I just upgrade the brakes on my 1988, stock d35 with vanco's black magic 15" kit. At the same time, I had the shop replace the MC/booster with a setup from a 1995.
driving around town, I notice virtually no difference. Ok, it really didn't stop terribly, and I did go from 31" to 35" tires, so maybe there is an improvement. the reason I did all this was because on the trails, in 4lo, if I'm going down a hill (or up, and need to back down), the hill + motor idle was often enough to overcome the brakes.
Anyway, I put the truck in 4lo .. on pavement, but just driving straight, and from stop hit the brakes and gas. at around 1200-1500 rpm, not much at all, the truck overcame the brakes.
IS this normal? Is 4lo just too much for my brake setup (I have a ford 8.8 with stock drums in the rear).
I tried bleeding the brakes -- is there any trick to it? I'm terrible with brakes, but pretty sure I did this right -- Put a screw-in reservoir on top of the fill tank on the MC, filled with brake fluid, and Used a pneumatic vacuum-puller -- started with RR, LR, RF, LF. pulled like a quart of fluid.
Other than bringing this back to the shop, anything I can try myself?
