Brake Fluid Reservoir
BRAKE MASTER CYLINDER RESERVOIR
Purpose
The brake master cylinder reservoir and cover used on these models are made of plastic. The cover snaps onto the top of the brake master cylinder
reservoir. A seal located between the cover and brake master cylinder reservoir to keep contaminants out of the brake fluid.
Operation
The brake master cylinder reservoir must be kept properly filled. This ensures adequate reserve fluid for braking pressure, make-up fluid for brake
lining wear and prevents air from entering into the hydraulic system. Brake fluid expansion is due to the heat absorbed from the brakes and engine
compartment as the temperature increases. The brake master cylinder reservoir should not be overfilled. See: Service and Repair
