Was checking out the wilwood set ups for the bronco. They had some kits called dyna pro for around 800. Anyone know the difference between that kit and the others? Also since most of the braking is done with the front I guess going all out on the front disc setup and going economy on the rear wouldn't be so bad. Anyone know what else is required to convert the front drums to disc brakes? I don't think the wilwood kits have everything needed.
The front Wilwood EB kits actually look to be fairly complete, they even include hoses where most of their kits don't. Their BP-10 pad compound is not my favorite, but okay for a daily-driver type application. Not great for manual brakes IMO, but pretty decent with a solid vacuum assist setup or hydroboost assuming my muscle car experience crosses over into the EB world. What the kits won't include is a new master cylinder, which will need to be sized accordingly based on the effective area of the calipers and the application in question. The front Wilwood SL4/DP6 calipers are 4.80/5.04 square inches respectively, whereas the OE Chevy D52's (2.94") are 6.7 square inches and the Ford calipers (2.88") are 6.5 square inches, so you'll need a smaller bore MC to supply more pressure/less volume as required.
The Wilwood
Dynapro caliper is pretty much their bargain basement 6-piston caliper that they've been leveraging for the past couple of years in the muscle car market as something between their Dynalite and Superlite calipers that can still be squeezed inside 15 inch wheels. The pads are small, the same size that they pair with their 4-piston Dynalite calipers. Rotor diameter and thickness counts for a lot when you're comparing brake capacity, as more thermal mass means lower average operating temperatures. The Dynapro calipers are typically paired with either an 11.75" or 12.19" x .81" rotor, which to be honest, is arguably not an upgrade from the factory 11.72" x 1.20" rotor, but rather a step in the wrong direction IMHO. While certainly better than the factory drums, I wouldn't go out of my way to buy and install the Dynapro kit over an OE disc solution unless that was all the wheels would allow or you just really wanted to go aftermarket.
The 12.88" diameter kits with the Superlite calipers will require 17" wheels minimum and the 14" kits will require 18's, ruling them out for many not interested in running larger diameter wheels...big brakes require big wheels.
I'm just glad they bothered, as I'd rather have more options than less.
