Automatic Adjusters for Passenger Car Disc Brakes

Accurate adjuster clearance is of vital importance in large passenger cars. It directly improves parking brake effectiveness with any operating system and in addition more than doubles the advantage which can be gained from variable velocity ratio linkage's. Good knock back resistance and load insensitivity are the essential qualities which an adjuster must have to achieve accurate clearance control. A new type of adjuster has been designed which is specially well protected from pad knockback effects, and also provides load insensitivity without the customary use of an extra hydraulic seal.
