thanks for all the help guys. i will try these steps over the weekend.

sub'd

a minor update....I noticed part of my rear rotor wasn't shiny... looked in and the pistons were spun around....and putting pressure on the wrong part of the pad... I sanded the pad down, to get back to square, and put the pistons back in the 30 degree orientation... I think they spun because I don't have boots on..they burnt off on the last track day... so could be boots are necessary...to avoid piston spin

Randy, No need to do the other side if there is no problem there. Now if changing shoes, yes ...to maintain equal "balance".
