2.0T How many pistons are in the front brakes of the 2.0T?

[SFM]

I've searched everywhere, and I couldn't find an answer except that the Brembo brakes have 4 pistons on the front. I assume the 2.0 brakes have 2 pistons? What would be a way to find out?

2.0 uses a common style of caliper you would find on 98% of cars. Single piston but larger. And centered on the pad

Do all cars with a single piston have a large piston? Or on other cheaper cars, for example, it's still a single piston but smaller? The front rotors on the 2.0T are vented also.

venting in the center is modern design. rears are usually single layer. single large piston is also normal. large is relative to the caliper. the brembo vs 2.0 caliper main difference is diameter of the rotor (for heat dissipation ability) and brake pad contact area (for increased grab ability). the caliper then adds multiple pistons to increase clamping power. the main thing in brembo is pistons on both pads. the 2.0 pushes one pad and the other clamps. on the brembos it pushes both pads inward to stop the rotor.

Brake design is a series of trade-offs. Everything modern is quite good, just usually built-for-purpose.
e.g., some rear rotors are solid, some are vented. Just depends on the thermal design and analysis performed by the OEM. Solid is cheaper to manufacture. I was surprised that some really heavy stuff (full size SUVs and cars) from Ford still use solid rear rotos.

Traditional(*) floating calipers typically have one or two pistons located on one side of the caliper. Both are perfectly fine. Usually you see manufacturers move towards more pistons for higher performance (or just higher price) cars. One funny note was Volvo. They didn't design their 2 piston caliper correctly, so that brake system made lots of noise. So they actually switched *back* to a single piston.

The size of the piston, size of the pad, size of the rotor, and dozens of other details, are all tweaked by the OEM to match the vehicle. It all just depends. Generally larger/faster vehicles have physically larger brakes.

Want to know what's on yours? Take off a wheel, take off a caliper and look. 10 minutes, tops.

(*) Fun fact: the first U.S. disc brakes used fixed calipers, back in the 60's, with 4 pistons. Just like modern brembos! Manufacturing at the time wasn't good enough - caliper bodies flexed and the joints leaked, hence why every manufacturer quickly switched to floating calipers, which continue to be dominant.

Great info! Looks like a GT2 will be my next car in the coming years.

The 2.0T has 345mm front & 330mm rear, both ventilated.
The 3.3T has 350mm & 340mm. Not a huge difference if you ask me, taking into account the difference in total mass.

I think the 2.0T has 320mm front and 315mm rear or 12.6 inches and 12.4 inches compared to the 350mm and 340mm or 13.8 and 13.4 for the Brembos.

Nice info! Even though the 2.0T brakes are smaller than the Brembos in every way, I keep staring at them sometimes for some odd reason lol.

I am actually not sure about the 3.3T but I can tell you 100% that my 2019 2.0T GT-Line has 345mm front and 330mm rear, both ventilated. I already changed the fronts one time.
Maybe they are larger on the european models? No idea.

For the 3.3T it's correct, 350mm and 340mm is pretty close to 13.8 and 13.4. For my GT-Line, I haven't actually measured it I just looked at a couple of websites on Google.

It is indeed a single-piston caliper with 320mm Front rotors.

Are you sure? So we have larger brakes in Europe? Strange..

So in some 2.0 Stingers, the size is different?

So, here are the OEM codes for my car:
Front Brake Disc (345mm): 51712J5250
Rear Brake Disc (330mm): 58411J5250
