The Toyota Venza was made to be something between a car and a SUV. Engineers at Toyota started with the Camry platform, but improved the brakes with larger rotors, dual piston calipers in the front and a more advanced ABS and stability control system.
The maximum allowable lateral runout for the front rotors is only .002˝. In the rear, the maximum allowable lateral runout is .006˝. The service information recommends having all five lugnuts tightened to 76 ft/lbs before making a measurement with a dial indicator.
Pads And Calipers
The front brake pads use spreader clips to push the pad away from the rotor. These clips help to reduce drag and eliminate noise.
The calipers in the front and rear use guide pins. The boots are critical to the health of the pins. If the boots are damaged, moisture can enter into the cavity and corrode the pin. This contamination will eventually cause the caliper to seize.
Lubricating the pins is critical for making the brake job last. A brake-caliper-specific grease is recommended. Toyota recommends applying a light coating to the body of the pin and the sealing surfaces of the boots. If too much grease is used, it will expand and possibly dislodge the boots from the lip on the caliper bracket.
The Venza has an advanced ABS and stability control system. The system also controls electronic brake distribution and has a brake-assist feature to help the driver produce enough hydraulic force during a panic stop.
Pressure bleeding is recommended for removing air from the base brake system. If you are planning to perform a manual or pressure-bleeding procedure, never have the ignition on or the engine running during operation. Codes might be stored for a sudden loss of hydraulic pressure. If you are bleeding the ABS or master cylinder, use a scan tool to actuate the valves in the ABS HCU to remove all the air.
The Venza uses a drum-in-hat parking brake. The parking brake is applied using a foot pedal. Toyota specifies the pedal should fully engage after four to six clicks with moderate force. If it does not, you need to adjust the clearance between the parking brake shoes and hat.
The first step is to remove the nuts on the cable at the parking brake pedal so it is slack. Next, remove the wheel and the plug on the face of the rotor. The adjuster can be accessed through the hole at the six o’clock position. Extend the adjuster until the wheel locks and then back off the adjustment until the wheel turns freely. Reattach the nuts for the cable at the pedal. Torque the locking nut to 48 inch/lbs.
