cross brake?

The ABS is four channel.

Meaning from the ABS module there is a separate line for each caliper/wheel.

You might want to get some coated line. Its about the same price as the regular stuff anyways.

Make sure you have a good flare tool. Metric bubble flare.

Fittings at brake hose are M10x1.5 or M10x1.0 Can't remember.
