In the realm of vehicle maintenance, brake issues often loom as a daunting and perplexing challenge for drivers. One such predicament that Subaru owners may encounter is the dreaded “Brake Maintenance Mode.” This mode activates when the vehicle’s computer detects a potential problem with the braking system, prompting the driver to seek immediate attention. While this feature serves as a vital safety measure, it can also be frustrating when it triggers unnecessarily or without clear explanation.
Understanding Brake Maintenance Mode in Subarus
Brake Maintenance Mode is a proactive measure implemented by Subaru to safeguard the integrity of the braking system. When the mode is activated, the vehicle’s computer limits brake performance to prevent potentially dangerous situations. This can result in reduced braking power, increased pedal travel, and a warning message displayed on the dashboard.
Common Causes of Brake Maintenance Mode Activation
– Faulty brake sensors
– Low brake fluid
– Air in the brake lines
– Faulty brake master cylinder
– Worn or damaged brake pads or rotors
It is important to note that Brake Maintenance Mode is not a diagnostic tool and may activate even if the issue is not severe. Regular inspections and diagnostics by a qualified mechanic are recommended to identify the underlying cause and resolve the problem promptly.
## How to Get Subaru Out of Brake Maintenance Mode
If your Subaru enters Brake Maintenance Mode, you’ll experience reduced speed and power, making it crucial to address the issue promptly. This mode activates when the vehicle detects a potential problem with the braking system.
### Understanding Brake Maintenance Mode
Subaru’s Brake Maintenance Mode primarily occurs due to two scenarios:
– **Faulty wheel speed sensor:** The sensor sends signals to the computer, indicating the speed of each wheel. A malfunctioning sensor can lead to inaccurate readings, triggering the mode.
– **Low brake fluid:** Adequate brake fluid is essential for optimal hydraulic pressure and lubrication. Low levels can trigger the mode as the system may not function efficiently. (See Also: How Much To Replace Brake Pads On Mercedes)
### Identifying Brake Maintenance Mode
Symptoms indicating Brake Maintenance Mode include:
– Reduced engine power and speed
– Illuminated brake warning light on the dashboard
– Anti-lock braking system (ABS) light illumination
– Reduced responsiveness and stability control functionality
### Steps to Get Out of Brake Maintenance Mode
**1. Check Brake Fluid Level**
– Locate the brake fluid reservoir under the hood.
– Use a dipstick to check the fluid level.
– If the level is low, add the recommended brake fluid.
– Consult your owner’s manual for the recommended fluid type.
**2. Inspect Wheel Speed Sensors**
– Locate the wheel speed sensors, usually mounted near each wheel hub.
– Check for damage, loose connections, or faulty sensors.
– Consult your owner’s manual for sensor location and replacement instructions. (See Also: Should I Change Rotors When Changing Brake Pads)
**3. Consult a Mechanic**
If the issue persists after checking the brake fluid and sensors, it’s recommended to consult a qualified mechanic. They can diagnose the problem, perform necessary repairs, and reset the mode.
**4. Resetting the Mode**
After addressing the underlying issue, follow these steps to reset the Brake Maintenance Mode:**
– Start the engine.
– Press and hold the **brake** and **accelerator** pedals simultaneously for approximately 10 seconds.
– The brake warning light should extinguish after a successful reset.
### Key Points
– Brake Maintenance Mode limits speed and power to protect the vehicle.
– Common causes include faulty wheel speed sensors and low brake fluid.
– Check the brake fluid level and inspect wheel speed sensors as initial steps.
– Consult a mechanic for diagnosis and repairs if necessary.
– Reset the mode by holding the brake and accelerator pedals simultaneously.

How do I identify if my Subaru is in Brake Maintenance Mode?
Your Subaru will display a warning light on the dashboard and may also limit your speed if it detects an issue with the braking system. Additionally, the brake pedal may feel stiffer or pulsate.
What are the possible causes of Brake Maintenance Mode activation?
Common causes include low brake fluid, faulty sensors, worn brake pads, or even contaminated brake fluid.
How do I reset the Brake Maintenance Mode?
Turn the ignition on without starting the engine. Press and hold the brake pedal for approximately 10 seconds. The warning light should disappear once the mode is reset.
What should I do if the Brake Maintenance Mode persists?
If the problem persists after resetting the mode, schedule an appointment with a qualified Subaru mechanic for a thorough inspection and diagnosis.
How can I prevent Brake Maintenance Mode from activating in the future?
Regularly check and top up the brake fluid, replace worn brake pads and sensors, and avoid driving through deep puddles or muddy conditions.
