Brake Rotors on the 2017 Subaru Impreza: What You Need to Know

When it comes to the braking system on the 2017 Subaru Impreza, brake rotors play a crucial role. Brake rotors, also known as brake discs, are an essential component in disc brake systems, which are used on this model both at the front and rear wheels. The 2017 Subaru Impreza utilises disc brakes all around, meaning brake rotors are definitely fitted to this vehicle. These rotors work together with brake pads to help stop the car safely and efficiently.

The main purpose of brake rotors is to provide a solid surface for the brake pads to clamp onto when the driver presses the brake pedal. When this happens, hydraulic pressure pushes the brake pads against the spinning rotor, generating friction. This friction slows down the rotation of the wheels, bringing the Impreza to a stop. The rotors have to absorb and dissipate the heat generated by this friction so that braking remains effective and the braking components don't overheat or warp.

On the 2017 Subaru Impreza, the brake rotors are typically made from cast iron, a material selected for its durability and excellent heat dissipation properties. Over time, however, rotors can wear down, become warped, or develop grooves from constant contact with the brake pads. This wear can affect braking efficiency and create vibrations or noise when braking. Because of this, regular inspection and maintenance of brake rotors are important for vehicle safety and performance.

When servicing a 2017 Subaru Impreza, mechanics will usually inspect the brake rotors alongside the brake pads. Here are some common signs that a rotor might need replacing or resurfacing:

• Visible scoring or deep grooves on the rotor surface
• Warping that causes the steering wheel to shake when braking
• Cracks or excessive rust on the rotor
• Rotor thickness below the manufacturer's minimum specification

If any of these issues are detected, the rotors may need to be machined to resurface them, or in many cases, replaced altogether. The minimum thickness specification is particularly important because rotors that are too thin can be unsafe and prone to cracking under hard braking.

Brake rotors on the 2017 Subaru Impreza should be checked during routine servicing intervals or sooner if there are any signs of brake problems such as unusual noises, reduced braking performance, or vibration. Regular maintenance helps to ensure that the brakes perform reliably, which is essential for everyday driving safety. It's a good idea for Impreza owners to follow the service schedule recommended in the vehicle's owner manual, where brake inspection is normally included.

Replacing brake rotors when necessary is often paired with fitting new brake pads. New pads can cause rapid wear to old, worn rotors, while installing new rotors with old pads might not give the smoothest braking experience. Pairing both new pads and new rotors usually delivers the best results in terms of braking smoothness and longevity.

Brake rotors also require clean and corrosion-free mounting surfaces during installation to ensure proper fitment and avoid uneven braking. Subaru dealerships and reputable auto workshops will have the correct tools and knowledge to service the 2017 Impreza's braking system properly.

In some cases, upgrading brake rotors to higher performance variants, such as slotted or drilled rotors, is an option for drivers wanting enhanced braking, especially under demanding conditions. However, for most everyday drivers, the standard OEM rotors fitted on the 2017 Impreza provide a great balance of performance, durability, and cost-effectiveness.

So, for anyone owning or servicing a 2017 Subaru Impreza, paying attention to the condition of the brake rotors is a key part of brake system maintenance. Efficiently working brake rotors alongside good quality brake pads ensure the vehicle stops safely, quietly, and smoothly every time. Neglecting this component could lead to early wear, compromised safety, and potentially costly repairs down the track.
