Cleveland’s Pull-type master cylinders are an alternative to push-type master cylinders and are common in the general aviation market.

&nbsp;

Pull-type master cylinders are used when the aircraft’s linkage is not set up for a push-type master cylinder due to cockpit design constraints or the air framer’s preference. The pull-type master cylinder will require a larger bore than a pull-type master cylinder with the same volume output. The effective area of the piston is reduced due to the area of the master cylinder’s rod. The aircraft’s brake pedal linkage is set up to pull the rod of the master cylinder to engage the brake discs.

&nbsp;

&nbsp;

Once the brake discs are engaged, the master cylinder transforms the pilot’s input force into a hydraulic pressure at the brakes. The brake pistons then reverse the process and transform the hydraulic pressure into a force against the brake discs. This force is used to stop the discs from rotating and ultimately stop the aircraft.

&nbsp;

&nbsp;

Selection of a properly sized master cylinder is important. There are several features to consider when choosing a master cylinder. Volume Output is the most important and is governed by the volume requirement of the brakes and the compliance of the rest of the system. Choosing a master cylinder with too low a volume output will not allow the brakes to be filled properly and perhaps not pressurized enough to stop the aircraft.

&nbsp;

&nbsp;

The master cylinder’s Bore Size directly affects the amount of pedal effort. A large bore master cylinder will make the pedal effort higher than one with a smaller bore.

Reservoir Master Cylinders

10-69

Pull-type Reservoir master cylinders incorporate the reservoir into the body of the valve to eliminate the need for an additional reservoir and the associated plumbing.  Our master cylinders utilize hardened steel rods, aluminum housings, and pistons that have low seal friction, which means they are designed for long, reliable service life.
