2003 Supercrew. Truck has started shaking while braking. It is most noteable when slowly applying the brakes at high speed. It is also intermittent as to how bad the shake is.

Shake the wheel a little bit, but mostly feels like the rear end is doing the bouncing/shuddering.

I also notice if I brake harder the shuddering will subside a little. Almost as if the hard braking is putting something back in line for a bit.

Brakes have been done, no change. Any thoughts on what to check next? I was thinking suspension or alignment issue.

 

sounds like warped rotors to me...when is the last time you had your breaks done ??

 

I did the pads about 90 days ago. I will do the rotors and see if there is a change. Thanks.

 

I have the same problem. I have replaced rotors front and back with new pads with no change

 

I recently found out it was my ABS sensor. I took out the sensor and cleaned the magnet off reinstalled and now all is good.
