Ranger Raptor Brakes performance?

[spazzyfry123]

A Ranger Lariat weighs in at around 4500 pounds, the Ranger Raptor weighs in at around 5300 pounds. Can the brakes be the same in both vehicles ? From what I read the Raptor was primarily developed in Australia with help from Ford Performance. Yeah most pickup trucks have crappy brakes. But this is a performance vehicle. And a really cool one. I would find in perplexing why Ford Performance would not update the brakes in the Raptor over the Lariat - or any other Ranger.

Simple and completely lazy research on my part, but out of curiosity I went to *insert auto parts store of your choice* and none of the offerings for brake rotor components have the same part numbers. With it being new, though, I wasn't able to find caliper detail as an example.

Googling around for a little more in depth...

Standard front rotor = 302mm
Raptor front rotor = 341mm (~13% larger)

Standard rear rotor = 308mm
Raptor rear rotor = 332mm (8% larger)

Seems the calipers are the same sized (not sure if actually the same like for like), but they both use 2" twin piston calipers up front and 2.12" single piston rear.

They both use the same electronic brake booster from what I can tell, and they are both suffering from being a part of the 25S77/25V488 recall affecting the EBB. That doesn't necessarily mean that it's rock solid that they are using the same booster as the remedy to the recall is a software update, so my assumption is that the Raptor may have different tuning/calibration but may be retaining the same hardware.

Short of it from what I can see is you get larger rotors and presumably a different calibration with the Raptor, but may otherwise be mechanically the same.

Another major difference is tires. The KO2s are not good handling tires on pavement and the KO3s are hardly better. The Lariat and below come with a road-focused Goodyear AT tire.

I'm 100% certain that the pad/rotor is capable of locking the Raptor tire/wheel on dry pavement so braking force isn't the issue, as you mentioned weight but also grip are the limiting factors.

That's fair too, admittedly I haven't really done any stops with ABS yet so hard to say if my feel is all up to the tires.

I tried yesterday and I'd say the body motions were dramatic with the front dipping then the whole truck rocking when stopped. Definitely wouldn't want to experience it for the first time in an emergency.

I drive a Genesis G70 which is very flat and stable with excellent 354 mm front rotors and 6 piston Brembos so the Ranger's brakes are just adequate, but I wouldn't say bad.

That’s a very good point Dayton

This got me re-looking sources to find the 341mm (13.42in) front rotor diameter, and I found a Ford source for the 2025 RR. Oddly, another Ford source shows the 2024 RR with the 12.24in front rotor.

When I was digging, that was the same source I had pulled, but I was only searching for the '25.

Over an inch in diameter between a '24 and a '25 is a significant change if accurate. All the same, that diameter still larger than a standard Ranger's even if only by ~8mm. I never would have thought that the '24 to '25 difference would be that.

Some sources are incorrect, Raptor have different rotors like I posted earlier and spazzyfry.

Though it can't be much bigger has 17" wheels must fit. Those are not road performance beasts, that is not their purpose.

Go buy a performance sport suv if you want braking performance on the road.

For better initial feel, you can try different pads.

Next you're going to tell me I shouldn't be using this snake oil to lubricate the rotors?

Sorry if I sounded rude, english is not my 1st language at all...

Just saying I don't really see how to quickly improve initial feel you seem to try to get to improve confidence in those brakes.

Aftermarket brake pads can improve initial bites, even if not really improving maximum braking power over OEMs.

Don't know if brake boosting device exists like the ones on throttle pedal.

I'm outta this topic, I'll stop the escalation here.

Could bleed the brakes and see if that helps.
At least 1 guy here said it did.

Lol you're not rude I'm just kidding. Alles gut.

The RR does exhibits less front end dive than I was expecting. Must be due to the Live Valve shocks. Or I am imagining shit as I approach the age of 59...

A point I somewhat glossed over out in my earlier post. The shock/spring settings are undoubtedly setup to be soft on initial compression for off road performance, which makes matters worse on road when under hard braking given they allow more dive. This likely is why most initially find the behavior disconcerting as theres a lot more forward weight shift going on than we're typically used to these days. After a while you get used to it and things don't feel quite so foreign.

I'd be interested to see the shock dyno curves for the different modes. Again, sport mode might improve things a bit, but I've yet to experiment with that in terms of braking.

I watched a video of a RR (white truck) braking hard and it looks identical to my Lariat. Major nose dive. Recall my point of comparison is a sports sedan.

I think we have gained around 40ft or so of improved braking from 60mph when compared to the prior generation Rangers Those were close to 140ft from 60. LOL
