Subaru Impreza: Understanding Brake Issues

Subaru has cultivated a strong reputation for producing vehicles that are not only reliable but also built to endure the test of time. The Subaru Impreza, a popular model within their lineup, often garners praise for its practicality, all-wheel-drive capability, and comfortable ride. However, like any vehicle, the Impreza is not immune to common issues that can affect its performance and longevity. One area that has drawn attention from drivers and automotive experts alike is the braking system. This article delves into the specifics of brake-related concerns with the Subaru Impreza, aiming to provide a comprehensive understanding for current and prospective owners.

Does the Impreza have underpowered brakes?

The question of whether the Subaru Impreza possesses underpowered brakes is a recurring one among owners. While the Impreza is generally lauded for its handling and all-wheel-drive system, some drivers have reported that the brakes feel less responsive than expected, particularly during demanding driving conditions or on longer descents. This perception can stem from various factors, including the intended design of the braking system for everyday driving versus spirited performance, and the vehicle's overall weight and capabilities.

It's important to distinguish between brakes that are 'underpowered' for a specific driving style and brakes that are inherently faulty. Many Subaru drivers rave about the Impreza's handling, especially when taking sharp corners at high rates of speed. However, the 2004 Impreza, for instance, is noted to have a known issue with the steering rack bushes, which can lead to poor control and sloppy handling. While this isn't directly a brake issue, it highlights how component wear can affect the overall driving experience. When it comes to brakes specifically, the concern often isn't just about stopping power but also about how the braking system interacts with other vehicle components.

Brakes Wear Out Quickly

A common complaint among new Impreza owners is that the brakes seem to wear out at an accelerated rate. Some automotive experts suggest that this could be due to the brakes being underspecified for the vehicle's size and weight, especially when considering the added traction provided by the standard all-wheel-drive system. The all-wheel-drive system can allow for higher cornering speeds and quicker acceleration, which can, in turn, lead to more frequent and harder braking if the driver is not mindful of the vehicle's capabilities.

Symptoms of brakes wearing out quickly can include:

• Vehicle noise when applying the brake: This can manifest as squealing, grinding, or clicking sounds, often indicating worn brake pads or rotors.
• Feeling like you have to press the brake harder: A spongy or less responsive brake pedal can suggest issues with brake fluid, air in the lines, or worn brake components.

The good news is that this is often an easy fix. For drivers unhappy with the Impreza's brake performance or concerned about premature wear, replacing the brake pads and potentially the rotors is a viable solution. It's generally recommended to replace brakes on both sides of the vehicle simultaneously to ensure balanced braking. After this upgrade, you should find that the brakes last longer and perform more consistently.

Underpowered Brakes Can Affect Overall Suspension Health

Beyond the direct performance of the brakes, a more significant concern for some Impreza drivers is how the braking system's perceived underperformance can indirectly affect the overall health of the suspension system. If the brakes are not providing sufficient stopping power, drivers might compensate by braking earlier or more frequently, or by relying more heavily on engine braking. In some instances, particularly with older models or those driven hard, this can put additional stress on other drivetrain components.

One specific mention points out that if the ride is extremely bumpy and tosses you around the cabin a bit, you might want to reconsider a particular Impreza or be aware that the vehicle's velocity joints might need replacement soon. While this isn't a direct consequence of brake underpowering, it highlights how a less-than-optimal driving experience, which can be exacerbated by braking issues, might correlate with other wear-and-tear components.

Brake Lights Not Working

Another brake-related issue that can affect Subaru Imprezas, particularly the 2010-2016 models, is the brake lights not working. For most vehicles, this is a straightforward fix: a burnt-out bulb. It's always advisable to replace both brake light bulbs at the same time, as they tend to have similar lifespans and often fail close together.

However, if you've replaced a bulb and it still doesn't work, or if it burns out again quickly, there might be a more significant underlying issue. In the 2010-2016 Impreza models, there's a possibility of silicone gas seeping into the light housing, causing damage. If this occurs, the solution typically involves replacing the brake light switch. This switch is crucial for activating the brake lights when the pedal is pressed, and a faulty one can lead to premature bulb failure or complete malfunction.

Addressing Impreza Brake Concerns: What You Can Do

If you're experiencing issues with your Subaru Impreza's brakes, whether it's rapid wear, a feeling of underpowering, or malfunctioning brake lights, here are some steps you can take:

1. Regular Maintenance is Key

Adhering to a regular maintenance schedule is paramount for any vehicle, and the Impreza is no exception. This includes:

• Brake Inspections: Have your brake pads, rotors, and fluid checked at every service interval.
• Fluid Checks: Ensure your brake fluid is at the correct level and free of contaminants.
• Tyre Rotation: While not directly related to brakes, proper tyre maintenance ensures even wear and optimal handling.

2. Consider Upgrades for Improved Performance

If you find the stock brakes are not meeting your expectations, consider aftermarket upgrades:

• Performance Brake Pads: Opt for higher-quality or performance-oriented brake pads that offer better heat resistance and stopping power.
• Performance Rotors: Slotted or drilled rotors can help dissipate heat more effectively, reducing the risk of brake fade.
• Braided Stainless Steel Brake Lines: These can improve pedal feel and responsiveness by reducing the expansion of the brake lines under pressure.

3. Test Drive and Inspection for Used Imprezas

When considering a used Subaru Impreza, pay close attention to the brakes during the test drive. Listen for unusual noises, feel the pedal for sponginess or excessive travel, and test the brakes under various conditions if possible. If you're considering a purchase, it's always a wise decision to have the vehicle inspected by an independent mechanic who can identify any potential brake-related issues before you commit.

Comparison of Brake Pad Types

When it comes to replacing brake pads, understanding the different types available can help you make an informed decision:

Even if you replace your Monza's brake pads with OEM-grade factory-style brake pads that are not made by Chevrolet, they are still considered aftermarket Monza parts. Over the course of a vehicle's life, it almost certainly will have aftermarket parts installed at some point, even if the vehicle is never actually 'modded out'. This is also true for the Impreza; choosing quality aftermarket parts can often provide superior performance and longevity compared to standard OEM replacements.
