Overview
The Power Stop K1781-36 is a front Heavy Duty Truck and Tow brake kit for the 2005–2008 Ford F-250 Super Duty and the 2005–2011 Ford F-350 Super Duty. It combines slotted and cross-drilled rotors with Z36 high-friction metallic pads and has no calipers.
Power Stop presents the kit as heavy-duty braking for trucks that work in wet, hot or hilly conditions or tow at maximum weight. Power Stop adds that the K1781-36 rotors are coated, that brake lines are left out, and that it is a direct fit. Super Duty owners looking for the front axle of an older F-250 or F-350 will find that the K1781-36 is the front half of a pair; Power Stop sells rear and combined kits under other part numbers. Cross-drilled rotors have holes through the friction face and slotted rotors have grooves, and this kit uses both patterns on coated rotors.
Key features
- Front kit pairing slotted and cross-drilled rotors with Z36 metallic pads.
- Intended by Power Stop for heavy-duty and towing use.
- Coated rotors.
- The F-250 covers 2005–2008 and the F-350 covers 2005–2011.
- No calipers and no brake lines come with it.
Heavy duty brake work
Heavy trucks and tow rigs put more heat into the brakes than passenger vehicles, so the pads and rotors work harder on long descents and at maximum weight. Friction materials that suit this kind of driving usually run warmer and produce more dust. Check that the calipers, hoses and hub bearings are in good condition, since these parts carry the same load as the new pads and rotors.
Because the calipers stay on the truck, inspect their slide pins, piston movement and seals before fitting the rotors and pads. A seized caliper can drag, overheat the new rotors and wear pads unevenly. Bed in the new pads with gentle stops before loaded trips, and re-check fasteners after the first few days of driving.
- Inspect caliper slide pins and seals
- Check the brake lines for cracks or swelling
- Bed in pads before a loaded trip
