This automotive maintenance tutorial was specifically written to assist owners of the third generation (2015, 2016, 2017, 2018 and maybe also the updated 2019 and 2020 model years) Kia Sedona minivan in changing the rear disc brake pads and lubricating the caliper slider pins.

Owners of other Kia or Hyundai models such as the Grand Carnival, Sorento, Sportage, Niro, Soul, K900, Stinger, Cadenza, Optima, Rio, Forte, Genesis, Sonata, Ioniq, Santa Fe, Tucson, Elantra and Accent may also find these DIY instructions to be helpful.

A few compatible sets of new rear brake pads with their part numbers include the following: Wagner ZD1302, Raybestos SGD1284C, Kia 58302-A9A00, ACDelco 14D1284CH, Bosch BC1302, Beck Arnley 089-1800 and ProForce SMD1302.

The tools 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.

The first two steps are to park the minivan on a level surface and turn off the engine.

Engage the emergency parking brake and place wheel chocks on both sides of the front wheels to prevent the car from moving.

Slightly loosen the five lug nuts on the rear wheel by turning them about 1/4 to 1/2 turn in the counterclockwise direction.

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

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

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

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

Set the rear wheel aside in a safe place.

Loosen Upper Caliper Bolt
The rear brake caliper is held in place to the caliper bracket by two bolts located on the back side of the caliper.

The two caliper bolt heads face in towards the cargo area in the center of the vehicle.

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

Then loosen the top caliper bolt by turning it in the clockwise direction (as seen from the outside of the minivan) with the 14mm socket and the 3/8" drive ratchet.

Once the caliper bolts are loose, spin them out the rest of the way by hand.

Set the two caliper bolts aside in a safe place.

Carefully pull the caliper off the old pads and out of the bracket.

Remove "U" Clips

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

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

Gently remove the two "U" or "V" shaped metal spring clips off the rear edge of the old brake pads.

Set the two metal spring clips aside in a safe place for re-installation later on.

Remove Old Outer Pad
Pull the old inner and outer brake pads out of the bracket.

Make a mental note of where the wear indicator bar or "squeal" bar is located on the old brake pads.

On this 2015 Sedona LX, the wear indicator bar was situated at the bottom of the inner pad.

Don't discard the old pads just yet. We'll need one of them to help compress back the caliper piston.

Lubricate & Replace Pins
If your new set of rear brake pads included replacement brake hardware, pull the old pad abutment or "anti-rattle" clips out of the top and bottom of the bracket.

Apply a thin layer of brake parts lubricant to the new pad abutment clips where they will come in contact with the bracket and also the "ears" (ends) of the new brake pads.

Push the new pad abutment clips down into place at the top and bottom of the bracket.

In order for the brake caliper to operate smoothly, the two caliper pins need to be well lubricated.

Pull the caliper slider pins (also known as the "guide bolts") out of their rubber dust boots at the top and bottom of the bracket.

Spread a thin layer of brake parts lubricant on to the two caliper slider pins.

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

Compress Caliper Piston
In order for the caliper to fit over the thicker new brake pads, the caliper piston needs to be pushed back.

Attach the "F" clamp to the caliper and use an old brake pad to evenly distribute the pressure across the two pistons.

Move to the right rear area of the engine bay (closest to the driver's seat) and twist off the black plastic brake fluid reservoir cap in the counterclockwise direction.

Removing the reservoir cap will allow the brake fluid to more easily travel back through the system when you compress the caliper piston.

Set the reservoir cap aside in a safe place.

Slowly turn the "F" clamp handle in the clockwise direction to compress back the caliper piston.

Repeatedly check the brake fluid level in the reservoir while you are compressing the caliper piston to make sure it doesn't overflow.

Clean up any spilled brake fluid immediately since it can easily damage the vehicle's painted surfaces.

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

Continue compressing the caliper piston until it is flush with its rubber dust boot.

Detach the "F" clamp and discard the old brake pads.

Install New Outer Pad

Wear Bar - Bottom Inner Pad

Replace the reservoir cap as soon as possible. Brake fluid is hygroscopic which means it quickly absorbs moisture from the air leading to reduced braking performance.

Thoroughly clean off the brake rotor, caliper bracket, brake caliper assembly and the lug bolt holes with brake parts cleaner spray. Do not use compressed air or blow with your mouth to clean off the brake parts since inhaling brake dust can be harmful to your health. Brake dust could 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 Sedona has 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 new rotors. If this is the first rear brake job on your minivan and the rotors appear to be in excellent condition, you should be able to just replace the pads with great results.

The service manual's torque specification for the rear brake caliper bracket bolts is 47 to 54.2 lb-ft.

Install the new inner and outer brake pads into the caliper bracket.

The wear indicator bar should be situated at the bottom of the inner brake pad.

Push the two pads together until they are flush against the rotor.

Re-attach the two "U" shaped metal spring clips.

Carefully lower the caliper over the new brake pads and into the bracket.

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 minivan) to prevent them from becoming cross threaded.

Rubber Valve Cap
Tighten the two caliper bolts in the counterclockwise direction (as seen from the outside of the minivan) with the 14mm socket and a 3/8" drive ratchet to just past hand tight.

The service manual specifies that the rear caliper bolts should be tightened to 15.9 to 23.1 lb-ft of torque.

If your brake pedal has been feeling soft or spongy, the brake fluid might 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 to remove the air bubbles and replace it with fresh DOT 3 or DOT 4 brake fluid. For more on this topic, check out my Brake Line Fluid Bleeding With An Assistant DIY Guide or alternatively the Brake Line Fluid Bleeding With A Power Bleeder Guide.

The brake fluid bleeder valve is located just below the top caliper bolt and is covered by a rubber cap.

Torque Lug Nuts
Slightly tighten the 5 lug nuts in a "star" or "criss cross" pattern with the tire iron.

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

Continue tightening the lug nuts in a "star" 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 and tighten the lug nuts to the service manual specification of between 65.1 to 79.6 lb-ft of torque.

Double check that the lug nuts are tight before driving.

Sit in the driver's seat of the vehicle and firmly pump 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, add some fresh DOT 4 fluid.

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

It's also a good idea to regularly check your driveway for drops of 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 brake pad change in your vehicle's service records.
