[MBZ] OT - Brake Question

[Dave Wakin]

I have a 2001 Yukon XL 4X4 that the wife usually drives. I took a trip to 
the landfill this morning with it and noticed the brake pedal is pulsing 
when I applied the brakes. There is not steering wheel vibration, so I am 
thinking I have a warped rear rotor - does this seem like the probable 
culprit?

Thanks
