This automotive maintenance tutorial was specifically written to assist owners of the second generation (2010, 2011, 2012, 2013, 2014 & 2015) Kia Sorento SUV in changing the rear disc brake pads and lubricating the caliper slider pins.

Owners of other Kia and Hyundai vehicles such as the Optima, Forte, Cadenza, K900, Rio, Sportage, Sedona, Soul, Elantra, Veloster, Sonata, Azera, Tucson, Santa Fe, Genesis and Equus may also find these DIY instructions to be helpful.

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 ratcheting wrench, a "C" clamp and a tube of synthetic brake parts lubricant grease.

A few compatible sets of new rear brake pads with their part numbers include the following: Wagner QuickStop ZD1284, Wagner ThermoQuiet QC1284, Bendix D1284 CQ, Prime Choice PCD1284, Power Stop 16-1284, Monroe CX1284, Akebono ACT1284, Bosch BP1284, Dura International BP1284MS and Centric # 301.12840.


Please verify the correct replacement part number for your Sorento by consulting your dealership's parts counter, calling an automotive parts store or by using the Amazon Part Finder website before buying new brake pads.

The correct part numbers may vary depending on your SUV's model year and depending on whether it is equipped with a 2WD (two wheel drive) or AWD (all wheel drive) transmission system.

Caliper, Bracket, Rotor
The first few steps are to park the vehicle on a level surface, make sure that the emergency / parking brake is not engaged, and chock both sides of the front wheels to prevent the SUV from moving.

Then slightly loosen the five lug nuts on the rear wheel by turning them counterclockwise with the tire iron.

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

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

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

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

Loosen the upper caliper bolt by turning it clockwise (as seen from the outside of the vehicle) with the 14mm socket and ratcheting wrench.

Then loosen the other 14mm bolt at the bottom of the caliper by turning it clockwise (again, as seen from the outside of the vehicle).

Remove Old Outer Pad
Pull the rear brake caliper out of the bracket and off the old pads.

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

Pull the old inner and outer brake pads out of the bracket.

Pull Out Caliper Slider Pin
Make a note of where the wear indicator or "squeal" bar is located on the old brake pads.

On this 2014 Sorento model, the wear bar was situated at the bottom of the inner brake pad.

I recommend buying the Wagner ThermoQuiet QC1284 brake pads since they have excellent reviews on Amazon.

If your new set of rear brake pads included a bag of replacement brake hardware, pull the old metal pad abutment or "anti-rattle" clips out of the top and bottom of the bracket and install the new ones in their place.

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

Pull the caliper slider pins out of their rubber dust boots, apply a thin layer of brake caliper grease to each before pushing them back in to their dust boots.

Attach "C" Clamp To Piston

Remove Brake Fluid Cap
In order for the caliper to fit over the thicker new brake pads, the caliper piston needs to be compressed back.

Attach the "C" clamp to the caliper using the back of an old brake pad to evenly distribute the pressure across the piston.

Move to the right rear area of the engine bay (close to the driver's seat) and twist off the brake fluid reservoir cap in the counterclockwise direction. Set the plastic cap aside in a safe place.

Slowly turn the "C" clamp's handle in the clockwise direction to push back the piston while repeatedly checking the level in the brake fluid reservoir to make sure it doesn't overflow.

Clean up any spilled brake fluid immediately with a towel and rinse the area with plenty of water. Brake fluid can easily damage painted surfaces.

Install New Outer Pad
Continue compressing the caliper piston until it is flush with its rubber dust boot. Try to avoid pinching or otherwise damaging the rubber dust boot around the piston.

Replace the brake fluid reservoir cap as soon as possible since brake fluid is hygroscopic (readily absorbs moisture from the air).

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

 If your Sorento previously exhibited shuddering, pulsating, or vibrations in the front end during braking, you may need to have your rotors "turned" (resurfaced) or it may be easier and less expensive to just replace them with new rotors. If this is the SUV's first front brake job and the rotors appear to be in good condition, you should be able to just change the pads with excellent results.

To remove the existing rotors and install new ones, remove the two bolts on the rear of the caliper bracket that attach it to the steering knuckle. Then remove the two Phillips head set screws before loosening the old rotor with a rubber mallet. Pull it off, and slide the new one in its place.

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

Lower Caliper Over Pads

Install the new brake pads in to the caliper bracket with the wear indicator bar situated at the bottom of the inner brake pad.

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

Carefully lower the caliper down over the new brake pads and in to the bracket.

If the caliper won't fit over the new pads, you may need to compress the piston back a bit further.

Tighten Counterclockwise

Line up the bolt holes in the caliper with their corresponding bolt holes in the slider pins installed within the bracket.

Re-insert the two caliper bolts and spin them in a few turns by hand in the clockwise direction (as seen from the outside of the vehicle) to prevent the bolts from becoming cross threaded.

Tighten the upper and lower caliper bolts by turning them counterclockwise with the 14mm socket and 3/8" drive ratcheting wrench to just past hand tight or about 20-25 lb-ft of torque.

Brake Fluid Bleeder Valve

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

If your brake pedal previously felt 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 fresh DOT 3 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 underneath a rubber cap on the back side of the caliper just below the upper caliper bolt.

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

Carefully lower the SUV from the two jack stands using the floor jack.

Continue progressively tightening the five lug nuts in a "criss cross" or "star" pattern to about 1/8 to 1/4 turn past hand tight or about 65 to 80 lb-ft of torque.

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

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, pour in some fresh DOT 3 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 may glaze over the new pads and cause them to be noisy and/or not perform as well.

It's also a good idea to regularly check your driveway or garage floor 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.
