My 87 300TDT pulls 57cm (22") of vacuum, enough to 'tug' your finger without hurting. I measured it tonight to track down my brake pedal travel. It goes to the floor, but I still have 'standard' brakes. No fluid loss and the brakes, upt to a week ago, could be pumped two or three times to firm up, only after run some miles. Now no apparent boost. Gonna try a new booster.
