Gonna get this GSL rear end swap done if it kills me!

Emergency brake questions. FB drum brake rear, upgrading to a GSL disc rear.

- How do I tell which disc brake cable is left and which right. They are different lengths, and I matched the longer side to the same side as the longer drum brake cable I removed. Left has a white stripe around its housing if that’s a clue?

- Can I adjust cable tension at the caliper? Left side seems too tight. Looks like I can adjust using the nuts on the threaded barrel in the picture below. However the nut circled red will not move. Seems it should as has a lock washer. Do I grab the nut circled green with a wrench then break the red circled not loose. (With cable removed from its caliper bracket, and the nut soaked with Blaster). Don’t want to force the wrong thing and break something.

Nothing I can find in any manual I have, or on Foxed.

Thanks!

 

Yep, one side is longer. It'll be obvious if the cables weren't installed correctly.

I think putting a wrench on the hex in green may make it spin on the cable cover.
The red circled nut is all the way back so the cable should be at its loosest setting. Did you loosen the cable tension at the handbrake?

 

Got it!

Applied some common sense and a tape measure and worked out that the threaded barrel, nut and saddle were the same length in both sides, so only difference is the length of the cable from caliper bracket to cotter pin… which does not effect adjustment at the caliper.

Sooo…. Fiddled some more with the red circled nut and bing! It does move and cured the problem.

Now I know the nut moves it’s dead simple. I was a mountain bike mechanic for many years and bike systems are the same principle.
