Tilton lever-type proportioning valves enable adjustable brake line pressure reduction to a particular wheel or wheels. They can also be used effectively with single or dual master cylinder systems, providing better front-to-rear brake balance under both light and heavy braking. Tilton’s lever-type proportioning valve provides a visual reference for seven distinct positions: Seven notched pre-determined pressure positions. Wide clearly labeled handle. Precision-machined billet aluminium body. Metric 10mm inlet ports. We can also make FULL in-car brake line kits to suit. We manufacture brake line kits in-house for TEGIWA Civic Cup, part of 750MC.
