I have a 2007 IS350 3.6L 6 cil. The power brake booster is slowly losing vacuum, I replaced the check valve and grommet with no luck. I am guessing the power brake booster has a leak and need replacement.
Is any way to remove and replace the power brake booster without removing the ABS actuator and pump assembly? I am trying to prevent doing extra work removing the lines and bleeding the system, plus I am not sure if I need to plug it to a computer for any type of calibration.
Any feedback will be appreciated.
