Had a customer bring in a D38E to change oil and filters, replace belt tensioner, and look the machine over kinda stuff. Got everything done, including cleaning his OMG clogged radiator.
Was driving it on the lot today checking it out and noticed the master brake pedal didn't do anything. Hmm. Now I don't know a whole lot about the D38E, but I know the master brake pedal directly operates a control valve, and I know the valve spool is operating. Hmm. So I tried driving the machine and throwing down the safety lever, still didn't engage master brake/parking brake. Hmm. I'm going to let customer know this on Monday and see if he wants me to look into problem, 'tis a bit dangerous like this. Anybody know the nuts and bolts of the master brake/parking brake operation on this machine? Steering brakes work fine for steering, just a problem with master brake.
