Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing to prevent chaffing and damage. Always check for adequate twist clearance during full-lock steering cycles and verify line mounting bracket integrity on heavy commercial frames. Proper installation ensures maximum caliper lifespan and optimal brake response under severe-duty conditions.
Before ordering, physically inspect your existing caliper, line length, banjos, and flare fitting threads. Variations in vehicle wheelbase and mid-year production changes can alter routing and mounting points. Confirm these details to ensure compatibility and avoid installation delays.
