either everyone is really weak or just dont know how to apply brakes - I can easily lock up wheels in a mehran by mashing its pedal. As I said the brakes need to be correctly set and serviced.
old cars like the mazda 1500 had no brake booster - it stopped pretty ok - its pedal was designed to provide good leverage to the master cylinder, corona rt40 also was like that, All VW beetles were like that - and they stopped pretty good when the brakes were setup and serviced correctly.
rusted, siezed, galled out brake parts will not even stop if you gave it a booster, rishwat and candy at the same time.
