Overview

The Scott Brake Master Cylinder is one of the largest selling aircraft master cylinders in the world. Installed as standard equipment on Piper and other aircraft for many years, these units provide rugged and virtually trouble-free service with few wearing parts. One pair of master cylinders – one left hand (1248H) and one right hand (1260H) – is required on most aircraft. On the Piper Tri-Pacer, however, only one left master cylinder (1248H) is required.

Reviews

As described, fit well, functions fine. Its a flat piece of rubber with a bunch of holes, so not too much else to say.
