Ok so My CSP Silvia has the same sumitomo braks as some roaders . Twin single calipers each side.

According to what I have read they are supposed to be "handed" inside and out .I cant see any physical differences on mine apart from the obvious- only one each side has a bleed nipple.
Can anyone point out something I am missing because to me if you forget what pipe goes where all four appear to be the same.

Also I have to change all the system including the hoses ,pipes ,calipers and brass joining blocks . Is there any technical reason why I cant put the calipers in parrallel rather than in series as that seems to me to be a better set up in principle. Happy to be put right though.
Obviously if I do the calipers in parrellel the first question answres itself

The Nipples for the hard lines are of two different type, some bobble and some double flare. Running them Parallel would be a nightmare of lines and junctions plus each piston would need a bleed screw. No advantage to Parallel, but doable.

Im in the Uk so have to make pipes up or its at least a three week wait from the US plus with duty and carriage they end up anyway so expensive - at least x 5 . So which nipple is hardly a problem its just a different end tool i just copy the old pipes.
Re no advantage . I have to also buy new brass junctions that are boltedto the hub and two outlet UNF blocks are like hens teeth in the Uk and I have three way with the correct fixing hole already so for me parrellel will work better but thanks for the imput.

Since you will need to add a second bleed screw to the top of the outside cylinder, be sure that you have clearance to the wheel for them.

Also, when you bleed the the brakes you will have to remove the wheels to get to the outside bleeders.

Peace,
