Bendix Brakes won't air up

[Ralph L. Fullenwider]

Great Al:

Not a glitch, it will happen again. Bet on it. They replaced the filter,
good, but did not rebuild the pop off valve and that is what your problem
is. The re build kit is around $15.00 and can be had at or through
O'Riely's or Napa. You can do the rebuild when you get to home base.

Have a good trip.
