• 2010-2019 Subaru Outback (4th-5th gen, 2.5L H4 / 3.6L H6, AWD) - all trims including 2.5i, 3.6R, Limited, Premium
• 2014-2018 Subaru Forester (SJ, 2.0L / 2.5L H4, AWD) - models with 17-inch disc brakes only
• 2015-2021 Subaru WRX (VA, 2.0L Turbo H4, AWD) - standard steel caliper applications only; not for Brembo 4-piston upgrade

Fitment Notes

• Front axle position only.
• WRX application: Fits the standard Akebono single-piston front caliper configuration only. Not compatible with WRX or WRX STI models equipped with the optional Brembo 4-piston front calipers.
• Forester application: Fits models with 17-inch disc brakes only. Verify disc size before ordering.
• Does not fit the Subaru WRX STI, which uses a factory Brembo 4-piston front brake system.
• Replaces Subaru OE Part Number: 26296AJ001.

Features

• Prime Ceramic (NAO) compound delivers low brake dust output - keeps Subaru alloy wheels cleaner between washes on all confirmed applications.
• Formulated specifically for the North American market, matching the OE Akebono caliper interface across Legacy, Outback, Forester, WRX, and Tribeca platforms.
• Multi-layer ESE (Elastomer-Steel-Elastomer) anti-squeal shim dampens vibration from pad-to-rotor contact at the front Akebono caliper interface.
• Chamfered and slotted pad design reduces initial bite noise and enhances pad heat evacuation under sustained front-axle braking load.
• Factory thermal scorch treatment minimizes break-in fade and shortens the bedding window after installation.
• OE Direct Moulding Pressing Process ensures dimensional accuracy and precise fit to the Akebono front caliper on all confirmed applications.
• Corrosion-resistant coated backing plate extends pad life in winter driving conditions typical of Subaru AWD markets.
• Sold as a 2-wheel front set with all required installation hardware included.

Product Description

The Brembo P78017N is a Prime Ceramic Front Disc Brake Pad Set engineered as a direct OE replacement for the Akebono front caliper system shared across multiple Subaru platforms - including the Legacy (2005-2019), Outback (2010-2019), Forester (2014-2018), WRX (2015-2021), B9 Tribeca (2006-2007), and Tribeca (2008-2014). This single pad covers a broad span of Subaru's AWD lineup, replacing Subaru OE part number 26296AJ001.

The NAO ceramic compound produces minimal brake dust, which is a particular benefit on Subaru vehicles typically used in all-weather conditions where grime and salt residue already challenge wheel appearance. The multi-layer ESE shim and chamfered/slotted pad geometry suppress brake noise and vibration at the front caliper, while Brembo's factory thermal scorch treatment ensures consistent friction from the first stop and minimizes the typical break-in fade period.

Two application-specific notes: on the WRX, this pad fits the standard Akebono single-piston front caliper only and is not compatible with vehicles equipped with the optional Brembo 4-piston front caliper upgrade. On the Forester, fitment is limited to models with 17-inch disc brakes. WRX STI models, which use a factory Brembo 4-piston front system as standard equipment, are not covered by this part number.
