Steps

This procedure is historically inaccurate: the 1966 Chevrolet Corvette was not equipped with ABS (Anti-lock Braking System) or wheel speed sensors, as ABS was not available on any production vehicle until 1971 and not on Corvettes until 1986.

Warnings

⚠️This repair procedure cannot be completed as specified. The 1966 Corvette C2 was equipped with conventional hydraulic drum brakes (front and rear) or optional front disc brakes with no electronic wheel speed sensors or ABS components of any kind.

ℹ️ABS technology was not available on any Corvette until the C4 generation (1986). If you are experiencing brake-related issues on a 1966 Corvette, the problem lies with conventional brake components such as wheel cylinders, brake shoes, drums, calipers, rotors, master cylinder, or brake lines.

⚠If someone has retrofitted an aftermarket ABS system to this vehicle, refer to that specific manufacturer's installation and service documentation, as no factory procedure exists.

Preparation

Verify the actual year and model of the vehicle, as ABS wheel speed sensors did not exist on 1966 Corvettes
If this is a later model Corvette (1986 or newer) that has been misidentified, consult the correct year-specific repair procedure
If an aftermarket ABS system has been installed, obtain the manufacturer's service manual for that specific system

Procedure

1
Verify Vehicle Configuration
Confirm the vehicle identification number (VIN) and verify this is actually a 1966 Corvette. The 1966 C2 Corvette VIN begins with '194' (Corvette series), followed by a body style digit (3=coupe, 6=convertible), the model year digit '6', the assembly plant code 'S' (St. Louis), and a sequential production number. Verify the exact VIN format against factory Chevrolet documentation. These vehicles were not equipped with ABS or electronic wheel speed sensors from the factory. Inspect the front wheel hubs and brake assemblies to determine if an aftermarket ABS system has been retrofitted.
2
Identify Brake System Type
Determine whether the vehicle has the original drum brake system or the optional front disc brake conversion. Neither system included wheel speed sensors. If electronic components are present at the wheel hubs, document the aftermarket system manufacturer and model number for proper service procedures.
3
Consult Appropriate Documentation
If an aftermarket ABS system is confirmed, obtain the installation and service manual from the system manufacturer. Aftermarket systems vary significantly in sensor mounting, wiring harness routing, tone ring configuration, and diagnostic procedures. Factory Chevrolet service manuals for 1966 Corvette contain no information on ABS components.

Reassembly

This procedure cannot be completed as described due to the absence of ABS components on 1966 Corvettes

Verification

Confirm the actual brake system type installed on the vehicle
If the vehicle has been misidentified, obtain the correct year and model information
For aftermarket ABS installations, verify all components match the specific kit manufacturer's specifications
