Best Disc Brakes (kit)
What are the best brake kits(or part #'s) that you can get for the 4wd 6 lug 67-72's that will fit into stock 15x8" steel wheels. While Wilwoods look cool, I've heard conflicting statements on their stopping ability for the price tag.
From what I can tell, there doesn't seem to be too many product offerings for performance brakes in a 15" wheel package.

Re: Best Disc Brakes (kit)
While I don't have Wilwoods, I do recall reading that the OEM 1/2 single piston design offers larger surface area than the wilwoods dual piston design. Which is why they don't brake as well as stock calipers.
for 6 lug brakes I'd wager stock calipers are going to be your best bet. For me personally it wasn't going to cut it with my lift and large tires so I went 8 lug 3/4 ton brakes which have a larger rotor and the caliper pistons are slightly larger as well. Then I put on a hydraboost setup. ![]() |

Re: Best Disc Brakes (kit)
Many swap the entire front diff out. Disk brakes started in 71 and Blazer and Suburban half ton diffs can swap up to 91.

Re: Best Disc Brakes (kit)
I made my own from OEM parts. Uses the large late model rotors and late model 4 piston calipers. It all fits in a stock 15” rim also. If you have machining abilities, I can explain how. The brakes work excellent and way superior to the original. The best part is that everything fits on a stock drum brake hub so you can convert an original drum brake front axle to disc . If I recall, I have pics on my build thread.

Re: Best Disc Brakes (kit)
I used 2003 calipers with mid 90's rotors. The backing plates are made from 1/4" plate. Obviously the backing plates need to be custom machined, but also the mounting hole on the rotors needs to be opened up a bit to fit the Blazer hub. Also, to get it to fit in a 15" rim, the bottom of the pads need to be clearanced. I also used a 2003 master cylinder, but planning on changing that out one of these days. the 03 master cylinder has a 1.250" bore, and it make the pedal too hard for my liking. It all works great but I want to go down to a 1.125" bore master. It's an easy swap, but as I said you will need to machine stuff.I have almost 20000 miles on it now and it stops like a late model truck. For liability reasons, I cannot make these to sell.

I've had a lot of PMs requesting info on what I used, so I'm hoping in the next few days to post part numbers of everything. Hopefully the OP won't mind if I do this on his post. |

Re: Best Disc Brakes (kit)
This is the only pic I had of the back plates, but will give you an idea how the calipers mount.

Re: Best Disc Brakes (kit)
I've heard lots of great things about hydroboost. Did you do a thread writeup on your hydroboost system swap? If so, would you be able to include the link in this thread so it can be referenced in the future?
