Brake Wheel Cylinders on the 2017 Subaru Exiga: What You Need to Know

The 2017 Subaru Exiga is a versatile and practical vehicle, popular for its spacious interior and reliable performance. When it comes to its braking system, it's important to understand whether certain components like brake wheel cylinders are part of the setup. After checking technical references and repair manuals, it turns out that the 2017 Subaru Exiga does not use brake wheel cylinders in its braking system.

So why is this the case? Brake wheel cylinders are typically found in drum brake systems, where they play a crucial role in pushing the brake shoes against the drum to create friction and slow the vehicle down. However, the 2017 Subaru Exiga comes equipped with disc brakes on all four wheels, which changes the components involved in the braking mechanism.

Disc brakes operate using a different set of parts called calipers and pistons. These calipers squeeze the brake pads against a spinning disc (or rotor) to generate stopping power. Because the Exiga uses disc brakes, the traditional brake wheel cylinder found in drum brake systems is not necessary or present. Instead, the hydraulic pressure generated when pressing the brake pedal activates the pistons inside the calipers, making the brake wheel cylinder obsolete in this setup.

It's worth noting that drum brakes and their brake wheel cylinders are still common on older vehicles or sometimes on the rear wheels of certain budget models. However, as braking technology has advanced, manufacturers like Subaru have moved toward all-round disc brakes for improved stopping power, better heat dissipation, and overall enhanced safety. That is why the Exiga's brake system leans on caliper pistons rather than brake wheel cylinders.

That said, understanding brake wheel cylinders is still useful knowledge for many drivers, especially when dealing with vehicles that have drum brakes. Brake wheel cylinders are hydraulic components located inside the drum brake assembly. When the driver presses the brake pedal, brake fluid is forced through the brake lines into the wheel cylinders. This hydraulic pressure pushes the pistons inside the cylinder outward, forcing the brake shoes to press against the drum. This friction generates the braking force needed to slow or stop the vehicle.

Brake wheel cylinders are typically made of metal and have rubber seals that keep the brake fluid from leaking. Like all brake components, they are subject to wear and tear, especially the rubber seals which can dry out, crack, or result in brake fluid leaks over time.

For vehicles that do use brake wheel cylinders, regular maintenance and inspections are crucial. Leaking or failing wheel cylinders can cause a drop in brake fluid pressure, leading to a soft brake pedal or reduced braking effectiveness. This is a safety concern and means the vehicle needs immediate attention. Professionals recommend checking for signs such as brake fluid leaks near the wheels, uneven brake shoe wear, or a spongy feeling under the brake pedal. If any of these are noticed, the brake wheel cylinders should be inspected and replaced if necessary.

Replacing brake wheel cylinders involves a few important steps. First, the mechanic will remove the wheel and brake drum to access the cylinder. The brake lines connected to the cylinder will be carefully disconnected to avoid damage or fluid spillage. Old cylinders are removed, and the new ones installed with new rubber seals and lubricants to ensure proper sealing and function. After reassembly, the brake system must be bled to remove any trapped air and restore proper hydraulic pressure.

While the Subaru Exiga's all-disc brake setup eliminates the need for brake wheel cylinders, understanding their role in braking systems overall is useful. If the Exiga ever needs brake servicing, owners will be dealing with brake calipers, rotors, and pads rather than drums and wheel cylinders. Regular servicing involves checking brake fluid levels, inspecting calipers and pads, and replacing parts as needed to keep braking responsive and safe.

So for owners of the 2017 Subaru Exiga, there is no need to worry about brake wheel cylinders because they simply aren't part of this vehicle's braking design. Instead, the focus should be on monitoring and maintaining the disc brake components to ensure smooth and reliable stopping power. If uncertain about what your vehicle needs during servicing, it's always best to consult a trusted Subaru specialist who will provide tailored advice and maintenance specific to the Exiga's systems.
