I know this has been probably been done to death on the 'old' forum, but I'm struggling to sort out a spongey as anything rear brake.
I had a GP200 engine fitted into my S3 Li125, everything running fine except the back brake.
I've tried the usual 'fixes'
- Made sure the cable is tight to the footbrake
-replaced the inner/outer cable to correct length as detailed in Spanners
-replaced the inner cable with a quick adjust threaded cable
-tried different brake shoes (li/gp)
-lightly sanded the hub
I noticed that both drum brakes are making contact with the hub, with no obvious 'clean' patches.
If I adjust too much, the wheels lock on, If I back off the adjustment a turn or two , the brake is spongey as anything?
Any pointers to where I should look next?
Thanks
