2010 Scion xB Brake Master Cylinder Parts Questions & Experts Answers

• Q: How to install the brake master cylinder on 2010 Scion xB?

  A: The brake master cylinder installation starts with push rod check and adjustment of the brake booster under no vacuum conditions through brake pedal repetitive depressions with the engine off. The new brake master cylinder accessory tool should have chalk placed on its tip before being set on the brake booster assembly to measure the push rod clearance against the accessory tool which must measure 0 mm (0 in.). If the specified clearance between push rod and accessory tool is not attained then adjust the push rod length with Special Service Tool: 09737-00020 and a socket driver sized for 7 mm (0.28 in.) You should install a new O-ring on the brake master cylinder sub-assembly before installing the sub-assembly together with its wire harness clamp bracket using 2 nuts that require 13 Nm (127 kgf-cm, 9 ft-lbf) torque. The installation of 2 brake tubes onto the brake master cylinder sub-assembly should use a union nut wrench with parallel alignment and torque to 15 Nm (155 kgf-cm, 11 ft-lbf) without the wrench or 14 Nm (143 kgf-cm, 10 ft-lbf) when the wrench is present. Place the harness clamp on the wire harness clamp bracket then mount the wire harness onto the brake master cylinder sub-assembly before making the brake fluid level warning switch connector connection. Connect the tubular reservoir of the clutch system through its clip for manual transaxle models. Fasten all components starting with the air cleaner assembly followed by the outer cowl top panel, front wiper motor with its link, the cowl top ventilator louvers for left and right halves, the hood to cowl top seal, both front wiper arm and blade assemblies and the windshield wiper arm cover. The brake fluid reservoir needs to be filled with the correct fluid before bleeding the master cylinder combined with brake lines and actuator and checking the reservoir fluid level while inspecting for brake fluid leakages.
