i have an eesibleed kit if you want me to come try see if it helps ?
i struggled for weeks trying to get a decent pedal on the shogun ,, the eesibleed makes it easy tbh
eventually i found rear inner pads were badly worn down ,, onnce i replaced them the pedal became perfect so most likely i was chasing air that was never there
also i doubt they have a bias valve on a scoob as theyre usually on vans and 4x4 etc but if there is one it usually also has a bleed nippple
