âš Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985:
- Pushrod Alignment: Verify the Long Forked rod orientation matches your original pedal linkage. Proper geometry is vital to prevent side-loading internal piston seals.
- Legacy Conversion: If you are replacing an older style Hydromax (Casting #2771424 or #2771819) with a 1-pin flow switch, you MUST purchase Flow Switch Adapter SKU 529999.
- Hardware Note: New Oval O-rings for the pump motor are included. Ensure mounting surfaces are clean before installation.
- Core Refund: Return your old, like-for-like core within 90 days to receive a $50.00 refund.
