This brings up an interesting question from me. I have a pre-facelift k11 autotest car I bought from a club member. Although he ran it on the road only to and from events 1/2 mile each way), he only ran front brakes with rear from a hydraulic handbrake with remote reservoir (and very dodgy rear brake lines loose from either side of seat area to drums, no flexi ). I'm restoring rear pedal braking through the hydraulic handbrake, single line. Both rears are blocked off, so can I get away with just using 1 port, or, like Sherman, combine both ports with a T. Also, if I only use one port, is there a preference?
