3. Service
3.1. Regular maintenance
Cleaning your brake
The braking performance will be severely reduced if the disc rotor and pads become
contaminated with oil, brake fluid or after-market degreasing and cleaning agents.
Clean your brake with water.
If the disc rotor becomes contaminated it can be cleaned by wiping with a rag with
isopropyl alcohol or disc brake cleaning products designed specifically for bicycle disc
brakes. Heavily contaminated brake pads will need replacing.
Checking for system leaks
Check the hose for any damage such as chaffing against the bike, or whenever the bike
has been rough handled or dropped. A split hose (however tiny) will cause a system
leak which will severely impair braking performance. A damaged hose will need
replacing.
Check the caliper and lever assemblies for any signs of fluid loss. See the
Troubleshooting section for fixing any problems.
Checking the brake pads
The brake pads will need replacing when the friction material is worn down to 0.5mm.
Do not wait until the friction material has worn through to the backing plate because the
brake will not function and you will damage the disc rotor.
3.2. Changing the brake pads
1. Remove the wheel.
2. Remove the split pins using pliers (and the pad retaining spring on the XC4 caliper)
and slide out the old pads from the caliper.
3. Retract the pistons on the XC4 and Closed 2 brakes by turning the brake lever
master cylinder screw adjuster anti clockwise. For the Open 2 and DH4 brakes
gently prise the pistons back using a plastic tire lever (or similar).
4. Clean the inside of the caliper with a clean rag and insert the new brake pads, (and
retaining spring on the XC4 caliper) and new split pins. The new pads must be
genuine Hope compatible pads for the appropriate caliper.
5. Refit the wheel and adjust the pad position, (see section 2.5).
