Disc brake caliper – removal and installation
Warning: The dust created by the brake system is harmful to your health. Never blow it out with compressed air and don’t inhale any of it. An approved filtering mask should be worn when working on the brakes. Do not, under any circumstances, use petroleum-based solvents to clean brake parts. Use brake system cleaner only!
Note: This procedure applies to the front and rear disc brake calipers.
Removal
1. Loosen the front or rear wheel lug nuts, raise the front or rear of the vehicle and place it securely on jackstands. Block the wheels at the opposite end. Remove the front or rear wheel.
2. Remove the brake hose-to-caliper banjo bolt and disconnect the brake hose from the caliper (see illustration).
4.2 To disconnect the brake hose, remove the brake hose-to-caliper banjo bolt (front caliper shown)
Discard the old sealing washers. Plug the brake hose immediately to keep contaminants and air out of the brake system and to prevent losing any more brake fluid than is necessary. Note: If you are simply removing the caliper for access to other components, leave the brake hose connected and suspend the caliper with a length of wire – don’t let it hang by the hose (see illustration 3.6e).
3. Remove the caliper mounting bolts and detach the caliper from the mounting bracket (see illustration 3.6b).
Installation
4. Installation is the reverse of removal.
Use new sealing washers on each side of the brake hose fitting and tighten the banjo bolt and the caliper mounting bolts to the torque listed in this Chapter’s Specifications.
5. Bleed the brake system (Brake hydraulic system – bleeding).
Note: If the brake hose was not disconnected, bleeding won’t be required. Make sure there are no leaks from the hose connections. Test the brakes carefully before returning the vehicle to normal service.
