On The rear if you have drums
Remove the wheel and tap the drums at back with a 'deadblow' hammer, rotating the drum as you do this. The brake shoes tend to hold drums on.
If you are inexperienced, you should not be messing around with the brake drums.
brake drums should pull off if not rusted on.
Remove the wheels, pry the drums off.
Remove the drums and take them to an auto parts store that has a brake drum lathe.

Remove the wheels from your 1995 Toyota Camry. Remove the brake pads by removing the brake pad Springs. Tap on the brake drum with a hammer or mallet. Slide the brake drums off. Reverse the process to install the new brake drums and shoes.
experience and a big hammer
best answer is take it to a brake shop it's not something that should put your life on the line for. but if you have to do it you will need a Chevy brake tool or an Allen wrench to remove the calipers then its simple to switch out pads. drums again I recomend a shop.
