Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, brake cleaner, torque wrench, replacement brake pads, brake grease.
Raise the vehicle using the jack and secure it on jack stands.
Remove the wheel associated with the affected brake system.

2. Remove Brake Caliper

Sub-steps:
1. Use a socket set to remove the caliper mounting bolts.
2. Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid strain on the brake line.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Inspect the pads for uneven wear; if necessary, replace with new pads.
3. Apply brake grease to the back of the new pads to prevent noise.

4. Check and Service Brake Caliper

Sub-steps:
1. Inspect the caliper for any signs of damage or sticking.
2. If necessary, rebuild or replace the caliper.
3. Lubricate the caliper slide pins with brake grease and ensure they move freely.

5. Reassemble Braking System

Sub-steps:
1. Reposition the caliper over the new pads and secure it with the mounting bolts.
2. Use a torque wrench to tighten the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).

6. Reinstall Wheel and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications (usually 76-83 ft-lbs).
