    Brake lines

    Upgrading the brakes on my '16 XR very soon (buying the parts ready) and it's time to try and get the lines sorted. Checking out ebay pics, it looks as if the O.E front line from Master Cylinder to ABS unit is braided-rubber-braided, can anyone confirm this or if it just looks that way but is actually braided all the way?

    Has anyone changed this line when putting on a Radial M/C for straight braided line and know the length / Banjo ends used?

    From ABS to Caliper I'm going from posts in the "Brake upgrade" thread which seems to be (from ABS end) 20degree banjo-1135mm line-T piece-(X2 90degree-450mm line-20degree banjo)
    The suppliers I'm looking at offer 1125 or 1150mm line so going with 1150 as figure slightly longer is better than tad too short.

    Can anyone who has upgraded the brakes already confirm if this all sounds right? Basically I'm trying to get lines sorted without stripping the bike to measure as it's a twat of a job getting all the bodywork off/on and I use the bike too regularly to have it stripped and lines off for 2-3 weeks while they're being made/delivered etc.

    the lines are braided and solid, the only rubber you see is covering. BMW has made some sections of their lines from metal pipe, bent to shape, but you can replace with standard braided lines the whole way.

    Thanks for that Simon, thought it looked like rubber in the middle section as a) pics were a bit crap and 2) different ads have it bent round differently so didn't look consistent as you would get with solid brake pipe , but that may be the breaker bending the pipe when removing.

    If you are going to a radial MC then HEL do a convertor so you can use the standard line from the MC to the ABS pump.

    As others have said the front lines are braided and then go into solid lines.

    I ordered line that were 1135mm from the splitter to the ABS block and the two caliper legs need to be 450mm, again ordered from Hel.

    This was for use with M50 calipers.

    Thanks,
    I have already ordered the Radial adapter but still waiting for it . . . . . . . . . . . .
    Those are the measurements I have but HEL want me to send in my lines so they can copy them, even when they have made some previously but say they didn't keep any records of what they made, inc the t-piece. I'll be honest and say I've not ben very impressed with them so far and am now looking at Venhill instead.
    M50 is what I am putting on too with MCS19-21 from a Truimph 1200rs

    That's the 17mm master cylinder isn't it? If so that's what I am running and it works really well.

    Bazzer, did you use the HEL adapter for the m/c? if so how did you get the length for the top line? Just eyeing it up, the std line looks too tight when bars are turned to the left

    I did use it and it is tight on the top of the triple clamp, but remember it all moves together at that point so you don't need any slack.

    I put some heatshrink around it as it was touching the edge of the top yoke to protect it thhough.

    Cheers for the reply, but already fitted, I ended up moving the M/C in a bit as the mirror mount is now separate from the M/C mount and that gave me just enough.

    Now thinking going to change the line anyway, as the adapter looks shite. Just need to know the length of line from ABS unit to Radial M/C (or even to Std M/C and I can add a couple inch) if anyone has already done this
