I finally got Traxxas on the phone. I told him about my issue and they are sending me a new set of pads (kit) as a courtesy. He told me that it's easy to install which involves removal of the old components and reassembly with the new ones then tightening the nut all the way and backing it out 1/4 turn. He also said the 5352R (heavy duty) kit is a good kit if I plan on racing or are in a heavy use situation. I will now have 2 sets of pads and if I find I am going through them too quickly, then I will upgrade to the heavy duty ones.
