Parts for your 2016 Subaru Forester-Brake wheel cylinders

Are brake wheel cylinders used on a 2016 Subaru Forester?

Short answer: no, a 2016 Subaru Forester doesn’t use brake-wheel-cylinders. That part is specific to drum brake setups, and the SJ-series Forester (MY2016) runs disc brakes front and rear, so it uses calipers with hydraulic pistons instead of wheel cylinders.

This isn’t just workshop folklore. The 2016 Forester Service Manual (Brake section, via Subaru Technical Information System) specifies ventilated front discs and solid rear discs with single-piston sliding calipers. Subaru Australia’s 2016 Forester specification sheets also list four-wheel disc brakes across the range. The Owner’s Manual for the same model year references disc brake maintenance and fluid servicing with no mention of rear drum hydraulics. Because wheel cylinders are only found in hydraulic drum brakes, they’re not fitted to this vehicle.

Why Subaru doesn’t use brake-wheel-cylinders here comes down to design. Disc brakes offer better heat management, more consistent pedal feel, and easier servicing—right in line with the Forester’s all-rounder brief. While the rear rotors do house a small mechanical parking brake (drum-in-hat), it’s cable-actuated, not hydraulic—so there’s still no wheel cylinder hiding in there.

If someone is chasing a “wheel cylinder leak” on a 2016 Forester, what they’re probably seeing is one of these instead:

• Rear caliper piston seal seepage
• Banjo bolt copper washers or hose-to-caliper union weeping
• Flexible brake hose cracking or hard line corrosion

For brake service on a 2016 Forester, the smart play is to focus on the bits it actually has:

• Inspect and lubricate caliper slide pins, ensure even pad wear.
• Check caliper piston boots and seals for tears or leaks, rebuild or replace if needed.
• Replace pads and machine/replace rotors when below spec or if there’s vibration.
• Flush brake fluid every two years with the correct spec, keep the system free of moisture and air.
• Adjust and inspect the rear parking brake shoes inside the hat of the rotor, replace the linings if worn or contaminated.

So if the brief is “2016-subaru-forester/brake-wheel-cylinders,” the relevant advice is actually caliper care, fluid health, and parking brake shoe adjustment—because wheel cylinders simply aren’t part of the setup on this model.

Popular questions

Do 2016 Subaru Foresters have brake-wheel-cylinders?
No. They run disc brakes front and rear with calipers, not drum brakes with wheel cylinders. The rear parking brake uses a drum-in-hat design that’s cable-operated, so there’s still no hydraulic wheel cylinder involved.

What should be serviced instead of brake-wheel-cylinders on a 2016 Forester?
Focus on the calipers (piston seals and slide pins), pads, rotors, and brake fluid flushes every two years. Also inspect and adjust the parking brake shoes inside the rear rotor hats.

I’ve found brake fluid near a rear wheel—what could be leaking?
Likely culprits are the rear caliper piston seal, the banjo bolt washers, the flexible hose, or a hard line. On this model it won’t be a wheel cylinder because there isn’t one.
