Lengths are derived from that of NAMI Logan 4-Piston (Burn-e) which is the most generous of all common 11" wheel scooters.
Hose terminates on the outside of calliper rather the inside adopted on HB427-4M and Logan 4-piston to help clear tyre sidewall. The non-banjo design reduces points-of-failure and exposure of hose to damage where it terminates with the lever.
