The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup).

Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). For the fourth-generation (colloquially also known as OBS trucks), Chevrolet kept using the C/K designation while GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code).

For South America, the model line was manufactured by General Motors de Argentina from 1960 to 1978, Sevel Argentina from 1986 to 1991, and General Motors Brazil, who produced versions of the model line for Brazil, Argentina, and Chile from 1964 to 2001.

As GM entered the 1990s, the company revised its truck ranges, replacing the medium-duty C/K trucks with the Chevrolet Kodiak/GMC TopKick for 1990. For 1999, GM replaced the fourth-generation C/K pickup trucks with an all-new model line; in line with GMC, Chevrolet dropped the C/K nameplate (in favor of a singular Chevrolet Silverado nameplate). Initially marketed with its successor, the final C/K pickup trucks were produced for the 2000 model year. From 2001 to 2002, the final vehicles of the C/K model line were medium-duty chassis cab trucks.

Common 1977 Chevrolet C30 problems

The 1977 Chevrolet C30 is a classic truck with a few common problems that have been reported by owners. These issues include:

Gas Tank Placement: The gas tank on the 1977 Chevrolet C30 is mounted outside the frame rail, which can be a problem if the truck is involved in a collision. This placement could increase the risk of a fire or fuel leak in the event of an accident.

Brake System Failure: Another common problem with the 1977 Chevrolet C30 is brake system failure. One owner reported that when the brake primary pump is out, the brake pedal goes to the floor and there are no brakes. This problem could be caused by a faulty brake master cylinder or a leak in the brake lines.

Engine Oil Loss: The 1977 Chevrolet C30 has been recalled due to a problem with inadequate sealing and loss of engine oil, which could potentially result in a fire. This problem is caused by a defect in the fuel system and is a serious safety concern.

Power Steering and Brake System: The 1977 Chevrolet C30 is known to have issues with the power steering and brake system. The power steering pump can seize up, causing the belt to squeal and the pedal to go to the floor. Additionally, when the brake primary pump is out, the brake pedal goes to the floor and there are no brakes. This is due to a lack of proper maintenance and can be a serious safety concern.
