I have a men's bike that says Venture on it. I think it is made by Raleigh and I am having trouble adjusting the front brakes. They say Lee Chi on them ( side pull ). At first they wouldn't budge so I took them off and cleaned them all up and oiled them where oil was needed, then made sure they were put back on the bike the EXACT way they came off but when I apply the brake only one side pulls in. Yet I have checked that they are centered and there is no play in them and when I squeeze them by hand they both go in and out smoothly. I must have missed something but not sure what. Can anyone give me some advise on how to fix this problem. I have even tried to center them with an offset wrench and a wrench on the back nut. This brake assembly has two nuts at the front of the brake and the slot for an offset wrench.

Thanks... Greg
