Clutch master cylinder spring

[kevin63]

Anyone got any ideas where to buy a clutch master cylinder spring from, there isn't one in the seal kit and mine has broken into 3 bits, I have managed to find a similar spring that seems to work fine but I am sure I will have to replace it again soon.
The car is a Cerbera but I think most TVRs are the same.

Kev, Can you just remind me what you make for a living?

Clutches, not master cylinder springs unfortunately, clutch is ok, mind you we don't make them for Cerbera's so that might be why it's ok.

If it is the same Girling cylinder as in Chim/Griff the original spring has never been available on it own or in any kit. New Cylinder time.

They know how to make money don't they, I will see how the spring I have made goes on, the pedal feels spot on with that, I suppose if it starts feeling a bit funny or hard to change gear I will have to buy a new master cylinder.

If you know anyone that works on TVRs they must chuck old master cylinders in the bin most weeks, they leak more often than they do springs

I had this problem years ago with a TR6.
I phoned the cylinder maker. The key is to get through to the right person. Most can't be bothered, but there are a few people that are helpful.
When you do you will need all the numbers that are on the cylinder.
I got a guy who was prepaired to take the time to look up every vehicle that my cylinder had ever been fitted to.
He explained that the reason that the spring is always unavailable is that they assume that it broke inside the cylinder and scored the bore. Therefore for safety reasons the spring is never available.
I explained that I dropped the spring and it broke hitting the floor, therefore my cylinder bore was fine. I also explained that I was going on holiday that evening and the only chance of being on the ferry was to get a spring from the breakers yard.
He told me that the most common fitment for that cylinder was as a clutch master cylinder in an Austin 1750 Maxi, so I nipped down the breakers and bought a cylinder.

Thanks for that info, I may be lucky with the damage to the bore, when I took it apart there was no leak at all, but time will tell.

hi i wouldnt bother replacing the seals as you can buy a new master cylinder for twenty something squid!
Also my seals were replaced about 6mths before i brought the car but the first job was replace the master cylinder due to them going again.so imo it just isnt worth it. also glue the bottom bolt into the master cylinder it makes it a lot easier to refit the master cylinder on your own.
cheers ant
