Medium Duty Calipers

🛑 CRITICAL: Verify Specifications

Severe brake pull, rapid pad wear, or complete caliper lockup can occur if your replacement cylinder metrics deviate from original vehicle blueprints. Before processing your order or completing checkout, cross-verify your original housing properties across these core technical layout baselines:

• Piston Sizing & Count: Verify your original requirements, confirming if your assembly relies on a dual piston structure, a quad piston layout, or alternative precise standard measurements to secure proper pad load distribution.
• Inlet Configuration: Confirm fluid feed line port thread configurations, checking for exact INV (inverted flare) line settings or specialized banjo bolt sizing to prevent high-pressure line fluid drops.
• Bracket Orientation: Match the mounting bolt hole spacing and sliding pin configurations straight against your steering knuckle setup.
• Companion Upgrades: Check our catalog for a linked companion repair kit, guide pins, replacement brake pads, or severe-duty rotors to completely refresh the axle line during component swaps.

Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes since 1985, structural caliper tracking failures or dragging pads are frequently caused by failing to service the slider tracks and guide pin sleeves during component replacement. If the sliding pins operate at an uncentered or unlubricated angle, it introduces extreme side-loading force. This side-loading scores the internal piston bore and destroys the internal piston seals, causing rapid high-pressure leaks. Always clean your caliper brackets, verify absolute pushrod alignment throughout the hydraulic link network, and thoroughly flush the lines to eliminate old fluid and moisture before releasing fleet vehicles back to operation.
