BMWs have used 4 wheel disc brakes since at least 1985, so you don't need to worry about all that stuff concerning drums and shoes. It will be the same as the front, with one small exception. On some cars when replacing rear pads, you need to screw the caliper piston back in. You will need a special tool for this, but any auto parts store will let you rent or borrow one. You cannot just squeeze it back in like the fronts.

The only drum and shoes you will find are if you want to replace or check the parking brake. The rear disc comes off and inside of it is the drum and shoes for the parking brake.Changing the back brake pads on a BMW 318i 1999 E46?
if you have the right tools and are mechanically minded, then it is not too bad a job to do.you need to jack the car up,(ensure you use axle stands for safety),remove the wheel.you will see one or two screws holding the drum on. remove these and take the drum off.if it wont come off,tap all round it gently with a hammer and this should release it.when drum is off,take the large spring out of the hole at the top of the brake shoe.repeat with the lower spring,noting which way they are inserted.also note how the fork is situated between the opposing shoes(a piece of metal at the bottom of the brake shoes).you will see two small metal cups with springs below them in the middle of each shoe.use a pair of pliers to push these in and twist to remove them,careful not to lose them.prise the shoes out of the piston grooves at the top of the hub,and lift them out of the bottom grooves.replacement is the opposite. if you don't fancy this yourself, go to a garage.brakes will feel slightly spongy for a while afterwards, this is normal till the shoes 'bed in 'properly. hope this helps.Changing the back brake pads on a BMW 318i 1999 E46?
There is no special tool used to push the caliper pistons back in to the caliper as noted. They are the same as the front. you need a 7 mm allen key to remove the sliders and a pair of mulitgrips to push the piston in, a large flat blade screw driver to remove the anti rattle clip. Dont forget to change the pad wear sensor as well of the dash lamp will not go out.
