so would care to explain the proper way then?
Same as D, but with a little more detail, just posted this in another thread as well :)
To properly bleed your brakes:
***NEVER do both front and rear at the same time! Do the front, ensure correct operation then do the rear!***
Do nipples in this order: MC, Right Side, Left Side, Right Side, Left Side.
1. Wipe down all surfaces around the brake components, and anything above them to prevent any contamination of the system
2. Put a piece of tube over the nipple, run it to a container
3. Get your resivoir level
4. Remove the cap from the resivoir then place back on top, again to prevent crap getting in (don't do it up)
5. Squeeze the brake lever and hold in (use a cable tie to hold it if you like)
6. Undo the nipple slowly so that the fluid runs out (the lever will go in further at this point)
7. Do the nipple back up
8. Let go of the lever and squeeze again
9. Repeat cycle until fluid runs clear and there are no air bubbles, then move on to the next point.
Once you are done make sure that the nipples are all done up correctly and that you have good a good lever (you can feel the pressure in the system)
Take the bike for a ride at LOW speed and test the brakes, this is why you don't screw with both at the same time cause you don't want to go for your test ride and find you have no brakes at all.
Once you have completed your test ride inspect the brake nipples for any fluid seepage and rectify as necessary.
Now do the rear...
After a week or so has passed, reinspect the bleeder nipples for seepage.
Let the master cylinder run out of fluid, keep it above 1/4 cause you will have to start again if you let any air in
Allow brake fluid to get onto paintwork or tyres
NEVER reuse fluid
Leave either the master cylinder or bottle of fluid uncovered
Use a different fluid (it's also best to use the same brand, if your unsure and just topping it up - do a full flush)
Clean anything besides the piston seal grove with brake fluid
Allow the piston to extend to far as its a bitch to get back in
Allow water within a 3 mile radius of the brake fluid, its hygroscopic meaning it will absorb water, leading to corrosion inside the brake system and catastrophic failure may result (that's a bad thing)
