Anybody know anything about FD brakes? I went through the free bin at the junkyard and found at set of Fd calipers.

from what i can find its basicly the same as the fc caliper just the out side is cast a little thicker other then that it uses the same pads and guts. the mounting points i think were the same also since the adapters for rx7 brakes on a ae86 are the same part for fc and rd calipers

Thanks for the help.

so i grinded down the nub on the face of an fc caliper last night and doesnt look like it had any passages for fluid. next step is to hook it up to a breakline and see if it leaks. if its all good this could make it fit on a few more wheels

I have definitely seen a Miata race car with FD calipers grafted onto it. They were raced at the professional level (I think Grand Am/Motorola Cup level) that were probably built and raced not too long after the Miata first came out. For some reason, them being in SPU class sticks in my mind but it has probably been at least 5 years since I've laid eyes on them in my friend's old SCCA "community" garage.

I have a spare set of FD calipers that I have thought about putting on my Miata. The only issue with using these calipers (as I also own a FD) is that you can't get pads in as many compound types for the backing plate like you can for a Wilwood/AP/etc. caliper but there are plenty for street and track.

I don't remember exactly where the fluid runs through them but I have seen at least one of them that was a parts store rebuild that leaked from where the two halves are joined. The FD service manual mentions that you should not loosen the bridge bolts, so anywhere near that seam is definitely off-limits for modification. I have not had to take one apart that far to rebuild it as I've been able to do replace seals without breaking down the caliper...

Hmm. So, I just need to get bigger brakes for my FD and I'll have a set + spares for the turbo Miata. ;)

So mounting them with those outer housing bolts is not a good idea then?

I rested a a wheel on the caliper/rotor combo yesterday and there is 10mm between the mounting point of the wheel and the rotor hat. So figure a 12mm spacer would probably be the ticket. Keep in mind my wheels are a +40mm offset and have kinda thick spokes.

Well I am wondering cause i know my caliper came off of a 99 RX7 if mine are any different than the US ones.

In for updates.

Project is on hold if not abandoned til I find a job.

I don't wanna pay $1500++ for big brake set up

being DIY and cheap is good too

I wanna see updates and feedbacks!

This isn't going to happen til I can afford new wheels, flares and wheel spacers. In other words, its not going to happen any time soon. There is just no easy way of making this work.

Well I think people doing something similar with FC (modified) hub...

don't remember where....

That would probably work better. I have no idea how those hubs look though.

they look too big and 5 nuts, so you need to have them drilled and tap and balanced...

I'll for the DIY this weekend

I'm going to start playing around with measurements once I get my car apart. I think its time something happened with this.

I have corrado rotors and FD calipers that I will be adapting may be a while I have already had vr6 engined adapted to rx7 trans and installed. It has been a long project hopefully finish this year

Make an intro thread, then pics or ban.

I hate VR6s.
