    Is there some magical way to do this or have I got a f*cked up master
    cylinder? Basically I stripped the rear caliper down as it had been
    sticking on. Coming to bleed it no matter how much I pumped the pedal no
    juice was forthcoming. I could hear air suck/blowing as the pedal was
    pressed though. So, tracing back to the splitter/switch I noticed another
    bleed nipple on it so I thought I'd try and bleed it from the master cyl
    to there. Opening the valve and pumping saw a small amount of very dirty
    fluid come out but once that was out that was it, the reservoir was full
    of nice clean fresh fluid btw. What had been in there was very dirty.

    Before I started the linked system worked fine so I'm surprised if the
    master cyl is indeed knackered.

    The order in which to bleed the linked system is:
    1. flow control valve (do be careful with the nipple on this one. They are
    very fragile)
    2. rear caliper
    3. l/h front caliper

    Cheers, I'll have another play tonight, it is a tiny nipple on the flow
    control valve isn't it!

    Yep. As they don't get bled that often (like when you're doing a fluid
    change), they corrode easily and snap off in an instant. Fucking, *fucking*
    things. As you might have guessed, I've done a couple this way on my
    SOGuzzis. The olnly solution then is to unbolt the valve and hold it lower
    than the rear caliper when bleeding.
    Cheers,

    My T3 doesn't have a bleed nipple on the flow/reducing valve. Can't say
    I've had any particular problems bleeding the brakes.

    I do the rear first then the front.

    Depends what it's in, dunnit. Doesn't rise very far in a bucket of
    helium.
