The Moss Motors MGB brake warning switch is a critical safety component that alerts you to potential issues within your braking system. A malfunctioning switch can be frustrating and potentially dangerous. This comprehensive guide dives deep into the intricacies of the Moss Motors MGB brake warning switch, offering troubleshooting tips, solutions, and expert advice to get your classic car back on the road safely.
Understanding the Moss Motors MGB Brake Warning Switch
The brake warning switch in your MGB serves a vital function: it illuminates a warning light on your dashboard when there’s a problem with your braking system, such as low brake fluid or unequal pressure between the front and rear brakes. Understanding how this small but crucial component works is the first step in diagnosing and resolving any issues. The switch is typically located under the dashboard, connected to the brake hydraulic system. When the pressure in the system changes, the switch activates, turning on the warning light. This simple mechanism can prevent serious braking problems.
A common issue is the switch activating when it shouldn’t, causing the warning light to stay on even when the brakes are functioning correctly. This can be due to a faulty switch, incorrect adjustment, or problems within the hydraulic system itself. Conversely, a failing switch might not activate when it should, leaving you unaware of potential brake issues.

Troubleshooting a Malfunctioning Moss Motors MGB Brake Warning Switch
Before you start tearing apart your dashboard, there are a few simple checks you can perform. Firstly, check your brake fluid level. Low brake fluid is a common culprit for triggering the warning light. If the fluid is low, top it off and see if the light goes out. If the light persists, check the brake lines for any leaks or damage.
Next, inspect the wiring connected to the switch. Look for loose connections, corrosion, or damaged wires. A multimeter can be used to test the switch itself for continuity. If the switch fails the continuity test, it’s likely the culprit and needs replacement.

“Checking the simple things first, like fluid levels and wiring, can often save you time and money,” advises Michael Stevenson, a classic car restoration specialist with over 20 years of experience. “Don’t jump to conclusions and replace parts unnecessarily.”
Replacing the Moss Motors MGB Brake Warning Switch
Replacing the switch is a relatively straightforward process. Disconnect the battery terminals first and foremost for safety. Locate the switch under the dashboard, typically attached to the brake pedal mechanism. Disconnect the wiring harness and remove the old switch. Install the new switch, ensuring it’s properly seated and connected. Reconnect the wiring harness and battery terminals. Once complete, test the brakes and ensure the warning light functions correctly.
