Yes, both brake pads of your vehicle must be replaced at the same time. For your brake system to work properly, you need to change both brakes at once. The reason is simple – both brakes work together to stop the car. Now, your brake system won’t be smooth and easy if one of the brake pads is old, while the other one has been replaced recently. This can cause uneven braking, which increases the risk of collisions. Another important reason why you must replace both brakes at once is that your vehicle must stop and get stable once you have pushed the brake pedal. With the old and a new brake, your car might stop instantly, but it is highly likely to swerve.
