1960 Studebaker 5E13 Brake Light Switch Replacement Guide
Understanding the unique hydraulic brake light switch in your classic Studebaker truck.
- Your Studebaker uses a hydraulic pressure switch in the brake line, not a mechanical switch at the pedal.
- Aftermarket hydraulic switches have a high failure rate and are often not compatible with DOT 5 silicone brake fluid.
- Replacement requires bleeding the brakes, which is a critical safety step.
- For better reliability, consider converting to a modern mechanical switch mounted by the brake pedal.
Symptoms of a Failing Brake Light Switch
A faulty brake light switch on your Studebaker Champ is a major safety concern. The symptoms are usually easy to spot. Since this is a simple hydraulic switch, the signs of failure are direct and shouldn't be ignored.
- Brake Lights Do Not Turn On: This is the most common and dangerous symptom. The switch has failed completely and no longer completes the electrical circuit when you press the brakes.
- Brake Lights Are Stuck On: The switch can also fail in the 'on' position, causing the brake lights to stay illuminated even when you're not braking. This can drain your battery and confuse other drivers.
- Delayed or Intermittent Lights: The switch may require very hard pedal pressure to activate, meaning your lights don't come on during gentle stops. You might also notice them flickering as the switch begins to fail.
Known Issues with Aftermarket Hydraulic Switches
Owners of classic vehicles that use this type of hydraulic switch report a high failure rate for modern replacements, with some parts lasting less than a year. A primary cause for failure is incompatibility with modern brake fluids. Most aftermarket hydraulic switches are NOT designed for use with DOT 5 silicone brake fluid. Using silicone fluid can cause the new switch to fail very quickly. If you have upgraded your brake system to DOT 5 fluid, a direct replacement hydraulic switch is not a reliable option.
Choosing the Right Aftermarket Part
For the 1960 Studebaker 5E13, your primary aftermarket option is a direct replacement hydraulic switch from a brand like Standard Ignition. There are no different quality tiers; the key is understanding the limitations of this part design.
Option 1: Direct Replacement (Standard Ignition SLS27)
Standard Motor Products (SMP) is a well-known aftermarket manufacturer that has been around since 1919. Their replacement switch, the SLS27, is designed to match the original's function. It is the most straightforward replacement if your truck still uses conventional DOT 3 or DOT 4 brake fluid. Reviews are generally adequate, with users confirming it works upon installation. However, be aware of the potential for premature failure that is common with this type of switch.
Option 2: Upgrade to a Mechanical Switch
For long-term reliability, many Studebaker owners convert to a modern mechanical brake light switch. This involves fabricating a small bracket to mount a simple plunger-style switch near the brake pedal arm. When you press the pedal, the switch is activated instantly. This popular modification provides more reliable and immediate brake light activation, is compatible with all brake fluid types, and eliminates a potential hydraulic leak point from your brake system.
Estimated Replacement Costs
The cost for a new aftermarket hydraulic switch is low, but labor can be higher than for a modern car because it requires bleeding the brakes.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Switch (Standard Ignition) | $15 - $20 |
| Shop Labor (includes bleeding brakes) | $100 - $200 |
| Total Professional Replacement | $115 - $220 |
Frequently Asked Questions (FAQ)
Where is the brake light switch located on my 1960 Studebaker truck?
The brake light switch is not inside the cab. Look for a small, brass-colored switch with two wire terminals screwed into the master cylinder or a junction block in the brake lines, located in the engine bay or along the frame rail.
Can I replace the brake light switch myself?
Yes, if you are comfortable working on hydraulic brake systems. The job requires unscrewing the old switch, installing the new one, and then bleeding the brake system to remove any air that entered the lines. This last step is critical for safety. If you are not familiar with bleeding brakes, this job is best left to a professional mechanic.
Why did my new brake light switch fail so quickly?
The most common reason for rapid failure of a new hydraulic switch is using it with DOT 5 silicone brake fluid. These switches are generally not compatible with silicone fluid. Another reason is the generally inconsistent quality and high failure rate reported for this type of reproduction part.
Are there any recalls for the brake light switch on my Studebaker?
No, there are no NHTSA recalls or Technical Service Bulletins (TSBs) on record for the brake light switch on a 1960 Studebaker 5E13. This is expected for a vehicle of this age.
