2009 Ford Focus Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to remove and replace the brake master cylinder on 2009 Ford Focus?

  A: Before removing the brake master cylinder start first with the engine off and activate the brake pedal multiple times to decrease brake booster vacuum. First remove the battery tray together with the cap before you utilize a suitable clean suction device to extract brake fluid from the reservoir. First reverse the Battery Junction Box (BJB) screw, remove the bracket then disconnect the BJB before positioning it to the side while pressing the locking tab. Use caps to seal hose connections to prevent fluid losses along with separating the brake fluid reservoir-to-master cylinder tube. To remove the transmission vacuum in manual transaxle vehicles one must detach the clutch master cylinder tube. Brake fluid loss needs prevention through the usage of caps before disconnecting brake tube fittings with either 20 Nm (177 lb-in) torque setting for antilock brake-free vehicles and 15 Nm (133 lb-in) for vehicles that contain antilock brakes. To remove the master cylinder from the booster select the master cylinder-to-booster seal. Afterward discard the brake master cylinder nuts together with the vacuum seal. The installation requires new nut tightening to 18 Nm (159 lb-in) and constant verification that the vacuum seal fits correctly on clean mating points. Install new components along with bleeding the brake system while following it with manual transaxle vehicle hydraulic clutch system bleeding according to procedure. Use clean brake fluid at all times which follows manufacturer specifications to stop system contamination and avoid damage and perform immediate water washing of brake fluid drips on painted or plastic surfaces.
