73anth Posted April 3, 2007 Report Share Posted April 3, 2007 gonna try to bleed the rear brake, where is the resovoir, what part needs to come off? if anyone has a picture, that would help. Quote Link to comment Share on other sites More sharing options...
73anth Posted April 3, 2007 Author Report Share Posted April 3, 2007 found the resovoir, opened the bleed nipple and pumped the brake. a bit of black fluid came out, then it stopped, i had filled the resovoir, and the level never went down. when people say"bleed it from the caliper end with a syringe" do i have to open anything at the other end to let the fluid flow?

coxy Posted April 3, 2007 Report Share Posted April 3, 2007 obviuosly the bleed nipple will have to be open and also open the reservoir top because your pushing fluid back through the system into the reservoir so it will overflow out of it so put the reservoir in something that it can overflow into and keep syringing the fluid through Quote Link to comment Share on other sites More sharing options...

windlestone Posted April 3, 2007 Report Share Posted April 3, 2007 be careful back bleeding the gas gas you can turn the seals inside out in the master cyl. The problem is air gets trapped in the hose inside the swing arm, gently tap hose with a spanner to loosen trapped air Quote Link to comment Share on other sites More sharing options...

tomskiy Posted April 4, 2007 Report Share Posted April 4, 2007 Hi Anth, I've just sucessfully bled the rear brake on my 2003 280 Pro. The technique I used is a little unusual, but it helps to get any air bubbles heading in the right direction, out of the system! I ran the bike up the garage wall, literally, engine running, obviously, then roped the front wheel to a bracket I have on the wall. It will probably be easier to enrol an assistant to help with this manouever! I find having the bike at an angle of 45 Quote Link to comment Share on other sites More sharing options...
73anth Posted April 4, 2007 Author Report Share Posted April 4, 2007 cheers tomskiY, we tried all ways today!!! even the bike up the wall like you said, but trying to work the fluid from the resovoir to the caliper, hoping gravity would help us! the best we got was a slight grip of the disc from the pads. a mate is going to have a try tonight (good road bike mechanic). if he fails, i will give your method a go.

tomskiy Posted April 7, 2007 Report Share Posted April 7, 2007 Hi Anth, the rear brake bleeding method I use will only work if you bleed the system from the "caliper" towards the "reservoir" as the fluid will be travelling upwards, the way that the bubbles will naturally want to travel. If you tried to bleed the rear brake from the reservoir towards the caliper with the bike's front raised, this will make it more difficult to expell the bubbles than if the bike was sitting on the ground.
