Abstract

A brake adjustment indicator for a braking system including a pressure chamber, a pushrod extending longitudinally outwards from the pressure chamber and moveable when correctly adjusted between first and second positions, a brake arm and a pivot for pivotally mounting the pushrod to the brake arm. The brake adjustment indicator comprises an indicator adapted to be mounted for longitudinal movement with the pushrod, a support having a first portion and a second portion, the first portion adapted to be mounted to the vehicle, the support configured to position the second portion opposite to the indicator and first and second reference pointers fixedly positionable on the second portion for marking the first and second positions. A spacer is provided for positioning the first reference pointer in a preselected position relative to the second reference pointer. The first and second reference pointers are mounted for simultaneous movement on the second portion.
