Checking the level and topping up the brake fluid

            0

You will need: brake fluid, clean rag.

GOOD HINT: The type of brake fluid is DOT-4.


USEFUL ADVICE: We recommend checking the level before each ride and topping up the reservoir if necessary. If you have to add brake fluid to the reservoir quite often, find (cm. «Checking the tightness of the hydraulic drive of the brakes») and troubleshoot (see sect. 9 «Brake system»).


USEFUL ADVICE: 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 brake master cylinder on the left side of the engine compartment near the bulkhead (in the photo, the tank is closed with a grille of the air intake box).

WARNING: Be careful when handling brake fluid, it is toxic.


USEFUL ADVICE: 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.



USEFUL ADVICE: Do not reuse the fluid drained from the system: it is contaminated, saturated with air and moisture.


TIP: If brake fluid comes into contact with wires, plastic or painted parts of the body, they can be damaged, 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 cap of the tank..

WARNING: A gradual decrease in the brake fluid level without leaks most likely indicates the need to replace the brake pads. Check the condition of the brake pads (cm. «Checking the degree of wear of brake pads, discs and drums»). Late pad replacement leads to costly repairs (replacement of brake discs, drums, calipers)!





3.... and add brake fluid to the mark «MAX».

NOTE: The reservoir is in a hard-to-reach place, so you need to use special tools to top up the brake fluid (e.g. syringe and hose) or remove the air intake grille and the water deflector (cm. «Removal and installation of the grille of the air supply box and the drain shield»).




4. Then wrap the tank cap, wipe the spilled liquid with a clean cloth.
