"(((NO JUDDER, no pulsing?"))) And you are going to get even disc level surfaces on both sides with sanding? Blocks of wood with sandpaper wrapped around it, spin the wheel? Look, ma, a lathe? I took my finger over 13,000 miles of front disc surface. Even the reflection in the garage shows how lined that disc is. Are you about to tell me that a few swipes of a fine grit paper is going to shave that hard surface down a few .001" OF A INCH? I would like to see your 5 minutes of sanding take off even .000001 of surface so it is even with the lowest groove. Lets play deep groove, .00099999" or deeper? Add one more number and there is your .001" deep.
Run-out is .006" That is old phonograph, 33rmp record, warp city you better see how much you NEED to take out that kind of 33rpm pulse coming around to push the pad in, you feel that at the lever pulsing. That is not even close to a 1/4 of that number sanding for a few minutes. I can't even stop a fingernail over a groove at 13k miles on the discs. Can you imagine the sanding that disc receives on each brake setting?
How come on the second bite, the chatter is gone? Maybe you cleaned the disc to the point it won't stop as well. You could not induce chatter. That tells me the brakes are less powerful if the 2 lever hit is softer, I am on less pressure the second time around. Where is that chatter on the initial hard first hit?
If I pull pad, scrub it on the cement, change the surface contact [pick a side to sand, either disc you/pad me] is clean that bite off. Are you not about to, re-bed-inn said disc/pad < Picking which will stop the judder? That says, no bite = Re-bed-in to reintroduce the chatter. Higher are the shock springs and the extension has less compression. Is not 'Chatter,' the deeper you dive? You sure lost bite bye cleaning. It would seem one could out brake you going in the turn. This is where you blew your brake marker, thinking that chatter better show up now. Do you think you may have rolled past the brake marker you always used? As if that smooth second time around no wheel chatter is no longer deep throating some theory?
We there yet, or you still want that apology? Show me how you remain on a pressure squeeze, one is smooth, one chatters. One is one brake grip action, the other not as grip pee an action at the feel... You feel it yet?
