 We hold the STC for the Brake Boosters (formerly owned by North River Aviation) and stock the conversion kits and replacement parts. This kit upgrades the Scott brake master cylinders for many Piper models.
Brake Booster Technical Information
To be eligible for installation of the brake booster, the airplane must be equipped with FAA approved high-pressure brake lines. "FAA approved high-pressure brake lines" are brake lines which the FAA has found to be sufficiently flexible for their intended purpose, compatible with MIL-H-5606BB (red) hydraulic fluid, and capable of sustaining an ultimate hydraulic pressure of 2547 PSI for at least 3 seconds without failure or leakage; and which the FAA has approved for installation on the airplane. Any wheel/brake assembly installed on an airplane equipped with the brake booster must have a brake FAA approved for a maximum available hydraulic pressure of at least 1698 PSI as defined by the brake's original certification basis (TSO-C26, TSO-C26a, TSO-C26b, or TSO-C26c; or the airplane's certification basis if the brakes were approved as part of the airplane type design).
