Hi,
knows anyone the exact lenghts of the brake hard lines for
any positions?

I have a set of replacement lines but doesn't know where which
lenght is placed

Thanks

I've only had to replace the right rear (so far).

Judging from where the MC and compensation valve are located (closer to the driver's side from center), the longer lines typically go on the passenger side (both f & r) ...

Eric's website has a diagram under this link that shows which goes where.

the page also describes by number where it goes from this diagram

Here's actual pictures of each line.
