>>1709603just a drip or two and a little bit of cable movement
important to oil where ever a cable leaves its cable housing / bowden
the rear brake housing looks about the right length
what tends to happen is the brake cable will try and straiten what ever curve is in its rout, so it good to have long smooth bends
with this particular routing the rear cable housing can shimmy its way up towards the brake lever over time
carefully pull some of the cable housing towards the brake calliper
apply the brakes a few times to see how it settles, then use some electrical tape to hold the housing in place
the stem shifters can be mounted at a slightly higher hight to adjust the curve of the cable housing below it
there is a band on cable stop affixed to the down tube, it looks rusted in place, this part is what holds the cables in tension
it will loosen the shift cables if moved further down the down tube, dont mess with it unless you are ready to re adjust the derailleur
final notes
the brake extension levers are particular to each size and shape of handle bar
most are affixed with a large screw, this can be tightened with a flat blade cabinet screw driver (8x1mm - 5/16) or Philips T2/2-R2
if the washers on the extension lever are worn out further tightening the bolt does not help to stop the extensions from wobbling about
if the free-wheel is a suntour you have to be very gentle when removing it
sun tour free-wheel removal tools are farely weak
dont be in much of a hurry to mess with anything, take time to observe what is causing a condition, old bikes are tricky like this
