Question 1

How to replace the power vacuum brake booster on Buick Enclave?

Accepted Answer

Park the vehicle on a flat spot and put the parking brake on before you began working. Before starting the replacement press and release the brake pedal until it becomes hard to use all the vacuum reserve. Take out the air filter assembly and the windshield washer solvents container from its compartment. Detach the master cylinder fluid level sensor electrical connection before removing the vacuum Brake Booster's check valve and hose units along with its vacuum sensor. Move the 2 brake pipes free from their routing clip on the frame rails. Then take off the bpmv valve's 2 nuts without disconnecting the pipes. Move the bpmv assembly forward when above the studs before removing its 2 master cylinder nuts yet keeping brake tubes connected. Set the master cylinder assembly on mechanics wire stands to maintain its upright position. Uninstall the left panel insulator and driver knee bolster from their places. Disconnect the brake pedal pushrod components by removing the clip and clevis pin. Take away the steering module and secure the 4 Brake Booster bolts. Shift the vacuum Brake Booster up and forward for the mounting studs to exit underneath the dash panel before you detach the vacuum Brake Booster. Check the vacuum Brake Booster gasket for damage against the dash panel and replace it when necessary. Thread the mounting studs of the vacuum Brake Booster onto the dash panel and fasten it with 4 nuts tightened to 25 nm (18 lb ft). Fit the intermediate Steering Shaft back in place and attach the brake pedal pushrod to its pedal base before setting the clevis pin with its retaining clip. Closely fit the driver knee bolster and left panel insulator so the master cylinder seal connects correctly with the vacuum Brake Booster while checking for damage. Check the Brake Master Cylinder seal connection to the vacuum booster unit and replace if detected damaged before installing both Brake Master Cylinder nuts at 20 nm torque. Carefully place the bpmv assembly over the studs while installing both bpmv nuts to their bracket. Tighten them to 20 nm (15 lb ft). Reattach the brake pipes through their path to the frame rail routing clip before reconnecting the master cylinder fluid level sensor power connection. You should attach the vacuum Brake Booster vacuum sensor and vacuum Brake Booster check valve and hose assembly to their proper positions on the vacuum Brake Booster. Put back the windshield washer solvent heater and the air cleaner unit last.

Question 2

How to Ensure Proper Installation of a Brake Booster on Buick Regal?

Accepted Answer

The power Brake Booster holder j22805-b should be your first tool to gather. Take off the left side instrument panel insulator and detach the stoplamp switch electrical connector. First take off the pushrod retainer and separate the Brake Booster pushrod from the brake pedal. Then remove the cross vehicle brace and fuel injector sight shield. Unplug the Brake Fluid Level Sensor using proper tools but keep brake pipes attached to the master cylinder. Unthread the two retaining nuts and properly place the master cylinder away. Unplug the vacuum Brake Booster check valve assembly and keep it together with the vacuum hose as you disconnect it. Unplug the throttle and cruise control wires from the Throttle Body before taking out the throttle bracket together with throttle and cruise control cables. Move the motor to its ideal position before pulling apart the EGR Valve wiring harness shield and its associated components. Take off the transmission fluid filler tube bracket retainer and secure the filler tube during work. Place the j 22805-b holder over the Brake Booster then affix it with master cylinder locking nuts. Gently unlock the booster from the cowl front and turn the booster counterclockwise with a flat-bladed tool while rotating the power Brake Booster holder (J 22805-B). Remove the vacuum Brake Booster. To install the new vacuum Brake Booster, place it on the cowl with locking flanges engaged and turn clockwise using a ratchet on the power Brake Booster holder (J 22805-B) without using any flat-bladed tools. After installing the power Brake Booster holder (J 22805-B) you can take it out of place. Place back the transmission fluid filler tube bracket keeper then adjust the filler tube and heat shield of EGR Valve wires. Secure the heat shield bolt and nut to 10 nm torque. Lower the engine back to its factory position and attach both engine mount struts on their left and right sides. After placing the throttle assembly in its correct position you can install the cables to the Throttle Body. Reattach the vacuum hose and check valve to the booster unit then place the master cylinder on top before tightening its retaining nuts to 25 nm force. Connect the brake fluid sensor power wire while also placing the fuel sight shield and cross vehicle frame support before joining the brake pushrod to the pedal with its clip. Complete the process by connecting the stoplamp switch and putting back the instrument panel cover.
