Restomotive Hydraulic Handbrakes – Composite and Billet

Hydraulic handbrakes are one of the key components in performance and competition cars. Their role is to provide precise and repeatable operation in situations where a traditional mechanical handbrake falls short — especially in drifting, rallycross, or track driving.

We’ve prepared two models of this component: the Composite Hydraulic Handbrake and the Billet Hydraulic Handbrake. Both have been designed for drivers who demand the highest quality, ergonomics, and reliability.

Why a Hydraulic Handbrake?

A standard cable-operated handbrake often cannot generate sufficient braking force or provide consistent performance. The solution is a hydraulic handbrake, operating on a separate hydraulic master cylinder independent of the stock braking system.

This setup gives the driver much greater control and allows precise modulation of rear-axle braking force.

Composite Hydraulic Handbrake

The first option is the composite version, with a core made of composite reinforced with carbon fiber and key elements such as the pump base manufactured from PA9 (7075) aluminum. This material combination ensures high stiffness while keeping the weight low.

The design was developed using modern CAD tools and verified through FEA testing, ensuring the structure can handle demanding track conditions. Additionally, all surfaces are anodized for wear protection and a premium look.

The composite handbrake is the ideal solution for drivers who want to enhance their car’s performance while seeking a balance between weight, cost, and durability.

Billet Hydraulic Handbrake

The second version is the billet model, made entirely from CNC-machined 7075 (PA9) aluminum — an exceptionally strong material widely used in aerospace and motorsport. Both the body and the lever are precisely machined on CNC equipment, with anodizing applied for protection and finish.

The key difference compared to the composite version is the long, well-balanced lever. This provides even greater precision and feel during operation, which is crucial in drifting, where fractions of a second and subtle differences in braking force make all the difference.

The billet handbrake is built for the most demanding users — those who push their cars to the limit and require equipment that can withstand extreme loads.

Similarities and Differences

What both models share:

• Designed to work with an independent hydraulic master cylinder

• CAD-designed and FEA-tested

• Anodized surface for wear protection

• Motorsport application

Key differences:

• Composite model combines lightness with strength and is more cost-effective.

• Billet model offers maximum rigidity, durability, and precision, at a higher cost and slightly greater weight.

Summary

The choice between composite and billet versions comes down to driving style and driver expectations.

• If you’re looking for a balance between price, weight, and durability, the Composite Hydraulic Handbrake is the perfect solution.

• If your car spends most of its time on the track and you need absolute confidence and maximum precision, the Billet Hydraulic Handbrake is the best choice.
