🔧 Optima - Front Brake Pads & Rotor Replacement
Replacing the front pads and rotors means removing the caliper, removing the caliper bracket, swapping the rotor, then reinstalling everything with the correct hardware and torque. On your Optima, there are a couple front brake size variants, and the bolt sizes/torque specs depend on which one you have.
Difficulty Level: Intermediate | Estimated Time: 2-4 hours
⚠️ Safety & Precautions
- 🛑 Support the car with jack stands; never rely on a jack.
- 🧤 Wear gloves and safety glasses; brake dust and rust fall easily.
- 🔥 Brakes can be hot; let the front brakes cool before starting.
- 🧪 Do not let brake fluid overflow when compressing the caliper piston; check the reservoir level often.
- 🪝 Do not hang the caliper by the hose; support it with a hanger.

🔨 Step-by-Step Instructions
Follow these steps in order:
Before I give you the exact bolt sizes and Kia torque specs, answer these 2 quick questions:
- 1) What front wheel size do you have: 17" or 18"?
- 2) Can you measure your front rotor diameter (edge-to-edge): about 300 mm (11.8") or about 320 mm (12.6")?
Once you reply, I’ll give you the full, torque-correct step-by-step for your exact front brake setup (including lug nut torque, caliper bolts, bracket bolts, and rotor retention screw info if equipped).
✅ After Repair
- With the engine off, pump the brake pedal until it feels firm before moving the car.
- Check the brake fluid level and top off only if needed (use the correct DOT fluid listed on the cap).
- Do a slow test drive and confirm no pulling, grinding, or pulsation.
