2
Check brake rotor condition for scoring or warping.
3
Examine brake calipers for proper operation and any leaks.
4

Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear; if they are less than 1/4 inch thick, replace them.
Remove the caliper by unbolting it (usually requires a socket set).
Slide the caliper off the rotor and support it with a hanging wire (do not let it dangle on the brake line).
Remove the old brake pads from the caliper bracket and replace them with new pads.
Use brake lubricant on the back of the new pads to reduce noise.

4. Inspect and Replace Rotors (if necessary)

Check the brake rotors for grooves or warping; if damaged, replace them.
If replacing rotors, remove the caliper bracket and rotor by unbolting.
Install new rotors, ensuring they are clean and free of grease.
Reattach the caliper bracket with the specified torque (usually around 75-85 ft-lbs).

5. Reassemble and Test

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and torque the lug nuts to the specified value (usually around 75-100 ft-lbs).
Test brake function by pressing the pedal before driving to ensure proper engagement.
