[QUOTE=TT;842989535]Does the brake master need changing to one from later model?
I recall reading about pedal feel differences on flying miata somewhere depending on which master was used[/QUOTE]
So i got out and started bedding in the brakes, getting reasonable pedal feel but requires a fair bit to lock up the fronts. Some of that is probably that the pads need bedding in more, and some is probably that they need some brake bias love.
I did pick up an NB8B booster which is bigger and allows for different masters to be mounted, as well as a 15/16″ NB master. I also have a 1″ 929 master on the way from the US before the GST thing hits. With those it shouldnt be too bad to test different setups.
However, one thing i noticed was that the brake bias is very heavily front weighted, as evident from the bedding pattern.

While some people muck around with grabbing bias valves out of 929s and RX7s and stuff, I think in the end ill just use the Wilwood bias valve that was in my AE86 before it went to pedal box. There is a convenient brake union that can be removed to fit it neatly.
As well when i was looking around at bias valve stuff, i found this setup:

Seems the guy with this one has put a Wilwood remote cable on the end of the bias valve and operating it in cabin. Will have to setup the lines so that this is an option down the track.
For now though, time to wait for the 1″ master and move on to other things.
