Sorry, might be a bit late now...

I had the same problem on my van, NSR no fluid out of nipple.

I just systematically checked every joint in the pipes to see if there was fluid seeping out until I traced the problem to a totally blocked flexible hose at the radius arm. I took it off, pushed an old choke cable through the pipe to clear the black solids out of it, filled it with WD40 then attached a bicycle track pump to one end and pumped until there was little resistance (it took 150psi to shift the crud in there). Re-assembled and bled the system, has worked fine ever since (just passed MOT too).

For future reference... do NOT do that.

The standard rubber in brake components is EPDM. EPDM is perfectly compatible with brake fluid but 100% incompatible with oil and grease. When you read any service manual it dances around this by telling you to only lubricate brake parts with either special brake grease or clean brake fluid.

Also for future reference, it's not at all uncommon for old brake hoses to collapse on the inside as you have experienced. The repair is by replacement. You have just passed MOT so I doubt you'll look at this any time soon. However, for safety... please replace the hose that your reamed out and please don't wait for a brake failure.

I second that very very dangerous, for the price of a new hose it could be your or someone elses life at risk

Haynes is as helpful as usual just saying remove it like i never though of doing that to remove things.

It should just slide out - but i have no idea where you will get a seal kit for it!
