How do you remove a rear wheel drum on a Peugeot expert van?

jack the van up on axle stands.remove the wheel.you will have to leave the van in gear and put something in front of the front wheels to stop the van moving.dont engage the handbrake.remove the wheel place it under the axle as its much cheaper to replace a wheel than an axle should the van fall off the stands.remove the 2 wheel locator pins theese are 11 or 12 mm i think.now you need a hammer and a piece of wood.using the hammer to hit the wood, hit the drum on the inside lip.the amount of force you will use will depend on wheather the drums siezed or not.
