Parts for your 2017 Subaru Legacy-Brake calipers

Brake Calipers on the 2017 Subaru Legacy: Purpose and Maintenance Tips

The 2017 Subaru Legacy definitely uses brake calipers as part of its braking system. Brake calipers are essential components in almost every modern vehicle equipped with disc brakes, and the Legacy is no exception. These small but mighty parts play a crucial role in keeping the vehicle safe on the road by allowing the car to slow down and stop effectively.

So, what exactly do brake calipers do on a 2017 Subaru Legacy? When the driver presses the brake pedal, hydraulic fluid is pushed through the brake lines and into the calipers. The calipers then squeeze the brake pads against the surface of the brake rotors, creating the friction needed to stop the wheels from spinning. Without the calipers performing their job properly, the braking system would not be able to function efficiently, leading to longer stopping distances and potentially unsafe driving conditions.

Since the Subaru Legacy uses disc brakes with calipers at each wheel, these parts regularly encounter heat and wear over time. This means that keeping an eye on the brake calipers is an important aspect of any maintenance routine to ensure the vehicle continues to perform at its best and remains safe.

One of the casualties of wear and tear on brake calipers is the piston seals inside them. These seals can harden or crack over time, which might cause the pistons to stick or leak brake fluid. If that happens, the calipers may not press the brake pads correctly against the rotors, resulting in uneven braking or even brake failure. Regular inspections during servicing will help catch these issues before they become dangerous.

When it comes to replacing brake calipers on the 2017 Subaru Legacy, it's generally advised to replace them in pairs - that is, replace both front calipers or both rear calipers at the same time. This helps maintain balanced braking performance and prevents one side from braking harder than the other, which could cause instability or uneven tyre wear.

Maintenance of brake calipers usually involves cleaning, lubricating, and checking for any signs of damage, sticking, or leaking. The caliper slide pins, which allow the caliper to move smoothly when braking, need to be kept clean and greased to stop the calipers from seizing up. If these slide pins seize, it can lead to the brakes dragging, overheating, and premature wear of the pads and rotors.

Brake fluid quality is also crucial for the health of the braking system. Since brake calipers operate hydraulically, old or contaminated brake fluid can reduce the system's efficiency and cause corrosion inside the calipers. Subaru recommends regular brake fluid changes as part of the servicing schedule for the Legacy, usually around every two years or so, depending on usage conditions.

If drivers notice any odd noises like squealing or grinding, uneven brake pad wear, a pulling sensation to one side when braking, or a soft brake pedal, it could be an indication that the brake calipers need attention. Addressing these signs early can prevent further damage and higher repair costs down the track.

Interestingly, braking performance can also be affected by environmental factors. For drivers living in coastal areas, salty air can accelerate corrosion on metal brake components, including calipers. This makes regular inspections and timely maintenance even more important to ensure the calipers remain in good working order over the years.

For DIY enthusiasts, handling brake caliper issues may involve replacing the caliper seals, cleaning, or even swapping out the entire caliper assembly. However, due to the critical safety nature of the braking system, it is wise to have a qualified mechanic perform any brake caliper servicing or replacement on a 2017 Subaru Legacy. Professional service can include precise bleeding of the brake lines to remove any trapped air, ensuring optimal brake pedal feel and safety.

Overall, brake calipers are definitely a vital part of the 2017 Subaru Legacy's braking system. Taking care of them through regular checks, fluid changes, and timely replacements ensures that the Legacy remains a safe and reliable vehicle on Australian roads. With proper maintenance, the brake calipers will continue to provide the smooth and effective braking performance expected from Subaru's well-regarded engineering.
