Removal of a Power Brake Booster

The power brake booster on a car or truck uses vacuum power from the engine to apply added pressure to the brake master cylinder. This makes braking easier and allows you to apply more pressure to the brakes. If the power brake booster goes out, then it becomes difficult to stop your vehicle, and you could potentially get into an accident. Before you can replace the power brake booster, you first have to remove the old one from the vehicle.

Instructions

1

Pop the hood of your vehicle Locate the rubber vacuum line running to the brake booster on the driver's side of the firewall. Pull the vacuum line off of the brake booster or, if necessary, use a flat head screwdriver to remove the hose clamp holding the line in place.

2

Unbolt the brake master cylinder from the power brake booster with an open-end wrench.

3

Look underneath the dashboard and locate the rod that connects the brake booster to the brake pedal. Remove this connection with a 3/8-inch ratchet and socket or a flat head screwdriver to take off the clip.

4

Unbolt the power brake booster from the firewall with the 3/8-inch ratchet, extension and sockets and a 3/8-inch universal joint. Go underneath the hood and pull the brake booster forward and off of the firewall until the rod clears the firewall. Then pull the brake master cylinder off of the booster and remove the booster from the vehicle.
