âš Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985:
- Pushrod Alignment: Proper pushrod alignment is critical on the newer Silverado chassis. The short single eyelet rod is pre-installed to factory specifications. Ensure the eyelet pin is lubricated with high-temp brake grease to prevent premature wear on the pedal pivot.
- Hydraulic Seal Integrity: New Oval O-rings are provided and must be used. Reusing old seals is the primary cause of hydraulic fluid bypass at the pump motor flange.
- Fleet Reliability: This unit is built for heavy-duty fleet reliability. When replacing, we recommend flushing the entire hydraulic system with fresh fluid to ensure no contaminants from the old booster damage the new internal seals.
