A system designed to replace a vehicle’s power-assisted braking with a mechanically actuated system. These assemblies typically consist of a master cylinder, pushrod, and necessary hardware to facilitate the change. The purpose is to remove reliance on a vacuum booster, which can improve pedal feel and provide more direct control over braking force.
The utilization of a mechanically actuated system offers advantages in specific applications, such as racing or vehicles with modified engines that produce insufficient vacuum for power-assisted brakes. Removing the power assist can lead to weight reduction, simplified engine bay layouts, and enhanced feedback to the driver. Historically, these systems were common before the widespread adoption of vacuum-assisted braking and are experiencing a resurgence in certain performance-oriented sectors.
