The mechanism is such that the ASA distinguishes between the three portions of the braking stroke and, unlike stroke sensing ASA's, only adjusts in the appropriate portion. When brakes are applied the stroke moves through:

1. The normal pre-set running clearance A for which no adjustment should be made;

2. The excess clearance B, which develops when linings and drums wear and for which adjustment should be made;

3. The elasticity of the braking system C which is caused by variable brake load, drum expansion and component flexibility, and for which no adjustment should be made.

With stroke sensing ASA's, at best the running clearance has to be wider, which reduces braking efficiency, and at worst brakes which have been over adjusted during the elasticity portion of the stroke may be left with no running clearance at all.
