Checking brake stroke tells a technician a lot about a braking system’s mechanical condition – everything, that is, but the actual brake torque, or the ability of the system to stop the truck. Critical factors like low-friction brake lining, poor shoe-to-drum fit or lube on the linings won’t be indicated by a stroke test.
The testers described here measure the actual ability of the brake system to produce stopping force, and will tip you off to just about any performance problem. In addition, the units may be able to test ABS, traction or stability control, or wheel alignment at the same time.
These diagnostic tools could provide a cost-effective means of improving your maintenance shop’s ability to keep your trucks safe and road-ready.
