CG125 brake light issue

[CG Sam]

Hi all, I have a 1990 CG and have a slight issue with it, the front brake comes on fine when the lever is pulled, and when the lever is released the brakes are off as you'd expect, but the lever stays in slightly and keeps the brake light on until I push the lever out the rest of the way.

Is this just a case of fiddling with the adjuster thing (sorry don't know the actual name) on the cable by the lever or a bigger problem than that?

is your brake tensioned enough to pull the lever back fully?

you can push the switch inside the brake lever housing so it doenst stick out as much too

an adjustment of the cable might help but I suspect the spring return on the brake arm located on the brake drum might need lubricated as this pulls the brake lever back, also check that the actual brake cable is not seized or has any damage and lubricate as needed.

Thanks for the quick replies, I'll try them both tomorrow. The brake lever can be pulled in fully

Also it may be worthwhile taking the front wheel out and giving the interior of the brake drum a quick service. Once the wheel is removed the brake plate lifts off along with the shoes. You can then remove the shoes, check them for wear while you are it and give them a going over with some sandpaper to roughen up the surface a little.

Then knock out the cam which attaches to the brake arm, you'll have to remove the spring and arm before you can do this; clean the cam and the hole thoroughly and apply some general-purpose grease to the cam and also to the part which holds the shoes and the round peg for the other end of the shoes. Basically any moving parts associated with the braking to stop it sticking. Reassemble it again, don't do what I did and put the speedo drive gear and washer in the wrong way

Apart from that, do what the people above said with regards to to adjustment and spring lubing
For what it's worth the brake lever should not be able to be pulled in fully, it shows the cable is out of adjustment and/or the brake shoes are very worn. Having the bike on it's centre stand with the front wheel off the ground, spin the front wheel and screw the adjustment nut under the wheel spindle until you can just hear the brakes rubbing, then back off half a turn or until it is no longer rubbing (NOTE: due to the shape of the nut can only be turned 1/2 a turn at a time, any less and it pulls the brake arm more and may cause rubbing even when the not fully adjusted. Sucking eggs I know but covering all bases )

Thanks for that, I'll do all that in a few weeks time when I have a bit of time off so won't be using the bike to get to and from work, I'm guessing you've had to do a bit of work on your CG then?

Just went and had a quick play adjusting the cable, can no longer pull the lever all the way back, brake still stops it dead and it springs back fully itself with the brake light going off, thanks for the advice all, I'll lubricate the cable soon though, and check the brakes, although it did pass an MOT a month ago so is it likely they'll be worn?

Thanks for the advice, appreciate it
