Drive and park your golf cart on a level surface. Turn the cart off but do not set the parking brake. Instead, place blocks in front of and behind the front wheels to prevent rolling.
Place the 3-ton jack underneath the center rear of the cart and lift it into the air.
Take your 3/4-inch socket wrench and remove the lug nuts holding the two rear wheels onto the body. Place the wheels to the side.
Remove the break drum, which covers the brake pads. Remove the cotter pin (some carts have two) using needle-nose pliers.
Discard the worn-out pads. Apply an anti-squeal grease to the interior of the new pads. Insert the replacement pads and secure them, using the cotter pin(s) and the brake drums.
Put each of the rear wheels back on the cart and secure them, using the lug nuts and socket wrench.
Lower the jack and remove the blocks from around the front wheels.
Test the cart's new brakes at a slow speed on the level surface.
