Could someone shed some light for me???

In days gone by I do the usual (old jam jar/bit of clear hose) and was always able to bleed system through without too much hassle, although I always think I could get them alot better!!
So I decided to buy the Motrax pneumatic pump which looks the business!! however I'm hitting a brick wall with it

There's instructions as to how to use, and one of the comments was look at Diagram 1 (no diagram anywhere?)

Anyway I plugged it on and released the bleed nipple, on squeezing the handle alot of air bubbles come through (great!!) but this goes on way too long and I've topped it up several times with air still coming through?? I believe that the air may be coming through the bleed nipples screw threads as it's alot stronger on pulling the fluid through. Do you reckon I need some grease around the threads to stop air coming through??

I thought this pump would aid me but im struggling at the moment
If anyone could point me in the right direction with this I'd be grateful.

cheers

Are you having a problem with bleeding the clutch line?
If so, I recommend a bleed banjo bolt (with a nipple) at the lever end. It made bleeding my clutch so much easier compared to before I fitted the bleed banjo.

Later 748/9** have a bleed nipple on the brake master cylinder too.

With these nipples it's no problem to use the jam jar and hose method!

I've had the same problem Steve and have gone back to the old method. Nothing better imo.

Ah sorry guys, but I'm bleeding the M900 Monster!! so no bleed attachment at that end.....Was hopeing for some info on using the motrax pump as it cost a few quid and would like to master it. Anyone used one before?

If its the same or similair to the Mityvac,yes,grease or ptfe tape on the bleed nipples for definite,as thats where the air is getting in.Also make sure your fluid level in the reservoir is kept topped up as you pump.I was creating too much of a vacuum the first time i used the Mityvac and the second i cracked the bleed nipple it was pulling the brake fluid from the resevoir fast as feck and i didnt keep it topped up.Still got the odd few bubbles coming through but just cable tie your brake lever back overnight and Roberts your mothers brother.
