delayed rear drum brake release

[czakal]

Hello,
I'm having a problem with my rear drum brake on my Kymco Pulsar 125 (mostly like a CG125). The rear brake pads take a moment to fully release when I use it (the brake pedal appears to return completely but the pads are still dragging and usually make a squeaking noise). As the problem disappears some time after I start my trip, I'm not able to recreate it when I finish my trip to troubleshoot. What causes the rear brake pads to not release right when you lift your foot off the lever?
Thanks for your help,
Seb

Probably just needs a good clean out. Brake dust builds up in the drum and can cause such problems. Use a tiny bit of grease of the cam (the bit that turns and pushes the shoes apart, just a wee dab in between the shoe and the cam face - you don't want it to contaminate the pad surface)

Thanks, I haven't disassembled a brake before. Guess there's a first time for everything!

If you can take the wheel off you can do that. Other thing it could be is corrosion around the shaft of the cam. Again a clean out and a little lube in there. Loosen the bolts holding the actuator arm on before you take the wheel off. If they're still it's easier whilst the whole assembly is still mounted.

pads suggest disc brakes

Sticky, corroded cam freeing off when it gets hot from use.

Strip, clean, re-lube.

I took mine off the other day, piece of piss. Just go around everything with some brake cleaner and then anything sized/stiff that shouldn't be, wd40 it till it's not, then grease it till it's smooth, then put it back together, may be worth replacing your shoes whilst you are in there, depends whether you can be asked to take it all apart again later down the line. For the sake of 18 quid I replaced mine whilst un seizing it.

Aslong as you have the tools (socket set, torque wrench if you don't trust yourself) and the lube, then you just need to watch a couple of videos on YouTube and you are set

High melting point, which is a pretty standard grease

Shell Gadus, V220c. Anything that turns on a bike and needs greasing will be fine with it. The grease fairy in work brings mine. Otherwise, a fiver on ebay will get you a tub that will probably outlast the bike, and possibly you, if you seal it properly when done using it.
