I was having trouble with what seemed to be the front brakes dragging or staying on somewhat. I rebuilt the MC and bought new pads and disks. When I drive the car for several miles it seems to roll freely but after extended driving I get the distinct impression that the brakes seem to be dragging again? I followed the break in procedure for the new pads. I know that new pads take awhile to break in but what is a reasonable amount of time for that to happen? I've heard that some new brake pads are are actually slightly oversize so the break in period would then take longer? In terms of the MC stop bolt....mine is the later TR3 where I believe the stop bolt was discontinued. I added the stop bolt to get better pedal height. Maybe I'm better off removing that stop bolt entirely if that is actually causing brake drag. Why was the stop bolt discontinued? PS. I have removed the guts of the restrictor valve.
