Checking the level and topping up the brake fluid in the hydraulic reservoir of the brake system Volkswagen Polo 2001 - 2009

Parts and consumables:

• Brake fluid DOT-4
• rags

Note:

We recommend checking the level before each ride and topping up the reservoir if necessary. If the brake fluid reservoir has to be topped up quite often, repair the problem immediately. When changing the brake fluid in the system, remember or write down the brand of fluid that was filled in so that when topping up, use the fluid of the same brand.

Checking the level and topping up the brake fluid for vehicles with automatic transmission is similar.

Take precautions when handling brake fluid: it is toxic.

The reservoir is installed directly on the main brake cylinder on the left side of the engine compartment near the bulkhead. It simultaneously serves as a supply tank for the master cylinder of the hydraulic clutch release for vehicles with a manual transmission and is connected to the cylinder by a flexible hose.

Control the level of the working fluid visually. The translucent wall of the tank body is labeled "MAX". The function of the “MIN” mark is performed by the connecting seam of the halves of the tank.

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 with brake fluid on wires, plastic or painted parts of the body can cause damage. 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 at least the “MIN” mark (the connecting seam of the halves of the tank).

2. If the fluid level is below the “MIN” mark, unscrew the reservoir cap and add brake fluid to the “MAX” mark.

Note:

A gradual drop in the brake fluid level with no leaks most likely indicates the need to replace the brake pads.
