Loosen nipple , put length of clear pipe on it attached to a syringe body, fill syringe body with some brake fluid, fill reservoir and SLOWLY pump peddal watching for bubbles in pipe on nipple , keep topping and pumping , this allows air bubbles out without drawing air back in when you release brake after pump motion , you can also use the piston pots on the caliper to push any air caught in the caliper body out by levering them back in off the shoes , this is what i do when air is a bastard to clear , the smallest bubble can fk it all up , good luck

Release some pressure on the brake cylinder ie back off the threaded adjuster on the foot peddle...this may need adjustment through the process.
Ensure resevoir is full then undo the banjo bolt [slightly] at the top of brake cylinder proceed to pump foot peddle you should see the air being pushed out?
After tightening that banjo if your happy - undo the rear banjo to rear brake cylinder at the end of the brake pipe  Rolling Eyes  proceed to pump foot peddle and release any air and tighten banjo the remaining air can then can be removed through the bleed nipple an easy bleeder is very handy for this placed in a clear container with a bit of brake fluid in it...

At all times check fluid reservoir is full or there abouts your simply working fluid in stages through the system...!!

If the brakes still give problems you may have to change the rubbers inside the brake cylinder [kit about £20] its good to know how to bleed your brakes as may be needed on the trail!

If unsure then have a mate to show you must get it right or take it to a mc repair establishment... Very Happy

Because of my amazingly busy lifestyle it has taken me 2 years to get back round to working on this bike lol.
Anyway, used a syringe, it popped the tube off and covered my in fluid, bought a vacuum kit and still no joy. After much hair pulling I discovered the bleed nipple was actually blocked.

This bike isn't in use or anything, it's a long term project that is just sitting in my garage. Might be finished in 20 years at this rate :p.

I tried that, it just shot the tube off and covered me in brake fluid.

Open the nipple further or work the pedal a bit whilst squeezing the syringe
