Spring brake valves are designed for three
primary functions: |
1. To fill the reservoirs 2. To release the spring brake
side of the brake chamber. 3. Engage the spring brakes for parking and
during emergency situations such as breakaway. A more detailed description can
be found in the Tech section About subsection. |
Notes: |
This is a simplified description and does not take into
account service brake operations, specific model features, or additional built
in protections.
The spring side of a brake chamber will release the
brakes when ample air pressure is supplied. This is opposite of the service
side of the chamber. |
