Brake Shoes and the 2021 Subaru Outback: What You Need to Know

When it comes to the 2021 Subaru Outback, it's important to note that this model does not use brake shoes. Instead, the Outback relies on disc brakes all around, which means it has brake pads rather than brake shoes. So, what's the deal with brake shoes and why aren't they used in this vehicle? Let's dive into those questions and explain the role of brake shoes in cars more broadly, and why the 2021 Subaru Outback takes a different approach for its braking system.

Brake shoes are a key component of drum brake systems, which were once common in older vehicles and are still used in many cars, particularly on the rear wheels of entry-level or smaller cars. Brake shoes are curved pieces of metal with friction material bonded to the outside surface. These shoes press outward against the inside of a rotating drum attached to the wheel, creating the friction needed to slow or stop the vehicle.

The 2021 Subaru Outback, however, uses disc brakes on both front and rear wheels. Disc brakes use brake pads that squeeze against a rotor (a flat disc attached to the wheel hub) to stop the vehicle. This system is generally regarded as having better performance, especially under heavy braking and wet conditions, which is why manufacturers like Subaru have moved towards using disc brakes all round on vehicles like the Outback. The Outback's all-wheel drive system and adventure-ready nature also benefit from disc brakes' superior heat dissipation and consistent braking power.

So, the absence of brake shoes on the 2021 Subaru Outback is simply down to its choice of braking system. The disc brake setup offers several advantages over drum brakes, including improved stopping power, easier maintenance, and better feedback to the driver. It also reduces the risk of brake fade during prolonged use - something that's particularly useful if you're often driving in hilly or rugged terrain.

Even though brake shoes aren't part of your 2021 Outback's braking system, understanding them is useful for anyone who may have driven older cars or is curious about how different brake types work.

Brake shoes serve to create friction inside the brake drum to slow your car down, much like brake pads in disc brakes. As the driver presses the brake pedal, hydraulic pressure forces the shoes outward, gripping the drum from the inside. Because the friction surface of brake shoes wears away over time, they require regular inspection and timely replacement to keep braking effective and safe.

If brake shoes wear down too much without being replaced, the metal backing can rub on the drum, causing damage and reducing stopping power. It can also create noises like squealing or grinding which are a dead giveaway that the brakes need servicing. Maintaining brake shoes involves checking their thickness, ensuring the drum is not scored or warped, and replacing both shoes at the same time to ensure even stopping performance.

For rear drum brakes fitted with brake shoes, it's also essential to check that the return springs and other components are in good shape and properly adjusted. Poor adjustment can lead to a spongy brake pedal or uneven wear, impacting braking efficiency and safety on the road.

While the 2021 Subaru Outback does not use brake shoes, it does rely on brake pads and rotors for stopping power, which also require care and maintenance to function at their best. Regular brake service includes checking brake pad thickness, rotor condition, and making sure brake fluid is at the correct level and quality. The intervals for brake servicing can vary depending on driving style and conditions but inspecting your brakes at least every 15,000 to 20,000 kilometres is a good rule of thumb.

In summary, brake shoes are not found on the 2021 Subaru Outback because the vehicle features an all-disc brake system that provides better performance and reliability. While brake shoes remain a crucial part of drum brake systems on many other vehicles, Outback owners will focus on brake pads and rotors to keep their car stopping safely. Knowing the difference helps owners appreciate their specific brake setup and encourages keeping up with proper maintenance for optimal vehicle safety and performance.
