It seems the Avid BB5 brake pads are too small and don't work well in the rain. Darn dangerous too as a review said. It is also reviewed that the BB5s needs constant adjustments, sometimes twice on one ride. Most of the reviewers who are also users of the BB5s recommended that it is safer to change to hydraulics but off course in the case of foldies, this is a bit hard. The next best thing is to change the calipers to BB7s which has bigger brake pads ( sadly more expensive too but you don't change pads often ) and also in addition the BB7s can adjust both pads distance. Avid BB7s are the best mechanical disc brakes in the market now and BB5s as reviewed, said the Avids V-brakes stops even better.
Look at the size difference

that is the concern but for foldie i think the BB5s is sufficient unless on MTBs then hydraulic comes in. Look at the size difference

i try the method as shown on the site below and it works good now so won't change anything on it as my budget is on building a flat bar bike using my old MTB frame
