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 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.
