Pads always touch ... If they are binding ... then do 2 or 3 miles without braking and the rotors will be *hot*. Too hot to touch. Have you used coper paste between the pads/the pistons/the caliper? Most likely you have a very simple problem and you should not modify anything the way you were suggesting. If you were to remove friction material from the pad (you may have to do that if your brakes run *hot*) you have to keep the pad perfectly flat. Else you will get a smaller surface of the pad touching the rotor, the rotor will be damaged and braking performance will be much worse. One way of reducing the thickness of the new pads (I will be killed now) would be to use one old and one new pad on each side of the rotor for a few miles, and at some point try replacing the old with the new pads. This is how I used the Lucas pads I mentioned in my other post. I got the fire extinguisher ready. :-) Charles -- Please remove _removeme_ to reply.
