A few brake questions...

[SRD art]

To this point my 79 g-body brake system is stock. I'm running a mostly stock 5.3 from a 2000 Tahoe and brakes from LS F-bodies converted on my drop spindles using g-body rotors cut down as hubs and some conversion brackets I already have. Out back is an original drum brake 9" Ford being converted to disc. I have the ability to make any custom brackets I need at school.

I've always run stock brakes on all my cars so conversions are new to me. Any input is helpful.


1. I need to buy calipers. The F-bod front ones are just a few bucks more than the rear and are dual piston compared to single on the rears. Anything inherently wrong (or stupid) with running front dual piston calipers on all four wheels?

2. Speedway Motors sells both braided and kevlar brake lines for g-body calipers for cheap cheap. To use their hoses you have to buy hose fittings for the calipers instead of using banjo fittings. Would the early g-body calipers have the same thread as the f-bod?

3. The price comparison is minimal difference. Kevlar is bullet proof, does that mean they'd be better brake hoses too?

4. I think there is a g-body at the local wrecking yard with hydroboost, I'm going Friday to check. There are also plenty of Astro vans too, which seems to be the popular swap. The g-body would be a direct bolt in, Astro requires some fab work. Is there a difference between the two making the newer Astro a better booster?



5. Is the Tahoe power steering pump compatible with both of these HB units?

6. I'm relocating brake hard lines for a cleaner look and to get them plenty clear of the header heat. In the process I had planned on getting a dial type single line proportioning valve like the Speedway or Willwood unit. I'd imagine there is some tuning involved so I thought I'd purchase a brake pressure gauge. I see in Speedway's catalog they have dual gauge kits. Should I have two gauges to compare front to rear? Or is that an unnecessary waste?

7. I was thinking of running a master cylinder for a late 90's Caprice wagon/ Police/ Impala SS with 4 wheel disc option, 1 1/8 bore. Something else I should use instead?

Thanks!
