Lambretta Brake Upgrade: Spring for Pump under Nose

In the context of technical upgrades for Lambretta, one of the most effective modifications concerns the front braking system, particularly when a horn-cast mounted brake master cylinder is installed. In this configuration, the use of a dedicated return spring is an essential functional component to optimise the brake lever return.

Function of the return spring

The tension spring ensures a precise and smooth return of the brake lever after each actuation. This is particularly important in non-standard configurations, where the brake master cylinder is mounted under the horn casting using a dedicated bracket. In such cases, the absence of an adequate return spring can lead to lever play, imprecise response, or increased control fatigue.

Technical specifications

• Application: front brake systems with master cylinder mounted under the horn casting.

• Total length: 32.40 mm

• Installation: simple, compatible with master cylinder.

Advantages of the upgrade

• Improved precision in brake lever return.

• Improved braking feel

• Long-term reliability

• Ideal for custom builds and restorations

“When to install it

The use of the spring is recommended exclusively when the brake master cylinder is mounted under the horn casting, a typical configuration in Lambretta modifications involving the integration of a hydraulic braking system. In this setup, the spring works optimally by providing the correct tension for lever return, significantly improving the overall functionality of the brake control.
