How To Fix Squeaking Subaru Brakes

There's a distinct, unnerving feeling that accompanies the sound of squeaking brakes, especially when you're behind the wheel of a Subaru, a brand synonymous with safety and reliability. A squeak every now and then might be considered normal due to various conditions, but consistent noise often indicates a need for attention. This article will walk you through understanding and addressing squeaking brakes, ensuring that your Subaru remains both safe and silent on the roads.

Understanding the Source of the Squeak

Brake squeaks in Subarus, like in many vehicles, can arise from a variety of sources. The sound itself is usually a result of vibration between the brake pads and the brake rotors. This vibration can be attributed to multiple factors:

• Worn-out brake pads: Over time, the material of the brake pads wears down. When they become thin, most brake pads have a built-in metal wear indicator that produces a squeak to signal the need for replacement.
• Presence of brake dust: Over time, brakes generate dust from the friction between pads and rotors. Accumulated brake dust can produce a squeaky noise when brakes are applied.
• Environmental conditions: In certain humid or wet conditions, a thin layer of rust can form on the brake rotors. When the brake pads rub against these rust-covered rotors, a squeak may be produced.

Brake Inspection and Cleaning

Sometimes, the solution to a squeaking brake problem is as simple as cleaning. Debris, dust, and tiny stones can get trapped in the brake system, leading to that familiar squeak. A thorough inspection can help identify these minor issues:

• Safely lift your Subaru using a jack, ensuring it's secure.
• Remove the wheel to get a clear view of the brake system.
• Inspect the brake pads. If they seem thin or you notice the metal wear indicator, it's time for a replacement.
• Clean the brake assembly with a brake cleaner. Ensure you wear safety glasses and gloves during this process. The cleaner will help dissolve and remove brake dust and other contaminants.

Brake Pad and Rotor Replacement

If a thorough cleaning doesn't resolve the squeak, or if you identify wear and tear in the brake pads or rotors, it might be time for a replacement:

• When choosing new brake pads, consider investing in high-quality ceramic pads. They tend to produce less dust and are less likely to squeak.
• If your rotors show signs of wear, such as deep grooves, scoring, or warping, they should be replaced or resurfaced. Ensure the rotors you select are compatible with your Subaru model.
• After replacing brake pads or rotors, it's crucial to "bed in" the brakes. This process involves applying the brakes at specific intervals to generate heat and allow the new components to settle, which can reduce future squeaks.

Lubrication and Anti-Squeal Products

If the brakes are in good shape, but the squeak persists, consider using lubrication or anti-squeal products:

• Brake lubricant can be applied to the back of the brake pads (never the side that contacts the rotor). This can help reduce the vibration and subsequent squeak.
• Anti-squeal sprays and compounds, available at automotive stores, can be applied to the brake pads and rotors, forming a protective layer that reduces noise.

A squeaking brake is not just an auditory annoyance; it can be a signal that your Subaru's safety is compromised.
