1960 Studebaker 5E13D Brake Light Switch: Function and Replacement
Understanding the unique hydraulic brake light switch in your classic Studebaker truck.
- The 1960 Studebaker 5E13D uses a hydraulic pressure switch for the brake lights, not a mechanical one at the pedal.
- Symptoms of failure include brake lights not working, staying on, or working intermittently.
- The Standard Ignition aftermarket switch is a reliable, direct-fit replacement.
- Replacement is a feasible DIY job, but requires bleeding the brakes afterward for safety.
Understanding Your Studebaker's Brake Light Switch
The brake light switch on a 1960 Studebaker 5E13D is a simple but critical safety component. Unlike modern cars that use a mechanical switch activated by the brake pedal itself, your classic truck uses a hydraulic switch that reacts to brake fluid pressure. This design was common for the era. The switch is located outside the cab, typically screwed into the master cylinder or a T-fitting in the brake lines on the frame. When you step on the brakes, the force creates hydraulic pressure that activates the switch, turning on the brake lights.
Symptoms of a Failing Brake Light Switch
Before suspecting the switch, it's always a good idea to check the simple things first: make sure the brake light bulbs are good and check the fuse. If those are fine, the switch is a likely culprit. Common symptoms include:
- Brake Lights Do Not Work: The most common and dangerous symptom. The switch has likely failed internally and is not completing the electrical circuit.
- Brake Lights Stay On: The switch can fail in the 'on' position, which will keep the brake lights illuminated even when you're not braking. This can drain your battery and confuse other drivers.
- Intermittent or Flickering Lights: A worn switch might work only some of the time or cause the lights to flicker.
- Lights Only Work With Hard Braking: A failing switch may require more hydraulic pressure than normal to activate, meaning your lights won't come on during gentle stops.
Choosing the Right Aftermarket Brake Light Switch
For a vehicle of this age, new original equipment (OEM) parts from Studebaker are not available. The only practical option is a new aftermarket part. The Standard Ignition brand is a long-standing and trusted manufacturer of replacement parts for classic vehicles. Their switches are designed to be direct replacements for the original part.
Pro Tip: Check Your Brake Fluid
Some owners of classic cars have noted that modern DOT 5 silicone brake fluid can sometimes cause premature failure in reproduction hydraulic switches. While the Standard Ignition switch is a reliable replacement, if you are using silicone fluid and experience repeated failures, some owners opt to fabricate a bracket and install a more modern mechanical switch at the brake pedal.
Brake Light Switch Replacement Cost
Replacing the brake light switch is an affordable repair. The main cost is the part itself, with labor being minimal for a professional mechanic.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Switch (Standard Ignition) | $15 - $20 |
| Shop Labor | $50 - $100 |
| Total Estimated Cost | $65 - $120 |
Note: Costs are estimates and may vary based on your location and mechanic's rates. The job requires bleeding the brakes after switch installation, which is included in the labor estimate.
Frequently Asked Questions
Where is the brake light switch located on my 1960 Studebaker 5E13D?
The brake light switch is not inside the cab by the pedal. It is a hydraulic switch located under the hood, screwed into the master cylinder, or on the frame rail where the brake lines connect. It will have two electrical wires attached to it.
Is replacing the brake light switch a DIY job?
Yes, for a mechanic with some experience. The switch itself is easy to unscrew and replace. However, because it is part of the hydraulic brake system, you will introduce air into the lines when you remove it. You MUST bleed the brakes properly after installation to ensure your brakes work safely. If you are not comfortable bleeding brakes, this job is best left to a professional.
How can I test my old brake light switch?
A simple way to test if the switch is the problem is to first check your bulbs and fuse. If they are good, locate the switch and unplug the two wires connected to it. Use a small jumper wire to connect the two wire terminals together. If the brake lights turn on, the switch is bad and needs to be replaced. If they do not light up, you have a problem elsewhere in the wiring.
Are there any recalls for the brake light switch on my Studebaker?
No, there are no active recalls or specific Technical Service Bulletins (TSBs) found for the brake light switch on a 1960 Studebaker 5E13D. Safety recalls for vehicles of this era are extremely rare and the NHTSA database does not contain specific data for this component.
