  Q: How to service and repair the vacuum brake booster on Ford Thunderbird?

  A:

  Service and repair of the vacuum brake booster starts with removing the Wiper Arm nuts and wiper arms before disconnecting the washer hose to remove the cowl cover through pushpin and rubber trim removal. The service requires first removing the vacuum hose bracket nut and setting it aside followed by unbolted removal of the cowl brace center and end bolts to extract the bracket. The service begins by disconnecting the Coolant Reservoir return hose and succeeding with the Brake Master Cylinder removal. First disconnect the electrical connector if needed then separate the power brake booster check valve and proceed to take out the coolant reservoir bolts and the Radiator to engine vent before removing the coolant reservoir. First separate and uninstall the Brake Pedal pin along with the clip before you extract the nuts from the power brake booster and remove the component itself. Reattach the power brake booster into its proper location then fasten it securely by tightening the booster nuts. Reset the brake pedal pin together with its clip after installing the coolant recovery reservoir bolts and joining its connecting hose to the reservoir. Connect the power brake booster electrical connector only when necessary before installing the power brake booster check valve along with the coolant reservoir return hose. After installing the brake master cylinder you should attach the cowl brace end bolts then move on to the center bolts before tightening the vacuum hose bracket nut. The last steps involve replacing the cowl cover, rubber trim and pushpins while reconnecting the washer hose then securing wiper arm nuts and bleeding the brake system before checking the coolant level for necessary filling.
