Solution

1. Preparation

Gather necessary tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool if brakes were recently used.

2. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, jack and jack stands, lug wrench, rotor puller.
Remove the wheel using the lug wrench.
Check rotor thickness and runout. If warped, proceed to replace.
Remove the caliper by unscrewing the caliper bolts and hanging it safely.
Remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install the new rotor, ensuring it is seated properly.
Reinstall the caliper and tighten the bolts to manufacturer specifications (usually around 25-35 ft-lbs).

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear. If below the minimum thickness (usually 3mm), replace them.
Tools Required: Brake pad spreader, brake cleaner, torque wrench.
Remove the caliper pins and slide the caliper off the pads.
Remove old pads and clean the caliper bracket with brake cleaner.
Install new pads and ensure they are properly aligned.
Reinstall the caliper and tighten bolts to manufacturer specifications.

4. Inspect Suspension and Wheel Bearings

Inspect suspension components for any visible damage, wear, or loose bolts.
Tools Required: Pry bar, torque wrench.
Check wheel bearings for play by grasping the wheel at 12 and 6 o'clock and wiggling it. Replace if there is excessive play or noise.
Reassemble any components and ensure all bolts are torqued to specifications.
