advice on fitting seals in front master cyl yam F1

[sandpiper]

hi fitted new seals in front master cyl, but it seems to be pumping back and forth, the kit contained 2 seals, 1 shim washer, 1 spring, 1 plunger, and 1 metel thing that i guess the spring connects on to. can some tell me hoe to assemble all this please properly. i have fitted the two seals on the plunger with the lips pointing inwards in to housing with the washer shim behind the seal furthest in the bore and the metal thing on the end of that seal with the spring located on the end.i will try and upload a pic of the plunger built up.

What model bike is this for? When you fit the plunger inside the housing is it a good fit as in the seals have a slight resistance to them.
Sorry can't offer much more help at the minuite.

Sorry should have read title says F1 to early in morning is my excuse. I'm sure someone here has built up an F1 master and can offer better advise.

It seems to me that you have put back everything in the right.

I had the same issue with my brakes and found out that the repair kit was wrong.
One of the seals had a bigger internal diameter that it should and it did not seal right.

How do you know it is not pumping correctly?

when you pump the brake lever no fluid comes out the hole and if you put your thumb over it and pump there is no pressure or fluid coming out.
