CG125 Brake lever adjuster

gezza2k

Hi, I have searched everywhere but got nowhere so hopefully someone here might help.

I have got CG125 which went for its mot and got an advisory for little reserve travel on front brake lever. (06 disc brake model)
The mech seemed to fix it but I noticed yesterday the brake is binding on the wheel so it seems its too tight. wheel squeaks

I have searched everywhere on how to slacken the brake cable but found nothing.

As anyone here got a suggestion. Thx

I'm not familiar with the bike, but is it a cable-operated disc brake? If so, there must be some way of adjusting the cable to allow for pad wear. Look for some kind of screw and locknut arrangement somewhere between the lever and the brake caliper. I would have thought it most likely at the lever end, but I had a Honda with an adjuster half-way down the cable, hidden where it went between the headstock and tank.

When you find it, slacken it off until the wheel turns freely, and then re-tighten until you have about 5 mm of free play at the lever before the cable starts to move. If you slacken the cable and the wheel is still binding, then you have a sticky caliper, which will need to be taken off and cleaned up.

Sorry can't be more help than that. Feel free to post an update and I'll see if I can help further.

Thanks Mate, Will have a look tomorrow.
It cant be the caliper because it was working perfect before the mot.

will post back when I find the adjuster

I've had a quick look on the web, and all the CG brake info I can find is about hydraulic brakes. TBH, cable-operated discs are quite rare these days. Can you check if it has a cable or a master cylinder and hydraulic pipe, and post back here? Obviously, any advice would depend very much on the type of braking system.

My old CG had cable/drum brakes and I have to say that 5mm free play at the lever is far too much for that model - any mechanic who ever commented on it said to set it for barely any play at all - 2-3mm max. It never failed an MOT!

This dealt with all drum lag/fade and helped braking no-end. I could stop that little bike on a button and was very glad I could!

Have you found a brake cable?. Disc brakes normally have hydraulic pipes.

Its hydraulic I think, no cable.

Pads or caliper may be sticking or hydraulic seal fault. Ask the mechanic. A front brake service will be cheaper than an accident.

Cg125's have had hydraulic disks fitted for a long time and they were uprated to 240mm in 04

Best bet is to read through this

If in doubt, get it done by a professional who knows what they are doing. What part of the country you in?

its going in shop for a tyre fitting so will get them to look at it as well.
Only happened the morning after it went for its mot, I noticed there was less slack on the lever when I picked it up so I don't know what they did.

If it's hydraulic there really shouldn't be any slack at all, it should adjust itself. If it's more firm than before and less spongy then there was probably a bit of air in the system and the mech bled it out and added more fluid. The sticking *may* be down to having a bit too much fluid in the system and it not letting the piston out but I doubt it.

More like it is a coincidence and down to a sticking piston. Not saying you haven't but always clean the brakes now and again with water or brake fluid cleaner to prevent corrosion; especially if you've ridden on salted roads in the winter.
