    my booster was so full of oil and hissing that I imagined it getting on the cat and causing the smoke

    I was having doubts about performance ever since I picked up my vehicle from the used card dealer …. I knew it had a mushy brake peddle and when bleed it only lasted a short time before becoming mushy again the last time out I drove surprisingly well to wallgreens but when driving back the peddle became hard as a rock and I didn't have any brakes when I got home there was hardly a smidge of oil in the reservoir and I heard vacuum hissing sounds coming from the brake booster
