BC Transit – Air Brake Course

“Maxi-Brake” Operation (Emergency Release Reservoir)
If a loss of system air occurs, and the operator needs to move the vehicle a short
distance to safety, opening the park brake control valve and the emergency release
reservoir valve at the same time, will allow the air in the emergency release
reservoir to flow through to the spring brakes, holding them in release.
