A system modification exists for certain vehicles, specifically those within the Fox body Ford platform, to replace the original power-assisted braking system with a manually operated one. This alteration involves removing components such as the power brake booster and master cylinder, and installing a new master cylinder designed for manual operation, along with necessary modifications to the brake pedal linkage.
This adjustment offers several advantages, including reduced weight, simplified engine bay clutter, and enhanced pedal feel, providing the driver with more direct feedback from the braking system. Historically, this type of modification was implemented in racing applications where the added precision and control over braking forces were crucial for performance. Furthermore, in certain instances, this swap can improve overall vehicle reliability by removing a potential failure point associated with power assist systems.
