Big Brakes

[EndlessEight]

Ahh, didn't realize you had an R. Thank you for clarifying.

Negative. To my knowledge, no one is for the rear for the rear because of the electronic rear parking brake. Alcon, Brembo, and Wilwood do not offer any kits that will fit the 2019+ trucks on the rear once they started using the EPB. We've used R1 in the past, and they make a kit, however I've not heard yet about any offerings from them on the 2021+ trucks.

So have folks been powder coating the stock caliper covers to match the big brake kit caliper housing?

This triggers my OCD

So you’re adding braking power to the front only?

Alcon makes a more aggressive rear pad to go with OEM or their rotors for the rear to balance things out. However, IIRC the ABS module on these trucks constantly adjusts proportioning front to rear on these trucks… if not all four corners. @FordTechOne might be able to clarify on that.

I will say my truck with Alcon fronts, and nothing but Alcon rear pads brakes like a m0therfvcker! How it should’ve came from Ford as I find the OE brakes suck A55 to say the least. But that is highly subjective, depending on how the individual drives. My preference should be self evident to that point. I live in the land of 75 to 85 mph speed limits with short offramp’s.

Something that these brake kit manufacturers may not be aware of is that Gen 3s can set DTCs when larger calipers are installed. The Electric Brake Booster doesn’t like the addition fluid volume that is required to apply the pistons, so it thinks there is air trapped in the system. It’s been an issue with the Shelby upfitted trucks with the 6 piston calipers, and I’m not aware of a fix.

Honestly that surprises me. I thought Shelby only installed graphics kits and Shelby emblems anymore....

That’s interesting, most modern kits worth their salt should not increase fluid volume (piston volume). It was my understanding the bigger named manufacturers merely disperse that volume over multiple smaller pistons in order to more evenly apply pressure to the pads.

They would need to powder coat the whole caliper. There isn’t a cover on top of the caliper itself. I’ve previously used G2 or Duplicolor caliper paint and they’ve worked well. I was able to apply without removing the caliper from the vehicle since it’s applied with a brush.

We've had folks do caliper covers as well as paint their calipers with caliper-specific paint as well.

That's correct. The front axle does 70-80% of the vehicle braking.

70-80 before or after the big brake kit? I am just curious how you keep it balanced

See if @FordTechOne can confirm but pretty sure the truck has active proportioning front to rear. Not uncommon on modern ABS systems. Hell my BMW motorcycle had it. I don't believe it's just a set mechanical ratio. I suspect he will state that it was not designed to work with aftermarket kits. However, if the system is monitoring wheel speed... based on my experiences and others, I feel safe for myself and my uses. Also, in this thread or another I pointed out Alcon sells a more aggressive rear pad to fit the OE calipers/rotors. If you don't know, they are no small potatoes in the braking global market and have a significant financial obligation to protect.
