Brake Lines, Repairing
Special tools and workshop equipment required
- Brake Line Tool Kit: VAS6056
Flare the brake lines using the : VAS6056 without damaging the coating. This allows for partial sections of the brake lines to be inexpensively replaced in certain cases.
- Brake lines must not be bent more than a maximum of 90°, otherwise they kink or deform, which causes an unacceptable constriction in the line.
- Disconnect the brake lines preferably at the underbody.
- The position of intermediate pieces should be selected so that they cannot rub against moving parts.
- Do not lubricate the spindle, clean only with mineral spirits.

Clamp Jaw Assembly Instructions:
- Brake Line Tool Kit - Clamp Jaws -VAS6056/6- (dark) for black brake lines
- Brake Line Tool Kit - Clamp Jaws - VAS6056/7 (light) for green brake lines
- The arrow on the rounded side of the flaring jaws must point toward the edge of the housing.
- The straight side of the clamp jaws must be installed toward the spindle, otherwise the flanged head will not be formed correctly.
Instructions
-- Remove the affected brake line from the brake caliper. While doing so, collect the escaping brake fluid and dispose of it correctly.
-- Cut the brake line at a suitable location (straight, accessible part) with the pipe cutter -2-.
-- Remove the piece to be exchanged.
-- Grease the brake line surface.
-- Clamp the brake line in locking pliers -4- so that 50 mm of the plastic clamping jaws show.
-- Clamp the scraping tool -3- in a drill and position it on the brake line.
-- Remove the coating from the brake line at a slow drill speed and with light pressure against the brake line.
The length of the sheared-off portion is determined by the stop in the shearing tool.
-- Remove the scraping tool from the brake line and remove the shavings.
-- Remove the locking pliers and slide the union bolt -D- onto the brake line.
-- Push the brake line -B- against the stop -A- in the flanging tool.
- The brake line must contact the stop when tightening the hex socket bolts, otherwise the flanged head will not be formed correctly.
C - Long Reach Special Wrench
-- Pretension the brake line in the flanging tool until the brake line can no longer be moved. Fold the stop -A- upward and tighten the hex socket bolts diagonally with the long reach special wrench.
-- Turn the spindle all the way into the flanging tool.
-- Turn the spindle back.
-- Loosen the hex socket bolts diagonally.
-- Remove the brake line from the flanging tool, clean and check the brake line and the flared head.
-- Briefly rinse the part of the brake line still in the vehicle by connecting the : VAS6860 .
-- 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 new brake line to be inserted with compressed air.
-- Join the brake lines with the connecting piece -E-.
-- Assemble the brake line.
-- Then bleed the brake system. Refer to HYDRAULIC SYSTEM, BLEEDING .
