Glossary Term Description Adjustment Method whereby the slack adjuster maintains the correct clearance. Alpha Angle The angle of the control arm in fitting position. Anchor Bolt Used to attach the fixed point to the vehicle. Anchor Point The bracket, attached to the vehicle which connects to the control arm of th Body The part of the adjuster which houses the mechanism and extends to hold Bracket Kit Loose parts supplied with Fast-Fit automatic slack adjusters. Casting The part of the adjuster which houses the mechanism and extends to hold Casting Number Identification number for each body type, marked in relief on the casting. Clearance The distance between brake lining and drum. Clearance Sensing Principle Where the clearance is maintained by measuring wear, but not elasticity, in Clevis Bush The bush in the slack adjuster body where the air chamber is connected to Control Arm The rotating arm, which connects the cover plate to the anchor point. Control Unit The specific cover plate, control arm and alpha angle combination for a par Control Unit number Identification number for the specific combination of control arm and alpha Cover Plate The metal pressing which is screwed to the body to protect the mechanism.
