So about a year ago a set of pads on the left front wore out early (all the other 3 wheels were at least 50% remaining). Had the rotor turned and replaced all the pads. Later...We were towing the TT and had to panic stop. First, this Expy stopped GREAT! Straight as an arrow even with the 5000# TT. Unfortunately, the left front rotor warped.

Anything about the brake system that would preclude me from replacing both front rotors and pads vs doing all 4 wheels. I've done brakes, replaced rotors and calipers so I know my way around.

Anything different about the 2010 Expy system?

We have the HD tow pkg. Are the rotors/pads the same as a std Expy?

I'm doing it myself as the initial job when I had the scratched rotor turn was done by my local shop as I figured the warranty wouldn't cover it. The turned /warped rotor is surely not covered then.

 

What you have is uneven pad material deposit-not a warped rotor. The rotor/pad got very hot and deposited pad material unevenly to the rotor. It's common. Same brakes rotors on non tow package. I would buy new rotor(turning them is an option, but it's just easier/less hassle to buy a good aftermarket rotor-$50 or so) and ceramic pads for the front and be done with it. You are not stuck with Moto rotors/pads, they are ok, but not great.

 

Rotors and pads will be in tomorrow. Thanks for the info.
