Super cheap technique:Tube, empty bottle/jar/jug, spanner, a cable tie and some Dot4. Crack top off reservoir and remove rubber seal. Fill empty bottle with some Dot4 (new or waste), spanner on nipple, tube on nipple, other end of tube dunked in Dot4 in bottle. Then you get yourself in the rhythm: open nipple with spanner, squeeze brake lever, close nipple, release brake lever; open, squeeze, close, release; repeat until you see no more bubbles going into bottle. Then repeat for t'other caliper.Throughout, watch your reservoir, never let fluid empty completely from it, keep topping it up. Secondly, ensure the tube end is always submerged below some fluid to prevent air flowing backwards into caliper. Then just persist, last time I did this, I ran through about half litre of Dot4 until I got no more bubbles from either caliper. Finally, once both calipers are done and cleaned up, stick the cable tie on brake lever pulling it in. Leave it on overnight, can sometimes help the last stubborn tiny bubbles to slowly rise up to reservoir.
Cheers Arfa, I reckon the nipple diameter's about 6mm, I'll measure it it daylight with a micrometer before I buy the wrong size of clear vinyl tubing!
Piece of clear tube, 8mm spanner, & an old coffee jar... does the job every time

The best home made bleed kit I have seen is a bottle to catch the excess fluid and a clear rubber pipe with a bolt screwed into the end and a small slit cut in the side to act as a non-return valve.Drop the end with the bolt into the bottle, put the other end on the bleed nipple, open the nipple and pump away on the lever till you get clean fluid coming down the pipe. Tighten up the nipple and confirm you have pressure at the lever. job done
