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

-- Use the hose from the :VAS5234  to extract as much brake fluid as possible.

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

Observe the Operating Instructions for :VAS5234  !

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

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

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

-- Attach the :VAS5519  .

-- Connect collector bottle breather hose -1- to left front bleeder valve. Then open the bleeder valve and allow the corresponding quantity to flow out (see table). Close the bleeder valve. Torque. Refer to OVERVIEW - FRONT BRAKE CALIPER .

-- Install the cap on the left front brake caliper bleeder valve.

Repeat the same procedure on the right front side of the vehicle.

-- Remove both rear wheels to access the breather valve.

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

-- Attach the :VAS5519  .

-- Connect the collector bottle breather hose -1- to the left rear bleeder valve.

-- Open the bleeder valve and let the corresponding brake fluid capacity flow out. Close the bleeder valve. Torque. Refer to OVERVIEW - REAR BRAKE CALIPER .

-- Install the cap on the left rear brake caliper bleed valve.

-- Repeat the same procedure on the right rear side of the vehicle.

For Manual Transmission Vehicles

Remove The Air Filter Housing. 

Procedure: 

-- Refer to AIR FILTER HOUSING, REMOVING AND INSTALLING [DDSB, DDSA] .
