Brake problem

I am having a problem with Dia-compe sidepull brakes.
When I pull the front brake lever the lever is mushy and loose, and the brake pads close but stay against the rim, and have to be opened by hand.

Anyone know how I can fix that?
I'd rather not replace the brakes if I can help it. Thanks.

Is the spring or something else obviously broken?

If not, I have a pair of Dia-compes that I took apart cleaned, lubed and reassembled that helped a lot. If after this it feels better, but still doesn't stop well, I would change the pads.

It could also be the cable hanging up somewhere...

Remove the cable and see if it's the cable or the caliper that's not moving freely. Clean everything, squirt some oil the cable housing. Changing the housing and cable without any fuss can't hurt, either.

It's prolly a combination of old, weak springs, messy, unlubed pivot point on the caliper and subpar cabling, including dirty, cheap, old cable and housing, housing left too long and/or with sharp turns.

Maybe I'll just use the rear brake to stop with. I wasn't counting on taking everything apart. Thanks guys.

No offence, but, were you expecting us to give you a spell or something?
You may just need to put more tension on the spring. It's basically just a bar that rests on a pin on each arm to bring the pads back out. YOu may jsut have to pull it out from behind the pin and bend it out to add more tension. There is also a screw to do this but doesn't do much, it's more for fine tuning.

Just like a motorcycle, the front brake does most of your stopping. Using the rear only may put you on your ear.
I just had one of the guy's bikes doing much the same thing; the cable was kinked at the frame guide.

+1 If it helps, I just mumbled some hocus pocus sounding words and waved my arms around a bit. My coworkers think I am nuts. Go check your brakes and see if they work better now. If they do, please do not have me burned on a stake.

No offense? Man I asked for some advice because I don't know anything about bike parts or how to fix them.
I was looking for some constructive advice , the sarcasm helps me how?
Why bother responding at all if you're just gonna be an ass?

You post on a forum seeking advice. When the proper constructive advice is given,you pass it off and make a remark about using just the rear brake. If you never had any intention of repairing the problem, as your reply makes it appear, then you expect to receive some sarcastic, joking replies for wasting our collective time. Maybe a better thing for you to do is accept the advice with a simple thank you and not a silly remark. I bother to reply in the hope that the sarcasm helps you learn to graciously receive help/advice and not waste others time.
