2011 Ford Mustang GT 5.0: Has Brembos, SINGLE Piston Sliding Rear Calipers

January 19, 2011

This is a screencap from the Ford website. It says the same thing on our window sticker and it says the same thing in every press kit and vehicle specifications page we've seen. The Brembo Brake Package ($1,695) gets you 19-by-9.0 Dark Stainless wheels, Unique ESC tuning and a Brembo Brake Package. This includes 14"Brembo rotors with four-piston fixed calipers and 11.8"rotors with two piston calipers in back.

Trouble is....this Mustang GT (just like the Convertible we tested earlier ) with the Brembo package has single piston rear calipers.

Reader cz_75 called us out on our Ford Mustang GT 5.0 Convertible Track Tested saying, "The rear brakes do have sliding calipers, but they have TWO pistons, not one."Sure enough, the specs say two, but our data sheet, which we compile ourselves, said one.

I scolded the guy who made the sheet and changed the data to reflect the spec chart. When we got our long-term Mustang GT in, I supervised the brake inspection.

"How many pistons."

"One."came the muffled response from under the car.

"how many?"


"Try again. How many?"

"One. Go look."


So a couple of got dirty to check it out. Sure enough, the spec chart was wrong and our car, like the 2011 Ford Mustang GT500, has single piston sliders.

(sorry for the photo, we'll get wheel-off shots soon. Below is one from the GT500 which has the Brembos. )


We called Ford from the track to find out what was going on. Told them we'd bought the car off a lot and that it was not a press vehicle or any other sort of pre-production / tuner vehicle.

A few hours (an eternity for a response from a PR rep) we got a call back that the 2011 Ford Mustang GT with the Brembo package does have SINGLE piston sliding rear calipers and not the two-piston ones as advertised.

Media and consumer information is set to be changed as soon as is possible. Expect some pissed off Mustang owners.
