This automotive maintenance tutorial was specifically written to assist owners of the fourth generation (2014, 2015, 2016, 2017 and 2018) Subaru Forester SUV in changing the rear disc brake pads and lubricating the caliper slider pins.

Owners of other Subaru vehicles such as the Outback, Impreza, Legacy, XV Crosstrek, WRX, BRZ, SVX, Tribeca, Exiga, Trezia, Levorg and Baja may also find these DIY instructions to be helpful.

A few compatible replacement sets of new rear brake pads with their part numbers are as follows: Wagner ZD1114, TRW TPC1114, Subaru 26696 FJ000, ACDelco 14D1114CH, Akebono ACT1114 and Bosch BC1114.

The tools and other items needed to complete this procedure include a lug nut wrench, a floor jack, two jack stands, a 14mm socket with a 3/8" drive ratchet, an "F" clamp and a tube of brake caliper grease.

Caliper, Bracket & Rotor
The first few steps are to park the SUV on a level surface, turn off the ignition and place the transmission in park.

Make sure that the emergency / parking brake is not engaged. (If the parking brake isn't released, you won't be able to pull the rear brake caliper off the old pads and out of the bracket.)

Place wheel chocks on both sides of the front tires to prevent the vehicle from moving.

I prefer to work on one side of the vehicle at a time to keep three tires on the ground for extra safety.

Slightly loosen the five lug nuts on the rear wheel by turning them about 1/4 turn in the counterclockwise direction with the tire iron.

Raise the rear of the car with the floor jack and securely support it with at least two jack stands.

(The jack point is marked on the pinch weld by a triangle.)

Spin off the five lug nuts and set them aside in a safe place.

Pull off the rear wheel to reveal the caliper, bracket, rotor and suspension.

Loosen Upper Caliper Bolt
The rear brake caliper is held in place to the bracket by two bolts located on the back side of the caliper with the bolt heads facing in towards the center of the SUV.

Loosen the two caliper bolts by turning them in the clockwise direction (as seen from the outside of the vehicle) with the 14mm socket and a 3/8" drive ratchet.

Wear Bar - Bottom Inner Pad
Carefully lift the caliper out of the bracket and off the old brake pads.

Rest the caliper on the rotor or suspend it from the suspension spring with a bungee cord or some twine.

Try to avoid bending, kinking or stressing the rubber brake fluid hose.

Pull the old inner brake pad out of the bracket.

You'll notice that there is a wear indicator bar or "squeal" bar situated at the bottom of the inner pad.

Top Abutment Clip
Pull the old outer brake pad out of the bracket.

If your new set of rear brake pads includes replacement hardware, pull the old pad abutment clips (or "anti-rattle" clips) out of the top and bottom of the bracket.

Apply a thin layer of brake caliper grease to the parts of the new pad abutment clips that will come in contact with the bracket and the "ears" of the new brake pads.

Push the new pad abutment clips into the top and bottom of the bracket until they are fully seated.

Attach "F" Clamp To Caliper

In order for the brake caliper to operate smoothly, the two caliper slider pins or "guide bolts" need to be well lubricated.

Pull the two caliper slider pins out of their rubber dust boots.

Apply a thin layer of brake parts lubricant grease to the smooth parts of the two caliper slider pins.

Push the caliper slider pins back into their rubber dust boots within the bracket.

In order for the caliper to fit over the thicker new brake pads, the caliper piston need to be compressed or "retracted" back into the caliper assembly.

Attach the "F" clamp to the caliper and use the back of an old brake pad to evenly distribute the pressure across the piston.

Compress Caliper Piston
Move to the right rear area of the engine bay and locate the brake fluid reservoir which has a yellow plastic cap on top.

Twist off the brake fluid reservoir cap in the counterclockwise direction and set it aside in a safe place.

Slowly turn the "F" clamp handle in the clockwise direction to push back the caliper piston until it is flush with the rubber dust boot that surrounds it.

Try to avoid pinching or damaging the rubber dust boot that surrounds the piston.

Once the piston is fully compressed, detach the "F" clamp and discard the old brake pad.

Install New Outer Pad

Wear Bar - Bottom Inner Pad
Replace the reservoir cap as soon as possible since brake fluid hygroscopic (absorbs moisture from the air).

Thoroughly clean off the brake rotor, caliper bracket, brake caliper assembly and the lug studs with brake parts cleaner spray. Do not use compressed air or blow with your mouth to clean off the brake parts. Inhaling brake dust can be harmful to your health since brake dust can be carcinogenic (cancer causing) if inhaled.

Apply a thin layer of brake parts lubricant grease to any area where there is metal to metal contact such as the outer lip of the caliper piston. Do not apply brake caliper grease to the friction surface of the new pads or the rotor.

 If your Forester previously exhibited shuddering, pulsations, or vibrations in the rear end during braking, you may need to have your rotors "turned" (resurfaced) or just replace them with brand new rotors. If this is the first rear brake job on your SUV and the rotors appear to be in excellent condition, you should be able to just replace the pads with great results.

To remove the existing rotors and install new ones, remove the two 14mm bolts on the rear of the caliper bracket that attach it to the steering knuckle. Then loosen the old rotor with a rubber mallet, pull it off, and slide the new one in its place.

The 17mm front brake caliper bracket bolts torque specification is 48.7 lb-ft.

I recommend installing the Wagner ZD1114 QuickStop brake pads since they have excellent reviews on Amazon.

Orientate the wear indicator bar at the bottom of the inner brake pad.

Install the two new brake pads into the bracket.

Tighten Top Bolt
Line up the bolt holes in the caliper with their corresponding holes in the caliper slider pins within the bracket.

Spin in the two caliper bolts a few turns by hand in the counterclockwise direction (as seen from the outside of the SUV) to prevent them from becoming cross threaded.

Brake Fluid Bleeder Valve
Tighten the two caliper bolts by turning them in the counterclockwise direction (as seen from the outside of the car) with the 14mm socket and a 3/8" drive ratchet to just past hand tight or about 20 lb-ft of torque.

Double check that the two caliper bolts are tight before moving on to the next steps.

(The service manual specifies the rear brake torque values as follows: caliper 19.9 lb-ft, bracket, 48.7 lb-ft and bleeder valve 5.9 lb-ft.)

If your Forester's brake pedal has been feeling soft or spongy, the brake fluid may be contaminated with water or the brake lines may contain some air bubbles.

It would be best to bleed the brake lines at this time in order to flush out the old fluid and replace it with new DOT 3 brake fluid.

For more on this topic, please take a look at my Brake Line Fluid Bleeding With An Assistant DIY Guide or there is also my Brake Line Fluid Bleeding With A Power Bleeder Guide.

The brake fluid bleeder valve is located underneath a rubber cap on the back side of the caliper just below the top caliper bolt.

Slightly Tighten Lug Nuts
Carefully push the rear wheel over the lug studs.

Spin on the five lug nuts a few turns by hand in the clockwise direction to prevent them from becoming cross threaded.

Slightly tighten the lug nuts in a "criss cross" or "star" pattern with the lug nut wrench.

Torque 88 To 110 lb-ft

Carefully lower the car from the jack stands by using the floor jack.

Continue progressively tightening the lug nuts in a star or criss cross pattern to about 1/4 turn past hand tight.

It would be best to use a torque wrench or an electric impact wrench with a torque stick to properly tighten the lug nuts.

The owner's manual lists the lug nut torque specification as being a range between 88 lb-ft to 110 lb-ft.

Sit in the driver's seat of the vehicle and firmly push down the brake pedal a few times to restore the brake line pressure.

Check the brake fluid in the reservoir and verify that it is at the proper level. If it is low, pour in some fresh DOT 3 brake fluid from a new bottle.

To break in your new rear brake pads, just try to drive normally for the first few hundred miles while avoiding any hard or "panic" stops which may glaze over the new pads and cause them to become noisy and not perform as well.

It's also a good idea to regularly check your driveway, garage or parking spot for drops of fresh brake fluid which may indicate a leak, check the brake fluid level in the reservoir and also verify that the lug nuts are still tight.

Be sure to record the rear brake pad change in your SUV's service records.
