What Is a Proper Way to Replace a Brake Booster?

The first step in replacing a brake booster is to gather a socket wrench, a tube nut wrench, brake fluid, a jack and its stand, and the new brake booster. Next, the car owner must steady the car by lifting it with a floor jack to remove the tires to get better access to the vehicle's brakes. He must use the jack stand to ensure the car remains steady for the rest of the procedure.

After removing the tires, the owner can use a socket wrench to open the metal cover previously obscured by the tires to access the master cylinder. Next, he must use a tube nut wrench to loosen the tube nuts that connect the brake lines to the master cylinder. Afterwards, he can use an open-ended wrench to remove the lines from the cylinder.

The owner uses a socket wrench to take out the master cylinder and inspects it for leaks and damage. Next, he loosens bolts connecting the master cylinder and brake booster and then unbolts the nuts connecting brake booster to brake pedal.

The next step is to disconnect the booster from both the brake pedal and vacuum hose and to remove any bolts connecting it to the firewall. Then, the owner separates the booster and cylinder. Now, he can secure the new booster to the firewall with the appropriate nuts and bolts. Afterwards, he replaces the nuts and bolts to reconnect the brake booster and pedal.

He then reconnects the master cylinder and brake lines into position and then connects the cylinder to the new booster. Finally, he places the tires back on the vehicle, completing the procedure.
