BIG Brake Setup For My Truck

Postby Fred » Sat Aug 31, 2013 2:33 am

I think I've settled on a brake setup for the front of my truck. I already have a suitable rear end for it that I need to adapt and fit up. But I'd not put a lot of thought into the front, except dreaming of AP calipers, until now.

My current plan is to get a pair of FD RX7 front calipers from the harder-core variant with the 314x32mm rotors. On top of that, I'll also need to get the rotors, and have some new hubs turned up out of chromoly or something like that.

The calipers I'm planning to pick up look like this:

"The Type RS had a brake upgrade by increasing rotor diameter front and rear to 314 mm (12.4 in) and front rotor thickness from 22 mm (0.9 in) to 32 mm (1.3 in)."

Rotors for these cars seem harder than normal to find? DBA don't list anything as far as I can tell.

The rear axle I have is from a bongo friendee van and has decent sized rotors on it. I really need to pick up a set of rims first so I can ensure the diff is the right width and new tyres/wheels will clear chassis and edge of deck.

The Nissan sumitomo calipers have bigger pistons than the Mazda items, FC and FD Are only different visually, same unit. 300zx, gtst, 200sx turbo etc... I think they mount the same though...

Thanks! The above ones are "special" from the specced up cars, and different to the ones from most FDs. The FCs have much smaller rotors, sure they're the same calipers? I'll look into the Nissan ones too, then. But I'll have to grind off the Nissan badge, it just wouldn't be right ;-)

I agree, we used the Nissan ones in this http://www.trademe.co.nz/motors/used-ca ... 408236.htm - he didn't grind it off though... sad. I have Both sets of calipers, piston size is the same. My FD is a Type-RB, wonder if it counts as the specced up one? Might do some homework, probably only a rotor size increase anyway. What about a used set of Brembo's? BTW I meant I think the Mazda and Nissan calipers have the same mounting.

The only info I've found regarding "Big brakes" on an FD is for the limited edition models - RS, RZ and Spirit R models and looks to be only a 20mm bigger Brake rotor.

Yeah, that's right, and I want that extra size. I don't want to go under 300mm and if you saw how I drove, you'd understand why. The diameter isn't the only thing, they're 32mm thick, which is another requirement. IE, I don't want less than 300x30 on it. 314x32 meets that requirement, 294x22 does not, not even close, mostly due to thickness.

To some extent calipers are matched to rotor diameter. Are you telling me that the two different FD models use the same profile calipers with just different spacing in between? How thick/large are the Nissan rotors?

I'd consider Evo brakes, but they're double the price, usually, and I prefer plain to gold bling.

Thoughts?

That'd be OK @ 296 x 32 but I don't need the rears (at least, not right now).

The FC - FD calipers use the same pads and overhaul kit, I can only assume they space them differently to accept a wider disc. I use FC 4 piston front calipers on the rear of the my RX7 (1030kg), gives you an idea of the stopping power it has. The Evo brembo stuff is usually red.
