Parts for your 2015 Subaru Legacy-Brake shoes

2015 Subaru Legacy/Liberty brake shoes — are they used?

For the 2015 Subaru Legacy (known as Liberty in Australia), brake shoes aren’t used. Technical documentation confirms this: the 2015MY Subaru Legacy/Outback Workshop Manual (Brake > Electronic Parking Brake) specifies an electronic parking brake that applies the rear disc brake calipers, not a drum-in-hat setup. The Subaru Global Parts Catalogue (FAST) for BN/BS series lists rear pads, rotors and caliper-motor assemblies, but no parking-brake shoe set. Major aftermarket catalogues for this model year also show plain rear rotors without an internal drum, which aligns with a shoe-less design.

Why no brake shoes? Subaru moved to four-wheel disc brakes with a caliper-integrated electronic parking brake (EPB) on the BN/BS platform. This design improves packaging, reduces parts count, integrates neatly with stability/hold features, and provides consistent parking-brake force via a motor at each rear caliper. With no internal drum, there’s simply nowhere for traditional parking-brake shoes to live.

What should owners service instead? Focus on the rear brake pads, rotors and the EPB mechanism. When replacing rear pads, the EPB must be placed into service mode (as outlined in the Subaru Workshop Manual) so the caliper motors retract safely. Use suitable scan-tool or manual service-mode procedures, torque hardware to spec, and perform a proper bed-in of new pads and rotors. Keep slide pins clean and lubricated, inspect caliper boots, and flush brake fluid at recommended intervals.

• Check rear pad thickness at every service, many drivers see 30,000–70,000 km from a set, depending on conditions.
• If the EPB is noisy or won’t release, test the caliper motors and wiring before assuming pad or rotor faults.
• If the vehicle has been in mud/sand, rinse brakes and schedule a check, grit can accelerate pad and rotor wear.

Bottom line: on a 2015 Legacy/Liberty, “brake shoes” aren’t a relevant part. The correct rear braking service revolves around pads, rotors, calipers and EPB procedures.

FAQs

Does a 2015 Subaru Legacy/Liberty have brake shoes?
No. This model uses rear disc brakes with an electronic parking brake that squeezes the rear calipers. There’s no drum-in-hat assembly and no parking-brake shoe set listed in the Subaru parts catalogue for the BN/BS series.

How is the parking brake serviced on this model?
Before replacing rear pads, the EPB must be put into service mode so the caliper motors retract. Follow the Subaru Workshop Manual procedure, use a suitable scan tool if required, torque everything correctly, then bed-in the brakes and confirm EPB operation.

What rear brake parts are typically replaced?
Rear pads and rotors are the regular wear items. Hardware such as pad clips and slide pin boots should be inspected and renewed if tired. EPB motors and rear calipers are usually long-lived but should be checked if there are warning lights, noises or binding.
