What Happens If You Don’t Put Brakes in Service Mode? Avoid These Costly Mistakes
Brakes have gotten smarter and more complex as vehicles have aged. You may have likely read about it in connection with just recently replacing a brake pad, or if you intend to do it on your own. But what does it mean? But more importantly, what if you do not take this critical step?
Drivers and even some DIY enthusiasts skip this process, as they think it is not required. The truth is, if you forget to activate brake service mode, it can cause catastrophic damage, you could face an unsafe vehicle, and an eye-watering repair bill.
In this article, we’ll walk you through what brake service mode is, why it matters, and the consequences of ignoring it, especially for vehicles with electric parking brakes.
What Is Brake Service Mode?
Brake service mode is a specific function available on many new vehicles, especially those with an electric parking brake (EPB). The system momentarily disengages or disables the electronic parking brake system to safely replace brake pads, machine rotors, or work on calipers.
Back in the day, with cars with unlockable mechanical parking brakes, you just had to pull a lever or disconnect a cable. However, in modern cars, brake calipers are operated by electric motors. Without disabling these motors first, they may remain engaged, or worse, activate during the repair process.
When Do You Need Brake Service Mode?
- Replacing brake pads
- Changing brake rotors
- Servicing calipers
- Inspecting electric parking brake systems
Whether you’re a technician or a DIYer, service mode is not optional in these situations. It’s a safety step that prevents both damage and injury.
What Can Go Wrong If You Skip Brake Service Mode?
Now, let’s break down the costly consequences of ignoring this essential process.
1. Damaged Electric Parking Brake Motors
Electric parking brake motors are not designed to work against tools. If you try to push the piston back in without disabling the EPB, you’ll strain or even burn out the motor. These motors are expensive to replace — often running several hundred dollars or more — and damage may not be covered by warranty if caused by improper servicing.
2. Ruined Brake Calipers
Without entering service mode, the brake caliper pistons remain pressurized. Forcing them back can break the piston, seal, or housing. A new caliper, along with labor, can easily cost $300–$500 or more, depending on your vehicle.
3. Brake Warning Lights and Errors
Modern vehicles have features that will register when something is wrong with the operation of your brake system. You must use service mode, or the ABS, EPB, or Brake System Warning Lights will come on and require diagnostic resets from the dealership or repair shop.
4. Incomplete Repairs
If the pots cannot retract, the new brake pads will not fully seat, which means they will not fully make contact with the rotors. This can cause compromised braking efficiency, uneven brake pad wear, noise, and loss of stability.
5. Voided Warranty or Insurance Issues
If you damage brake system components during DIY maintenance, especially by skipping service mode, many warranties will refuse coverage. Also, in case of a brake-related accident, insurance claims can be denied if it’s proven that the vehicle was improperly serviced.
How to Put a Vehicle into Brake Service Mode
The process varies depending on your car’s make and model, but it generally involves the following steps:
- Turn the ignition to the ON position (without starting the engine).
- Use a scan tool or onboard menu (via infotainment screen or dash controls).
- Navigate to ‘Brake Pad Replacement’ or ‘Maintenance Mode’.
- Confirm or activate the mode.
Some vehicles may require a diagnostic tool like an OBD-II scanner with service mode support. Without this, it may be impossible to retract the calipers electronically.
How Often Should You Get Brake Service?
Even with service mode aside, it’s worth remembering that regular brake inspections are crucial. Here are some general guidelines:
- Inspect brake pads every 15,000–20,000 km.
- Replace pads every 30,000–70,000 km based on driving habits.
- Replace brake fluid every 2–3 years.
- Full system checks annually, especially before winter.
If your car has EPB, ensure every service technician you visit is familiar with service mode and uses it properly.
