1981 C3 Corvette

From 1965 the Corvette used four-wheel disc brakes with four-piston calipers. Over time, moisture in the brake fluid pits the caliper bores and the seals start leaking. A common fix is rebuilding the calipers with stainless steel sleeves, which resist pitting.

C1 through C3 Corvettes have tight engine bays and old cooling designs. Many run hot in traffic or on warm days, especially after decades of mineral build-up, missing seals, or mismatched parts. Most cases come down to airflow, the radiator, the fan or the ignition timing.

Under the fiberglass body, C2 and C3 Corvettes have a steel inner structure often called the "birdcage." It surrounds the cabin and windshield. Water leaks from windshield and roof seals can rust it, especially at the windshield pillars and the lower windshield frame. Repairs can be extensive because the body may need to come off.

C3 headlights (and the wiper door on early cars) open and close using engine vacuum. Cracked hoses, leaking actuators, a failing control valve or a leaking reservoir make the doors slow, stuck or droop open over time. It's a system of many small parts, so leaks are common.

Seals and hardware to rebuild the four-piston calipers used on 1965–82 Corvettes. Many owners choose sleeved calipers to prevent future leaks.

A consumer-grade ceramic coating kit for paint, wheels and trim. Paint must be fully cleaned and decontaminated first for best results.

An automatic charger and maintainer with an AGM mode and a quick-connect pigtail. Safe to leave connected for long-term storage.

A replacement vacuum actuator for C3 pop-up headlight doors. Replace the hoses at the same time for best results.
