2007 Ford Focus Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to service and repair the brake master cylinder on 2007 Ford Focus?

  A: Before servicing the brake master cylinder you must remove the battery followed by disconnecting the electrical connector from the brake fluid reservoir filler cap through pulling back its tab and pressing the clips. Clean the filler cap opening before removing the reservoir cap and empty the reservoir by using a sanitary suction device to reinstall the cap afterward. The service begins with disconnecting the battery junction box (BJB) electrical connectors before removing the BJB screw and placing the BJB to one side. Before disconnecting the brake fluid reservoir-to-master cylinder tube, users should cap its hose connections to stop fluid loss and block dirt contamination. Before removing the clutch master cylinder tube connections from manual transaxle vehicles you need to install caps on them. Any vehicle without anti-lock brakes requires disconnection of the brake tube fittings which must get tightened to 20 Nm (15 ft. lbs.) during reassembly. The brake tube fittings on anti-lock brake vehicles require 17 Nm (13 ft. lbs.) torque when you reinstall them. A proper vacuum purge of the booster must proceed master cylinder removal by removal of the brake booster vacuum hose. Remove both brake master cylinder nuts and brake master cylinder from the vehicle while installing this part at 20 Nm (15 ft. lbs.) tightness. After verifying that the vacuum seal is correctly placed it is important to inspect the mating surfaces for cleanliness before master cylinder installation. Perform the reverse steps of removal while doing the required brake system bleeding steps. The use of DOT 3 brake fluid is mandatory for brake component safety while immediate liquid dispersion with water remains necessary for protected painted or plastic materials.
