Hi and welcome to my listing for a a brand new brake cable clamp suitable for the rear brake arm of the Sinclair C5. Show as part "A" in the diagram in the images. 

Rear Brake Setup Instructions

1) Fit the wheel if you have removed it.
2) Ensure the rear brake lever (left) is in the relaxed position and the handbrake is not on.
3) Fit the clamp nut and bolt
4) Put the brake cable through the wire
5) Push the brake lever forwards whilst rotating the wheel. When the brake starts to engage tighten the nut to clamp the wire in place.
6) Ensure the nut is tight and the cable cannot slip.
7) Test in a safe environment.
8) Use the brake cable adjuster to make adjustments as the rear drum break wears down. (B & C in diagram)
