CRITICAL: Verify Specifications & Mounting Type

Please note: This unit does NOT include a mounting bracket (reuse existing firewall mounting assembly). Confirm your housing diameter (2.16 in) and stud thread size (10 x 1.25mm) prior to installation. Commercial step vans and stripped chassis vehicles require precise hydraulic assist specifications to guarantee safe stopping under heavy route loads and full motorhome GVWR ratings.

🛠️ Expert Installation & Field Note

From our shop experience specializing in commercial step van and heavy-duty brakes since 1985:

Pushrod Alignment: Ensure your pedal pushrod linkage aligns completely straight during installation. On P30 and P3500 forward-control cabs, off-angle pushrod travel will score internal piston seals, leading to rapid pressure loss and hydraulic fluid bypass.
Hydraulic System Flush: Hydroboost units are extremely sensitive to metallic debris and oxidized power steering fluid. We mandate a complete fluid flush before installing this unit to protect the new internal spool valves and check valves.
Corrosion Protection: Our exclusive rust-prohibitive finishing process seals raw iron castings from road salt, water spray, and severe environmental exposure common in commercial route operations.
