rear break lever sticking....?  By  brandon667 (Read 699 times)

your brakw shoes are probably worn out, hence the squeaking, or the spring is broken back there. Worn out shoes will stick.

The cable operated rear brake requires lubrication at a number of points and you really need to remove the muffler and rear tire in order to do it correctly. I requires a dot of silicone brake grease to be applied to the brake shaft where it goes through the backing plate, on the cams that engage the shoes and the pivot pin between the brake shoes. The brake cable also needs to be lubed with cable lube to keep it free and to prevent water from getting into it. If its the cable or brake lever on the left handlebar that is sticking then lube away with no worries. The shaft going through the backing plate on the rear hub may if stuck may free up with a one or two drops and no more of penetrating oil (WD 40 is more of a water displacer and cleaner) or better yet one of the newer High Detergent ATF fluids from one of the cars in your household. You only need a drop or two so even whats on the end of the dipstick on a cars transmission will be way more then you will need.

How many miles are now on the bike? I had not come close to wearing out the rear shoes on my Lance 150 at 10,000 miles and they looked up to another 10,000 when I traded it in.

the brake issue depends on if you have cable or hydraulic.
the first thing i would check is the brake lever itself.
make sure it moves freely in its mount.
second would be the cable (if you have one).
your best bet here is a replacement.
if you have hydraulic brakes then the issue is most likely inside the drum, or in the case of disc brakes the caliper is sticking.
whatever you do, DO NOT get grease or oil on the braking surfaces.
if in doubt about this, then clean with 70% rubbing alcohol, not once, not twice, but 3 times.
the symptoms say you might have cable brakes and water has gotten into the jacket.
or that the cable itself is frayed.
i recommend cable replacement, keeping the old cable and inspecting it.
if the old cable is not worn, then keep it for a backup.

gear boxes are filled with the scoot on the centerstand until the lube starts running out of the fill hole.
fill until lube starts running out, then replace the fill screw.

buy a new tire, do not inherit someone elses problems.
tire sizes are usually designated as x/y-z, replacing the x, y, z, with what is on the old tire.
keep an eye on tire pressure, under or over inflation will reduce the life of your tires.
replace the OEM valve stems, these chinese stems are rotten from the factory.

So I just want to make sure we are getting this clearly. You are saying that your brake becomes stuck and moving or pushing the lever near the back wheel helps you move again? Like if you use your hands, or possibly something else because it gets dirty under there haha, you push the lever that connects the rear brake cable to the rear brake pads/drum area, it comes free and you are able to move?

If that's the issue Remove the rear wheel, and clean out the drum area and brush up the pads with a wire brush. Remove the rod that goes from the lever to the pads and clean and grease it with some white lithium grease. That should keep it from getting stuck for a long time. It is good to clean out this area with brake cleaner, if not available I sometimes use carb cleaner in a pinch but then follow with water and soap and wd40 and an air gun and finally I grease the rod with white lithium grease because it is supposed to hold up to water and weather changes.  

Brandon - Just be mindful that the cost of shipping or even fuel riding any distance to pick up a used tire can cost almost as much as a new one in that size. Your still going to spend money on cleaners, shop towels and rags to clean up the mess from the slime and such too so new or use the cost difference may not be very great and sometime a used even "free" tire can end up costing you much more than a new one. Someone once gave me 4 used tires that looked good for my car however they were old and ended up worn out in a few weeks. It cost me more with lost time from work dealing with the free tires then if I had just bought a set.

Losing time from work to deal with these things also costs you especially if the boss gets upset by it.
