Brake caliper adapter, rear axle, on all 4WD models Golf MK4 Bora Vento Audi A3, etc, for conversion to Porsche Cayenne caliper, combined with the 310x22 mm VW Phaeton brake discs, rear.
The Porsche calipers are connected to the hydraulics of the vehicle and can thus develop an enormous braking force. However, these do not have handbrake functions. The rear axle of Audi S3 or Golf MK4 R32 is additionally used for a handbrake brake caliper adapter. The hydraulic connection is thereby closed with a blind plug / closure cap, thus this serves only as a hand brake caliper.
Thanks to the plates, the track is 15 mn wider per side.

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

Very good quality new in condition great value for money well packaged great appearance good postage rate as described perfect very happy with this purchase
- 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
