How do you adjust the handbrake on a Peugeot 206

..rear disc brake or drum?.

Dont touch the hand brake cables adjustment, get inside the rear brake drums and turn the small cog youll see on a threaded rod affair holding the shoes apart to move them further apart. If you do this untill the drum is too tight to go back on turn the cog back a turn at a time untill it can be reassembled. Al

2nd answer!!!!!!!! Between the front seats where the handbrake is positioned, you have the plastic trim take out the screws that hold the trim in place there should be about 3/4 there is one under the ash try raise the trim up (Do not force it as you might have left a screw in) the 2 adjusting nuts are there to see, jack up the rear of you car put the car in Ist gear & adjust until the brake shoes come into contact with the drums, you can do the job within the hour.
