INSTALLATION PROCEDURE
IMPORTANT: When replacing the ABS brake modulator, install the three gears in the same location on the replacement brake modulator.
No repair of the ABS brake modulator is authorized. Replace the ABS brake modulator as an assembly.
IMPORTANT: Use new transfer tube assemblies when assembling the proportioning valve to the hydraulic brake modulator. Be sure to properly install
two O-rings on each transfer tube.
1. Use the following procedure in order to install the two transfer assemblies:
1. 1. Lubricate the transfer tube assembly O-rings with clean brake fluid.
1. 2. Install the transfer tube assemblies into ports of the ABS hydraulic brake modulator.
Push the tube assemblies in by hand to the bottom of the ports.
2. Lubricate the new banjo bolt O-rings with clean brake fluid.
3. Install the banjo bolt O-rings into the ABS hydraulic brake modulator and the proportioning valve.
