Q: How to install the rear and front Brake Lines on Scion xB?
A: The installation of rear brake flexible hose begins by attaching it with the bolt and new clip under a torque of 19 Nm (194 kgf-cm, 14 ft-lbf). Installation of the front brake flexible hose starts by positioning its identification marker inside the vehicle while reducing hose twists until the clip achieves full seating. When using a union nut wrench to assemble the brake tubes and flexible hose you should use it to tighten with force of 14 Nm (143 kgf-cm, 10 ft-lbf). However without the wrench apply 15 Nm (155 kgf-cm, 11 ft-lbf). The correct torque can be achieved if you use a torque wrench with 300 mm (11.8 in.) fulcrum length together with a parallel union nut wrench that has a 22 mm (0.886 in.) fulcrum length. Begin by installing the flexible hose on its union bolt with a new gasket where the torque reaches 29 Nm (296 kgf-cm, 21 ft-lbf) before secure a new clip in place. A union nut wrench should be used to attach the brake tube to the flexible hose as the wrench holds the hose steady then applying identical torque measurements. Installation process includes filling the reservoir with brake fluid followed by master cylinder bleeding then bleeding the brake line and bleeding the brake actuator and checking the reservoir fluid level together with brake fluid leak inspection and ending with rear wheel installation at 103 Nm torque (1050 kgf-cm, 76 ft-lbf).
Q: How to install the rear Brake Line and ensure proper torque specifications on Scion xD?
A: Before installing the rear brake flexible hose users must place two new clips onto the axle beam. By using a union nut wrench you should tighten the 2 brake tubes onto the flexible hose with 15 Nm (155 kgf-cm, 11 ft-lbf), but the torque value with a union nut wrench should be 14 Nm (144 kgf-cm, 10 ft-lbf). The required torque value can be reached with a torque wrench measuring 300 mm (11.8 in.) in length where a separated by a 22 mm (0.866 in.) union nut wrench should maintain a parallel position to the torque wrench. Brake fluid should be added to the reservoir before performing master cylinder bleeding and sequential bleeding from brake line to brake actuator (including VSC features). Ensure to inspect the reservoir fluid level after installation while conducting a brake fluid leak inspection. To install the rear wheel apply final torque of 103 Nm (1050 kgf-cm, 76 ft-lbf).
