1973–1977 Chevrolet Chevelle, Malibu, Impala & Caprice NOS Park Brake Switch #1241639

Available for sale is a genuine General Motors New Old Stock (NOS) Park Brake (Parking Brake) Switch, GM part number 1241639, designed for select 1973–1977 Chevrolet passenger car applications including Chevelle, Malibu, Impala, and Caprice models. This original GM service replacement component is a rare and valuable find for restorers seeking factory-correct brake and safety system electrical parts.

The parking brake switch is an important safety-related electrical component that activates the warning light on the dashboard when the parking brake is engaged. This system helps alert the driver when the parking brake is applied, ensuring proper operation and preventing accidental driving with the brake engaged.

The Chevrolet mid-1970s lineup, including the Chevelle, Malibu, Impala, and Caprice, represents a major era in GM full-size and intermediate vehicle production. These models were widely used for personal transportation, fleet service, and law enforcement applications. Today, they remain popular among collectors and restoration enthusiasts due to their comfort, durability, and classic GM design.

Over time, original parking brake switches can fail due to wear, corrosion, electrical contact failure, or mechanical fatigue. A faulty switch may result in a non-functioning brake warning light, which reduces driver awareness of parking brake engagement and compromises safety system functionality.

This component is a true New Old Stock (NOS) GM service replacement part, meaning it was manufactured during the original production era and has never been installed on a vehicle. It retains factory specifications, original materials, and GM engineering standards intended for proper electrical performance and fitment.

Unlike modern reproduction parts, NOS GM electrical components provide authentic construction and correct terminal design, ensuring proper compatibility with original wiring harnesses and dashboard systems. This is especially important in vintage vehicles where electrical accuracy and reliability are critical.

For restorers, maintaining originality in safety-related systems such as the parking brake indicator is essential for both authenticity and proper vehicle operation. Whether restoring a Chevelle SS, a Malibu cruiser, or a full-size Impala or Caprice, using correct GM components helps preserve factory functionality.

As original GM electrical service parts become increasingly difficult to locate, NOS switches like this have become highly sought after by collectors and professional restorers aiming for factory-correct or concours-quality restorations.
