Parts for your 2017 Subaru Outback-Brake wheel cylinders

Brake Wheel Cylinders on the 2017 Subaru Outback

When it comes to the braking system of the 2017 Subaru Outback, the term brake wheel cylinders might come up, but it is important to understand whether this component is actually part of the vehicle's setup. The 2017 Subaru Outback does not use brake wheel cylinders in its braking system. This is because the Outback employs a modern disc brake system on all four wheels, specifically ventilated disc brakes in the front and solid disc brakes at the rear. Brake wheel cylinders are typically found only in drum brake systems, which the 2017 Outback does not have.

So, what are brake wheel cylinders, and why doesn't the 2017 Subaru Outback use them? Brake wheel cylinders are small hydraulic components used exclusively in drum brakes. Their job is to push the brake shoes outwards against the inside of the drum when hydraulic pressure is applied, helping slow down or stop the vehicle. Inside a brake wheel cylinder sit pistons that respond to brake fluid pressure, moving the shoes into contact with the drum to generate braking force. You'll find these components mainly in older or smaller cars, or in the rear brakes of vehicles that still use drum brake assemblies.

The 2017 Subaru Outback, however, opts for disc brakes all around. Disc brakes use hydraulic calipers coupled with brake pads that squeeze against a metal disc (rotor) to stop the vehicle, eliminating the need for wheel cylinders. This design offers superior performance - better heat dissipation, more consistent stopping power, and simplified maintenance compared to drum brake systems.

Since the 2017 Subaru Outback doesn't have brake wheel cylinders, owners and mechanics don't need to worry about servicing or replacing them. Instead, the focus turns to maintaining the disc brake components such as brake pads, calipers, and rotors. Regular maintenance on these parts ensures the Outback's brakes remain responsive and safe.

That said, even if the 2017 Subaru Outback's braking system does not feature brake wheel cylinders, understanding their role can be useful, particularly if someone is familiar with older car models or other vehicles that still use drum brakes. If this vehicle had brake wheel cylinders, the maintenance tips and replacement advice would focus on key aspects such as:

• Checking for leaks around the wheel cylinder seals, as any brake fluid leak compromises braking efficiency and can allow dirt and moisture in, causing corrosion.
• Inspecting the pistons and rubber seals within the cylinder for wear or damage that may lead to sticking or reduced braking response.
• Replacing the wheel cylinders during brake servicing if any signs of deterioration or leakage are evident, as these parts play a critical role in the hydraulic braking function.

For a vehicle with drum brakes, brake wheel cylinder servicing usually occurs during brake shoe replacement or a comprehensive brake system inspection. Technicians carefully dismantle the drum assembly, examine the wheel cylinders, and replace or rebuild them to maintain the system's integrity. Proper lubrication and seal replacement ensure smooth operation and prevent brake failure.

Since the 2017 Subaru Outback relies on disc brakes, its routine brake servicing involves checking brake pad thickness, rotor wear, and caliper function rather than any wheel cylinder concerns. Drivers should keep an eye on brake fluid levels and ensure the hydraulic system is free from leaks for the safest performance.

In all, owners of the 2017 Subaru Outback can rest easy knowing that their vehicle benefits from a modern braking setup without brake wheel cylinders. The disc brake system offers reliable stopping power and easier maintenance, helping keep the Outback safe and ready for any journey across Australian roads.
