How do you remove rear brake drum on a citroen 2cv?

Answer 1

First thing, before you even start, you need to spend some money. A couple of things need replacing.

Rear wheel drum retaining nut - 44mm

Socket for said nut

probably a 3/4 to 1/2" drive adaptor for said nut

Long bar - ideally 3/4 inch + steel bar - you may well need to stand on it - or impact wrench, a manual one will almost certainly not be able to do the job

Hammer

Punch

Centre for nut - metal one's are no longer available, buy a plastic one. Don't try and refit the metal one, it will never be dirt or watertight once it is off.

beware - the torque is huge!

Prise out centre cap using a flat screwdriver.

Nut is peened into a groove in the shaft, hit the peen out with a hammer and punch until it looks like the nut will move.

Apply pressure using whatever method you like, you may well need the bar, an extension piece and you to stand on the end.

You will need to replace and torque the nut afterwards, peen it in and replace the cap
