Brake master cylinder 271984 Manitou, aftermarket

Brake master cylinder 271984 is an aftermarket part for the Manitou telehandlers.

The brake master cylinder turns the force the operator applies to the pedal into fluid pressure and sends it through the brake lines to the brake pistons. When the pedal is pressed, the cylinder piston moves forward, the main cup seal closes the feed port and pushes fluid into the line; when the pedal is released, a spring returns the piston and fluid refills from the reservoir. Worn internal seals make the pedal sink slowly, delay braking or make one side brake more weakly. Leaks from the body or at the pedal end also show that the cylinder needs replacing. The pedal latch and the pedal return springs are checked too, as a sticking pedal will stop a new cylinder from returning fully as well.
