Brake reservoir for disc brake conversion

[Kurlymo0015]

I have an 83 diesel blazer. Swapping a 14 bolt and Dana 60 in right now. I'm about to work on the brake system. I know I will need a proportioning valve to get more pressure to the rear brakes since I have done the disc brake conversion on the 14 bolt. Will I need a larger reservoir for the rear brakes. The reservoir for the rear brakes is significantly smaller than the front brake reservoir. Will I need more fluid for this conversion or will the proportioning valve be sufficient to keep the fluid level high even in hard braking situations?

just swap a k30 master on it and then this unit to dial it in . https://www.summitracing.com/parts/wil-260-11179/overview/

I did this years ago on my k10 with k30 hydroboost swap with 1ton axles. then used an adjustable unit before they had these out . stopped my 38" swampers just fine. loved it .

and I had disk brake swap on the rear .

By the looks of it, the K30 master cylinder is almost identical to my diesel blazer's master cylinder. Is there a difference that you know of? Mine came stock with hydroboost. Looks like all I may need is that valve? Unless the reservoirs are bigger?Thank for the help!!!

From what I can find online it looks like the disc/disc mc has a larger reservoir for the rear breaks. Thanks again.

I had tons of brakes with the drum/disk k30 master and the bias adjuster .

85 k5 blazer 1.18" bore
85 k30 p-up 1.312" bore
these were both 6.2 option trucks with hydroboost I used for reference .
