2018-2023 Kia Stinger Brake Job Tools and Torque Specs

By Core Brake Parts Tech Team — Circleville, OH warehouse

A Kia Stinger brake job needs ordinary hand tools plus three things people forget: a torque wrench that covers the factory lug nut range of 79 to 94 lb-ft, a way to put the electronic parking brake out of the way before you touch the rear pistons, and the right fluid, which Kia lists as DOT-4LV. What else you need depends on which brakes your car has. V6 twin-turbo GT trims carry Brembo fixed calipers, while four-cylinder cars use smaller single-piston sliding calipers and smaller rotors.

Which Stinger Brakes Do You Have?

The Stinger was sold from the 2018 model year and production ended after 2023, and two brake packages ran through the whole run. Kia's own brochure says the V6 twin-turbo GT trims use Brembo brakes with fixed quad-piston front calipers and dual-piston rear calipers behind 19-inch wheels. Everything else uses a conventional sliding-caliper setup. Identify yours before you order parts, because rotors and pads do not interchange between the two.

The quickest check is to look through the wheel. Red calipers with the Brembo name cast or printed on them mean the GT package. A plain caliper body on slide pins means the base system. Brembo's replacement catalog lists these rotor sizes for the Stinger:

The minimum thickness is the number that matters on the day. Measure each rotor with a micrometer at several points around the face. If any reading is at or below the minimum, the rotor is scrap and gets replaced, not resurfaced.

Tools for the Job

Nothing on a Stinger brake job needs special equipment except the parking brake step. Lay this out before you start:

• Floor jack and jack stands. Never work under a car held up only by a jack. Use the lift points shown in the owner's manual.
• Torque wrench that covers the 79 to 94 lb-ft lug nut range, plus a lower-range wrench for caliper and bracket hardware.
• Metric sockets and wrenches, including a breaker bar for caliper bracket bolts, which are usually tight.
• Brake piston tool. A wide C-clamp or spreader works on the single-piston base calipers. On the Brembo fixed calipers, push the opposed pistons back evenly with a flat pad spreader so none of them cocks in its bore.
• Scan tool with electronic parking brake service function, or the release steps in the factory service information, for rear work.
• Micrometer to check rotor thickness against the table above.
• Wire brush, brake cleaner and high-temperature brake lubricant for the hub face, pad abutments and slide pins.
• Clear bleeder hose, catch bottle and a sealed bottle of DOT-4LV fluid if you open the hydraulic system or flush it.
• Wire or a bungee strap to hang the caliper. Never let a caliper hang from its rubber hose.

Torque Specs: What Kia Publishes and What to Look Up

The Stinger owner's manual gives wheel lug nut torque as 11 to 13 kgf-m, which is 79 to 94 lb-ft or 107 to 127 N-m, for every factory wheel and tire size. Tighten the nuts in a star pattern, in two passes, with the wheel on the ground. Running lug nuts on with an impact gun is a common cause of a pulsing pedal after a brake job, because uneven clamping distorts the rotor hat against the hub.

Caliper guide pin bolts, caliper bracket bolts and the Brembo caliper mounting bolts all have their own values, and they differ between the base and Brembo systems. Kia does not print them in the owner's manual. Torque them to the values in the factory service manual for your exact trim, and do not borrow a number from another car on the same platform. If a bracket bolt uses thread locker from the factory, clean the threads and apply fresh locker as the service information directs.

Other values worth knowing from the owner's manual: the brake system holds about 0.42 US quart (0.395 L) of fluid, and Kia specifies fluid meeting SAE J1704 DOT-4LV, ISO 4925 Class 6, FMVSS 116 DOT-4. DOT-4LV is a low-viscosity DOT 4 that flows better through the ABS and stability-control valves when cold. Do not top up with DOT 3, and never with DOT 5 silicone fluid.

Front Brakes, Step by Step

1. Loosen the lug nuts slightly, raise the car, set it on stands and remove the wheel.
2. On base calipers, remove the guide pin bolts, swing or lift the caliper off and hang it. Pull the pads and abutment clips from the bracket. On fixed Brembo calipers, the pads typically come out after removing the pad retaining pins and anti-rattle spring, and the caliper only has to come off if you are replacing the rotor.
3. For a rotor change, remove the caliper bracket bolts (base) or caliper mounting bolts (Brembo), then the rotor. Clean rust off the hub face with a wire brush so the new rotor sits flat.
4. Fit the new rotor, reinstall the bracket or caliper and torque those bolts to the service manual value.
5. Push the piston or pistons back slowly while watching the reservoir so it does not overflow. Clean and lightly lubricate abutments and slide pins, fit new clips, and install the pads.
6. Reinstall the wheel, lower the car and torque the lug nuts to 79 to 94 lb-ft.

Front parts for the GT include DBA 4000 Series T3 slotted front rotors for Brembo-equipped Stingers and EBC Redstuff ceramic front pads for the 3.3L twin turbo. Base-brake owners should look at the 320 mm DBA T3 front rotor, which matches the base system size above.

Rear Brakes and the Electronic Parking Brake

Every Stinger has an electronic parking brake, and the owner's manual says it can apply itself, for example when Auto Hold is on and the engine is switched off. That is the part of the job that can hurt you or the caliper. Before you remove rear pads, switch Auto Hold off, release the parking brake with the car in Park, and then put the system in its service or maintenance position with a scan tool or the factory procedure, so the actuator is retracted and cannot clamp while your hands are in the caliper. Forcing a rear piston back against an engaged actuator can strip the actuator gears.

Once the parking brake is retracted, the rear job follows the same pattern as the front. When you are done, exit service mode, pump the pedal until it is firm, and cycle the parking brake switch a few times so the system relearns pad position. A brake or EPB warning light that stays on means the procedure did not complete. The manual says to have the system checked if the EPB warning does not clear.

Rear parts include EBC Redstuff ceramic rear pads and the DBA T3 slotted rear rotor for the 3.3L V6 GT. You can also browse all brake pads and brake rotors, plus brake hardware kits for new clips and pins.

What to Replace Together, and Bedding In

Replace pads in axle sets, both sides at once. Replace rotors whenever they are under minimum thickness, deeply grooved or have a lip you can catch a fingernail on. New pads on worn rotors bed poorly and often squeal. Replace abutment clips when they are rusted or have lost their spring, and inspect the flexible hoses for cracking or bulging while the wheels are off.

Bed the new pads before normal driving: a series of moderate stops from medium speed without coming to a full stop, then a cool-down drive with no hard braking. Follow the pad maker's own bedding procedure where it gives one. Kia's manual also notes that the brakes can make noise in some weather and after driving on de-iced roads, and that riding the pedal causes excessive pad wear, so a little squeal on a cold wet morning is not by itself a defect.

One safety note for 3.3L twin-turbo owners: NHTSA recall 20V-518 (Kia campaign SC196) covers an engine compartment fire risk near the ABS hydraulic electronic control unit on certain Stinger 3.3L T-GDI cars. It is not a pad or rotor issue, but check your VIN on NHTSA's recall site and have the remedy done at a Kia dealer before you start on the brakes.

Frequently Asked Questions

What is the lug nut torque on a Kia Stinger?

Kia's owner's manual specifies 11 to 13 kgf-m, which is 79 to 94 lb-ft (107 to 127 N-m), for all factory wheel sizes. Tighten in a star pattern with a torque wrench and recheck after the first short drive.

Do I need a scan tool to change Stinger rear brake pads?

You need a way to put the electronic parking brake in its service position, either a scan tool with that function or the release procedure in the factory service information. Do not force the rear pistons back against an engaged parking brake actuator.

What brake fluid does the Kia Stinger use?

The owner's manual specifies fluid meeting SAE J1704 DOT-4LV, ISO 4925 Class 6 and FMVSS 116 DOT-4. Use a fresh, sealed bottle, since brake fluid absorbs moisture once opened.

Are Brembo and non-Brembo Stinger rotors the same?

No. Brembo-equipped GT cars use a 350 mm front and 340 mm vented rear rotor, while base cars use a 320 mm front and 314 mm solid rear rotor. Pads differ too, so confirm which calipers you have before ordering.

Can I resurface Stinger rotors instead of replacing them?

Only if they will still be above minimum thickness after machining. On the Brembo front rotor that minimum is 28 mm from a new thickness of 30 mm, so there is very little material to remove. Most of the time replacement is the better choice.
