Anyone know where I can buy a set of seals for the front caliper on my 2004 pro?

I could'nt get just seals on their own, They come as a full overhaul kit (4 pistons & 4 seals) price about £27.
Trials and Tribulations have them.

you should be able to buy the o rings on there own for the pistons i am not sure of the part number for the gasgas but i am sure you could get the part numbers from a gasgas user manual failing that you could allways buy a oring set for about 6 7 squid and there might be the right size in there.

Thanks for that.
I've done a bit more searching and discovered Trials UK do just the seals for £18.27 (they're not listed on the website though).
That's for the earlier Hebo calliper, rather than the AJP fitted to later bikes. It turns out I bought a 2002 bike, not a 2004, which is slightly disappointing....
