lol @ Raybestos. Thats like asbestos. Which is found in brake pads heh. Did you notice any difference when you put you new rotors on? Also, how do you service the drum brakes on these trucks? Mine are doing that squeal thing now, much as disc brake pads do when it is time for a new set. I am not experienced with drums, im afraid. The only thing i have ever had to do was change a broke spring and i forgot how to even get the drum off. Course i hav not taken a look at it yet.
