Evening all.
I'm trying to pressure bleed an Up! and having issues with the flow rate of the fluid out the bleed valves.
The official manual says 29psi, so that's what I've pumped the system to. Once pressurised, upon opening the bleeds (all the same) the fluid very slowly fills the drain tube and forces the air in the tube up to the highest point. There then remains an air bubble at the highest point (and at various other points through the tube) and very very little flow of brake fluid! After 5 mins there is almost no appreciable change in the fluid level in a 2litre drinks bottle. I would expect at 29psi there would be a noticeable flow.
It does seem to flow out to start with and then almost stop!
Any thoughts, ideas or experience?
