GT vs V6 brakes? there a difference?

the ford dealer parts guy said the GT and V6 have the same brakes all around. Is this true??

the reason i ask is that apparently at 35k miles the front rotor is slightly warped .. dunno why but new take off has ALL the front brake hardware for 200 bucks and the dealer wants 600 installed

Only the rear rotors and pads are the same on GTs and V6s, the fronts are different.
I say buy the kit from newtakeoff.com and install it yourself, although you don't really need to change the calipers.

well if that is true then the dealers people are retarded

so as long as i put the whole GT takeoff rotor caliper pad combo on together it should be ok right?

I believe the only difference in the front is the rotor and the caliper bracket.

Absolutely none. All 2005 through 2008 GTs have the exact same front brake assemblies (rotors, calipers, pads, etc.). Just make sure you connect the brake lines properly and bleed the system. You might wanna take a look at the proper procedure to adjust the caliper pistons before you install the pads (i.e. do not simply push them back, they have to be turned!).

Good luck and keep us posted!

Still impressive that even the V6 has vented rear rotors, you have to spend a ton of money on a new import before you find them standard.

did the same change out last month, Replaced the rotors, after having them turned.[already knew they were good, but a good idea to make sure that they are true as well], replaced the caliper mounting brackets using the same caliper, saving the bleeding process. stops much better!

The calipers don't need to be turned, the rotors do. That means a machine shop will take the rotors and mill them down a few hundreths of an inch (if even that much) to make sure they are not warped at all and are totally true.

ROTORS not calipers.

rotors

Yes even if they were brand new take off. The set i had were laid flat, set there for 14 months, new takes offs, and still had a small bit of warp. Plus with the new turned surface it mates better with the pads. Just my 2 cents, but you dont wash you feet and put back on dirty socks do you?

That's not what he meant!!! The caliper pistons operate on a groove and actually rotate in and out instead of coming straight out like most calipers. So you can't just clamp them in.

Another way you can approach this is to replace the pads and rotors. I just did this to my car... replaced the stock pads and rotors with those I purchased from RotorPro's. Took less than an hour to complete and they look and stop GREAT!!!

Personally, if I'm going to spend any money at all on brakes for this car, I'm going to be replacing the factory garbage. It's definitely one of the weakest links on the car. Before spending $600 for the same crappy stuff, spend $1,000 and get REAL stuff.

I had a pretty well sorted SHO with Wilwoods that saw a lot of track time over the years and I have to say that the Mustang's brakes are a lot better than one might think. I just flogged mine pretty hard at Gingerman Raceway (a 1.8 mile road cource) a couple weeks ago. Gingerman's very hard on brakes, but with SS lines, good fluid, and Hawk Blue pads all around the Mustang's brakes held up very well. Towards the end of the day (about 2 hours of total track time) the front fluid did get a little cooked, but I think some brake cooling ducts will help extend the fluid life for a longer day.

Just my $.02.
