I have 2012 F150 with 34,000 miles and I noticed a vibration when I apply the brakes. Feels like right front, but I could be wrong.

What should I be looking at with just 34,000 miles?

The rotors look ok; look clean; no deep scoring.

 

Warped rotors.

 

Just replaced rear rotors this evening and pads. Looks like the one was warped a little felt it in the pedal. Saw it on the rotor where it rubbed, no more pulse in pedal.

 

Yep. Warped. Crappy metal. My guy told me about every five years; replaces rotors. Recycled steel can't take the heat from hard braking from 70 plus MPH. Replaced all four rotors and pads (with lifetime warranty on pads.).

In the future, I will bleed off speed and avoid harder braking. Might last six years
