A bit off topic, but how was the UPR kit to install?

Thanks Lee. The UPR kit was not too bad but definitely not 45 minutes for someone like me. The challenging part was figuring out a line lock schematic because the master cylinders were very different. One had two ports and the other had 3.

How big is the master cylinder bore? If it's 1-1/8" like a lot of those kits, that's way too big for the factory brakes, something like 7/8"-15/16" normally works well.

Yea I think it is larger.. Crapp

Measure your brake pedal. That will tell you your pedal ratio. Then go to any brak mfg website and check their master cylinder chart and it will tell you exactly what size MC to use. If your not sure how to measure it. I can walk you through it, it's not hard. Let me know.

I have a chart somewhere. I just can't remember where I put it. There's actually 2 charts one for a foot brake and one for a hand brake. Chassis shops can tell you. http://www.mpbrakes.com/techtalk/how...ng-pedal-ratio

Thanks for your help. Ok according to the measurement I am at about 4:1 in the pedal ratio. Will adjusting this make up for too large of a master cylinder?
