Brake disc adapter on T3 bus model for conversion to T4 brake disc, rear axle.
With these adapters, both T4 brake discs, 280 and 294 , can be mounted with the T4 caliper. Just be careful when buying components: if you want to install, for example, the 280 brake discs, you have to use the original brake calipers and the original brake caliper mounting brackets for the 280 brake discs.
Advantages:
- top deceleration compared to the undersized original brake system
- the system no longer warms up and no more fading
- thanks to the material certificate supplied with the order, it is possible to register your purchase
- quick and easy assembly with the supplied mounting screws
- Completely new wheel hubs with wheel bolts included

Tips, information and hints:
- For a better ventilation of the brake system, we recommend removing the dust cover plates and brake anchor plates.
- We can not answer generally, which rim size you can mount after your brake conversion. There are simply too many different rims.
- In rare cases it is possible that the rims touch minimal the brake caliper, then you can simply use spacers.
>> Now directly to spacers << - Install the adapter with the necessary components and then check if new brake lines are required. Because, depending on the vehicle, the lines may be too short or the line tips may not suitable. We advise you to change to steel braided brake line because of the quality and technical advantage. Specifically for this, we have developed an online brake line configurator, where you can assemble the type of steel braided brake lines you want.
Click here to go to the >> configure steel braided brake lines << - Always use the hand brake cable of the installed brake caliper. So sometimes you have to modify / adapt the new handbrake cable. For conversions, where the original caliper is used and the handbrake cable can be used, you may need to pull the cable without any other fittings (ie directly) to compensate for the long distance due to the large diameter of the large brake discs.

Estoy poniendo esta calificación esperando cambiarla pronto ya que mi pedido no ha llegado a mi domicilio, al parecer hay un problema con la paquetería, yo vivo en México y en mi país no hay adaptadores para frenos traseros , algunos entusiastas usan sistemas de frenado de otros autos, pero con adaptaciones hechas de manera casera por decirlo de alguna manera, yo sigo a algunos dueños de VW Vanagon en Instagram y vi que usan los adaptadores de Epytec y me gustó mucho el producto. Ello me llevo a comprar en la tienda en línea, espero pronto lleguen las piezas y pueda instalarlas en mi Vanagon 1986, seguro esteré muy contento al recibirlas y probarlas, los adaptadores se ven muy bien fabricados en las fotos publicadas en redes sociales, seguramente la calidad de los materiales y la mano de obra son excepcionales.
- Which brake pads should be used?
The original brake pads from the brake caliper, which is required for our conversion kit, must always be used.
- Can I use other brake calipers as indicated in the required components?
No, unfortunately that is not possible, the reason being that all brake calipers have different height and depth measurements. If another brake disc is installed, the brake caliper would either not fit the adapter at all or not run centrally to the brake disc. If you want to install a different brake caliper, we also have an option for you. You can have a custom-made product manufactured, check out the following link for more information:
- Can I also use other discs as specified in the required components?
No, unfortunately that is not possible. The reason is simply that all brake calipers have different height and depth measurements. If a different brake disc is installed, the brake caliper would either not fit on the adapter at all or would not be centered with the brake disc. However, if you want to install a different brake caliper, we also have an option for you. You can have a custom-made product produced, have a look at the following link for more information:
