Tucson Rear Brake Pads Replacement Guide
How to change the rear disc brake pads on
a third generation 2016, 2017 and 2018 Hyundai Tucson SUV.
2018 Tucson Rear Wheel |
Slightly Loosen Lug Nuts |
Raise Rear of SUV |
This
automotive maintenance tutorial was specifically written to assist
owners of the third generation (2016, 2017, 2018 plus the updated
2019 and 2020 model years) Hyundai Tucson SUV in changing the rear
disc brake pads and lubricating the caliper slider pins. Owners of other Hyundai, Kia and Genesis vehicles such as the Santa Fe, Kona, Elantra, Sonata, Accent, Veloster, Ioniq, Nexo, G80, G90, Stinger, Rio, Forte, Optima, Cadenza, K900, Soul, Niro, Sportage, Sorento and Sedona 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: Bendix CFC1848, Power Stop Z23-1848, AM Autoparts AM-2481850838, StopTech 305.11570, ProForce CRD1398 and TRQ BFA78679. 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. |

Spin Off Five Lug Nuts |
Five Lug Nuts Removed |
Caliper, Bracket, Rotor |
The first few steps
are to park the SUV on a level surface, place the transmission in "Park" and
turn off the ignition. Make sure that the emergency / parking brake is NOT engaged. If the parking brake is engaged, you won't be able to pull the rear 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 while you are replacing the pads. Slightly loosen the five lug nuts on the rear wheel by turning them about 1/4 to 1/2 turn in the counterclockwise direction with the tire iron. Carefully raise the rear of the SUV with the floor jack and securely support it with at least two jack stands. I prefer to only work on one side of the vehicle to keep three tires on the ground for extra safety. Spin off the five lug nuts and set them aside in a safe place. Carefully remove the rear wheel and set it aside. Some people like to place the wheel and tire under the frame rail of the SUV as another safety measure just in case the jack stands and floor jack fail. Once the wheel has been removed, you'll be able to see the rear caliper, bracket, rotor and suspension. |

Rear Brake Caliper |
Loosen Lower Bolt |
Spin Out Caliper Bolt |
The rear brake
caliper is held in place to the bracket by two bolts on the back side of the
caliper with the bolt heads facing in towards the cargo area of the SUV. Loosen the lower 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 upper caliper bolt by turning it in the clockwise direction (as seen from the outside of the car) with the 14mm socket and a 3/8" drive ratchet. |
||
Remove Lower Caliper Bolt |
Two Caliper Bolts Removed |
Pull Caliper Off Pads |
Spin out the two
caliper bolts by hand and set them aside in a safe place. Carefully pull the caliper off the old pads and out of the bracket. |
||
Rest Caliper On Rotor |
Two "V" Spring Clips |
Remove Spring Clips |
Avoid stressing,
kinking, bending or pulling on the rubber brake fluid hose. Rest the caliper on the rotor or suspend it from the suspension spring with a bungee cord or some twine. Pull the two "V" shaped metal spring clips off the rear edge of the old brake pads. Your new set of rear brake pads may include new "V" spring clips. If not, save the old ones for re-installation later. |
||
Pull Off Lower Clip |
Push In Metal Tab |
Remove Outer Pad |
I found it
difficult to pull the old brake pads out of the bracket due to the metal
tabs on the pad abutment clips. If necessary, gently push in the metal tabs with a flathead screwdriver to release the old brake pads from the bracket. |
||
Push In Metal Tab |
Wear Bar - Bottom Inner Pad |
Replace Pad Abutment Clip |
Pull the old 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 2018 Tucson, the wear indicator bar was situated at the bottom of the inner brake pad. If your new set of rear brake pads includes replacement brake hardware, pull the old pad abutment clips or "anti-rattle" clips out of the top and bottom of the bracket. |
||
|
||
Replace Top Abutment Clip |
Pull Out Caliper Slider Pins |
Lubricate & Replace Pins |
Apply a thin layer
of brake parts lubricant grease to the top and bottom of the new pad
abutment clips. Clean off the rotor, caliper, lug studs and bracket with brake parts cleaner spray. Push the new pad abutment clips into the top and bottom of the bracket. Make sure they are fully seated. In order for the caliper to operate smoothly, the two caliper slider pins need to be well lubricated. Pull the caliper slider pins out of their rubber dust boots attached to the bracket. Apply a thin layer of brake caliper grease to the smooth parts of the caliper slider pins. Push the caliper slider pins back into the bracket. |
||
Attach "F" Clamp To Caliper |
Twist Off Reservoir Cap |
Compress Caliper Piston |
In order for the
caliper to fit over the thicker new brake pads, the caliper piston will need
to be compressed or "retracted" back into the caliper. Attach the "F" clamp to the caliper and use 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 windshield and the driver's seat) and twist off the round black plastic brake fluid reservoir cap in the counterclockwise direction. Removing the reservoir cap will allow the brake fluid to easily move back through the system when you compress the caliper pistons. Slowly turn the "F" clamp handle in the clockwise direction to compress back the caliper piston. Try to avoid pinching or otherwise damaging the rubber dust boot that surrounds the caliper piston. Continue compressing the caliper piston until it is just about flush with the rubber dust boot. |
||
Replace Reservoir Cap |
Install New Outer Pad |
Wear Bar - Bottom Inner Pad |
Replace the
reservoir cap as soon as possible. Brake fluid is hygroscopic (absorbs
moisture from the air) so don't leave the reservoir cap off for any longer
than necessary. If your Tucson 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 Phillips head set screws in the counterclockwise direction, remove the two large 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. Install the two new brake pads into the bracket. If you have a torque wrench, the specification in the service manual for the rear brake caliper bracket bolts is 47.0 to 54.2 lb-ft of torque. The wear indicator bar should be at the bottom of the inner brake pad. |
||
Push Pads Together |
Lower Caliper Over Pads |
Spin In Bottom Bolt |
Push the two pads
together until they are flush against the rotor. (Note - I forgot to replace the "V" shaped metal spring clips in the pictures.) If your new pads are equipped with the small holes on the rear edge of the pads, install the new "V" spring clips or re-use the old ones. Carefully lower the caliper over the new 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 vehicle) to prevent them from becoming cross threaded. |
||
Spin In Top Bolt |
Tighten Top Bolt |
Tighten Bottom Bolt |
Tighten the two caliper bolts in the counterclockwise direction with the
14mm socket and a 3/8" drive ratchet to just past hand tight or about
20 lb-ft
of torque. The torque specification in the service manual for the 14mm rear caliper bolts is 15.9 to 23.1 lb-ft (21.6 to 31.4 N*m). Double check that the two caliper bolts are tight before moving on to the next steps. |
||
Rubber Valve Cap |
Brake Fluid Bleeder Valve |
Push On Rear Wheel |
If your brake pedal previously felt 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 and replace it with fresh DOT 3 brake fluid or you can also use 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 underneath a rubber cap on the back side of the caliper just below the upper caliper bolt. |
||
Spin On Five Lug Nuts |
Slightly Tighten Clockwise |
|
Carefully push the rear wheel back over the lug studs and 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 "star" or "criss cross" pattern with the lug nut wrench. |
||
Lower Car From Stands |
Tighten Lug Nuts |
Rear Brake Pads Changed |
Carefully lower the rear of the SUV from the jack stands by using the floor jack. Continue progressively tightening the 5 lug nuts in a "criss cross" or "star" pattern to about 1/8 to 1/4 turn past hand tight or about 65 to 79 ft-lbs of torque. It would be best to use a torque wrench or an electric impact wrench with an 80lb-ft torque stick to properly tighten the lug nuts. Sit in the driver's seat of the vehicle and firmly press 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 or 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 may 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 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.
