Brief Description:  Brake MC-4 mod

So I've been experiencing some really nasty brake drag lately that has me really concerned. Everyone has their own theories about what's causing it but I've noticed a small 1/16" slop in the MC-4 master cylinders at the very end of their travel limits that was NOT there when they were new so I suspect a weak internal spring. Interesting enough, I've read on the RV Forums that several other MC-4 users are having the same problem and using an external spring to assist in extending the cylinder completely. A few pics online gave me the idea and with the help of Ace Hardware and the Home Depot, I've now got positive full extension of the cylinders. I'm going to fly her like this and see if it solves the problem. I'm confident it will.
