Brakes

Design and specifications

The brake system is structured on two separate contour diagram at the front and rear wheels. The brake mechanism of a disk type with hydraulic self-regulation and the wear pads. Each circuit has its own reservoir on the master cylinder. To increase the effectiveness of the braking system is configured with a vacuum booster (gain - three).

On some cars the last few years the issue was placed anti-lock braking system (ABS).
The parking brake with mechanical (rope) operated drum and acts on the rear wheels, and drums are structured on the rear discs. Clearances pad manually adjusted every 48,000 km.

After carrying out any work related to removing the hydraulic brake lines, or the loss of brake fluid, it is necessary to carry out pumping the brake system.

The final stage of work on the brake system is running (check operation). Brakes should be tested on a large and at low speed.

In the braking system affect the tires, the load of the car (its alignment). The frequency of inspection for leaks every 16,000 km. Replacing the brake fluid once a year.
