Automatic slack adjuster
摘要:
A slack adjuster for a vehicle drum brake includes a pinion that rotates about a worm axis whenever the slack adjuster pivots. Excess clearance is taken up upon commencement of the apply stroke, at an accelerated rate. This enables a larger amount of initial clearance to be built into the brake.
