Brake Lines, Repairing
Special tools and workshop equipment required
- Brake Line Tool Kit: VAS6056
Flare the brake lines using : VAS6056 without damaging coating. In this way, brake lines can be inexpensively partially replaced in certain cases.
Danger of damaging the brake lines.
- Using the Brake Line Kit V.A.G. 1356 is not permitted because of the coating and diameter of the black brake lines.
- Brake lines must not be bent more than a maximum of 90°, otherwise they kink or deform, which causes unacceptable constriction in the line.
Disconnect brake lines preferably at underbody.
Position of intermediate pieces should be selected so that they cannot rub against moving parts.
Do not lubricate spindle, clean only with mineral spirits.

Flaring Jaws Assembly Instructions
- VAS6056/6 (dark) for black brake lines
- VAS6056/7 (light) for green brake lines
The arrow on the rounded side of the flaring jaws must face toward edge of housing and the straight side of the flaring jaws must be installed toward spindle, otherwise flared head will not be formed correctly.
Instructions
-- Remove affected brake line at brake caliper and collect escaping brake fluid and dispose of it correctly.
-- Disconnect brake line at appropriate location (straight, accessible part) with line cutter -2-.
-- Remove the piece to be exchanged.
-- Lubricate brake line surface.
-- Clamp the brake line in self-grip pliers -4- so that 50 mm of the plastic clamping jaws show.
-- Clamp the shearing tool -3- in a drill and place it on the brake line.
-- Shear the coating from the brake line at a slow drill RPM and with light pressure against the line.
The length of the sheared-off portion is determined by the stop in the shearing tool.
-- Remove the shearing tool from the brake line and remove the shearing remains.
-- Remove locking pliers and union bolt -D- from brake line.
-- Slide the brake line -B- against the stop -A- in flaring tool.
Brake line must contact stop when hex socket heat screws are tightened, otherwise the flared head will not be formed correctly.
C - Long reach special wrench
-- Pretension the brake line inside the flaring unit until the brake line can no longer be moved. Fold stop -A- up and tighten hex socket head screws diagonally with long reach special wrench.
-- Turn the spindle to stop in flaring tool.
-- Turn the spindle back.
-- Loosen the hex socket head screws diagonally.
-- Remove the brake line from the flaring tool, clean and check the brake line and the flared head.
-- Quickly rinse the part of the brake line still in the vehicle by connecting the : VAS5234 .
-- Connect the bleeder bottle to the flared head on the brake line and let the : VAS5234 run for a little bit until all of the brake fluid has flowed through.
-- Clean the brake line with compressed air.
-- Join brake lines with connecting piece -E-.
-- Assemble brake line.
-- Then bleed the brake system. Refer to HYDRAULIC SYSTEM, BLEEDING .
