🛠️ Expert Installation & Field Note

From our shop experience specializing in heavy-duty brakes since 1985:

Pushrod Alignment: Ensure your firewall pedal pushrod runs completely centered during installation. On early GM G-Body applications, an uneven pushrod path can lead to fast internal seal scoring and premature leakage.
Hydraulic System Flush: Hydraulic boosters are highly sensitive to abrasive debris trapped inside old fluid lines. We mandate a complete power steering system flush with fresh fluid before connecting this unit to protect the new internal check valves.
Corrosion Barrier: Our exclusive rust-prohibitive finishing process seals the raw iron casing against moisture and road chemicals, preventing external degradation over extended cycles.
