ABSTRACT:
A friction disc test machine has a cavity in which alternately spaced stationary and rotary friction discs are disposed. The friction discs are urged into engagement by a selectively actuatable fluid operated piston to bring the rotating discs to a halt. An end cover and balance reaction piston are provided to limit the axial disc movement. The balance reaction piston is slidably disposed in a cavity formed in the end cover for linear and angular movement relative thereto. One friction disc abuts the balance piston whereby, due to the alignment properties of the piston, all of the friction discs are maintained in parallel alignment during engagement therebetween.
