hi all.

Ive got a '96 125 rebel (uk) and my back brake has started playing up. Initialy the brake pedal would stick slightly, i sprayed the lever and linkage with lubricant and it stopped.
However, today the brake locked up under light pressure, and is making a rather odd clunking sound. Luckily this was at low speed so the skid was manageable.
The brake is now fine, but im a bit worried as its now the onset of winter.

Could anyone give any suggestions as to what this could be, and how to fix it with limited knowledge or if il need to take it into a garage.

Many thanks, steve

Can't suggest anything specific, but I would jack the bike up (make sure it's steady) and remove the rear wheel. Check the linkage from the pedal to the drum to be sure it functions properly and do the same with the drum and shoes.

Sounds like the brake pads are worn out allowing the cam to wedge in and stay. My two cents.

I was think cam locking due to lack of lubrication but worn brakes makes sense.

Steve, it sounds like you are going to have to pull that rear wheel.

thanks for the info so far.

Just a few more questions, i cant locate rear pads for the drum brake on a 125, are these the same as the 450?


Also, any tips or general guide on how i take the off the rear wheel,brake system and replace the pads.

Ive got the use of paddock stands and am eager tolearn to do this sort of stuff myself rather than taking it to a garageevery time something happens.


Thanks in advance

Steve

I would think the rear shoes for the 250 drum brake would be closer to the 125, since it is a scaled back model of the 250. You could do a part look up on both bikes and see if it is the same number. No diagrams readily available for the 125 on this side of the pond.

To remove the rear wheel, jack up the bike and support the frame with blocks/jack stands. Do not put pressure on the exhaust while raising or supporting the bike. These are the instructions for the 250 which should be similar or identical to the 125.

1. Remove the rear wheel brake light switch spring from the brake pedal.
2. Completely unscrew the the rear brake adjusting nut.
3. Depress the brake pedal and the brake rod from the pivot joint in the brake arm. Put them back on to avoid losing them
4. Remove the cotter pin, nut, washer and rubber washer from the brake torque link. when the link is free, put them back on to vaoid losing them.
5. On models so equipped, remove the cotter pin from the rear axle nut. Discard pin and use a new one when reassembling.
6. Loosen the rear axle nut.
7. Loosen the drive chain adjuster locknutss.
8. Loosen both drive chain adjusting bolts or nuts.
9. Push the wheel forward until the chain is loose.
10. remove the rear axle nut and pull the axle out from the right side (may be left on your model, not sure).
11. Slip the chain off the driven sprocket and pull the the wheel to the rear of the swingarm.
12. Install by reversing these steps.

Torque on the rear axle nut is 58-72 ft lbs, 80-100 Nm
" brake torque link nut 14-18 20-25

After the wheel has been reinstalled, rotate it and apply the brake several times to be sure it rotates freely and the brakes work properly.

Brake disassembly is pretty straightforward.

All this information is contained in the service manual. Investing in one will save you a lot of money in facilitating repairs.
