Problem changing brake fluid

[chris-foci]

I'm currently changing my brake fluid using a Sealey pressure bleeder.

I've pressurised the system to 15psi and I've cracked open the r/n/s nipple but there is barely any fluid coming out. Been here nearly an hour and only collected less than 100ml.

What's going on???

Blocked nipple?

Wind it all the way out and check.

Its possible I suppose.

I moved onto the front which worked a dream on the N/S but the nipple is rounded off on the O/S/F so I will have a think and finish the job another day.

Heat it with a blowtorch, then rapidly cool it with WD40 or plusgas, breaks the corrosion and draws the penetrating fluid into the thread.

I'll give that a go when I try and remove it. Cheers

Also, its a good idea to change the brake nipples to stainless versions if you have the mild steel versions.

Source: I snapped two nipples when trying to bleed them.

I have some stainless ones en route at the mo so will fit those once they arrive and give it another go. Im hoping its just the nipple thats blocked.
