I was changing the tubes on a 1980 Raleigh 5 speed with side pull brakes. These are the original brakes. When I went to reinstall the wheels, I could not figure out how to release the brakes, so I let the air out of the tire so I could get it past the brake pads. There is a spring wire that runs from one side of the brake to the other, and I tired releasing that wire, but it didnít seem to do anything. Can anyone help me? I got the wheels on the bike, but Iíd like to know how it is supposed to be done. Thanks in advance!
