'13 F150 with 13k miles has had a slight vibration in the chassis/steering wheel since around 8k. Vibration only felt during braking on the shy side of moderate pressure from 30 to 15 mph.
Without any troubleshooting. Assumed the rotors weren't true. Didn't measure run-out.
Considered taking in for warranty for them to turn the front rotors. Decided against it. No need or patience for someone to run the pneumatic socket all over the wheel face and tear up whatever it is they possibly can for an issue that's likely to return as the root cause isn't addressed. Additionally the Ford OEM pads dust like mad. The color uniformity from inside of the rotor surface to the outer portion is horrible. Seems only 30% of the pad is contacting the rotor. Avoiding the headache of taking it in to have the same issue occur in the future several thousand miles from now, simply decided to replace the rotors and pads with a better aftermarket option.
Ordered a Power Stop front brake kit. The kit includes a set of cross-drilled and slotted rotors and high performance ceramic pads. Claim less noise and dust than OEM pads with more bite. The slotted and cross drilled is likely overkill for the application, however the setup is value priced. Sourced from Summit Racing free shipping, no tax.
Lubed the guides with synthetic brake grease. Didn't pull the caliper apart to grease the pins. Performed the break in procedure as documented.
Results. The vibration is gone. Brake modulation seems better. No real way to measure. Dust was high initially, but has continued to trail off over the past days. The color uniformity is considerably better indicating a better brake pad contact to the rotor. No noise. Subjectively braking feels better overall.
