I'm trying to bleed the brakes in my GT 200. I've got a one way valve attached to bleed nipple, I've got my tools all sitting on the table but I can't get the damn cap off the fluid reservoir. Obviously I've removed the screws. I will quietly admit that the fluid hasn't been touched since I bought the bike back in 2003. I've tried to gently pry the cap off and tried brute force with my fingers. Is there a secret?
Also am I safe to remove the tax disk holder on UK bikes? There's a huge bolt that holds it on but it doesn't seem to support anything else. Of course the bolt won't come out the hole either but hey ho.
Any advice welcome.
[EDIT] is it a vacuum thing? should there be an air vent?
