Ray, it might be time for new rotors depending on how deep those pits are. Those are pretty fierce. But run them and if you see holes after running... you know they are trashed. Thin rotors means noisy braking; and pits accelerate the wear of the rotors.
Next time you store rotors, drums, exposed gears, or flywheels take a rattle can of paint and give them a good going over. The cheap rattle can paint will wash off with some gasoline (or acetone) when you are ready to install.

Ray I'm with Qingdao on the rotors. If you have new pads on there, its a waste of the pads. You will shorten their life significantly and also mess up the transfer of pad material onto the rotor which is key to the performance of the brakes. See, when the pads are applied they don't just clamp the rotor to slow down the car. Thats one part of it, the pads also deposit a layer of their own material on the rotor surface. This layer acts as a conduit to help convert the mechanical energy when stopping to heat when the pads are applied.
If I were you, I would devise some way to spin the rotors on the car and take some emory cloth or sand paper lightly on each rotor surface until its clear of rust. Kind of a backyard rotor resurfacing. I bet you could write it up in a thread on here and cause all manner of excitement.

It would be a shame to put a lot of effort in the brakes if the motor never runs!!
and since I know the group of old farts that put it together, I can say that

Robert, you are sounding like the Rotary God we know you are.
Those rotors are actually so rusted to the pads that the hub is no longer spinning,
But since you said so Robert, and the Rotary Gods agree, I'll follow your advice.
I'll just slap the wheels on there and go. (Getting the Falken sneakers mounted on the LE wheels tomorrow).
James and Tim are talking like Republicans.
"Dude, you got a problem that needs to be fixed really bad.
I got some Snake Oil that's guaranteed to work.
Wanna buy some?"
I told those guys this is an LE with the FBRAT system, but they didn't listen.
FBRAT was designed by the early '80's Mazda Engineers, it fixes any problems that can possibly arise in front rotors.
You can't get it in modern cars.
Basically with FBRAT installed, you will never need to think about a front rotor again, much less have it turned or replaced.
I'll post pics, here's the before:
After pics coming this weekend when Robert and Mike come over to start up the TW12A.

Tim I read on a social media site someplace that the TW12A startup is going to happen on November 5th, but with all the Fake News coming out of the White House these days it would be best to confirm the date with Reliable Sources.
Mike, Robert, you guys got any reliable info on this?
Yup the FBRAT and it's companion technologies the Beehive and OCD were the ground breaking innovations that distinguished the 1983 LE from earlier S2 FB's and S1 SA's.
Mazda was prepared to introduce these wonders into the entire RX-7 lineup in 1984 but the plan was subverted by the Reagan Administration, which colluded with the Japanese government to impose tariffs on FBRAT, Beehives and OCD so that RX-7's wouldn't undercut the American sports car market (Beehives and OCDs were allowed for another two years).
Of course we know what happened next, the devolved S3's arrived in 1984 with boring interiors, EFI nippled 13B's and retrograde FMOCs, forever tarnishing the FB brand.
In 1986 the S4 FC replaced the SA/FB lineage and the rapid decline of the RX-7 mark was underway, never to recover, left to die with the perversely conceived RX-8.
So History leaves the 1983 LE, with it's elegant and practical FBRAT, Beehive and OCD systems, at the pinnacle of sports car supremacy for all time.
But fear not Tim, the early SA's still have their place in history as the Rotary Rocket that started it all in March 1978.

Ray... always such a downer on the FC.. but have you ever owned one...?
The 2nd gen is a raw enough car as it is, I can't imagine dailying an RX-7 with even less refinement and safety than an FC. Before you ask...No, I haven't owned a first gen. But I have driven enough of them to know that while it's still a good car, it's certainly not for me. The steering is too vague, the suspension can't cope with much before getting all sorts of spine shattering, it's too noisy to drive, the interior feels cramped, and the brakes are awful.
Seeing as the 2nd generation addressed most all of these (personal) concerns, how is the 1st generation so superior...?
It all comes down to personal preference in the end. I firmly believe that FC is a better car overall.
I dunno, maybe I should keep my opinion to myself but can't. Hm... sounds familiar..

Collin I wasn't talking about your FC, I was just talking about all the other FC's.
From what I know about the love and care you give your Wankels, I'm confident your FC is every bit as good as many SA's and FB's.
Maybe even superior to some in terms of safety, thanks for pointing this out.

I see your point Collin.
I think it must be a generational thing.
You know, 1st genners just see things differently than 2nd genners?
I wonder what 3rd genners think?

Collin, you're too young to be obsolete.
Not that being obsolete these days is a bad thing, with the way things are going.
Your passionate defense of the FC got me interested in these cars, which up to now my curiosity couldn't get past the sheet metal.
Turns out the Mazda engineers were still creating amazing innovations in those S4's, despite Reagan's attempt to turn the RX-7 into a Ford Thunderbird.
For example, the Mazda Engineers wanted the FC to have four wheel steering to improve handling.
That didn't work out but they did introduce this thing called "Triaxial Floating Hub (TFH)" or "Dynamic Tacking System Suspension (DTSS)", which causes the FC rear wheels to steer into a turn at high speed, and out of a turn at low speed.
Right up there with FBRAT and OCD in my opinion.
Here's a quote about the suspension innovations, read the full article at:
https://www.conceptcarz.com/vehicle/...azda-RX-7.aspx
"Jiro Maebayshi was tasked with designing the suspension. The resulting mechanics was borrowed from a truck suspension created by Takao Kijima. The front and rear suspension were independent with the front incorporating McPherson struts. To make the car more maneuverable, four wheel steering was experimented with but unfortunately the results were not promising. Instead a system was adopted that allowed a small degree of rear steer to be created by the rear suspension during cornering. The rear wheels would steer in the same direction as the front increasing stability at high speeds. At low speeds the rear wheels would steer in the opposite direction of the front wheels. The system was dubbed the 'Dynamic Tracking System Suspension' and 'Triaxial Floating Hub'. The system did increase noise so to compensate the final drive system and rear suspension were mounted separately on the rear subframe. To reduce the noise caused by the subframe and the chassis, Rubber bushings were used. The rack-and-pinion steering and the updated suspension addressed the major pitfall of the first generation RX-7."

As a 2nd genner, I want to continue to stick FC parts on your FB (like those strut tower covers, remember that? haha)

Dudes, you totally don't understand what I'm saying and misrepresent my perspective.
I'm not "ragging" on FC's and FD's or in any other way criticizing these fine automobiles.
I even think RX-8's can be a sensible option for a family car, if you don't mind the back doors.
These newer generation rotary powered "sports cars" have some good points, I agree.
For example, I agree with Collin on the safety thing, the FC is by far the best RX-7 you can get for driving into a brick wall.
And Brett is right about the FD, if it's unscheduled urination events you're looking for, the FD is your ticket.
I'm just saying when it comes to sports car excellence, judged by the standard criteria of technological sophistication, driving exuberance and sexy good looks, the 1983 RX-7 is the best rotary powered sports car of all time.
I'm not making this up, it's common knowledge.
(Just like it's common knowledge that Donald Trump didn't collude with the Russian's to use social media and fake news to manipulate an uneducated American electorate into voting for him).
Here's proof: Pull an SA, an FB, an 83 LE, an FC, an FD and an RX-8 up to the gas pumps at a gas station.
Watch which car everyone else at the gas station gathers around.
It will be the 1983 LE of course.

Ray is the start-up on for Sunday?
Sounds like a good excuse for a drive in the 7.....

Howdy Greg!
Yep it's Official, Sunday November 5 at high noon is the start up date for the TW12A.
A fine day for a 1st gen drive for sure, the weather is looking excellent for Jefferson, 77 degrees, 20% chance of rain:
https://weather.com/weather/weekend/l/30549:4:US
Robert is coming over from Alabama to make sure everything goes as planned.
We hope to see you and your pretty GS!
All others are welcome too, especially SA's and FB's, lunch will be served.
In the mean time I'm prettying up the LE, redoing the loose side trim, giving her a bath, blah blah blah.
I also mounted the new Falken Azenis sneakers on the refinished LE wheels today, very pretty.
Also I checked the FSM for the FBRAT procedure, turns out you don't need to have the front wheels on the ground to do this.
Just turn the ignition key to "ACC", then give the hub a bunch of spins as specified in the FSM and the FBRAT does its thing.
So I put the key in the ignition, turned it to ACC, mounted a spare X wheel and gave it a spin.
Here's the rusty rotor before:
And here's the FBRAT modified rotor, same one that was locked up yesterday:
Worked great, ready for the road.
I'll post pics of the refinished and mounted LE wheels tomorrow after I finish up the corn starch treatment on the center caps.
See you guys Sunday!
PS, Brett, I have a nice pair of black rubber FC strut tower covers for sale, OGTA discount applies.

Why all the draw throughs out there... So much cooler (I mean that almost literally) to blow through.
Regardless nice "mango" car.
Is that a 997 in the background?
