Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a lug wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Inspect the brake pads for thickness; replace if worn below specifications (typically 3mm).
2. Check the brake rotor for wear, scoring, or warping; replace if necessary.
3. If replacing, remove the caliper by unbolting it and hang it securely.
4. Remove old brake pads and replace them with new ones.
5. If necessary, replace the rotor by unbolting it from the hub.
6. Reinstall the caliper and torque bolts to manufacturer specifications (generally around 25-30 ft-lbs).
Tools Required: Socket set, torque wrench, brake cleaner, new brake pads, new rotors.

4. Check Brake Fluid and Hoses

Sub-steps:
1. Check brake fluid level in the reservoir; top off with manufacturer-recommended fluid if low.
2. Inspect brake lines and hoses for leaks or damage; replace if any issues are found.
Tools Required: Brake fluid, funnel, visual inspection tools.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 100-120 ft-lbs).
3. Test the brakes by pressing the pedal several times to ensure proper engagement.
Tools Required: Lug wrench, torque wrench.
