How to Replace Front Brake Pads & Rotors
⚠️ Critical Safety Warning
Brakes are a safety-critical system. Never drive on partially installed components. Always work on a level surface with proper jack stands. If you're unsure at any point, consult a professional.

Step-by-Step Procedure
Park on a flat, solid surface. Engage the parking brake and place wheel chocks behind the rear tires. Loosen lug nuts slightly while the car is on the ground.
Lift the front of the vehicle using the floor jack at the manufacturer's recommended lift points. Once raised, position jack stands under the frame rails or subframe. Lower the jack onto the stands. Remove wheels completely.
Locate the two caliper guide pins (usually 12mm or 14mm). Remove them with a socket or hex key. Set them aside in a clean container.
Slide the caliper upward off the rotor. Do not let it hang by the brake line. Use a bungee cord or wire hanger to suspend it from the control arm.
Remove the old brake pads from the caliper bracket. Note any wear indicators or alignment clips.
Remove the two large bolts securing the caliper bracket to the steering knuckle (usually 14mm or 17mm). Tap the bracket lightly with a rubber mallet if it's seized.
Once the bracket is off, the rotor should slide off freely. If it's stuck, tap the face of the rotor with a hammer to break the rust bond, or use a pry bar between the hub and rotor edge.
Thoroughly clean the steering knuckle mounting surface and caliper bracket with a wire brush. Remove all rust and debris.
Wipe the new rotors with brake cleaner. Do not touch the friction surface with bare hands. Oils from skin can cause brake fade.
Apply a thin layer of copper anti-seize to the rotor hat center and outer edge where it contacts the knuckle.
Slide the new rotor onto the hub. Hand-tighten the center bolt if applicable. Ensure it's seated flush against the hub face.
Reinstall the caliper bracket. Torque the bolts to manufacturer spec (typically 75-85 ft-lbs). Reinstall the slider pins and apply high-temp brake grease.
Place new brake pads into the bracket. Ensure wear indicators face the correct direction (usually toward the rotor). Apply brake grease to the back of the pads and shims.
Use a C-clamp or piston tool to compress the caliper piston fully. If using ABS, you may need to rotate the piston clockwise while pushing.
Slide the caliper back over the rotor and align the guide pins. Torque to spec (usually 25-30 ft-lbs).
Reinstall wheels and torque lug nuts in a star pattern. Lower the vehicle completely.
Before driving, pump the brake pedal 5-10 times until firm. Check fluid level in the reservoir (it will have dropped from compressing pistons).
Bed-in procedure: Drive to 35 mph, brake firmly to 5 mph. Repeat 5 times. Drive slowly to cool. Avoid hard stops for 200 miles.
The piston rotation tip saved me! My 2018 Honda took 2 full clockwise turns before it retracted. Thanks for the detailed torque specs.
Question: Can I use lithium grease instead of dedicated brake lubricant for the slider pins?
@GarageQueen Stick to high-temp silicone or copper-based brake grease. Lithium degrades under caliper heat and will cause sticking.
