Pull to the left under hard braking
I can't figure this **** out.
I just put on new rotors and pads on the front. I bed them in etc. etc.
Under hard braking I get a pull to the left. After some inspection, its fairly obvious that the LF is working harder than the RF. The wear pattern on the LF rotor is pretty well established, the RF rotor still has some machining marks on it. I change the caliper on the RF with one I had laying around. Same ****.
I bleed the system. 3 times.
I'm about to swap the rotors and pads from side to side and see what happens.
Could this have anything to do with the MC?
Any ideas? ***** bugging the hell out of me.

I suspect cheesy master. On Miatas, proportioning valve only deals with rear lines (if my memory is good for anything).
You're getting different flow (volume) to LF than RF. Change master, and tell us.

Don't think so.
I've been playing so much with my Galant VR-4, that my memory is fuzzy.
Besides, with Miata in the garage, there's nothing to look at.
But, going by manual, the master supplies fluid to LF, RF, and rear. Rear is fed through prop valve. I think the pressure is split only front/rear.
Check your rotors in the rear.
And, swap the master.

Yep.
But, your problem isn't that the rear isn't locking. If that, then I'd look at prop valve.
The problem is uneven pressure distribution. Faulty master (I'm guessing).
Start by replacing it, and not spending time on Internet forums.

Those are top quality race brakes right there.
So I switched pads/rotors from side to side. Now I have a pull to the right. The rotor with not much of a wear pattern on it has a strange yellow hue towards the center.
Wtf?

I would machine the rotors and try some dofferent pads. Also check measure the rotor thickness to confirm that onw rotor is not way thicker than the otheri
What is the wear on the left side like now? Is it starting to wear a little better? One might be beded a little better than the other. Drive it for a but to see if the left will come in. What kind of pads are you running? Report back after a little more driving.
Have a great day,
Jared
