As header. 1400 failed it's MoT today as both sets of brakes were very\nspongy, with too much travel. Pads are fine so almost certainly air in\nthe system, I are told. ( He was fine with the exhausts,which was a\nresult ) .\n\nSo, I did a quick google to see what UKRM had previously said on this,\nand got this from TOG in Feb 03:\n\n++++++++++++++++++++++++++++++++++++++++++\nTo bleed the brakes: attach piece of bleed pipe to bleed nipple. Put\nother end of pipe in glass jar.\n\nPump lever half a dozen times, and then pull in. Without releasing\nlever, open bleed nipple.\n\nClose nipple. Release lever. Pull in lever. Open bleed nipple. Close\nnipple. Release lever. Pull in lever.\n\nAnd so on and so on, remembering to top of the fluid reservois as you\ngo. When no bubbles come out of the pipe and the lever feels firm, it's\ndone.\n+++++++++++++++++++++++++++++++++++++++++++\n\nNow, that seems easy enough. Just a quick question - before I do this,\ndo I remove the appropriate cylinder cover for the brake I'm working on?\n\nAlso, is the pipe/jar interface just to stop brake fluid hitting the\npaintwork?\n\nFinally, is this the 15 minute job it suggests or could I be there for\nhours deopending on amount of air in system?\n\nIf it helps, when I press the rear pedal as is I hear a slight knocking\nsound - would that be the pistons trying to move out?\n\nTa in advance, as always.
