INTRODUCTION
The Spring Applied Air Release (SAAR) Brake Assembly (P/N 77010008) may be used
to replace the hydraulic brake on model 224 dynamometers. This guide provides
instructions for removing the hydraulic brake and installing the SAAR brake assembly.
The SAAR brake provides braking to the dyno drum through the use of a spring
applied brake mechanism. By default, the brake shoes are pressed against the dyno
drum by the spring mechanism. Air applied to the SAAR brake moves the brake shoes
away from the drum, releasing the brake.
The SAAR brake provides the following advantages over the previous hydraulic brake:
• Vehicles are easier to load since the SAAR brake is applied when the dyno is idle
• The SAAR brake provides braking in the event of a loss of power or an air supply
failure.
• Brake maintenance is reduced as the SAAR brake does not need the filling and
bleeding required for hydraulic brakes.
For more detailed information on the 224 dyno, refer to the Installation Guide for
Model 224 Above Ground Automotive Dynamometers (P/N 98210108) or the
Installation Guide for In Ground Model 224 Automotive Dynamometers (P/N
98210100).
