I got my brakes inspected today and after the initial test drive they put down on paper: Brake pedal sits VERY high and is VERY hard.Booster is still working.Has steering vibration at ALL times.Engine has a BIG vibration [big cam?] Dead miss? I have recently drove my car about 3k miles in the past two weeks and the other night I noticed a funny "burnt" kind of smell after I came home. The next day I did notice a "rougher" idle than normal and it's still the same, but the smell I had seems to be gone. As for the steering vibration, I have a Z51 and they were driving rough roads. '86 Z51 107k miles.
