Helpful Hints: A fluid level sensor is installed in the reservoir of the master brake cylinder, a signal lamp in the instrument cluster warns the driver of an emergency drop in the fluid level. Nevertheless, we recommend that you periodically visually check the level directly from the marks on the tank wall. When the level drops to the mark «MIN» it is necessary to add liquid to the tank. If you have to add brake fluid to the reservoir quite often, find (see «Checking the tightness of the hydraulic drive of the brakes») and troubleshoot.
When changing the brake fluid in the system, remember or write down the brand of fluid that will be filled in so that you use the same brand when topping up.
The reservoir is installed on the main brake cylinder on the left side of the engine compartment near the bulkhead.
Warning: Be careful when handling brake fluid, it is toxic.
Useful tips: In order not to expose yourself to unforeseen expenses for the repair of the brake system, and even the entire car as a whole, in the future, replace the brake fluid with fresh one in a timely manner. It is very hygroscopic and absorbs moisture from the air, which, in addition to corroding parts of the brake system, lowers the boiling point of the fluid itself, and this can lead to brake failure during frequent heavy braking. Do not reuse the fluid drained from the system: it is contaminated, saturated with air and moisture.
Contact of brake fluid on wires, plastic or painted body parts can cause damage, so always use clean rags when filling. If liquid comes into contact with these parts, wipe them off immediately with a clean cloth.
1. Check the brake fluid level in the reservoir. It must be between the marks «MIN» And «MAX», applied to the body of the tank.
2. If the fluid level is below the mark «MIN», unscrew the tank cap and remove it.
Warning: A gradual drop in the brake fluid level with no leaks most likely indicates the need to replace the brake pads. Check the condition of the brake pads (see «Checking the degree of wear of brake pads and discs»). Late pad replacement leads to costly repairs (replacement of brake discs, calipers).
Pay special attention to the condition of the clutch master and slave cylinders. They can also cause a decrease in the level of brake fluid in the reservoir.
3. Add brake fluid to the mark «MAX».
4. Wrap the tank cap, wipe the spilled liquid with a clean cloth.
