WARNING:

Brake fluid must never come into contact with fluids containing mineral oils (oil, gas, cleaning solutions). Oils containing minerals damage seals and rubber grommets on brake systems.
Brake fluid is poisonous. Do not let brake fluid come in contact with the paint due to is corrosive effects.
Brake fluid is hygroscopic, which means that it absorbs moisture from the air. Always store brake fluid in air-tight containers.
Wash off any spilled brake fluid with plenty of water.
Follow all disposal regulations.

Extract the Brake Fluid

NOTE:

Do not remove the screen inside the brake fluid reservoir.

After extracting, observe that no further brake fluid runs into the reservoir (the brake fluid level in the reservoir must align with the lower edge of the screen).

-- Remove the cap -1- from the brake fluid reservoir.

WARNING:

Do not use extracted brake fluid again!

Bleeding the Brake System

-- Attach the adapter -1- to the brake fluid reservoir.

Pay attention to the device owner's manual. Refer to :VAS5234 Owner's Manual.

-- Set the correct pressure using a :VAS5234 . Refer to BRAKE HYDRAULIC SYSTEM - BLEEDING .

-- Connect the hose on the :VAS5234 to the adapter -1-.

NOTE:

The bleed hose must fit tightly over the bleed screw to prevent air from getting into the brake system.

The brake fluid level in the reservoir must be high enough so that air cannot get into the brake system.

For RHD vehicles, begin with the front right.

By using the :VAS6564/9 the removal of the rear wheels is no longer necessary.

Front Axle

-- Remove the cap -1- from the breather valve on the left front brake caliper.

-- Remove the dust cap from the breather valve -arrow-.

-- Connect the bleed hose and connect the pressure hose with the collector bottle.

Use the :VAG1238/B3 if necessary to bleed.

-- Open the breather valve.

-- Allow approximately 100 ml brake fluid to escape.

-- Close the bleeder valve.

-- Push the clutch pedal quickly from stop to stop 10 to 15 times.

-- Open the breather valve.

-- Allow another 50 ml brake fluid to escape.

-- Close the breather valve and install the dust cap.

-- Install the air filter housing in reverse order of removal.
