VW T3 Bus Transporter Conversion to Porsche Brake System Brake Caliper Adapter Wheel Bearing

  • ✓ 312x28 WD00604 Mercedes S-Class brake disc
  • ✓ 4-piston 996351426 / 996351425 Porsche Boxer S brake caliper
  • ✓ front axle

Brake caliper adapter for conversion to the front 4-piston Porsche Boxter S brake caliper, combined with the der 312x28er brake discs from Mercedes .
With this brake conservion to Porsche brake system, the wheel hubs are supplied, which maintain the standard VW pitch circle diameter (PCD) and are identical.

Advantages of this brake system are the perfect deceleration values.

Rims: at least 16 inch.

Required components:

  • brake caliper: Porsche Boxter S, reference 996.351.426 + 996.351.425
  • brake disc: Mercedes S-Klasse 312x28 , reference WD00604

Advantages of this brake system:

  • high deceleration, also in conjunction with our rear axle braking system
  • thanks to the material certificate supplied with the order, it is possible to register your purchase even for series vehicles
  • directly fit to the above-mentioned models and therefore can always be restored to the original state without any problems
  • Our EPYTEC brake caliper adapters do not require any sending of your serial parts, no welding, milling or drilling

Note:

Only suitable for all VW T3 from 1986 onwards. If your model year is before 1986, we recommend simply converting to the newer axle from 1986 onwards. The conversion is very simple, as the axles only differ in the brake caliper mount.

Delivery:

  • 2x brake caliper adapters (see picture)
  • 2x wheel hubs
  • 2x wheel bearings for the front axle
  • high strength mounting screws
  • material certificate
  • Stress analysis / FEM calculation for entry

Tipps, Infos und Hinweise:

  • Zur besseren Belüftung der Bremsanlage empfehlen wir die Ankerbleche/Bremsstaubbleche zu entfernen.
  • Für eine einfache Montage der Felge, empfehlen wir, zwei unserer Radmontagehilfen gleich mit zukaufen >>hier gehts direkt zum Artikel<<
  • Welche Felgengröße du nach deinem Bremsenumbau fahren kannst, können wir pauschal nicht beantworten. Es gibt einfach zu viele unterschiedliche Felgen. Es kann in seltenen Fällen vorkommen, dass die Felgen am Bremssattel minimal anliegt, dann können einfach Spurverbreiterungen verwendet werden. >> Jetzt direkt zu Spurverbreiterungen nach Wunsch <<
  • Den Adapter mit den benötigten Komponenten zu verbauen um anschließend zu prüfen, ob ggf. neue Bremsleitungen benötigt werden, da es je nach Modell sein kann, das die alten nicht lang genug sind, oder vom Anschluss her nicht passen. Wir empfehlen durch den deutlich besseren Wirkungsgrad auf Stahlflexleitugen zu wechseln, eigens für diese Funktionsweise haben wir dafür einen Stahlflexkonfigurator entwickelt, indem du diese nach deinen Wünschen zusammenstellen und anschließend verlegen kannst. Hier geht’s zum Stahlflexkonfigurator >> Stahlflex-Bremsleitung konfigurieren <<

Item as described, many thanks!

  • Can I also use other brake discs as specified in the required components?
  • No, unfortunately that is not possible. The reason is simply: all brake calipers have different heights and depths. If another brake disc is installed, the brake caliper would either not fit on the adapter or not run in the middle of the brake disc. But if you want to install a different brake caliper, we also have an option for you. You can have a custom-made product made for you, take a look at the following link for more information: https://epytec.de/uk/custom-made-products/brake-technology/adapters-for-brake-systems
