Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Use wheel chocks for added safety.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Caliper tool

2. Remove Wheel

Loosen lug nuts while the wheel is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads: if worn down to the indicator, replace them.
Clean the caliper and rotor surfaces with brake cleaner.

Sub-steps for Pad Replacement:

Remove old brake pads from the caliper bracket.
Compress the caliper piston using a caliper tool.
Install new brake pads in the caliper bracket.
Reattach the caliper over the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, replace them.
Remove the rotor by unscrewing the retaining screws or bolts.
Install new rotors, ensuring they are secure.

5. Reassemble Components

Reattach the caliper and tighten bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs).
