I prefer Gunson's Eezi-Bleed. I purchased it from Victoria British quite a few years ago and it works off of 9lbs pressure on your spare tire, flushing out the old fluid and sucking in new. It's like a pressurized faucet. Just fit an air tube to your master cylinder cap, attach the air tube to your spare tire, open the bleed valve, and it flushes out the old dirty fluid and sucks in the new clean fluid. It's the easiest, best system I've ever used, and it also works for the clutch master cylinder. I believe it's manufactured in Sweden. Make sure you follow the correct sequential procedure for which line to bleed first. Cost for the Eezi-Bleed System was around $30. IT DOES MAKE A DIFFERENCE. Also, if you use regular hydraulic fluid, make sure to use ONLY Castrol-Girling. Anything else deteriorates rubber components in the master cylinder.
