Evening all, quick bit of advice needed as i'm away from home at the moment so can't measure them to order them. I need to replace the brake lines on my 2000 X100 XKR. The rears were picked up for corrosion on the last MOT however on stripping them out the fronts are far worse behind the front arch liners. They look to be the OE pipes from the factory. I'll bite the bullet and change everything out back to the ABS distribution block. From memory, the 4 lines exit the distribution block in a single row of 4 lines on the outer side however i seem to recall there being two size fittings there, two large and 2 small. Can somebody confirm the two size fittings used on the outlets to the ABS distribution block please and if the bottom of them is convex/concave etc.

Regards, Pete
