How to Replace Brake Pads on a Kia K5

By Core Brake Parts Tech Team — Circleville, OH warehouse

Yes, a home mechanic can replace the brake pads on a Kia K5. Plan on one to two hours per axle with a floor jack, jack stands, a socket set, a caliper piston tool, and a torque wrench. The front axle is a straightforward floating-caliper job; the rear axle on some model years adds an electronic parking brake that has to be put into service mode before the piston will move, so read the rear section before you start.

What Makes the Kia K5 Brake Job Different

The front calipers on the K5 are conventional single-piston floating calipers that slide on two greased pins. Pull the slide bolts, lift the caliper off, swap the pads, and press the piston back. Nothing exotic.

The rear axle is where owners get stuck. Depending on the model year, the K5 uses an electronic parking brake (EPB). The parking-brake motor lives on the back of the rear caliper and holds the piston out. If you clamp that piston without retracting the motor first, you can damage the actuator and you will not get the pads in. Some rear pistons also have to be rotated inward with a cube tool rather than pushed straight in. Confirm which setup your car has by looking at the rear caliper: a motor housing with an electrical connector means EPB.

Tools and Parts You Need

• Floor jack and a pair of jack stands rated for the car
• Lug wrench or breaker bar with the correct socket
• Metric socket set and ratchet for the caliper slide bolts
• C-clamp or caliper piston press for the fronts
• Caliper cube tool for rear pistons that rotate in
• Scan tool or the vehicle's EPB service-mode procedure for rear pads on EPB-equipped cars
• Brake cleaner and a wire brush
• High-temperature silicone caliper grease
• Torque wrench that covers the caliper-bolt and lug-nut range
• Wire hook or bungee to hang the caliper
• New brake pads for your K5 in a matched axle set
• A fresh brake hardware kit with abutment clips and pin boots

Buy pads and hardware together. The stainless abutment clips that came with the car are rusted and fatigued by the time the pads wear out, and new pads on old clips is the most common reason a fresh brake job squeals.

Step-by-Step: Front Brake Pads on a Kia K5

1. Park on level concrete, set the parking brake, and chock the rear wheels. Crack the front lug nuts loose about a quarter turn while the tire is still on the ground.
2. Lift the front of the car with the floor jack at the factory lift point and set a jack stand under the pinch weld or subframe. Lower the car onto the stand. Never work under a vehicle held only by a jack.
3. Remove the lug nuts and pull the wheel.
4. Open the hood and remove the brake-fluid reservoir cap. Check the level; if the reservoir is near full, siphon a little out so it does not overflow when you push the pistons back.
5. Remove the two caliper slide bolts from the back of the caliper. Lift the caliper off the bracket and hang it from the strut spring with a hook. Do not let it dangle by the brake hose.
6. Pull the old pads out of the bracket and pry off the old abutment clips.
7. Inspect the rotor. Deep grooves, a pronounced lip at the outer edge, or blue heat spots mean the rotor needs to go. Measure thickness with a micrometer and compare it to the minimum stamped on the rotor hat. Anything at or below minimum gets replaced now, not later.
8. Use the C-clamp against the old inner pad to press the piston fully back into the caliper. Watch the reservoir so it does not overflow.
9. Pull the slide pins out of the bracket, wipe off the old grease, and check the rubber boots for tears. Clean the pad-contact lands on the bracket with a wire brush and brake cleaner.
10. Fit the new abutment clips, put a thin film of silicone grease on the clip surfaces where the pad ears ride, and re-grease the slide pins before sliding them home.
11. Install the new pads. Confirm any wear-indicator tab is positioned as the old set was.
12. Set the caliper back over the pads, thread the slide bolts in by hand, then torque them to the value in the K5 service manual. If the manual calls for thread locker on the caliper bolts, use it.
13. Reinstall the wheel, snug the lug nuts, lower the car, and torque the lugs in a star pattern to the manual spec.
14. Repeat on the other side. Pads are always replaced in axle sets.

Rear Brake Pads: Electronic Parking Brake Steps

1. Before lifting the car, put the EPB into service mode using the vehicle's procedure or a scan tool that supports the function. This retracts the parking-brake motor so the piston is free.
2. Lift and support the rear of the car, then remove the wheel and caliper the same way as the front.
3. If your rear piston has notches in its face, it must be rotated in with a cube tool while applying light pressure. Pressing it straight in with a C-clamp will strip the internal mechanism.
4. Replace clips, grease pins, fit pads, and torque the caliper bolts per the manual.
5. After both rear wheels are back on and torqued, take the EPB out of service mode and cycle the parking brake a few times so the motors re-seat the pads.

Safety Rules That Are Not Optional

• Jack stands under the car every single time. A jack is a lifting tool, not a support.
• Wear safety glasses when using brake cleaner and when clipping the old hardware off.
• Keep brake grease off the pad friction faces and the rotor surface.
• Pump the brake pedal until it is firm before you start the engine and before the car moves. The first pedal stroke after a pad change is nearly to the floor while the pistons travel back out.
• Top the reservoir back up only after the pistons are pressed in and the pedal is firm.

Bedding In the New Pads

Fresh pads need a transfer layer on the rotor before they stop at full strength. Follow the pad maker's bedding procedure, which typically means a series of moderate stops from moderate speed without coming to a complete halt, followed by a cool-down drive. Skip this and you invite glazing, judder, and noise.

When to Call a Shop

Stop and get help if the rear EPB refuses to enter service mode, if a slide pin is seized in the bracket and will not turn, if a caliper bolt breaks, or if the rotor is below minimum and you did not plan on replacing it. A pedal that stays spongy after pumping means air or a fluid leak, and that needs a proper bleed before the car is driven.

Frequently Asked Questions

Do I need a scan tool to change rear pads on a Kia K5?

On model years with an electronic parking brake, yes, or you need the manufacturer's procedure for putting the EPB into maintenance mode. Without retracting the motor, the rear piston will not compress and forcing it can break the actuator.

Should I replace the rotors at the same time?

Replace them if they measure at or below the minimum thickness, are grooved, or show heat spots. If they are within spec and smooth, new pads on the existing rotors is acceptable.

What torque should I use on the caliper bolts?

Use the value in the K5 factory service manual for your model year. Guessing torque on caliper hardware is how bolts back out or snap.

Why do my new pads squeak?

Usually old abutment clips, dry slide pins, or skipping the bed-in procedure. Fresh hardware and proper grease on the contact points solves most of it.
