2007 Toyota RAV4 Parts Questions & Experts Answers

• Q: How to service and repair the vacuum brake booster on 2007 Toyota RAV4?

  A: Service and repair operations on the vacuum brake booster require first removing the air cleaner case for both 2AZ-FE or 2GR-FE engines using proper removal methods. The immediate draining of brake fluid becomes essential because it damages paint until you disconnect the brake lines. The replacement sequence begins with removing both ABS and traction actuator assembly and the bracket followed by the brake master cylinder sub-assembly. Disconnect the vacuum hose and then remove the push rod pin by sliding off the clip followed by pulling the pin out from the push rod clevis. Separate the push rod clevis by loosening its lock nut before taking out the clevis component. To perform the next step remove the brake booster assembly through the process of nut detachment before extracting it while keeping the gasket intact. The brake booster gasket requires removal before inspecting the check valve assembly alongside its grommet. Start your installation process by putting the check valve grommet onto the booster before setting the check valve into its place in the grommet. Insert and secure the brake master cylinder push rod clevis followed by torquing the lock nut only temporarily. Fasten the brake booster assembly to the vehicle using the 4 nuts while torquing them to 12.7 Nm (130 kgf-cm, 9 ft. lbs.). Install the push rod pin into the clevis after covering it with lithium soap base glycol grease and then secure it with the clip. First adjust the push rod of the brake booster and then connect the vacuum hose to the check valve before reinstalling the brake master cylinder sub-assembly. The ABS and traction actuator assembly requires bracket mounting before linking brake lines while filling the reservoir with brake fluid followed by air bleeding from the master cylinder as well as the brake line and the ABS and traction actuator assembly. Examine and modify the brake pedal height and free play together with the reserve distance and reservoir fluid level before inspecting for brake fluid leaks. Repeat the installation process of the air cleaner case through proper procedures for each engine type.
