CHAPTER THIRTEEN

BRAKES

This chapter includes repair and replacement procedures for all brake system components.

Refer to Table 1 and Table 2 located at the end of this chapter.

BRAKE SERVICE

WARNING

Do not use brake fluid labeled DOT 5.1. This is a glycol-based fluid that is not compatible with silicone-based DOT 5. DOTS brake fluid is purple while DOT 5.1 is amber/dear. Do not mix these two different types of brake fluid.

It will lead to brake component damage and possible brake failure.

WARNING

Do not mix DOT 3. DOT 4. or DOT 5.1 brake fluid's because they are not silicone-based. Using nonsilicone brake fluid in these models can cause brake failure.

WARNING

When working on the brake system, do not inhale brake dust. It might contain asbestos, which is a known carcinogen. Do not use compressed air to blow off brake dust. Use an aerosol brake cleaner. Wear a facemask

and wash thoroughly after completing the work.

The disc brake system transmits hydraulic pressure from the master cylinders to the brake calipers. This pressure is transmitted from the caliper(s) to the brake pads, which grip both sides of the brake disc(s) and slow the motorcycle. As the pads wear, the pistons move out of the caliper bores to compensate automatically. As this occurs, the fluid level in the master cylinder reservoir goes down. Compensate for this by occasionally adding fluid.

The proper operation of this system depends on a supply of clean brake fluid (DOT 5) and a clean work environment when performing any service. Any particle of debris that enters the system can damage the components and cause poor brake performance.

Brake fluid is hygroscopic (easily absorbs moisture), and moisture in the system reduces brake performance. Purchase brake fluid in small containers and properly discard small quantities that remain. Small quantities of fluid will quickly absorb the moisture in the container. Only use fluid clcarly marked DOT 5. If possible, use the same brand of fluid Do not replace the fluid with a nonsiliconc fluid. It is not possible to remove all of the old fluid. Other types arc not compatible with DOT 5. Do not reuse drained fluid. Discard old fluid properly. Do not combine brake fluid with fluids for recycling.
