Hydraulic System: Description and Operation
Hydraulic Brake ActuationWARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately.
CAUTION:
^ Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.
^ Blistering or swelling of rubber brake components may indicate contamination of the brake fluid by a petroleum-based substance. Contaminated rubber components in the hydraulic brake system must be replaced and the entire hydraulic brake system must be flushed with clean brake fluid to prevent recontamination.
^ Never use copper tubing. It is subject to fatigue, cracking and corrosion, which could result in brake tube failure.
^ Steel tubing is used throughout the brake hydraulic system. All brake tube fittings must be properly double flared to provide strong leakproof connections. When bending the tubing to fit the underbody or rear axle contours, be careful not to kink or crack the tube.
^ If a section of brake tube is damaged, the entire section must be replaced with a tube of the same type, size, shape and length.
^ When replacing hydraulic brake tubing, hoses or connectors, tighten all connections securely. After replacement, bleed the brake system.
Hydraulic brake actuation consists of the following components:
^ brake pedal and bracket
^ brake master cylinder
^ brake master cylinder reservoir
^ rear load sensor proportioning valve
