NOTICE
DOT 4 brake fluid will damage painted and body panel surfaces it comes in contact with. Always use caution and protect surfaces from spills whenever brake work is performed. Failure to comply can result in cosmetic damage. (00239c)
Cover nearby motorcycle surfaces with a polyethylene protective sheet
to help protect against damage to finish caused by spillage of DOT 4
brake fluid.
If DOT 4 brake fluid contacts painted surfaces, IMMEDIATELY flush area with clear water.
| 1. | Clean the front brake master cylinder cover and the surrounding area. Remove and discard the original cover, gasket and screws. NOTE The brake system on this vehicle uses DOT 4 BRAKE FLUID. Do not mix grades of brake fluid as they are not compatible. Mixing different types of fluid may adversely affect braking ability and lead to brake failure which could result in death or serious injury. | |
| WARNING Contact with DOT 4 brake fluid can have serious health effects. Failure to wear proper skin and eye protection could result in death or serious injury.

| 2. | Fill reservoir with DOT 4 brake fluid. Do not reuse old brake fluid. Use only DOT 4 fluid from a sealed container. | |
| WARNING Be sure the master cylinder relief port is not plugged. A plugged relief port can cause brake drag or lockup and loss of vehicle control, which could result in death or serious injury. (00317a) | ||
| 3. | Verify proper operation of the master cylinder relief port by actuating the brake pedal or lever. A slight spurt of fluid will break the fluid surface in the reservoir if internal components are working properly. NOTE Before installing the master cylinder cover, verify that the cover gasket bellows is not expanded. If bellows is expanded, brake fluid is ejected from the reservoir during cover installation, which could damage the vehicle finish. | |
| 4. | See Figure 1. One end of the master cylinder cover is thinner than the other. Install the cover (with gasket compressed) on the master cylinder reservoir. Position the thinner end above the brake line fitting. Fasten the cover and gasket to the reservoir with the two captive Phillips-head screws. Tighten the screws to 0.8–1.2 N·m (7–11 in-lbs). |
