Bleeding the hydraulic brake system




A warning

The brake fluid used in the hydraulic system of brakes, is poisonous, so if you hit it on the skin should immediately wash it with plenty of water. If the liquid gets into your eyes or inside the body, you must seek medical advice immediately. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. In addition, the fluid used in the hydraulic system of brakes, dissolves a paint and plastic, therefore at liquid hit on a paint and varnish covering of the car wash it with plenty of water. Also, this fluid is hygroscopic, i.e. absorbs moisture from the air, therefore a liquid, stored long time in open ware, it is not recommended.


Bleeding the hydraulic system of brakes is necessary for removal of air which considerably reduces braking efficiency. The air can get into the hydraulic system owing to system depressurization at repair, replacement of separate knots or a brake liquid. In air presence in a drive specifies the increased brake pedal travel and its softness. Before air removal check up tightness of all knots of a drive of brakes and their connections.

Never use brake fluid again.

When performing the pumping of the brake system does not let the brake fluid level drop below the middle of the tank.

If brake fluid is gone from the system due to a leak in the system, find the cause and repair the leak before proceeding.

If the hydraulic system is disconnected and have been partially taken appropriate precautions to prevent the further loss of fluid can be pumped only part of the system.

Pumping can be performed with an assistant or by yourself, set pumping the brake system. Always act according to instructions. It is recommended to use a set whenever possible, as it greatly simplifies the process of pumping. If set to no bleeding, you should stock up on clean containers and clear plastic tube of appropriate length, which should fit dress for the bleeder valve. This will require the assistance of another person.

The sequence of pumping

If produced only a partial disengagement of the hydraulic brake system and follow the proper precautions, it is enough to pump over only this part of the system. When all is done pumping hydraulic braking systems, pumping each contour begin with the front wheel on models without antilock brake system. On models with anti-lock braking system in the first bleed the front loop.
