BRAKE AIR CHAMBERS
After exiting either the ABS front relay valve or the ABS ECU, the hose assembly is plumbed directly to
the brake air chambers.
The cam-actuated type brake design uses singe brake air chambers per brake.
Within the brake air chambers, air pressure is converted to mechanical force to create braking action.
