Brake system upgrades?

[CVP33]

Why it should work:

1) Larger caliper dissipates heat better
2) 6 piston vs. 4 piston = more clamping force plus more distributed across the rotor
3) Larger rotor = better cooling, physics of centrifugal forces
4) Larger pads = more clamping area and better heat dissipation
5) Better pads = more aggressive friction
6) Braided lines that come with the kit = more consistent brake pressure and better heat shielding.

I can tell you from running road courses in my Z06 that just the pad material alone can make a world of difference in stopping distance and handling heat.

As for drilled, dimpled and/or slotted rotors? Purely for show unless you plan on going from 100mph to a full stop for 30 min straight attempting to boil your fluid you won’t be generating the temps needed to make use of drilled, dimpled or slotted. They do look cool as hell tho’!

Road test OK... Performance wise, improved but not night and day difference. Brake pads are actually smaller than OEM, that's a surprise...

does this count?

Thanks for the review! I do know the Alcon setup in tests did FAR better than the OEM brakes. Was hoping for similar out of the Wilwoods.

Absolutely……

RULE #1 for brakes and tires - If you can’t smell ‘em and hear ’em then how do you know you’re at the limit?

1) This only applies to repeated braking though. Most Raptor owners looking for a BBK want the single emergency stop from high speeds to be shorter. It's disconcerting to not have ABS kicking in at high sppeds because there is not enough braking force to lock the tire. The larger caliper does nothing for you in this regard.

2) The number of pistons will not change the clamping force by itself. That is determined by the master cylinder size and the combined caliper piston sizes. You can make a single piston claiper have the same force as a 12 piston caliper, it's just a matter of having the same areas in the circles. Bottom line, without changing the master cylinder and possibly the pedal ratios, you will not get significantly more clamping force.

3) It the same diamater rotor. ???

4) Well, you'd think- but as it turns out, nope.

5) Everything is a trade off on pads with the OEM pad being the best jack of all trades. You will give up something going more agressive- cold performance, wet performance, noise, dust, something has to give or else Ford would run that pad too.

6) Minimal at best, but yes there is some benefit there.

Is the "bite" and pedal travel different at all? Is the sponginess improved?

These areas are largely imporoved, responsive and firm pedal feel.

Brake distance reduced for sure but not very much I think. However, no "scientific" tests done on this, just how I feel.

 

[shigman]

None of these setups are supposed to interfere with adaptive cruise or adaptive braking are they? Does the adaptive cruise feel more abrupt when slowing causing the truck to then accelerate because an unexpected bit of extra speed was scrubbed off? I've never fooled around with brakes on anything with adaptive braking.

Didn’t know the Wilwood pads were smaller. That’s a problem. Technically 6 piston calipers should clamp more evenly and effectively than 4. Again if the pad is smaller….that part of physics goes out the window.
