I have noticed at light braking there is a pulse much like when I had warped rotors which have been replaced.
Could this simply be dirty sensors??
No lights and seems worse some times-seems odd.
[I have put in hub centric rings some time ago as after market wheels.]

IF so that is what mine did last week. I took the sensors out they were clean but the copper sleeve and area it sat in was full of corrosion, salt etc. I took the sleeve out round wire brush (like the one used to clean gun barrels (10-12 gauge works great) and clean the area. then I but Dielectric grease on the sensor and copper sleeve and no more issues. that should help.
