Checking the brake fluid level in the brake system

Regularly check the fluid level in the master cylinder reservoir. If a sharp drop in fluid level is detected, check the tightness of the brake system. The brake fluid level should be opposite the "Max" mark, but not higher. Regularly clean the ventilation hole.

Brake fluid is aggressive and can damage the paintwork of the car body. If brake fluid gets on the painted surfaces of the car body, wash it off immediately with a sponge soaked in water.

If water gets into the brake fluid due to condensation of water vapor, its properties may change when heated and cooled. In addition, this causes corrosion of the working surfaces of the brake pistons and cylinders.

It is recommended to replace the brake fluid with fresh fluid every two years of operation.

Brake fluid level warning light

The brake fluid level indicator lamp comes on when the ignition is turned on and goes out when the engine is running after the handbrake is released.

If the light stays on or if the light comes on while driving, it may mean that the brake fluid level has dropped below the acceptable level or there is a brake fluid leak. Add brake fluid to the reservoir up to the "Max" mark

If the warning light comes on again after pressing the brake pedal several times, you should drive to the nearest service station, taking precautions.

Warning: If the brake fluid level indicator lamp does not light when the ignition is turned on (the contact is broken or the lamp is burnt out), the fault should be corrected immediately.

Front brake pads

Check the thickness of the brake pads every 15,000 km. Do not change brake pads with axles. Replace oily pads. Also replace slightly worn pads with pads that have come loose from the base or with large cracks in the pads.
