L-1011 Landing Gear and Brakes: Mechanical Brakes (32-19)


The Lockheed L-1011 uses hydraulically actuated multiple disk type brakes. The brakes are self-adjusting and incorporate direct mechanical wear indicators at the disk.

The brake system uses a dual cable run from the brake pedals back to the dual brake valve located in the hydraulic service center. The Captain's cable run controls system "B" dual brake valve and the First Officer's control system "C". Both dual brake valves are mechanically linked together. Either operator exercises both brake valves simultaneously. A bunge system is incorporated outboard of each brake valve to protect against possible jams.
