I put my foot on the brake and I hear a hissing noise. The brake pedals get really hard and it is difficult to stop. In addition, when I step on the brake pedal, the the engine revs a little bit higher. i need some advise- Thank you.
I saw this 1973 Z going for $45,000. What makes a 1973 z be worth this much money? http://cgi.ebay.com/ebaymotors/1973-Datsun-240z-Candy-Apple-Red-show-car_W0QQitemZ160164078438QQihZ006QQcategoryZ6187QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
