🛠️ Expert Installation & Field Note

From our shop experience specializing in heavy-duty commercial hydraulic braking systems since 1985:

Power Steering Fluid Purge: GM full-size van engine doghouses retain significant heat. Always perform a total power steering fluid flush before installation to clear trapped debris that can stick internal spool valves or damage shaft seals.
Pedal Linkage Alignment: Inspect the pedal pushrod attachment at the firewall mounting bracket during reassembly to ensure straight actuation without side binding, which prevents premature seal wear.
Anti-Corrosion Finish: Our proprietary black protective coating shields raw cast iron against road salt, moisture, and fleet chemical washdown.
