2005 Ford Focus Brake Booster Parts Questions & Experts Answers

• Q: How to service and repair the vacuum brake booster on 2005 Ford Focus?

  A: The service and repair of the vacuum brake booster requires first removing the Hydraulic Control Unit (HCU) and disconnecting the speed control actuator electrical connector. The bolts securing the speed control actuator need removal before setting it to the side. PZEV vehicles need the removal of the evaporative emission canister purge valve. The brake master cylinder needs removal after detaching the pin-type retainer and cowl heater hose bracket. Detach electrical connectors by twisting them loose before discarding the switches. This procedure includes the speed control deactivation switch (when available) and stop lamp switch together with Clutch Pedal Position (CPP) switch for vehicles equipped with manual transmission. A new actuating rod pin must be installed before disconnecting the brake booster actuating rod from the brake pedal by using the brake pedal while disengaging the tab followed by discarding the old pin. The technician must inspect brake booster gasket alignment and actuator rod positioning through the bulkhead rubber boot before installing the brake booster by removing its retaining nuts. The work ends by reversing brake system assembly while performing braking system bleeding.
