The original Triumph system uses a single master cylinder mounted to a vacuum brake booster. Front to rear brake bias cannot be adjusted and the vacuum booster causes a “vague” or “disconnected” brake pedal sensation. Good Parts Dual Master Cylinder Kit uses two 5/8″ bore Wilwood master cylinders and a balance bar system to allow full adjustment of front to rear brake bias. Bias adjustment may be made at the balance bar or from the cockpit using the Remote Brake Bias Adjuster Kit (SKU 3799). The vacuum booster is replaced by an adjustable mechanical lever within the assembly that increases brake pedal force and provides a direct and repeatable brake pedal response.
This kit is sold as a complete bolt-on assembly that replaces the original vacuum booster and master cylinder. Includes new brake lines to connect between the master cylinder and the original brake pressure differential warning assembly (PDWA).
Fits left hand drive cars as shown with direct mounted reservoirs. Can be fitted to right hand drive cars by using the included remote reservoir mounting kit.
