Big Brake Kit
Hi everyone new to the forum. I currently have a 2002 Ford Excursion limited v10 with Paxton super charger and 23” lift running 46” Mickey Thompson Baja claws with 20” wheels. I’m torn between the SSBC v8 calipers with turbo slotted rotors (keeps rotor diameter at stock size) OR the Willwood 16” two peice rotors with 6 piston caliper. As the truck sits now it has stop tech slotted and drilled rotors with the extreme brake pad and braided lines in the front and they suck. The truck is so hard to slow down if you need to come to a quick stop. You absolutely must keep a 25-50 foot gap between you and the vehicle in front of you or things get really scary if they come to an abrupt stop. My question is for the price difffent of about $1,500 is the willwood kit going to give me a dramatic increase in braking power of the SSBC kit? Thanks for the help in advance!

i called them both and they both say that there kits are better than the other . So no help there. I don’t think either one give any actual specs on braking force or power.

brake piston area
coefficient of friction for the pads and the same for rotors.
exact diameter of the disks
From you let me know the rolling radius of your tires, put a level at the middle of the hub and measure from down to the ground.
The above info is what we use for brake force calculations.

Rear parachute like at drag races?
One time use each trip, but re-useable.
not many folks with show-type trucks do much daily driving. Looks great, but....

I know and thanks! for the complement. But the owner lives about 45 minutes away from shop and sometimes he likes to bring it home over the weekend or we take it to shows that can sometimes be a few hours away. It amazes me at how many people will pull out in front of or turn off last minute in front of such a large vehicle.

Let's do some math!!! My favorite subject. What you are asking is something I do for a living. Need the following info from the manufacturer....
brake piston area
coefficient of friction for the pads and the same for rotors.
exact diameter of the disks

The manufacturer will be able to provide this if they are worth buying from, which both companies you mentioned are. They won't tell you what their pad material is, as it is usually proprietary, but they should be able to provide you with the Coefficient of Friction for the pads and the rotors they are including in the kit. Heavy trucks (tractor trailers, dump trucks, etc.) are required to have this marked on the pad or shoe edge, although it is usually not visible after the first couple of days of use. The piston area is also something the manufacturer should be able to tell you. If they can't or won't provide you that info, I would not buy from them. Of all the systems on any vehicle, brakes are number 1 on the list of must be perfect. Your rig is really awesome, but you are asking a lot of the stock brakes. Knowing you have this issue and still driving it is not the best idea. Please get this fixed before you drive it on the road again, my mini van driving wife and my 19 month old baby in the back seat will thank you.
calculations are going to assume your master cylinder is in good shape, brake lines are not bulging and system is bled properly.

I'm not a brake expert by any means, but I'm pretty sure the Wilwood setup with the larger diameter rotors will provide better stopping power. You will need at least 20" wheels to have room for them.
What gears are you running with a V-10 and 46" tires? Just curious what sort of effective ratio you are dealing with. And how much boost is the Paxton giving you?
