I'm Awesome
Well I think I answered my own question with a quick test.........Drove the truck around the block and with the truck still running and with it not running in park tried it both ways I thought I might see some pressure even a small amount if I cracked the bleeders on the rear disc...........so I opened the bleeder and all it did was dribble out from maybe gravity and certainly not even 1 pound of pressure........I seen no residual pressure at all............so does this answer the question? I also have enough reservoir in the master even though the masters for 2000-2004 have larger reservoirs. I see no reason to change the master cyl. I bought this kit from Lug Nuts 4x4 and he said he has sold thousands of these kits for trucks and has not heard of anyone changing the Master cyl..He also said the tried a test where he added a 10psi residual pressure valve to the rear and said he seen no difference in any part of the braking. So I would say unless you have a bad master cyl leave it alone during this swap. I would think this would show up if you jacked the tire off the ground would you require any real resistance because of those 10psi...as it stands I am sure if any there is almost no residual pressure left in the line.............
This is all good because its one less thing you have to purchase to do this swap......
