You don't need to remove the pedal to get the booster off,it just slides inside,so when the booster is unhooked it will just pull out.

How to replace brake booster on 2005 Pontiac aztek


Step 1 - Locate the Brake Booster The brake booster is located adjacent to the master cylinder. There will be 4 mounting screws protruding through the booster. The booster is also attached to the brake pedal in the interior of the car. This is where you will start work in replacing the brake booster.
Step 2 - Remove the Brake Booster Start by locating the booster rod that goes through the firewall and is attached to the brake pedal on the interior of the car. Typically, there is a cotter pin that secures the rod to the pedal, but there may also be nuts. When removing any fasteners in the course of this job, make sure to retain the nuts, cotter pins, and various other fasteners as the new brake booster will not come with replacement fasteners.
Remove the fasteners, whether it is a cotter pin or nuts. Slide the rod off the brake pedal. Disconnect the vacuum brake line that connects to the booster. In the engine compartment, there are four bolts securing the booster to the master cylinder and firewall. Loosen and remove these nuts. Remove the nuts (there are usually 2 in addition to the 4 that have already been removed) that secure the brake booster to the master cylinder. Wiggle the brake booster away from the master cylinder. There is a seal between the two. You will need to keep this as the new part does not generally come with another one. Remove the brake booster.
Step 3 - Install the New Brake Booster Set the new brake booster on the four mounting screws. Tighten the nuts on the bolts to the master cylinder. Insert the push rod through the firewall. Start these by hand so that the threads are not ruined. Reattach the vacuum hose, then the nuts to the 4 mounting screws. Reattach the push rod to the brake pedal by whatever means it was originally secured with, whether by cotter pin or by bolts.
Step 4 - Bleed the Brakes You will need to bleed the brakes after replacing the brake booster

How do you disconnect the brakebooster rod from the brake pedal on a 1998 4x4 z71chevy truck? how do you take the plastic conector off?? pics would help


  1. Remove the master cylinder from the brake booster. Use line wrenches and remove the brake lines on the master cylinder. Disconnect the electrical connector. Remove the nuts holding the master cylinder to the brake booster and remove the master cylinder. Lay it down with the line holes up to prevent leakage. The brake activator rod must be removed next---this is attached to the top of the brake pedal arm.
  2. There are two types of brake light switches. One is mounted remotely and has a button that is depressed by the brake pedal when it is released that creates an open circuit and turns the lights off. When the brake pedal is depressed, the button is released and allowed to extend, creating a completed circuit and turning the brake lights on. These are adjustable. All that needs to be done to adjust these switches is to adjust them where they are making contact with the arm of the brake pedal when the pedal is released. The second type is a switch that is directly attached to the brake pedal where the activator rod and pedal arm are attached with a through pin.
  3. Remove the bottom portion of the driver's side dash to gain access to the activator rod. Remove the clip or spring lock from the side of the pin holding the activator rod to the brake pedal. Disconnect the electrical connector to the brake light switch. Rotate the switch upward and dislodge the brake activator rod from the brake pedal arm. Remove the electrical switch. Using a long 3/8-inch drive extension with a swivel and a 15 mm socket, remove the four nuts under the dash on the firewall holding the brake booster to the firewall. Unplug the vacuum line to the booster and remove the vacuum booster from the firewall.
  4. Install the new booster, keeping the brake activator rod on the inboard side of the brake pedal arm. Go under the dash and install the nuts retaining the booster to the firewall and tighten. Install the brake switch over the brake pedal. Hold the electrical end up while the activator rod is pulled and inserted over the retaining pin on the brake pedal arm.
  5. Install the retaining clip on the retaining spring and connect the electrical connector to the switch. Install the lower dash panel. Install the vacuum hose to the brake booster. Install the master cylinder and tighten the nuts. Install the brake lines to the master cylinder and attach the electrical connector. Check the brake fluid level in the master cylinder and fill as necessary.
  6. Have someone sit in the car while you loosen the front brake line on the master cylinder. Have the person helping push the brake pedal to the floor and hold it there. Once the pedal is to the floor, tighten the brake line and repeat the procedure for the rear line. Recheck the level in the master cylinder and fill with brake fluid as needed.
