Hi All,
You can try turning the brake cam 180 degrees,
or the shoes can be packed by making steel "shoes" folded around the flat ends
Its equally important to get the lever on the crossover shaft working at 90 degrees to the cable as well
I have found that the brake cables being sold are too long resulting in a loop hanging down
On my SR I had to pack out the relined brake shoes(NOS linings) to get the arm at the correct angle
I shortened the cable outer to get it to run as straight as possible, and re soldered the ball end back on the shortened to suit inner
I can now lock the back wheel if required
*warn*Being competent and confident at soldering is a requirement for modifying brake cables
*warn*The consequences of failure can be fatal
Silver soldering or brazing overheats the steel wire and wrecks its temper
