This procedure replaces the front brake pads and rotors on a 2015 Kia Forte 1.8L, including caliper service and proper torque specifications for safe brake system operation.

Warnings

Tools required

Parts

• Front brake pad set (includes 4 pads) × 1 — Use OEM specification or equivalent
• Front brake rotors × 2 — Use OEM specification or equivalent
• Brake pad anti-squeal shims (if not included with pads) × 1 — Use OEM specification
• Brake hardware kit (clips, springs) × 1 — Use OEM specification

Fluids

• DOT 4 Brake Fluid — 0.5 qt

Preparation

1. Park vehicle on firm, level surface and engage parking brake.
2. Place wheel chocks behind rear wheels.
3. Open brake fluid reservoir cap and remove approximately 1/4 of fluid using turkey baster to prevent overflow when compressing pistons. Properly dispose of old fluid.
4. Loosen front wheel lug nuts 1/4 turn while vehicle is on ground.
5. Raise front of vehicle with floor jack at manufacturer's designated jacking point and support with jack stands under the front subframe.
6. Remove front wheels completely and set aside.
7. Inspect brake lines, hoses, and calipers for any signs of leakage or damage before proceeding.

Procedure

1. 1

   Remove caliper slide bolts
   Locate the two caliper slide bolts on the rear of the caliper assembly (accessible from behind the caliper). Using a 17mm socket, remove both slide bolts completely. These are the smaller bolts that hold the caliper to the bracket. Keep bolts in a clean area for inspection.
2. 2

   Remove caliper and support
   Carefully pivot the caliper upward and away from the rotor. Do NOT let the caliper hang by the brake hose. Use wire or a bungee cord to securely hang the caliper from the suspension strut or other solid component. Inspect the brake hose for cracks or damage.
   ⚠Never allow the caliper to hang by the brake hose as this can damage the hose internally and cause brake failure.
3. 3

   Remove old brake pads and hardware
   Remove the inner and outer brake pads from the caliper bracket. Note the orientation and position of any anti-rattle clips or shims. Remove the pad retaining clips from the bracket. Inspect all hardware for wear, rust, or damage. Replace hardware kit even if old hardware appears serviceable.
4. 4

   Remove caliper bracket
   Locate the two large caliper bracket bolts securing the bracket to the steering knuckle (these are larger than the slide bolts). Using a 19mm socket, remove both bracket bolts completely. Remove the caliper bracket from the knuckle. These bolts may be very tight and require significant force to loosen.
5. 5

   Remove old rotor
   Remove the old brake rotor from the wheel hub. The rotor may be held by a small Phillips screw or may be held on by corrosion. If stuck, tap gently with a rubber mallet from behind or use penetrating oil. Do NOT hit the rotor face. Clean the hub surface with a wire brush to remove all rust and corrosion.
6. 6

   Install new rotor
   Clean both sides of the new rotor thoroughly with brake cleaner to remove any protective coating or oil. Wipe completely dry. Place the new rotor onto the hub, ensuring it sits flat against the hub surface. If present, reinstall the rotor retaining screw finger-tight (this screw is only for assembly and is not torque-critical).
7. 7

   Reinstall caliper bracket
   Apply medium-strength thread locker to the threads of both caliper bracket bolts. Position the caliper bracket over the new rotor and align with the mounting holes on the knuckle. Thread both bracket bolts by hand first to ensure proper threading. Torque both bracket bolts to specification in an alternating pattern.
   ⚠️Caliper bracket bolts are CRITICAL safety fasteners. Incorrect torque can result in caliper detachment and complete brake failure.

   Caliper Bracket Bolts97 Nm (71 lb-ft)
8. 8

   Install new brake pad hardware
   Clean the caliper bracket pad contact points with a wire brush and brake cleaner. Install the new pad retaining clips onto the caliper bracket, ensuring they snap firmly into place. Apply a thin layer of high-temperature silicone brake grease to the pad contact points on the bracket (where pads slide) and to the outer edges of the pad backing plates. Do NOT get grease on the friction material or rotor surface.
9. 9

   Compress caliper piston
   Before installing pads, the caliper piston must be compressed fully into its bore. Use a C-clamp or brake caliper piston tool, placing one side against the back of the caliper body and the other against the piston face (or use an old brake pad as a spreader). Slowly compress the piston completely. Watch the brake fluid reservoir to ensure it does not overflow. If it begins to overflow, remove more fluid.
10. 10

    Install new brake pads
    Install the new inner and outer brake pads into the caliper bracket, ensuring they are properly seated in the retaining clips. Verify that any anti-squeal shims are correctly positioned as per the pad manufacturer's instructions. The pads should move slightly but be held firmly by the clips.
11. 11

    Reinstall caliper
    Remove the caliper from its support wire. Clean the caliper slide bolts and inspect the rubber boots on the slide pins for tears or damage. Apply a thin coat of high-temperature silicone brake grease to the smooth portion of each slide bolt (not the threads). Position the caliper over the pads and bracket, aligning the slide bolt holes. Thread both slide bolts by hand to prevent cross-threading.
12. 12

    Torque caliper slide bolts
    Using a torque wrench, tighten the caliper slide bolts to specification. Verify that the caliper is properly seated on the bracket and that the pads are correctly positioned on both sides of the rotor.
    ⚠️Slide bolts must be torqued correctly. Under-torquing can allow caliper movement and brake failure; over-torquing can damage threads or seize the slide mechanism.

    Repeat for opposite side
    Repeat all steps (1 through 12) on the opposite front wheel to replace the second set of pads and rotor. Brake components should always be replaced in axle sets to maintain balanced braking performance.
14. 14

    Reinstall wheels
    Clean the wheel mounting surface on the hub with a wire brush. Mount the front wheels and thread all lug nuts by hand. Lower the vehicle until the tires just touch the ground (still supported mostly by jack stands). Torque the lug nuts to specification in a star pattern.

15. 15

    Final brake system preparation
    Fully lower the vehicle and remove jack stands. Before starting the engine, pump the brake pedal slowly 10-15 times until it feels firm. This repositions the caliper pistons against the new pads. Check brake fluid level in the reservoir and top off with fresh DOT 4 brake fluid to the MAX line if needed. Replace the reservoir cap securely.
    ⚠️DO NOT attempt to drive the vehicle until the brake pedal feels firm and returns to normal height. If pedal remains soft after pumping, there may be air in the system or a component was not installed correctly.

Reassembly

1. Ensure all tools and parts are removed from the wheel wells and undercarriage.
2. Double-check that all lug nuts are torqued to specification.
3. Verify the brake fluid reservoir is at the proper level and cap is secure.
4. Wipe any brake fluid drips or fingerprints from painted surfaces immediately.

Verification

• With engine running, pump brakes several times and verify pedal feels firm and holds steady pressure.
• Perform a slow-speed brake test in a safe area (driveway or empty parking lot) to verify brakes engage smoothly without pulling to one side.
• Check for any unusual noises, vibrations, or fluid leaks around all work areas.
• Perform proper break-in procedure: Make 10-15 gradual stops from 30 mph with 30-60 seconds between stops to allow rotors to cool. Avoid hard braking for the first 200 miles.
• After initial test drive (50-100 miles), re-torque all lug nuts to specification as wheels may settle.
• Monitor brake fluid level for the first few days; a slight drop is normal as pads wear into rotors, but significant loss indicates a leak.
• If brake warning light illuminates, pedal feels spongy, or vehicle pulls to one side when braking, STOP driving immediately and seek professional inspection.
