Abstract:
A brake apparatus, comprising,a brake disk secured to a shaft; a reaction plate secured to a housing; a fluid actuated piston having a contact surface which urges the brake disk against the reaction plate to slow rotation of the shaft; an adjustment member positioned by the contact surface, the adjustment member being mounted within and slideable relative to the reaction plate; a pin including a first portion engaged with the piston, the pin having a second portion in a sliding friction relationship with the adjustment member, wherein the pin extends between the piston and the reaction plate; and a spring retained between the adjustment member and the the reaction plate, wherein: the contact surface positions the adjustment member through movement of the pin relative to the brake disk when fluid is applied to the piston, and the spring urges the contact surface away from the adjustment member and brake disk when fluid pressure is removed from the piston.
