  Q: How Do You Remove and Install the Brake Booster on Pontiac Firebird?

  A: The power brake unit has no regular servicing but to check the condition of the hoses and the air filter just below the boot of the push rod end. It is necessary to use special tools and skills for the dismantling of the unit and in the event of a defect, it is better to fit a new or factory exchange unit than to attempt to repair a particular booster original. Start by loosening the mounting nuts that hold the master cylinder to the power brake then move the master cylinder aside without stressing the hydraulic lines. If the possible flexibility of the lines is in doubt disconnect at the cylinder and cap the openings. Subsequently, pull the vacuum hose connected to the front of the power brake booster and then plug the ending of the hose. Half turn at least the four nuts fixing the booster to the firewall but do not take them off at this point. In the car, release the clip and withdraw the power brake pushrod from the Brake Pedal but do not force it laterally. After that, turn the four booster mounting nuts and then gently pull the unit from the engine compartment. For assembly, the four mounting nuts should be loosely installed and the pushrod connected to the brake pedal and then the nuts tightened to the required torque again reconnecting the vacuum hose and the master cylinder. If hydraulic Brake Lines were disconnected, the entire brake system should be flushed to remove any air which may have entered it.
