Thanks for all the input and I suppose I do not need to " reinvent the wheel ", so to speak. A space in my home garage just opened up, so I can get 142 up high enough to check it out under cover.
You are correct that the existing brakes are top notch when operating properly. I did acquire the Motive bleeder from I P D last year,but will flush and keep the non-silicone fluid in system. I have been looking at boosters in the U-Pull, keeping it vovo prob. a good thing. Your tip make sense as I do need to go thru the old girl, as we have to w/ all of these prized "acquisitions".
I believe replacing the Brake Hoses would help equalize the brakes as well, along w/ the other suggestions. I have had several 140's over the years, but they were newer, I was much younger and never had to perform major surgery on 'em.
Thanks for the advice. you guys motivate me to get busy in the New Year.

Best Regards from Balmy Florida. Kayo
