Whiskers haute in die Tasten:
I had the same encounter: My first car was a '72 VW Type 2 Transporter (like VW Bus but with less cosy interior) The car had drum brakes on all wheels and no power brake assistance. During that time my parents had this brand new Citroen GS Break special with all- wheel HP operated disc brakes. It was more than once that I produced some blue smoke with that.
