Hi guys,

I've booked a 15min window on track at ppc in the park and in preparation I'm
Trying to get a few bug ironed out.
First off brakes: I've got a servo and think I'm not getting grate pressure from
It also the feel isn't great. Do you think both of these points will be improved by going back to a later style dual master cylinder?

Second oil pressure: when I've been driving it around from cold I get mega pressure 80-100psi as the engine warms up pressure drops abit as you would expect to 50-60 but the pressure fluctuates massively with the engine revs when really ho at idle it's down at 20-30 but goes all the way up to 70-80 when I rev it over 4000rpm.
Do you think the min pressure ball and spring thingy is playing up?? And are those addjustable things any good?

Cheers

I prefer yellow tag master cylinder with no servo personally.
I've never had a pedal feel as good with any servo assisted minis I've driven.

But I guess thats all down to preference.

I ditched the servo on mine for the same reason, felt good on the road but didnt give enough feel on the track

those pressure relief ajustable valve after market ones are no good in my book,

stick to the standard set up, the oil pressure is fine, when warm

on the brakes pump the brake pedal with the engine switched off and then start the engine with your foot on it and you will feel the pedal move down a little bit this means the servo is working
