Bremsenhex - Magic for the Vespa and Lambretta

Created by Dietrich Limper at 10:03 on June 30, 2025

The brakes are one of the most important safety systems on a scooter. However, many riders are familiar with the problem: despite new Brake Pads, the braking performance falls short of expectations. This is often because the Brake Pads do not fit the Brake Drum perfectly and therefore only grip at certain points. The consequences are reduced braking force, uneven wear and, in the worst case, even a safety risk.

This is where the Brake Hex SIP Performance comes in - an innovative Tool that mills the Brake Pads exactly round and adapts them perfectly to the Brake Drum. Developed in Austria and made ready for series production by SIP Scootershop, this tool significantly improves braking performance and safety.

Why is the SIP Performance brake hex necessary?

New Brake Pads often have minimal manufacturing tolerances or are not precisely matched to the diameter of the Brake Drum. This results in an uneven contact surface, which significantly reduces the braking force. Older Brake Pads in particular, which wear unevenly, exacerbate this problem and can lead to dangerous point loads.

The solution? The Brake Pads must be precisely matched to the inner diameter of the Brake Drum - and this is exactly what the Brake Hex SIP Performance does.

How does the Bremsenhex SIP Performance work?

The application is very simple:

  • The matching adaptor is fitted to the Wheel Hub.

  • The pneumatic tool with milling cutter is screwed onto the Adaptor.

  • The perfect diameter of the Brake Pads is achieved by careful milling.

The result: The Brake Pads fit evenly, the contact surface is maximised and the braking force is significantly increased.

The three biggest advantages of the Brake Hex SIP Performance

1. Perfect adjustment for maximum braking force

The Bremsenhex mills the Brake Pads exactly round and thus ensures even and large-area contact in the Brake Drum. This results in an optimum braking effect, which is particularly noticeable in shorter braking distances and better modulation.

2. Elevation in braking performance and greater safety

The enlarged contact surface of the Brake Pads noticeably improves the braking force. This not only ensures more direct deceleration, but also increases safety, especially in critical riding situations or in wet conditions.

3. Versatile application for numerous scooter models

The SIP Performance brake hex is not limited to a specific model. Thanks to various adaptors, it can be used for a wide range of scooters with Drum Brake, whether Vespa, Lambretta or other brands.

Durability and ease of use

Another major advantage of the Brake Pads Hex is the even wear of the Brake Pads. As these are perfectly adapted to the drum, punctual wear is avoided and the service life of the linings is extended. The ease of use makes the Tool interesting for both hobby mechanics and professionals.

Conclusion: More braking power, more safety, more riding pleasure

The Bremsenhex SIP Performance is the ideal tool for anyone who wants to optimise the braking performance of their scooter. The precise adjustment of the Brake Pads to the Brake Drum results in a significantly improved braking effect, which increases both safety and riding comfort.

Note: The brake hex is not offered as a set. The basic part is the Bracket, the matching Adaptor for the respective scooter model is available separately.
