Brake Caliper Adapter VW T3 Bus Conversion Porsche Brake System

  • ✓ 312x28 2204210912 Mercedes S-Class brake disc
  • ✓ 4-piston 996351426 996351425 Porsche Boxer S brake caliper
  • ✓ front axle

Brake caliper adapter, VW T3 Bus to convert to front 4-piston Porsche Boxter brake caliper, combined with the 312x28mm Mercedes brake disc. Our adapter kit works with or without ABS.

Furthermore, the price-performance ratio of the Porsche calipers, as well as the Mercedes discs (the pair allready from 130 € from Zimmerman) is right.

Required components:

  • special wheel hubs, front axle (EPYTEC item number 341). A complete kit is available in our shop, item number 276
  • rims: at least 16 inch
  • brake caliper: Porsche Boxter , reference 996.351.426 + 996.351.425 (only 100% suitable for the mentioned Porsche calipers)
  • brake disc: Mercedes S-Klasse 312x28 , reference 220 421 09 12
  • rims: at least 16 inch

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

Delivery:

  • 2x brake caliper adapters (see pictures)
  • high-strength mounting screws
  • material certificate
  • Stress analysis / FEM calculation for entry

Tips, information and advice:

  • To improve ventilation of the brake system, we recommend removing the anchor plates/brake dust plates.
  • For easy mounting of the rim, we recommend purchasing two of our wheel mounting aids at the same time >>go directly to the article here<<
  • We cannot give you a generalised answer as to which rim size you can ride after your brake conversion. There are simply too many different wheel rims. For this reason, we have developed a template with which you can easily check whether the brake system kit fits under your rim. We have included a link to the template in the description. If your rim does not fit, you can simply use wheel spacers. >> Go directly to customised wheel spacers <<
  • Install the adapter with the required components and then check whether new brake lines are required, as the old ones may not be long enough or the connection may not fit, depending on the model. Due to the significantly better efficiency, we recommend switching to steel braided lines. We have developed a steel braided line configurator especially for this function, which you can use to assemble and then install them according to your requirements. Click here for the steel flex configurator >> Configure steel flex brake line <<
  • The handbrake cable must always be used from the installed calliper, which means that the new handbrake cable may have to be adjusted slightly. For conversions in which the original calliper is still used and the original handbrake cable can be used, you may have to route it more directly to compensate for the larger disc diameter and longer travel

Please note that our articles have been designed for racing and motorsport. Use in public road traffic usually requires an individual approval in accordance with § 21 StVZO by an officially recognised expert. Further information can be found under TÜV Süd. For the individual approval, we will provide you with an expert opinion or material certificate, if available.

Ich gebe 5 Sterne. Ich komme aus Dänemark und verwende Google Translate, da mein Deutsch nicht sehr gut ist. Ich habe die falschen Teile für mein Auto vorne und hinten bestellt, war selbst schuld und habe glücklicherweise an epytec geschrieben, weil mir die Dokumentation (Tüv) fehlte und dann wurde mir klar, dass es sich um einen T3 ohne Syncro handelte, den ich bestellt hatte. Also bot mir epytec an, dass ich es zurückschicken könnte und dann mein Geld zurückbekomme, ich habe nun das Geld erhalten und kann dann das Richtige bestellen. Ich kann epytec auf jeden Fall weiterempfehlen. Herzliche Grüße, Martin

  • 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
