Diagnostic Steps

1
Inspect the brake pads for wear and thickness using a visual inspection.
2
Check the brake rotors for scoring or warping by measuring rotor thickness.
3
Listen for any noise while pressing the brake pedal with the vehicle stationary.
4
Check brake fluid level and condition in the master cylinder reservoir.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and place wheel chocks behind the rear wheels.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Socket set
Brake cleaner
C-clamp or brake caliper tool

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Use a socket to remove the caliper bolts.
Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for any damage or corrosion and clean it if necessary.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check rotor condition; if warped or scored, remove the caliper bracket.
Remove the rotor by unscrewing any retaining screws (if equipped) and pulling it off the hub.
Clean the hub surface where the rotor sits.
Install new rotors, ensuring they are properly aligned and seated.

5. Reassemble Braking Components

Reinstall the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-30 lb-ft, but verify with service manual).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque (usually 80-100 lb-ft).

6. Final Checks

Lower the vehicle and remove wheel chocks.
Press the brake pedal several times to seat the pads against the rotors.
Check the brake fluid level again and top off if necessary.
