Brake Light Switch Guide for the 1961 Studebaker 6E11 Truck
Ensure your classic Studebaker's brake lights work reliably with the right replacement switch.
- The 1961 Studebaker 6E11 uses a hydraulic pressure switch for its brake lights, not a mechanical one at the pedal.
- Failure symptoms are critical and straightforward: lights don't work, stay on, or work intermittently.
- A new aftermarket switch from a reputable brand like Standard Ignition is the most practical and reliable replacement option.
- Replacement is a simple DIY task, but you must bleed the brakes afterward to ensure the system is safe.
Symptoms of a Failing Brake Light Switch
On a straightforward truck like a vintage Studebaker, the signs of a bad brake light switch are usually clear. Before you assume the switch is the problem, always check your brake light bulbs and the fuse first. These are common failure points and are easy to check.
- No Brake Lights: This is the most common and dangerous symptom. If you have confirmed the bulbs and fuse are good, the switch is the most likely culprit. An internal failure prevents the switch from completing the electrical circuit.
- Brake Lights Stay On: If the switch fails in the 'on' position, it will constantly send power to the brake lights. This can drain your battery when the truck is parked and confuse other drivers.
- Intermittent or Flickering Lights: A worn-out switch might cause the lights to flicker when you press the pedal or only work when you brake hard. This indicates an unreliable internal connection that will likely fail completely soon.
Choosing the Right Aftermarket Switch
Finding a New Old Stock (NOS) OEM brake light switch for a 1961 Studebaker is nearly impossible. For this reason, a new aftermarket part is the standard and most reliable choice for keeping your classic truck on the road.
Brand Spotlight: Standard Ignition
Standard Ignition (also known as Standard Motor Products or SMP) is a well-regarded brand in the aftermarket, known for producing quality replacement parts for a wide range of vehicles, including classics. Their switches are manufactured to meet or exceed original specifications and are a trusted choice among professional technicians. For a simple but crucial part like a hydraulic brake light switch, a quality aftermarket replacement from a brand like Standard Ignition is a dependable and cost-effective solution.
A Note on Brake Fluid
Some owners of classic cars report that modern silicone brake fluid can cause premature failure in reproduction hydraulic brake light switches. The switch available for your truck is noted as not being for use with silicone brake fluid. Be sure to use the correct type of brake fluid as recommended for your vehicle's system.
Replacement Cost
Replacing the brake light switch is an affordable repair. The part itself is inexpensive, and if you have it done by a professional, labor should be minimal. The main cost factor is the need to bleed the brakes after installation.
| Part Type | Price Range |
|---|---|
| New Aftermarket (Standard Ignition) | $15 - $22 |
| New OEM (NOS) | Not readily available |
| Shop Labor | $80 - $150 |
Frequently Asked Questions (FAQ)
Where is the brake light switch located on my 1961 Studebaker 6E11?
The brake light switch is not inside the cab by the pedal. It is a hydraulic pressure switch located in the engine bay or on the frame rail. Look for a small sensor with two wires screwed into the master cylinder or a brake line junction block.
Is this a difficult part to replace myself?
For a DIY mechanic, this is a relatively easy job. It involves unplugging the wires, unscrewing the old switch, and quickly screwing in the new one to minimize brake fluid loss. However, you must bleed the brakes after replacement to remove any air that entered the system. This step is critical for safety.
How can I test my old brake light switch?
First, confirm your bulbs and fuse are good. Then, locate the switch and unplug the two wires. Use a small jumper wire to carefully 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, the problem is elsewhere in the wiring.
Are there any recalls for the brake light switch on my truck?
No, there are no recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the brake light switch on a 1961 Studebaker 6E11. This is normal for a vehicle of this age, as modern recall systems were not in place.
