Know which spindle you have?
Wilwood 140-10510-DR has red six-piston Dynapro 6 calipers and 12.19-inch drilled and slotted rotors. Figure out the spindle and the original brake setup before you pick this kit.
Match the application
Use the exact manufacturer application row for the vehicle and spindle. Factory-disc, factory-drum and Ridetech Pin Spindle entries are separate conditions. Ford/Mercury applications require the listed Ridetech Pin Spindles; they do not assert fit on original Ford spindles. The table’s All/Base entries still require the correct original factory spindle.
What comes in the kit
Red powder-coated Dynapro 6 six-piston calipers, 12.19 x 0.81-inch iron SRP drilled/slotted rotors with black electrocoat, and a BP-10 pad axle set.
The hub kit includes the listed hubs, rotor adapters, mounting brackets, bearing cones, grease seals, spindle washers, dust caps/O-rings, wheel studs and assembly/shim hardware. Check the actual box against the instruction-sheet parts list; caliper/rotor finish options are not all included at once.
Hubs provide 5 x 4.50-inch and 5 x 4.75-inch bolt circles with 1/2-20 studs. Choose the pattern that matches the wheels.
Before it leaves the bench
Some original spindles need the DS-617 anchor-hole drill/tap work and enlargement of the lower spindle/steering-arm hole to 0.50 inch. A qualified machinist should perform required modifications. Disc-spindle applications use the specified spacer/longer upper bolt; bracket orientation depends on steering-arm clearance.
The hub offset moves each wheel 0.19 inch outward. Recheck tire/fender clearance and wheel position on both sides.
Some 15-inch wheels may fit, but diameter alone is insufficient. Use the exact wheel-clearance template and maintain at least 0.080 inch between wheel and caliper everywhere.
Wheel contact surfaces must seat completely on the hub face. Overhanging contact surfaces require separate 300-11961 steel spacers (6.60-inch diameter x 0.20-inch thick). For stamped-steel wheels without overhang, Wilwood recommends separate 300-10716 hub shields (6.15-inch diameter x 0.09-inch thick).
Flexlines are not included and OEM lines will not adapt to these calipers. Wilwood lists separate front line kit 220-7056; verify routing and suspension/steering clearance. Retain suitable OE spindle nuts/nut locks and supply new spindle cotter pins, which are not included.
Check bracket/caliper alignment, full bolt engagement through clinch nuts, bearing adjustment and wheel seating. Have an experienced brake installer confirm the master-cylinder/brake-bias combination, then bleed, bed and test the system before road use. These are traditional non-ABS spindle applications; ABS compatibility is not asserted.
