This is the best solution combined with our TMN Good Brake ™️ disc brake kits to bring your braking the current world with power and feel on your Split window or early Bay Window Kombi.

We recommend the use of a disc brake master cylinder to power this indirect servo and we have found that the most commonly used Kombi Servo Master Cylinder works well with it part number 211 611 021AA or 211 611 021AAGR.

You will also need the approbate brake reservoir and blanking port bungs for the master cylinder.

Notes:

Please note that the 2 inlet and 2 outlets, these are NOT METRIC.

They are 3/8 24 SAE. If you wind in an incorrect Male union you will damage the thread and almost certainly leak.

We will not replace the servo if this happens.

The expensive unit will be scrap so be very careful.

We are trying to supply these fittings with every unit to prevent this from happening but it only takes the fitter to loose one and pick up a metric item be sure who ever installs this part understands this.

Secondly, the 3/8″24 SAE Male Unions need to be Long not the standard size most commonly used throughout most vehicles.

The best place to mount these is on the chassis rail behind the beam in front of the front cross member.

This is best installed by an experienced mechanic that has an understanding of vehicle braking systems.

Requires vacuum from the engine intake system or a seperate vacuum pump.
