2020 Subaru Forester Brake Pad & Rotor Specs

Quick Reference: 2020 Forester Brake Specifications

The fifth-generation Subaru Forester is a capable and safe crossover, but its braking system requires regular attention to maintain its performance. Whether you're a DIYer planning a weekend brake job or a discerning owner wanting to be informed, this guide covers all the essential specifications for your 2020 Forester.

How to Choose Brake Pads

Selecting the right brake pad is a balance between performance, noise, dust, and longevity. The Forester came from the factory with ceramic-based pads, which are a great all-around choice. Here's how the options break down:

• Ceramic Pads: This is the original equipment (OE) style. They offer quiet operation, low dust, and predictable stopping power for daily driving. They are gentle on rotors, helping them last longer. For the vast majority of Forester owners, a quality name-brand ceramic pad (like those from Akebono, Bosch, or Wagner) is the perfect replacement.

• Semi-Metallic Pads: These pads contain metal fibers, which provide excellent heat dissipation and a firmer pedal feel. They are a good upgrade for drivers who live in mountainous areas, tow light trailers, or simply prefer a more aggressive initial bite. The trade-offs are increased brake dust and potentially more noise than ceramics.

• Heavy-Duty / Performance Pads: Brands like Power Stop (e.g., their Z23 Evolution Sport series) offer carbon-fiber ceramic formulas designed for spirited driving and enhanced thermal capacity. These are ideal for the owner who has added performance modifications or uses their Forester for more demanding tasks. They provide the highest friction levels but may also produce more dust and wear rotors slightly faster.

Typical Service Life

The lifespan of your brakes is heavily dependent on your driving style and environment. A driver who commutes primarily on the highway will see significantly longer life than one who navigates hilly city streets.

• Brake Pads: Expect to replace the front brake pads on a 2020 Forester every 30,000 to 50,000 miles. The rear pads handle less of the braking force and typically last longer, often in the 50,000 to 70,000-mile range.

• Brake Rotors: Rotors generally last through two sets of brake pads. However, if you experience vibration (warping) or wear them down below the minimum thickness, they must be replaced. A "pad-slap," which is installing new pads on old, un-surfaced rotors, is not recommended. This practice can lead to uneven pad deposits, noise, and reduced braking performance. For best results, always install new pads and new rotors at the same time.

Common Brake Issues for This Generation

The 2019+ Forester generation has a generally reliable braking system. However, like any vehicle, it has a few quirks owners should watch for:

• Electronic Parking Brake (EPB): The most significant change for this generation is the EPB. To service the rear brakes, you MUST put the system into its electronic "Service Mode" using a compatible scan tool or a specific sequence of actions in the cabin. Failure to do so before compressing the rear caliper piston will damage the electronic actuator inside the caliper, resulting in a costly repair.

• Slide Pin Seizures: Subaru calipers use slide pins to allow the caliper to float and apply even pressure. These pins require proper cleaning and lubrication with high-temperature silicone paste at every brake service. If neglected, they can seize, causing the pads to wear unevenly and rapidly.

• Rotor Warping: While not rampant, some owners report brake pedal pulsation, a symptom of warped front rotors. This is often caused by improper lug nut torque or heavy braking in mountainous terrain. Using high-quality rotors and ensuring wheels are torqued to spec can mitigate this issue.

Brake Job Cost Estimate

Brake service costs can vary widely by region and shop labor rates. Here are some ballpark figures for a professional brake job on a 2020 Forester:

• Front Brakes (Pads & Rotors): $450 - $700
• Rear Brakes (Pads & Rotors): $400 - $650 (The EPB service procedure can add to the labor time)
• All Four Brakes (Pads & Rotors): $850 - $1,300

Costs can be reduced by using aftermarket parts, but we recommend sticking to reputable brands. A complete brake fluid flush is also recommended every 2-3 years or 30,000 miles and may add $100-$150 to the service.
