Does this sound like you?

  • The manual never endsOver 150 pages of text, and it's hard to tell what the test will actually ask.
  • Air brakes make no senseCompressor, governor, spring brakes. Hard to picture parts you've never seen.
  • So many parts to nameSteering, wheels, air lines, fifth wheel. Each part has its own check.
  • The numbers blur togetherAir pressure, following distance, feet to stop. They start to mix.

If any of these sound familiar, you're in the right place.

Know when the spring brakes come on

55 or 20 to 45? The manual puts both numbers a few lines apart. Which one puts the spring brakes on?

Air brakes, page 74. Tap to see it full size.

55 psi is the warning. The spring brakes come on at 20 to 45 psi.
