• Q: How to install the brake master cylinder on 2008 Toyota Prius?

  A: Install the brake master cylinder by attaching the push rod clevis to the brake master cylinder followed by locking the nut while torquing it after brake pedal height adjustment. Use lithium soap base glycol grease to treat 2 new grommets before installing the No. 1 master cylinder union with the 2 grommets to the master cylinder by screw means and torque them up to 1.8 Nm (18 kgf-cm, 16 in-lbf). Special Service Tool: 09023-00101 enables the installation of brake tube together with 2-way to the brake master cylinder which requires torque of 15 Nm (155 kgf-cm, 11 ft-lbf). Attach the brake master cylinder to the bracket and tighten the 2 nuts to 13 Nm (127 kgf-cm, 9 ft-lbf) while installing the gasket between them. The connection between the No. 2 front brake tube and brake master cylinder and clamp requires Special Service Tool: 09023-00101 for torquing up to 15 Nm (155 kgf-cm, 11 ft-lbf). The same tool is needed to connect the No. 1 front brake tube and achieve the same torque setting. Insert the bolt to the actuator bracket while applying torque to 5.0 Nm (51 kgf-cm, 44 in-lbf). Ultimately add and secure the reservoir tube hoses with four clips. The brake master cylinder push rod pin should link the push rod clevis to the brake pedal before installing the clip and brake pedal return spring. The first step is to install the inverter with converter before adding the outer front cowl top panel using 7 bolts that require torquing to 6.4 Nm (65 kgf-cm, 57 in-lbf). Afterward, install 3 clamps to the panel. Use 2 bolts to install the engine room No. 2 R/B while torquing them to 8.4 Nm (86 kgf-cm, 74 in-lbf). Following this fit the windshield wiper motor and link assembly together while you should perform fluid installation into the brake reservoir followed by extracting master cylinder and stroke simulator air. The technician must perform brake fluid leak inspections while checking the reservoir fluid level along with brake pedal height adjustment and free play and reserve distance checks. The last steps involve installing the lower instrument panel finish panel together with the No. 1 instrument panel register assembly followed by performing the brake system initialization and checking and clearing the DTC.
