Hello everyone. I have trolled routinely with great insights from IH8MUD. I thank you very much and that was long overdue. I first Yota'd purchasing a coworkers 96 4Runner unlimited. 200K of loved performance for a project which began and ended with and FJ set of wheels and tires that thing is flat awesome. I quickly moved to a 95 FJ with half the mileage and none of the appreciation. Originally owned by a foreign (no disrespect just insight into the issues) GP who likely never realized he'd need to wash road salt out from underneath of it. Kentucky is unpredictable on the need for that but it shows overall the needless neglect for such a machine.
I've replaced all of the front brakes assembly with no improvement to this issue. Discs, rotors, brake lines. I would like some insight please before I purchase anything else needlessly.
Front brakes begin to grab, vibrating the front end/ steering after about 10 miles of driving. Like they're loosing the vacuum that holds the discs off their rotors. When I go to brake terrible vibration from the front. Starts out slow and increases to a violent level sometimes.
But if I'm able to tap them occasional going down the road, sometimes difficult to do in going to work traffic the vibration will lighten up sometimes even cease. Actual braking (at least when this clears up) is perfect.
Could this be the vacuum booster or the master cylinder? If not does anyone know of a common place it could be leaking off? Does anyone know the vacuum spec that comes off of the intake to the vacuum booster. Didn't see it in the FSM but I'm sure it will be in there somewhere. Specs no doubt.
