ok so i got a haro f3 from a friend. It was in horrible condition, i am no expert but i was able to remove rust, change worn tyres to new ones and dissemble the brakes. well the problem is that i dissembled the rear brake (sort of) and put it back together and now the pads are really close to the rim. any now how to dissemble then reassemble u-brakes. thanks in adance
These are set the way Retro Grouch described except it takes a 13mm open end wrench. You have to play around with both sides to get the right amount of tension and to get them equalized. These brakes are very old school. Newer brakes may have an adjusting screw at the base of the arm.
