Practice question

A vehicle's governor cuts out at 125 psi. After several brake applications, pressure falls to 105 psi and the compressor starts building again. Is this behavior consistent with the ICBC guide?

  1. Yes; a roughly 20 psi spread between cut-out and cut-in is typical
  2. No; the compressor must not restart until 60 psi
  3. No; cut-in must be exactly 125 psi
  4. No; the governor should only control ABS

Answer: A — Yes; a roughly 20 psi spread between cut-out and cut-in is typical
