Removal
1. Raise and support the rear of the motorcycle.
Warning! Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it from falling and causing injury to the operator or damage to the motorcycle.
2. Release the wheel spindle nut and withdraw the spindle to a point where it clears the caliper carrier.

3. Release the torque reaction bolt from the caliper carrier, collecting the spacer from between the wheel and calliper carrier.

4. If removing the calliper completely, disconnect the brake hose. Otherwise, leave the hose attached.
Warning! Do not allow the caliper to hang on the brake hoses as this may damage the hoses and could lead to reduced brake efficiency causing loss of motorcycle control and an accident.
5. As an assembly, manoeuvre the calliper and carrier until it is clear of the brake disc and wheel, collecting the spacer once it is freed from the caliper carrier.

6. Remove both "R" clips from the pad retaining pin. Then remove the pin.

7. Remove the brake pads and inspect for damage or wear beyond the service limit.
8. Remove the anti-rattle spring and inspect for damage.
Installation
Warning! Never use mineral based grease in any part of the braking system or in any area where contact with the braking system is possible. Mineral based grease will damage the hydraulic seals in the calipers and master cylinders. Damage caused by mineral based grease may reduce braking efficiency resulting in loss of motorcycle control and an accident.
Caution! Brake fluid will be displaced as the caliper pistons are compressed. To prevent body damage, ensure that the displaced fluid does not come into contact with any part of the bodywork or the rear wheel.
1. If fitting new pads, use hand pressure to compress the caliper pistons fully into their bores.
2. Install the anti-rallle spring into the caliper.

3. Renew the brake pads as a pair or, if both pads are in a serviceable condition, clean the pad grooves before fitting them.
Warning! Do not apply more than a minimum coating of grease to the pad retaining pins. Excess grease may contaminate the brake pads, hydraulic seals and discs causing reduced braking efficiency and an accident.
4. Lubricate the pad retaining pin using a minimum amount of proprietary high temperature "Copperslip" type grease. Refit the pin and retain with both "R" clips.
5. Position the spacer between the wheel hub and caliper carrier.

1. Wheel hub; 2. Spacer
6. Position the caliper and carrier over the disc ensuring both pads are correctly aligned either side of the disc.
7. Align the caliper carrier with the wheel spindle, spacer and swinging arm. Once in alignment, push the wheel spindle through the spacer and caliper carrier.
8. Align the caliper carrier to the torque reaction fixing point. Once in alignment, fit the torque reaction bolt.
9. Tighten the wheel spindle nut to 110 Nm and the torque reaction bolt to 69 Nm.

10. If previously disconnected, incorporating new washers to each side of the union, fit and tighten the brake union bolt to 25 Nm.
11. If the brake hose has been disconnected, bleed the rear brake as described on page 15.20.
12. Pump the brake pedal to correctly position the caliper pistons.
Warning!
- Use only DOT 4 specification brake fluid as listed in the general information section of this manual. The use of brake fluids other than those DOT 4 fluids listed in the general information section may reduce the efficiency of the braking system leading to loss of motorcycle control and an accident.
- Observe the brake fluid handling warnings given earlier in this section of the manual.
13. Check the brake fluid level and top-up as required with new DOT 4 fluid.
14. Check the operation of the rear brake. Rectify as necessary.
Warning! It is dangerous to operate the motorcycle with defective brakes and you must have your authorised Triumph Dealer take remedial action before you attempt to ride the motorcycle again. Failure to take remedial action may reduce braking efficiency leading to loss of motorcycle control and an accident.
Rear brake caliper
Note: The seals and pistons of the rear calliper are not serviceable items. Should a fault occur in the caliper, the complete caliper must be renewed.
