My 2000TW front drum brake works fine, stops the bike real well, no screeching or funny noises, but it sticks after you squeeze the brake, won't release, gets hot after you ride a few min and makes it real difficult to roll the bike. You can release it by knocking down the lever on the left side of the wheel, but when you apply the brake again, it won't fully release, still binds the wheel. We have a tremendous amount of humidity down here (live right on the water), and it could be due to rust or corrosion either inside the brake cable or inside the brake in the wheel.
I would like to try and inspect and lubricate the cable first but can't figure out how to get it off the brake lever or the lower end, and it doesn't help that everything is lightly coated with a fine layer of rust on all the nuts and bolts. I have soaked everything with PB Blaster and can turn the adjusting nut at the lever end, and the nut on the bottom at the lower end fixed to the wheel, but that's all I can do. Is the upper cable end screwed into the lever mount, or how do I get the cable off? I really don't want to take the wheel off but if the cable is free, I may have to do that to look inside the brake drum and see what's stuck in there.
Thanks.

You need to back the adjusters way off. You want lots of slack. then line up the slots in the lever, adjuster, and lock nut. I'd inspect the cable. If it is sticking you can try to lube it. But I'd err on the side of caution and replace it. I'd also pull the front wheel and inspect the brakes and hardware. Lube the pivot points and mating surfaces where the pivots touch the frame of the shoes and where the frame of the shoes contact the backing plate. Very light on the grease and do not get it on the linings or the drum.

GOF - I'm aware of everything you wrote and I can easily loosen the large diameter adjuster that's against the lever mount (holder), but I can't move or turn the cable end. Is that screwed into, or just slides into, the mount that the lever attaches to? I need to be able to get the cable off the lever and the mount. I may have to pull the lever's pivot bolt out and then get the cable end knob off the lever, but how do I get the cable off the mount?
The two nuts at the bottom end attached to the fork don't seem to adjust anything, it seems to just hold the cable to the fork on its' way to the brake lever on the wheel.

Can someone tell me how to remove the cable from the brake lever and holder (mount) at the handlebar? I can't lube or replace it unless I can get it off.
Why would worn pads bind up the brake? And my bike only has ~5000 miles on it if that makes any difference.

because if theyre worn beyond a certain point the cam that actuates them rotates to a point it cant easily return from. had this happen to me on another bike

I guess I'll just have to soak the crap out of it with PB Blaster.
The upper end just slides into the holder, it's not screwed in?

I finally got both ends of the cable off. PB Blaster is your friend.
Altho both ends of the exposed cable are shiny and nice and clean looking, I have to pull it really hard with a pair of pliers to get it to slide through its' sheath. The brake lever at the wheel moves freely and instantly springs back to its' resting position, so obviously the problem lies within the cable itself.
I sprayed a fair amount of PB Blaster and Corrosion X into the upper end of the cable and tried to work it back and forth but so far it hasn't done a thing and has not dripped out of the bottom end yet so I will just order another one online and then sit and wait for it to arrive.
I'll let you know what happens after the new cable arrives.
Thanks.

P.S.
My throttle cable runs free really easily (see another post on here about it) and my clutch cable seems fine, but I may lube that while waiting for the brake cable, just for the helluvit.

I would go ahead and lube all the cables. An ounce of prevention and all that. I would also pull the front wheel and inspect the bearings, shoes, hardware and lube what needs it and replace anything that falls short of optimal. Easy to do and could prevent problems down the road.

The new cable is supposed to arrive today - real quick shipping and delivery. I'll lube it up before installing it and let you know how it works.
Then, the clutch cable, even though it's working fine. Already did the throttle cables.

I'm sure I'll find something. This is, after all, a 19 year old bike but it still runs fantastic.
And I have to find some reason to talk to you guys, right? Isn't that why we're all here?:eek:ccasion14:
