The fluid level in the reservoir is monitored by a float sensor. If the level drops below the "MIN" mark, the brake fluid emergency level drop indicator light comes on in the instrument cluster.
USEFUL TIPS: Brake fluid type - not lower than D0T-4. We recommend checking the level before each trip and adding fluid to the reservoir if necessary. If you have to add brake fluid to the reservoir quite often, find (see "Checking the tightness of the hydraulic drive of the brake system") and troubleshoot (see section. "Brake system").
When replacing the brake fluid in the system, remember or write down the brand of fluid that will be added so that you can use the same brand of fluid when topping up.
The reservoir is installed on the brake master cylinder on the left side of the engine compartment, near the front shield.
WARNING: Use caution when handling brake fluid, it is toxic.
USEFUL TIPS: In order to avoid unexpected expenses in the future for repairing the brake system, or even the entire car, replace the brake fluid with fresh fluid in a timely manner. It is very hygroscopic and absorbs moisture from the air, which, in addition to causing corrosion of brake system parts, lowers the boiling point of the fluid itself, and this can lead to brake failure during frequent intensive braking.
Do not reuse the fluid drained from the system: it is contaminated, saturated with air and moisture.
If brake fluid gets on wires, plastic or painted body parts, it can cause damage, so always use clean rags when pouring. If liquid gets on these parts, wipe them off immediately with a clean cloth.
1. Check the brake fluid level in the reservoir. It should be between the "MIN" and "MAX" marks on the reservoir body.
2. If the fluid level is below the "MIN" mark, unscrew the tank cap and remove it.
WARNING: A gradual decrease in the brake fluid level without any leaks most likely indicates that the brake pads need to be replaced. Check the condition of the brake pads (see "Checking the degree of wear of brake pads, discs and drums"). Failure to replace brake pads in a timely manner leads to costly repairs (replacement of brake discs, calipers, brake drums)!
3. Add brake fluid up to the "MAX" mark.
4. Screw the cap back on the tank and wipe off any spilled liquid with a clean cloth.
