Removal
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.
1. Unscrew the pad retaining pin plug from the caliper.
1. Pad retaining pin plug; 2. Loosen the pad retaining pin.

Warning: Do not allow the calipers to hang on the brake hoses as this may damage the hoses and could lead to loss of motorcycle control and an accident.
3. Slacken and remove the caliper mounting bolts and slide the caliper off the disc.
1. Caliper fixings
4. Remove the pad retaining pin and remove the pads from the caliper. Take care not to lose the pad retainer from the mounting bracket or the anti-rattle spring from the caliper body.

Inspetion
1. Check the pad retainer, anti-rattle spring and retaining pin. Renew any component which shows signs of damage or corrosion.
2. Check the caliper body slides easily on the mounting bracket pins and check there is no sign of leakage from the piston seals. Rectify any problems before installing the pads.
Note: Complete the assembly of the brake pads to one caliper (see assembly for details) before removing the pads from the other caliper.
Installation
Warning: Never use mineral based grease (such as lithium or copper based grease) in any area where contact with the braking system hydraulic seals and dust seals is possible. Mineral based grease will damage the hydraulic seals and dust seals in the calipers and master cylinders. Damage caused by contact with mineral based grease may reduce braking efficiency resulting in an accident.
Caution: Never lever directly against the disc, caliper or the pad lining material as this will damage these components. Always use a levering tool made from a soft material which will not cause damage to the load bearing surfaces. 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.
1. If new pads are being installed, push the pistons fully back into the caliper body. Keep an eye on the fluid level in the reservoir whilst retracting the pistons to prevent fluid spillage.
2. Ensure the pad retainer is correctly fitted to the mounting bracket and the anti-rattle spring is securely clipped onto the caliper body. 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.
3. Lubricate the pad retaining pin with a thin smear of proprietary high temperature copper based grease.
4. Ensure the heat isolation pads are fitted to the back of each brake pad. Fit the pads to the caliper with their friction material surfaces facing each other. Locate the pad upper ends in the mounting bracket retainer then align them with the caliper body and insert the retaining pin.
5. Slide the caliper onto the disc, ensuring the pads pass either side, and fit the mounting bolts. Tighten the mounting bolts to 28 Nm.
6. Tighten the pad retaining pin to 18 Nm.
7. Fit the pad retaiming pin plug to the caliper and tighten to 3 Nm.

8. Pump the brake lever to correctly position the caliper pistons.
9. Repeat the removal, inspection and installation process for the other caliper.
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.
10. Check the front brake fluid level and top up as required with new DOT 4 fluid.
11. Check for correct brake operation. Rectify as necessary.
Warning: lt is dangerous to operate the motorcycle with defective brakes; you must have your authorised Triumph dealer take remedial action before you ride the motorcycle again. Failure to take remedial action may result in reduced braking efficiency leading to loss of motorcycle control and an accident.
