and remove wheels.
2. Reinstall two wheel nuts to retain rotor, then remove caliper mounting bolts, Fig. 3.

3. Install caliper mounting bolts and torque bolts to 18 ft. lbs.
4. Install brake hose and mounting bolts, using new copper gaskets, then torque bolt to 17 ft. lbs.
5. Refill master cylinder and bleed brake system.
