Has anyone removed and overhauled the master cylinder on a 3.2? It looks fairly straightforward in Haynes for the 3.0. If so any issues and are seal kits available for them?

[Lazydocker]

Normally pretty bulletproof... Has yours gone?

Yep fairly easy to remove, but if needing to remove the brake pedal, and I think you do(?) then acquire a good replacement brake light switch first, as the tangs almost always break off on removal. Very very Brital

Not gone Paul, but the Elite pedal has always been a bit soft compared to the TD, despite fluid change, brake bleeding etc. So i thought I would replace all the seals in the system, hoping for an improvement.

Sorry should of said, I have removed one. I have not opened one up in any way.

Could that be servo/vacuum related?

Hmm, how can I test for that?

First question might be, is there a leak in the vac pipe? Especially where the clip holds the vac pipe away from the air con pipe by the scuttle drain.

They are known to wear through if the clip brakes or hoes missing as the two rub together.

I'll have a look, but as it's vac. it may be difficult to spot, unless a clip is missing

Ideally needs removal and examining, but it will likely hiss with engine running.

The master cylinder or vac pipe?

No, vac pipe.

Does the pedal sink at stand still on tickover?

[Shackeng]

Can't remember, I think yes, but will check. Is this a good or bad sign?

Might be a vac leak in the plenum to servo pipe. Might be servo diaphram (?thingy) leaking inside the servo itself.

But servo pipe is quite common to chaif through and leak.
