ManufacturerIndividual Racing Parts
A hydraulic handbrake acts directly on the rear calipers. It locks the axle without using cables, providing clean, repeatable locking - something the factory cable can no longer do once the car gains weight or grip.
The master cylinder bore is not a minor detail. The smaller it is, the faster pressure rises for the same lever effort, but the longer the stroke becomes. A 0.75" bore suits most stock rear calipers; a larger bore is reserved for calipers with large pistons.
Dual-master-cylinder setup: it completely separates the handbrake circuit from the pedal circuit. Safer in competition, but it requires independent bleeding.
