DDK - Die Deutschen Klassiker

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 ?

Part No.91135501202 says it fits Porsche 911 1968-76, to you sir, genuine one circa £600, alternatives are available

And if you order from Design 911 use this linkhttps://www.design911.co.uk/?utm_source=ddk-for ... ddk-online

Bugger - just done an order there and forgot about this!

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.

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

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