Title: Braided Brake Lines - 2 instead of 3?
Post by: youngjohn on July 18, 2014, 07:19:43 PM

Has anyone swapped the one into two standard brake lines for two separate lines coming straight from the master cylinder to the individual callipers (on twin calliper bikes)?

If so, do you have a brand or part number?

Thanks.

Steve has done this and took some pics for me of his bike. http://www.bmwr65.org/cgi-bin/yabb2/YaBB.pl?num=1403614072

He said he got his from here: http://goodridge.brakes-hoses-fittings.co.uk.

I am going to do the same with my install as I build the bike back up.

Just curious, is there a functional reason for doing this or is it strictly aesthetics.

For me it is completely aesthetic as I want a clean front end.

Interesting - i guess that it balances the pistons on both sides?

Stock setup is balanced.  This setup would just be like moving the stock splitter all the way up to the master cylinder.

There is a lot of extra 'bracketry' and pipes on the original BMW setup, even more so with the R100.

It won't work any better, but it will remove any extraneous clutter.  BMW could always be relied upon to make a system more complicated than strictly necessary.

Cheers

OTOH When did you last hear of BMW brake lines chafing?

and, erm, splitters are found on every dual disc bike and multi-brake car I can think of.  Plus, if you're going to use a hydraulic brake light switch, as some of our bikes did, you need somewhere to put it.

The short steel lines down at the calipers are different than most motorcycles... but I guess there's some flawless engineering behind that... less stress at the crimped hose ends or something  ;)
