Rust on the rotors. Check em out after it's been parked for a couple of
days .. you get temporary rough spots that don't necessarily go away with
just a few stops. All sorts of strange things can happen.
My S4 did this all the time, luckily it goes away over time and gives you
a better excuse for you to be the one that drives when you have friends
over and wanna go somewhere:
"Lets take my car, I need to get the rust off my rotors before it gets too
On the note of warped rotors- one time I didn't have the time to torque my
wheels to spec when I rotated tires (can't remember why) so I just blasted
them on with an impact. Stupid. Within a day I had a bad warp up front at
highway speed braking. I basically pulled the rotor out of round from
uneven torquing. Surprisingly.. I retorqued all the lugs and it went away
after a few days.
