LEFT: This is what our project ‘86 brakes looked like before we started. The first thing you will want to do is jack the front of your Corvette off the ground and make sure you support the car on jack stands. Remove both wheels.

BELOW LEFT: Using a 13mm wrench, remove the caliper line bolt. This is a special bolt that is not supplied in the kit, so make sure you do not misplace it. If you are going to be replacing your brake line (a good idea), then you can go ahead and loosen it from the steel line where it is attached to the car and discard it.

We are going to be replacing our stock 12-inch single-piston brakes with a set of 13-inch dual piston Grand Sport brakes that came on the ‘96 Grand Sport Corvettes. Zip Products provided a complete big brake package with the Grand Sport calipers and the 13-inch Gas Vane rotors. Keep in mind that Zip offers both styles of kits, either 1985-87 or 1988-96.
