Nope. The cap has a breather hole in it anyway to allow air in.  :y

Air will only get in if the level is allowed to get very low, or part of the system downstream of the reservoir is disconnected. Air results in a spongy pedal at all times so the fact that you have a hard pedal (albeit creeping a bit) rules out air in the system.

I would try Mark's master cylinder seal trick. :y Assuming there are no obvious fluid leaks.

Bleed the brakes first matey....
Is the fluid clean or slightly black??

This can happen to the pedal sometimes on a pad change, it happened on mine, i changed the fluid and bled the system, then all was well again.

'O' ring????? Never played with the Omega brakes but I'd change complete master cylinder. I have even read in the past, that it's best to change master cylinders complete with the servo, that way you're distubing as little as of the hydraulics as possible.  :-/  :y

Did Mark's master cylinder seal trick and it made the brake alot better but still not 100 per cent.Iv checked the brake hoses and there fine too so i think i might be looking at a new master cylinder or do you think i should still try bleeding them

when you say alot better do you mean it still goes to the bottom but slower or does it just feel spongy now?

Ok, then before you go off buying new parts I'd drive it (carefully) for a couple days. Chances are the pads just need bedding in and the pedal will probably return to normal after a few days

Fingers crossed  :y

I've had a similar problem in the past and it took about 60 - 70 miles before they returned back to normal.
