Master cylinder
The design of the master cylinder is designed for use in a brake system with a diagonal separation of circuits. In the first circuit, which serves the brake mechanisms of the front wheel and the diagonally opposite rear wheel, the liquid is pumped by a piston connected to the pusher. In another circuit serving the second front wheel and the opposite rear wheel, the fluid is pumped by a floating piston. The master cylinder in question performs the functions of a conventional two-section master cylinder, as well as an indicator of a low brake fluid level.
Note: It is not allowed to blow the parts of the brake system with compressed air containing oil, because this may damage parts made of rubber.
- Replace with new all components for which there is a replacement in the repair kit designed to service the master cylinder.
- Lubricate all rubber parts with clean brake fluid to facilitate reassembly.
- If any hydraulic element was removed or disconnected during the repair, it may be necessary to bleed the brake system completely or partially. See Part 4A. Hydraulic brakes.
- The tightening torques for threaded connections are for dry, unlubricated fasteners.
- All maintenance operations must be carried out on a clean table, not contaminated with mineral oil.
Liquid level sensor
The master cylinder reservoir is equipped with a brake fluid level sensor. This sensor turns on the BRAKE warning light when the brake fluid level is low. The BRAKE indicator lamp also comes on when the parking brake is applied and, in order to check the lamp itself, when the ignition switch is turned to the position "ON" and idle engine. Diagnosis of the BRAKE warning lamp is covered in Parts 4A, "Hydraulic brake system".
