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: https://epytec.de/uk/custom-made-products/brake-technology/adapters-for-brake-systems

My brake caliper is not exactly centered over the brake disc - what should I do?

If your brake caliper is not exactly centered over the brake disc, in most cases it is not a problem. Depending on the vehicle, model year, and mileage, axle tolerances can occur – and this even in newer vehicles.The most important thing is:👉 The brake caliper must have sufficient clearance on the left and right to the brake disc so that nothing rubs or permanently touches it.Many brake calipers also have locking bolts. It may happen that:there is very little clearance on one side or the bolt lightly toucheswhile on the other side there is more playThis is generally not critical.🔧 This is how you proceed:Install brake pads:First check if the brake pads can be inserted cleanly and without resistance on both sides.If everything fits:If installation is possible without problems, you can simply gently push back the locking bolts – this usually resolves the issue.If it jams:If the brake pads cannot be installed, or only with difficulty, on one side, action is required.In this case, you can:slightly shim the adapter with suitable bushings to adjust the brake caliperor – depending on the situation – slightly mill the adapter so that the brake caliper is correctly centered again👉 The goal is always that the brake caliper is evenly aligned with the brake disc and the brake pads are seated freely and cleanly.

We provide a TÜV certificate with this adapter. This means that the TÜV inspector can easily register the adapter.

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.

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.

Extrem hochwertige Ware, mit super schneller Lieferzeit. Allen TT Fahrern die mit den Originalen Bremsen unzufrieden sind, empfehle ich dieses Produkt für den Umbau. Das Ergebnis nach dem Einbau kann sich sehen lassen.
