Gt6 ali brake master cylinder

[RedRooster]

Any ideas where i can get a new 5/8 bore brake master cylinder in ali, the mainstream suppliers just seem to have the plastic versions.
Thanks

Canley Classics do alloy ones. GT6 is usually 0.7" (or 0.75" for late models) not 5/8".

GT6??
5/8 is herald/spifire sized, GT6 should be 0.70 (late ones were 0.75, think they had a servo??)

But I believe the new ones are all plastic, so if you want an all ali one it may take a bit of digging about. Ebay can turn them up, and autojumbles etc. Don't restricy tourself to just Triumph specialists either ;)
Bear in mind that any proper old stock item will need a new seal kit fitting before use......

actually, a peek on the bay finds this one

On ebay i've found these

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350413520364&ssPageName=ADME:X:RTQ:GB:1123

they have the 0.75 bore which Cliftyhanger says is correct for a Mk3 with a servo, however the reservoir size is the same for both, so would the brake one have sufficient capacity?

Those are not Triumph cylinders the reservoir is too small for disc brakes also if using for clutch the reservoir is at the wrong angle.

I could sell you a pile of new cylinders the same as that.

If you have a servo this might be suitable:

If not stick to 0.7" unless you are Mr Universe!

[RedRooster]

Just checked, thats a perfect match, so i'll get one from them, nice site too.
Thanks CharlieB

Got the new master cylinder in this afternoon, its an exact copy of the old one apart from the lid is a slightly smaller size so my bleeding kit doesn't fit. Had an interesting conversation with the missus whilst bleeding every thing apart from the brake, bless her dyslexic little feet  :-/

One set of copybook unblotting instructions required urgently?

Yep, the nylon and metal caps are not interchangeable.

[RedRooster]

I might spray the cap in ali paint so it doesn't look so modern & stand out like a sore thumb, i did try to build up the MS thread with aluminium tape to get the old cap to fit, but it didn't repeatedly work.
