A rotor or disc on the Ford F150's braking system can become scratched or worn down over time, or it may develop deep grooves if you drove it with bad brake pads. You need to replace a scratched, grooved or worn down rotor. The F150 does use disc brakes on all four wheels, so you may need to change a rotor on either the front or rear wheels. The exact method of changing might vary on older models of the F150 (ones made prior to 1997)
Instructions
- 1
Raise the F150 on either the front or rear end and support it on jack stands. Remove the wheel for the brake disc that needs replacing.
2Unbolt and remove the brake caliper with a wrench and make sure the caliper doesn't hang by its hose (hanging it with a strong wire is best). If you are working on a front wheel/disc, unbolt and remove the caliper mounting bracket from the disc.
3Remove the grease cap, wheel bearing and spindle nuts and the outer wheel bearing with its washer; all this is only needed for a front disc on a two-wheel drive model.
4Slip the brake rotor off of the axle studs.
5Slip the new brake rotor onto the axle studs. It may help to temporarily thread the wheel's lug nuts onto a few of the studs to hold the rotor in place.
6Reconnect the grease cap, wheel bearing and spindle nuts, outer wheel bearing with its washer and caliper mounting bracket if you have changed a 2WD front disc. Reconnect the brake caliper with its bolts.
7Remove the lug nuts from the rotor if you placed them there, then reconnect the wheel and lower the truck.
