I really need to upgrade the cobra brakes. Stock setup isn't cutting it anymore.

I've been seeing posts on FB about using rotors off a newer Mustang. I believe the post said they were 13.2." Anyone went this route?

It's a good mod, mine with the upgraded rears are pretty impressive.
I'm still debating on if I want to go this route or something else like wilwood.

While it's nice to have a setup that's engineered for your car, I always favor replacement parts availability over anything else. The ATS set up can be found everywhere for years to come.

It would be pretty cool to get two Terminators, one with the ATS brakes and another with the 00R brakes and do some back to back testing.

You'd have to use a car with the same wheels and tires, and roughly the same weight and weight distribution as well.

Would be interesting to get some real world data on them though. I would think a simply test would be to use your phone, pull up an accelerometer app and baseline with the stock Cobra brakes. Get up to 60MPH and do a full power stop and see what the max G's pulled during deceleration would be. Then do the same with the ATS setup. Provided your tires are good, and ABS isn't activating, it would be interesting to see if there is a difference.

If your ABS is activating with the stock Cobra brakes, you need better tires, not better brakes.

BTW, got around to finally painting my calipers. Also painting my rear 43's to match.

I'm converting my Fox to hydroboost, so looks like i'll finally get myself into the ATS game after all. Just hoping my new wheels clear without a spacer (I think they will)

Basecoat, apply decal, clearcoat. could prob use a wetsand, but i'm not going to go that crazy here.

what kind of paint?

Duplicolor high temp caliper paint. Real Red plus clearcoat. The decals are just vinyl decals I bought off ebay.


My current calipers were done this way 3 years ago, and have held up fine. All i'm doing is cruising around with an occasional heavy stop. I have no idea if the paint/decal would hold up if being road-raced, or autoXed, but I would imagine a person doing this doesn't care about pretty red calipers anyway.

@Mustang5L5 info on the hydroboost setup. like what size MC, pedal assembly, etc.

I'm using the Max Motorsports kit to adapt a 99-04 Hydroboost unit to a fox. Comes with a new brake pedal for a revised pedal ratio and using the standard 1 1/16" MC like other 99-04's. Basically no different than any other 99-04 hydroboost setup so unfortunately this doesn't help the SN95 guys here much.

I need to pull my dash and rebuild my pedal box with the new arm. I hate pulling dashes, so since i'm already there to replace my A/C evap core, I just do the hydroboost at the same time so I don't have to ever do this again.

Why on a Windsor car? Not ruling out a coyote or termi swap down the road on this car. All depends on which engine I can find a better deal on first. :)


Anyway, i'm planning on the ATS/43mm setup with the 99-04 hydroboost/MC. This should be the same setup as most guys here are running so at least now I can join the party.

I do have my XTS brembos on Ebay….

you got me wanting to change my setup now lol. couple months ago I was thinking about going hydroboost. I was not sure about the MC bore size. My car is currently on stands at the moment I'm boxing in/ reinforcing the torque boxes. Built a new rear end. And doing this brake swap. So I still have some time to think about it.

With the mc size 1 1/8. Do you think you'll have any brake fade/soft/hard/spongy or anything unusual? Or does the MM kit accommodate for that as if it was a 93 Cobra booster, SN95 mc?
Thanks for the info.

It's different because of the revised pedal geometry. You pretty much need to think of vacuum boosted setups and hydroboost setups differently because of this. The pedal geometry can add/reduce pedal stroke simply by moving the pivot point up or down moving more/less fluid with each stroke.

For instance, I ran an 04 Cobra brake setup on my fox. The cobra uses a 1 1/16" bore MC, but on my fox, I was using a 1" bore MC to get proper pedal feel. Apples and oranges really.


96-98 cars and 99-04 cars have different pedal geometry between them as well. The 99-04 setup is improved to help with pedal modulation, but I don't understand the specific differences enough to be any sort of authority on the swap.

So this looks to be the only option for those who feel the ATS/43 setup leaves them with a pedal a bit softer than ideal

It 1 1/8” vs the stock 1.062” (1 1/16”) MC

Gent on FB posted up that he is using it and it feels good. I don’t have details on brake line install for it however. Ports are 3/8-24 inverted flare, while the stock MC uses M10 and M12 bubble flare (and difference sizes depending on ABS or not)

I thought someone found a 1 1/8th ford master cylinder we could use back a few pages in this thread?

Bolt size is an M10-1.0.

It looks like the Dorman 14100 is an M10-1.0 that is 27.5mm (1.08") long. With my Russell banjo block and a couple of copper crush washers, I should get about 0.5" of engagement in to the caliper. I have no idea if that is good or not. The threads on the caliper are about 1.0" deep.

Doesn't look like these come with crush washers. Looks like Dorman 66250 crush washers will work.

Adding info only because I just saw this.

The original ATS banjo bolts are M10 - 1.0 and 27mm in length. That would mean the Dorman 14100 is a direct replacement for the original banjo bolt.
