How to Remove Oil From Brake Shoes

A vehicle's brake system uses hydraulics to engage and disengage the brakes. Over time, the seals containing this oil might become weak and start leaking fluid. On drum brakes, this typically means the brake shoes become covered with this oil. When oil seeps into the the brake shoes, it weakens them and can crack the shoe's friction material. Prevent this by catching the leak early, then thoroughly cleaning the fluid from the shoes and surrounding area.

Instructions

1

Loosen, but do not remove, the lug nuts from the wheel that corresponds to the shoes that need to be cleaned, using a ratchet and socket.

2

Raise the wheel from the ground, using the floor jack. Secure the vehicle by placing floor jacks beneath it.

3

Remove the lug nuts and pull the wheel from the vehicle.

4

Pull the drum (the large metal object directly behind the wheel) from the vehicle with your hands. A light tapping with the rubber mallet will help loosen the drum if it is stuck.

5

Place the drain pan directly beneath the brake system.

6

Cover the wheel cylinder (the small hydraulic component at the top of the brake system) with a plastic wrap to protect its rubber components from damage.

7

Spray the brake shoes and all of the mechanical brake components with the brake parts cleaner. Lightly scrub the components with a soft-bristled brush.

8

Repeat Step 7 until the entire drum brake system is free of all oils.

9

Repeat Steps 4 through 8 for any other shoes that need cleaned.

10

Remove the plastic wrap from the wheel cylinder and place the drum back on the brake system. Press the drum until it fully seats on to the brakes. A slight wiggling motion might help.

11

Place the wheel back on the vehicle and hand-tighten the lug nuts.

12

Remove the jack stands from under the vehicle and lower it to the ground.

13

Tighten the lug nuts to the specifications listed in your owner's manual, using a torque wrench and a socket.

14

Pour the fluid in the drain pan into the empty container and dispose of it properly. Many auto parts stores will take old fluids free of charge.
