Choosing the Right Aftermarket Part for Your Brunn
For a rare, coach-built vehicle like a 1939 Lincoln Brunn, finding original "New Old Stock" (NOS) OEM parts is nearly impossible and often prohibitively expensive. Aftermarket parts are the most practical and often the only available solution for keeping these classics on the road.
Standard Ignition (Standard Motor Products): This is a well-established brand that has been producing automotive parts for decades. They are a known source for reliable components for vintage vehicles. For a part like a brake light switch, their product is designed to meet or exceed the original specifications and offers a dependable, affordable solution. Given the rarity of your vehicle, a quality aftermarket switch from a brand like Standard Ignition is an excellent choice.
Replacement Cost
The cost for a new aftermarket brake light switch is very reasonable. The main challenge with OEM parts is not the cost, but the sheer lack of availability.
| Part Type | Price Range |
|---|---|
| New OEM | Not Generally Available |
| New Aftermarket (Standard Ignition) | $15.52 - $15.52 |
| Used OEM | Varies Widely (based on rarity and condition) |
Frequently Asked Questions
Is the brake light switch on a 1939 Lincoln mechanical or hydraulic?
Vehicles from this era used both types. Some switches are mechanical and activated by the movement of the brake pedal arm. Others are hydraulic pressure switches that screw into the master cylinder or a brake line and are activated by the pressure of the brake fluid when the pedal is pressed. It is important to identify which type your vehicle has before ordering a replacement.
Can I replace a hydraulic switch with a mechanical one?
Yes, and it is a common modification on classic cars. Many owners of vintage vehicles choose to convert from a hydraulic pressure switch to a more reliable mechanical switch. This often solves problems with switches that fail due to modern brake fluids or require too much pedal pressure to activate.
Is replacing the brake light switch a difficult job?
Generally, no. For a person with basic mechanical skills, this is a straightforward task. A mechanical switch is typically mounted near the top of the brake pedal arm. A hydraulic switch is usually located on the master cylinder. The primary challenges may be reaching the switch's location or dealing with aged wiring.
Are there any recalls for the brake light switch on a 1939 Lincoln?
No recalls were found for the 1939 Lincoln Brunn concerning the brake light switch. The National Highway Traffic Safety Administration (NHTSA) database does not contain records for vehicles of this age. Searches for modern Lincoln recalls for similar issues are not relevant to your classic vehicle.
