Weak rear brakes

[306Puggy]

You need to adjust the rear drum adjusters, as long as the cylinders are not leaking. It might also be worth using a rough grade of sandpaper to lightly sand the shoes and inside surface of the drum but you don't want to go too hard and create uneven surfaces. Have a look on the MOT checklist for a picture of the rear drum's components. You will need a 32mm socket to undo the hubnut. Don't forget to release the handbrake or the drum won't come off.
