remove rear wheel , pull off the brake drum , you may have to use two flat blade screwdrivers one eachside to prize the drum off,clamp the flexable brake hose behind the brake assembly so fluid does'nt drainout,at the rear of the back plate you will need to disssconnect the hand brake cable usually a spring needs compressing by hand and then are able to disconnect the cable from its seating,take a picture of the brake shoe assembly before dismantling it so you know where the components go when re building, there will be spring loaded pin holding the shoes in place ,with a pair of pliers push and twist the flat washer so the pin head comes through the retaining washer you should then be able to lift away the shoe's and mechanism , next at the rear of the cylinder disconnect the brake pipe and the two retaining screws , fittings is the reverse , if you can get a workshop manual for the vehicle this will give step by step guide a tips for that exact vehicle, once back to gether unclamp the brake hose and bleed the brakes , take your time and if not sure if it looks right have a look at the picture or alternatively take the other wheel and drum off to check good luck

The rear drum brakes:

• Have internal shoes that expand against the brake drum (1126).
• Are a single-anchor type.
• Are actuated by one rear wheel cylinder (2262).
• Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
• Adjust rear brake shoes and linings (2200) automatically.
• Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.

When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .
