General Bicycle question. I bought a used Japanese "MTB" the other night because it met a lot of the requirements for a GEBE or even Happy time. Had slick tires on it. High handle bars. Simple, tight. Good Candidate. EXCEPT. The brakes sucked.. Hard as I tried, I could not skid the back wheel. Even pulling the front brakes in you could not get a high rate deceleration. Compared to my ebike even which has 50 extra pound of battery and motor hanging in it, the light MTB was worse at stopping. I figured I could fix them so I bought the bike. The pads were REAL small so I changed the pads to bigger but not as big as my other bikes and still no joy, still poor braking. It's like the leverage is not right and I can't get enough PSI on the pads. I may try a set of bigger pads(if they fit) but thought I would run this one by the group. In order to get my kit under way I bought yet ANOTHER MTB off of Craigs list and my wife cannot believe what she is seeing in the Garage. I just told her... "Don't ask"
