Got a feeling I need to replace the master cylinder in my 2.4S.
Car has been sat for a few months and brake pedal now goes to the floor but no fluid loss from reservoir … can get firmer pedal with a bit of pumping. Happened before and I just bled it all through and that sorted it but there must be a reason so I’m assuming the master cylinder seals are boarder line
So, anyone know if the master cylinder is the same for all 69-73 911’s ?

Re: Master Cylinder
There is a larger diameter bore that Design 911 are good at sending out, saying it fits - it does but makes the pedal very hard! So make sure you order the correct diameter if ordering from them.

Re: Master Cylinder
And don’t forget to bench bleed it before fitting, it will save you pushing all of that air out to the brakes. Apologies if you knew that

Re: Master Cylinder
I looked at both options from D911, I was told do not get the larger size (23mm?) anyway I didn't and all good.
