I agree you can use a cable for the other side in an emergency.  In order to get Eric going, does anyone know whether you can fit an AW11 cable to a SW20 in an emergency?

BTW, although there are different part numbers for rear cable kits for each side, and the guide brackets are different for the left and right, I believe the actual cables are the same.

probably... a brake place once did mine up with shackles and crimping and it worked a treat till the next time i snapped a cable.... i can't remember EXACTLY how they fitted it though i just distinctly remember seeing they'd just made something up....
 
if one sides working it sounds like something might be jammed as well cause the main cable pulls onto a balance bar which connects to the two rear cables... if ones broken the other sde SHOULDn't do jack...

Well, Doctor, we can always try. 

Did you want anything for the handbrake cable??

PM sent.

Okay the AW11 Cable seems to Fit, but that's all my mate told me.

If this works it might make everyone's life easier since the cables can be swapped between the two models

Thanks
