@Reddtarga - mine is an early 90 Fat Booster which, according to @5sgte, will take a later 15/16" M/C. 
 
 Yesterday I bled the brakes, and the clutch while I was at it. Some bubbles and both pedals came up a bit which is most welcome. For a minute I thought maybe I don't need a new M/C, but then remembered that the pedal v. slowly depresses over time.
 One thing I want to ask about, is the rear callipers and the handbrake mechanism. I thought the mechanism was self adjusting, and it may be, but I have play. If I leave the handbrake on a click or 2, no effect on the car gently rolling, then 1 pump and the pedal is up much higher, where it should be all the time.
 I greased up that mechanism a few hundred kms ago so I'm not sure what's going on.  
The only thing I can think of is the piston seals have swollen a little (after I used the wrong dot4) and maybe that
is causing the piston (and handbrake mechanism) to retract a little ?? I have new seals coming this week so will revisit the handbrake mechanism.  (Ultimately the wrong dot may have swollen/ruined the MC seals as well).
Front callipers already done.
 
 Oh and I have concerns about the ABS module. I get intermittent pulling under brakes, and maybe I need to investigate that further. It may only when I brake hard and not with normal braking - must verify.
While I am happy to get rid of the ABS, my young son doesn't like the idea. I had some bad experiences with ABS in Falcons mid-90s and the MR2 is 5 yrs older. Does anyone know if the later , presumably better, ABS modules can be fitted to a 90T, now forever known as the "Fat Booster"?
 

Thanks @Reddtarga, I have pumped the pedal with the handbrake on and off, and yet I still find
I get a clear improvement in pedal travel by using the handbrake to put the pads closer to the rotors.
Anyway I'll investigate when the callipers are off next week.
 
re the ABS, yes your advice is sound, but I'm not sure that my unit is not all gummed up, which may cause the pulling. Nor do I know how to tell, but I read in the US, you send it away for pressure cleaning and $$$$ and it comes back working fine. Cause I'm a hundred years old and have ridden motorbikes in the wet for years, and have had some disappointments with early ABS, I'd be happy to run without it. But as you mentioned, I do have wide wheels with wrong offset etc which if changed, might minimise any/all ABS behaviours.

@5sgte - right I missed that. I failed comprehension at school too.
I need to recheck some facts before deciding.
I'd like to go 15/16" but maybe there isn't one for ABS and the Fat Booster.....
 

Too late -

I knew driving without any brakes was not a good idea.

No brakes could have avoided, maybe F1. Trouble with MR2s is that people don't see you behind other cars.
Car in front of me turned left, so another car, in that street, came out in front of me.
Still drivable.

His insurer has already accepted that he is at fault, but this morning a young repairer/assessor started talking "write-off" and if so, I'm pretty sure the insurer will offer some trifle as "market value'.

Some crappy NAs sell for as little a $3k and I think that was the 1st thought. Once they realise the car is $10-15k
I think it won't be a write-off. Fingers crossed - I don't really want to use a solicitor to fight some ridiculous valuation.
I presume I would need a solicitor...

Hopefully that is the worst result.  I would prefer a phone call ""Your car is ready".
I still fear a haggle over market value.
