any videos replacing Master clutch cylinder on Griff/Chimp?

I am not sure if its a lot quicker to replace seals in Master Clutch cylinder from inside car or to replace entire cylinder via very awkward looking inner wing hatch - If the latter, are there any help videos known?

Haven't seen any videos, but it's fairly obvious how to get it out, just the 2 bolts you can see. It is a bit awkward and useful to have a helper hold a wrench spanner on one side of the bolt - you can decide how nice you want to be to them, if they get to poke inside the awkward access hatch or be upside down in the footwell.

I had a bit of trouble getting the clevis off the clutch pedal, but in my opinion aside from that it's much easier to take the whole thing out of the car to rebuild it than to try to replace seals in-situ.

thx for reply - I have heard that the hydraulic connector to the Master can shear making it a bigger job?

Rebuilding - is it a matter of removing circlip and simply withdrawing ram into the cabin - not disturbing mounts, hydraulics - maybe not even pedal clevice pin?

thx

Take it out via the kneepad hatch in the engine bay, it shouldn’t take more than 15 minutes, then rebuild it on the bench.

If you need to do the same to the break master cylinder and/or servo then you’ll have to take the whole pedal box out which is a much bigger job

It's not a bad job at all.

Replace the fork and clip on the clutch pedal at the same time.

When refitting, you can hold the bottom bolt onto the master cylinder with a dab of superglue so it doesn't fall out.

When I did mine on the Chimaera some years ago....and 24 hours before Le Mans! I superglued the nuts onto the master cylinder 'flanges' - This allowed me to at least 'start the bolts from the driver's footwell.

A couple of bleeds of the hydraulics, and we were on the 0800 ferry the following morning!

No video but only yesterday I fitted a new TRW clutch master to my 93 Chimaera not being as young and flexible as once was getting the nuts onto the bolts was "interesting" and I feel it this morning! the clevis was fun getting it lined up and no we did not remove the drivers seat. No glue was used to hold the bolts and managed to persuade the lower bolt into place with a screwdriver pushing on the head and got my nephew to hold a spanner on the top bolt and then used my 1/4" drive ratchet and an extension with 1/2" socket onto the bottom bolt while I squeezed myself into the footwell and did put the nuts on and did them up.

Bleeding was pretty straight forwards if one disregards the pipe on my one man bleeder is for modern small bleed nipples so had to improvise by shoving the pipe into a short section of tube I snipped off my Woodside vacuum pump that did fit over the slave bleed nipple although a bit loosely but it worked and we have a working clutch once more.

So it's basic stuff just awkward to reach and get at .................................... at least for the older less flexile of us!

Thanks for that - Are TRW the way to go, rather than Motaclan, other TVR specialists? - Where would I get the Griff cylinders, EFI pump & Filter from?
