New rotor new pads. Fine for a day then started pulsing again.

 

Probably something to do with ABS. Is the ABS or brake light on?

 

No light.

 

what model year and engine?
Its this a high speed brake shake or does it happen at slow speeds only?


If its the latter, is the abs pump activating? if yes, you have a false activation from a wss signal fallout.

 

03 suburban... 5.3. A little bit of pulse at slow speeds. Really bad at high speed

 

is the pulse felt in the steering wheel or brake pedal?
did you replace front or rear rotors?

 

mostly in the pedal. some in the steering wheel. I replaced the rear rotor

 

replace the front rotors

 

Was wondering if replacing the front rotors did any good? I am having the same problem with my 03' Tahoe

 

I cleaned and lubed the pins. Seems to have fixed the problem.
