Personally, I'd gut the combo valve an then look at a bigger MC. Do some hard braking and see if you need an adjustable valve - if your backs start locking up, you will.

I have jb8 brakes up front - the big Bendix ones which have the same piston area as the 04 fronts I pulled the rear from - so I went w/ an 04 master cyl. Balanced from the factory. And stops well, but was a tight fit...

The van mastercyls are an easier fit, very slightly smaller brake bore (1.3" vs 1.4" I believe) and may be appropriate for your fronts. If you want to come take a look at mine and see what it took to fit that giant 04 in come have a look.

I have to change out the fuel pump tomorrow night then can take it out for some brake checks.

I like this a lot i can get the master for 75 dollars. I probably would just get the adjustable valve so I can really dial it In.
 
I think you need to add a PV either way. The front calipers and lines sizes are still different in your truck versus the one the axle and MS are from.
 
You may need one - but you still have to either gut that factory combo valve or get one of the ones that's already gutted.
Couldn't I just replace it with a adjustable One? By combo valve you mean prop valve right? Just so we are on the same page.
 
Thanks for the links guys, I briefly searched and tried to do it cheap... Looks like I will be gutting it first and then if needed I'll buy the Willwood valve. Or I will just buy it anyway when I do new pads and rotors.
 
With blazer bash coming around the corner I made a list of everything I want to have done... I estimated about $2800 in hard cash... :doah:
 
How many of us run the stock system with fine results.

Not sure why you are even worried about a prop valve, kind of confused ? mine works fine and it is the stock system with rear disc added.
 
No I drive it around town, and drove it to Moab for three years with the same set up, tires smaller but same everything else.

It nose dives on the brakes, weird feel the rear doesn't have much. I would rather dial it in then feel ok about it. Safety is a big concern of mine.


Put about 100 miles on it tonight. I suddenly feel like I need more power but content with it. I have way to much fun hot rodding it around. 300hp to the ground doesn't seem like a lot but it moves... I hear it is though?
 
Been thinking about the interior a lot lately. I Feel the factory dash doesn't have what I need. I want to add multiple 7+ inch displays and have switches and buttons available...

I have thought about the diy4x dash but it doesn't have what I want or the look.

What I have come up with is the factory dash along with something like this. http://www.dirtskum.bigcartel.com/product/99-07-silverado-center-console
Along with two suspension seats, I wanted to keep the bench for hauling my nieces and nephews along but the truck is headed to where a cage and harness is going to be needed....
