?️ Expert Installation & Shop Note

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

Pushrod Alignment: Ensure the pushrod is perfectly centered during installation. Misalignment on P-Series chassis can lead to premature seal scoring and internal bypass.
Hydraulic Contamination: These units share a reservoir with the power steering pump. We strongly recommend a complete system flush with fresh fluid. Contaminated oil is the #1 cause of return-line blockage.
Step Van Fatigue: Frequent stop-and-go delivery cycles accelerate seal wear. Our exclusive rust-prohibitive finishing process protects the cast iron housing against corrosive environmental conditions common in fleet work.
