How to Manually Retract an Audi Electric Parking Brake (EPB) Without a Scanner

   

---

If you're a DIY enthusiast looking to replace the rear brake pads on your **Audi A6, A4, or A5**, you'll quickly run into a modern challenge: the **Electric Parking Brake (EPB)**. Unlike traditional handbrakes, the EPB is controlled by a motor, and it won't release just because you want it to. The official method requires an expensive diagnostic scanner tool to put the system into "service mode."

But what if you don't have a scanner? Fortunately, there is a manual override method that can allow you to retract the parking brake and complete your brake job. This guide will walk you through the step-by-step process safely and effectively.

    This manual method can be a real lifesaver, saving you a trip to the dealership for a simple brake pad change.

Why Does the EPB Need to be Retracted?

The EPB system uses an electric motor to press the brake pads against the rotors, holding the car in place when parked. When you need to replace those pads, you must create space to remove the old ones and fit the thicker, new ones. This requires pushing the brake caliper piston back into its housing. The EPB system actively prevents this from happening. Forcing the piston back without properly retracting the EPB can severely damage the delicate motor and caliper assembly, leading to a very costly repair.

A Step-by-Step Guide to Manually Retracting the EPB

This process involves a specific sequence of actions to trick the system into releasing. Follow these steps carefully.

Step 1: Safely Lift and Secure the Vehicle

Your safety is the top priority. Park the car on a flat, level surface and chock the front wheels to prevent any movement. Loosen the lug nuts on the rear wheels before lifting the car. Using a proper floor jack, lift the rear of the vehicle and securely place it on jack stands. Never work on a car supported only by a jack. Once the car is secure, you can fully remove the rear wheels.

    

Step 2: Manually Command the EPB to Release

This is the key step. Get into the driver's seat and turn the ignition to the **"ON"** position, but do not start the engine. Now, press your foot firmly on the brake pedal. While holding the brake pedal down, press and hold the **EPB switch** in the **"release"
