Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper line routing to prevent chassis chaffing and twisted fittings during full-lock steering cycles. Always verify mounting bracket positions on heavy commercial frames to ensure caliper longevity and optimal hydraulic performance. Proper routing and secure mounting are critical for maintaining fleet safety and avoiding premature component failure.
Before ordering, physically inspect your existing line length, banjos, or flare fitting threads. Fleet and utility applications often have mid-year production changes or wheelbase variations that alter line routing. Confirm all dimensions and fittings to ensure compatibility and avoid retrofit delays.
