As already said bleed the brakes but if you don't know how old the brake fluid is change it all & re-bleed, when the old fluid needs changing you may get brake fade & the pedal travel increases, I have had this happen in a emergency stop situation best to get it sorted asap.

It is 18 years old and I have no records to speak of re servicing so a rear bleed and fluid replacement it is I think.cheers

I have done it before but the clamp on the rear foot pedal to create a lever, ever seen that and will use it in the future!
I have to comment that I think adding new fluid into the existing fluid in the reservoir is not best practice.You are effectively contaminating the new stuff with the old stuff that is still in there.I always syphon out as much of the old fluid from the reservoir as I can, before topping up with new fluid for the first time, to avoid contaminating it as much as possible.
Didn't see him emptying the reservoir so fair comment on that Bandit.Didn't make myself very clear looking at the rest of your comment though as, after the first top up of the reservoir, I then bleed the system exactly the same way that he does.I don't just top up the reservoir and then do nothing else.That's not bleeding the brakes
