Parts for your 2012 Subaru Forester-Brake calipers

2012 Subaru Forester brake calipers — what they do and how to keep them happy

Brake calipers are absolutely fitted and relevant on the 2012 Subaru Forester. The Subaru Workshop/Service Manual for the 2012 Forester (SH, Brake—BR section) specifies floating single‑piston front calipers, and Subaru’s genuine parts catalogue (Group 26: Brake) lists caliper assemblies for both axles on most trims. Common aftermarket fitment catalogues from brands like Bendix and Bosch also show front and rear calipers for 2012 Forester variants in AU/NZ, noting that some entry models in certain markets may use rear drums—either way, the front axle uses calipers across the range.

On this Forester, the brake caliper’s job is to clamp the pads onto the rotor when the driver hits the pedal, converting hydraulic pressure into stopping force. Floating calipers slide on greased guide pins so both pads squeeze evenly. Most AU/NZ 2012 Foresters run disc brakes and calipers at both ends, while the handbrake typically uses a small drum-in-hat inside the rear rotor.

Good calipers keep stopping distances short and pedal feel consistent. If a caliper binds or leaks, the car can pull to one side, chew through pads, or overheat a wheel. During regular servicing, a tech should inspect for torn dust boots, wetness around the piston or bleeder, uneven pad wear, and sticky slides. Every pad change is a solid time to clean and lubricate the guide pins with a proper high‑temp, rubber‑safe brake grease—avoid anything that swells rubber or burns off under heat.

• Watch for tell‑tales: steering pull under braking, a hot wheel, burning smell, or rapid pad wear.
• Replace if the piston’s seized, the bore is pitted, boots are torn, or the bleeder’s snapped.
• Rebuilds are viable with seal kits if the caliper body is sound, otherwise go new or quality reman.

When fitting new calipers on a 2012 Forester, refresh the copper washers on banjo bolts, torque all hardware to spec from the service manual, and bleed the system in the correct sequence. Use fresh brake fluid (DOT 3 or DOT 4 as specified on the cap/manual—don’t mix with DOT 5 silicone). After install, bed‑in the pads as per the pad maker’s instructions so the rotor and pad face in nicely.

As part of ongoing care in Aussie and Kiwi conditions—think coastal air, rain, and the odd gravel run—inspect the calipers every service or 10,000–15,000 kilometres. Flush brake fluid about every two years. Keeping the slides moving and seals tidy will save tyres, rotors, and a fair bit of wallet pain.

Popular questions about 2012 Subaru Forester brake calipers

How often should the calipers be serviced?
They should be inspected at every service or roughly every 10,000–15,000 kilometres. Clean and re‑grease the slide pins at each pad change, and replace any torn boots. Brake fluid should be flushed about every two years to keep corrosion at bay.

Can the original calipers be rebuilt, or is replacement better?
If the caliper body and piston aren’t rust‑pitted, a quality seal kit and new boots can bring them back to life. If the bore is rough or the slider bores are flogged out, a new or remanufactured caliper is the smarter option. Many remans offer a core return to keep costs down.

What are common signs a 2012 Forester caliper is sticking?
Typical clues include the car dragging or pulling under braking, one wheel running noticeably hotter, a burning smell after a drive, and uneven or fast pad wear on one side. You might also notice worse fuel economy from the extra drag.
