500 Alpino front brake m/c seals

[Laverdaton]

more problems for the little 500........
When I got the bike, the front brake m/c seals & piston were stuck in - I removed them by using a pin punch to push them out ( removed the front brake lever).
I put the new Brembo seal / piston assembly in over the weekend but the spring in the kit is so strong that the only way I could keep the piston assy in was to fit the brake lever. That doesn't seem right to me......what am I doing wrong?

There's a crush washer to hold the piston assembly in place against the return spring pressure. It needs driving into the end of the m/c where it grips the bore. The trick is to hit it hard enough to grip, but not too hard to bind the piston.

I wasn't sure about doing that - I realise now that I can't have been applying enough force. Thanks, Andy
