  Q: How to replace the vacuum brake booster on Chevrolet Classic?

  A: Start replacement of the vacuum Brake Booster by detachment and placing the underhood electrical center out of its holding position. Carefully take off the master cylinder from its position on the hydraulic Brake Booster while maintaining the booster-exiting insulator in place. Separate the vacuum Brake Booster assembly by disconnecting its hose and valve connections before taking out the left closeout/insulator panel. Loosen the vacuum booster retaining nuts before working the booster pushrod off the Brake Pedal clevis pin without putting too much side pressure. Attach the new booster to its location after installing it and hook up the booster pushrod to the Brake Pedal. Tilt the booster slightly while you align the pushrod with the pedal clevis pin and assemble without pressuring the booster from the side. Secure the booster retaining nuts at 27 nm tension before putting back the left closeout/insulator panel. Start by linking the vacuum hose unit with the vacuum Brake Booster check valve to the booster as a single assembly before setting the master cylinder onto the booster and finally installing the master cylinder itself. Stand the underhood electrical center bracket in position and reconnect all parts of the underhood electrical center.
