GEN 2 Big Brake Kits

[Bullishone]

Rotors are 2 piece Drilled and slotted 405 MM Front, 380 Rear, 8 Piston Cal front and 6 Piston rear. Comes with SS lines, Pads etc. They will do any color combination you want in either gloss or anodized. Freedom worked with R1 for a direct bolt kit for the 17 Raptor. Build time is 4 weeks, which, is fine waiting on the wheels anyway.

Yep dead on. Looks like I am the 1st or 2nd in so I will give updates on the process.

That's pretty awesome, gotta give Freedom credit for putting it together ... can't wait to see what it looks and drives like.

Yeah from what I was told they put in a lot of work getting the kit speced out etc. if it bolts right on it will be a great option.

I'm sure they checked but their 8p will fit on 20s? Brembo requires 22s.

Are you sure your factory mastercylinder can handle the volume of those calipers? That is a huge change from stock.

Good question on both, I asked Freedom to clarify both for me/us. Once I get a response I will post it. The kit can be a 6 piston and 6 on the rear should the 8 not work.

According to R1, as long as the Rotor size is 380 or 405 the 8 piston will work on the 20" Wheel.

Also they stated the stock master cylinder is more than enough to operate effectively their 8 Piston Caliper.

The answer is yes, they will indeed fit. R1 puts a lot of R&D into their kits and actually offer different size options for different size wheels, up to and including a kit with 6 piston calipers in the front that fits the stock 17" wheels.

The overall volume of the fluid capacity will change, but as long as the fluid is full and properly bled, nothing will change with the pressure from the brake system.

Chinese made brakes, but they seem to have a good reputation for low cost and decent performance.

The amount/volume of fluid required to move a total of 28 pistons is going to be much more than the stock setup. Hopefully you have done your engineering and tested the piston pressure/clamp force at each caliper.
