One of the recent purchases at work had ineffective brakes. Checked to see air was being applied to all the chambers - all good - then found out that the back brakes were working, but the fronts appeared to be doing nothing. Pulled the front chambers apart and manually actuated the plunger to see if it appeared to be doing anything at the wheel end - nothing.
Pulled the wheel off today, repeated the same experiment. Plunger goes all the way in, nothing happens at the wedge brake. Pulled the wedge brake assembly apart and...laughed my head off for ten minutes straight.
They'd put the front brakes back together with no wedge brake expanders. Nothing. So there was nothing to drive the wedges apart upon a brake application. The plunger driven by the air chamber just pushed away on into free space. No wonder it sent the front axle into LOW AIR after a couple of applications. All the parts are nice and new, however - it's just (lol) - there aren't *enough* of them![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Anyhow, this one came out of Ft. Campbell in Kentucky, ex-101AB. Be advised.
