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.
