1985 Chevrolet G30 Chevy Van 8 Cyl 6.2L - Brakes
What is the difference between a JD7 or a JB8 brake system.
87k mileage, the power steering works well but the power brakes don't work. I just bought the vehicle. Some fan belt noise but not always, usually when it's cold, haven't looked to see which belt yet. there are many. Looking to replace the brake booster without the mastercylinder.

    JD7 is in the C25 and the JD8 is in the C30.............From what I'm told. Single vs Dual wheel. JB8 brakes use 13x3.5" drums, and 1.5" thick rotors w/Bendix calipers.
