Third hand for setting up brakes

[robgul]

... and add to the 3rd hand tool* the "toe in" gadget that Tacx sells (clamps round the rim and lets you set the brake pads correctly) ... and of course a cable-puller is invaluable as another 3rd hand tool.

* the other thing I've used is a "g-cramp" ... the ones work like the guns you use for sealant tubes.

I adjust the cable tension screw right in, tighten the cable clamp until the cable is a slip fit ( not a p**s fit or a prick in a top hat ). I squeeze the calliper with one hand, pull the cable tight with the other and then let it go. Then tighten the cable clamp. When I release the calliper, the amount of cable slack residual from the process is enough to let the brake block retreat to an acceptable distance. If it retracts a bit further than I would like, I adjust the cable tension screw until the clearance is acceptable.

In other words, a third hand is not needed.

To get 'toe in' correct, cut a piece of card so it posesses a 2 deg taper ( 1 degree each side of a centre line ) and can fit between the brake blocks. Using a pair of soft jaw pliers, mechanically adjust ( bend ) the calliper arms until the card 'profile' gauge fits correct with the centre line parallel with the brake's mounting bolt.

Once you have the gauge, keep it.

Yep,you can buy a thirdhand tool but personally I've never found the need for one.
I use either an old toestrap or a spring clamp/G cramp/zip tie/molegrips/adjustable spanner/string or even a bit of black tape,etc .
I'd bet you could make a third hand tool from an old wire coat hanger if needs be,it really isn't rocket science.
