How to loosen stiff kids brakes My eldest son has a Hoy Bonaly 16" but we've always suffered with very stiff brakes. (< ![enter image description here]( It has Tektro RX1 levers I've tried loosening the spring tension in the calliper which made only minor difference. I suspect my next step would be to lube the cables and see if that helps. There are no kinks or tight bends in the cable run so is there anything else I can do to ease these off?

It looks like the issue for one brake stemmed from a ferrule on a cable outer pinching too much. And the other brake seems a little better after checking/straightening the routing and lubing.

All inners and outers look to be in perfect condition which is why I hadn't stripped them down up to now.

Thanks for the pointers chaps.
