The FA50 brakes are great !!
The previous owner had moved the front brake arm one spline to the wrong side ... leaving less movement till the arm hit a small boss on the brake hub... stopping the arm before the brake shoes had a chance to apply much pressure to the drum .. so they only got a little brake force.
I found that .. and moved the arm over (to the line Suzuki provided) .. and the brakes are great... better than a Tomos .. even better than my PA.
I can understand why the owner did that .. Suzuki made it so that you have to partly assemble the arm... then twist the arm some.. then finish assembling it .. kind of like a jigsaw puzzle.
.. he took what looked like the easier way out.
... great ... I don't have to buy anything or adapt anything.
