Any difference in size?

Think mine needs a rear cylinder as pedle isnt firm and sinks to the floor with car off or running.

got braded lines all round aswell, how much would braded lines be from the master cylinder-calipers/cylinders be?

Also, if I was to get rid of the rear load sensor valve, what woul di replace with apart from a bias valve, im sure the twins got inline valves or something?

Plan on upgrading to braded lines from Mk5 RS2000/130ps master cylinder, cossie discs and S2 calipers
