Manual Brakes - Pedal Box & Balance Bar Assembly / Tandem Master Cylinder & Adjustable Proportioning Valve
We build brakes for race cars; not that some don’t see street use, some are even used predominantly on the street, but at our core, we are a racing brake company. Race cars have manual brakes. The reason is simple, the purpose of a race car is to go as fast as possible as simply as possible. All sorts of complexity has come into racing over the years: EFI, multi-adjustable shocks, traction control, bumpstops, etc. The one thing all of these technologies offer is better performance in exchange for higher complexity. Power brakes do not offer this trade-off, they offer added complexity and weight without added performance.
Anyone in the process of building or refitting a race car should seriously consider a pedal box / balance bar assembly as their primary choice for a master cylinder arrangement. The balance bar, also called a “dual master” system, mounts two single circuit master cylinders side by side and has an adjustable mechanical linkage between the two masters to adjust the front-to-rear proportioning.
The second choice offers less adjustability, but can work acceptably well if rules or finances dictate. This is a factory style tandem master combined with an adjustable proportioning valve to balance the system.
