FAQ: Häufige Fragen
Sollte ich die Anker- bzw. Staubbleche entfernen?
Wir empfehlen das Entfernen der Bleche, da sie die Belüftung einschränken. Ohne diese Barriere wird die Bremse effizienter gekühlt und bleibt auch bei starker Beanspruchung leistungsfähig.
Wie erleichtere ich mir die Felgenmontage?
Mit Radmontagehilfen gelingt das Ausrichten und Aufsetzen der Felge einfacher und präziser. Das schützt Gewinde und Felge und spart Zeit.
Benötige ich Spurverbreiterungen nach dem Umbau?
Welche Felgengröße passt, lässt sich pauschal nicht sagen. Streift die Felge minimal am Bremssattel, schaffen Spurverbreiterungen den nötigen Abstand.
Brauche ich neue Bremsleitungen?
Für optimale Passform und stabile Bremswirkung empfehlen wir Stahlflex. Diese sind konfigurierbar und liefern konstantere Ergebnisse als Gummileitungen.
Warum unsere Adapter die beste Wahl sind
Wusstest du, dass sich dein EPYTEC-Adapter oft schon nach dem ersten Verschleißteilwechsel komplett bezahlt macht?
Das liegt daran, dass du mit unseren Adaptern auf OE-Bremsscheiben und -Sättel setzt, die wir bewusst bei der Entwicklung der Adapter ausgewählt haben. Diese Komponenten sind nicht nur in höchster Qualität gefertigt und in Serienfahrzeugen im Einsatz, sondern durch ihre Großserienproduktion auch günstig und jederzeit verfügbar.
Für dich bedeutet das: erstklassige Bremsleistung ohne Abhängigkeit von teuren Speziallösungen anderer Hersteller.
Und selbst beim TÜV hast du es leichter, denn unsere OE-Komponenten sind bereits offiziell abgenommen – der Prüfer kann sich direkt darauf beziehen, sodass deine Eintragung unkompliziert und sicher abläuft.
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.

- 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:

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 touches
while on the other side there is more play
This 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 caliper
or – 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.
