I can understand if you all think I am being very blond with this, but is there a trick to setting these blooming things up without having about 4 hands!?! The brakes are basically these (minus the rust!) -
The only way I can get them to work effectively is to either clamp the blocks to the rim tight, then undo the cable bolt, pull the cable tight and push up the 'bridge' thing and tighten the bolt, but this rarely means the brakes actually work without tightening the adjustor (bit pointless if you want some adjustment!)
or
Take the wheel out, squeeze the blocks together, undo cable bolt, move the 'bridge' and tighten up the bolt, put the wheel back in and hope it ain't too tight (more hit and miss, but gets more effective brakes in the end!)
Sorry if I'm being stupid!
