Evening all, I'm planning on changing the brake fluid out of the front brake tomorrow and whilst I've done it before I seem to remember there's a sequence you need to follow for the ABS. Something about cycling the ABS or something. Sooo could someone either describe it to me or share the manual so I can do it proper. Ta
Straight forward but .... it pays to be able to pump the m/c lever without stopping so would help if you have someone who can continually top up the fluid reservoir. If in the unlikely event you have air between the master cylinder and the abs pump, this should push it through. Air between the abs pump and caliper is not an issue. Bleed the m/c nipple first, then the nipple furthest away from the m/c, so left hand caliper. Bleed until you see the new, clean fluid coming through. Then go to the right hand caliper and repeat. 99 times out of a hundred, job jobbed. If you are confident and you have a dead straight bit of smooth tarmac that you can brake from 30mph to operate the abs, please feel free to do so. I, however, have never been brave enough nor did I feel it was necessary. Andy
Should be fine just bleeding it regularly, only becomes an issue if the lines are dry or there’s air in the system
Cheers. I'll be using a vacuum pump to make it a whole lot easier. I used this last time but sucked it through a bit swift so think I got some air in as it feels soft until I've pumped the lever a couple of times. Problem was the reservoir not sitting level so when I was looking up to it it looked like it was half full......lesson learnt.
Might go wild and try both methods.....must admit I've bled more without the vacuum bleeder. Had a cb500 which I was bleeding every couple of weeks due to a knackered caliper. Got the vacuum bleeder when I had a TLS as a recommendation from a friend. I'll give the m/c a go manually and see how I get on. Cheers all. Looking forward to getting out and about once we're allowed out to play.
If you do not allow the master cylinder to run dry, you can suck it through from the nipple at the calliper using any method you like (I use a large syringe). Its obvious when the clean stuff comes through. I did mine a short time ago - it took about ten minutes to sort However if you allow the cylinder to empty - you will have problems with air.
