• Q: How to replace the hydraulic brake booster on 2005 Chevrolet Astro?

  A: Starting with brake application and drain pan positioning under both the hydraulic Brake Booster and booster reservoir allows for replacement of the hydraulic Brake Booster. Bleed the brake pipes from the master cylinder before separating the power steering hoses and reservoir hose from the booster unit. Reposition the master cylinder while you remove the nuts then disconnect the Pushrod from the Brake Pedal. To begin installation start by removing the hydraulic booster mounting nuts from inside the vehicle before taking out the booster assembly together with the installed gasket. Begin your installation procedure with a fresh gasket before putting in the booster assembly. Secure the booster mounting nuts with torque spec of 36 nm (27 lb ft). After connecting the Pushrod to the Brake Pedal install the master cylinder before setting the master cylinder nuts to 36 nm (27 lb ft). Pathway the power steering hoses into the booster while securing the hose fittings at 27 nm (20 lb ft) torque before joining the reservoir hose to the booster. As the final step, complete a hydraulic Brake Booster bleeding procedure along with a parking brake release.
