Diagnostic Steps

1

2
Check the brake rotors for scoring or warping.
3
Examine the brake calipers for proper operation and signs of leakage.
4
Inspect brake lines for any damage or air in the system.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to avoid any electrical issues.

Tools Required:

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

Parts Required:

New brake pads
New brake rotors (if necessary)
Brake grease

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket and inspect the backing plate.
If the pads are worn down to the metal, replace them with new brake pads.
Apply brake grease to the backing of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors

Check the rotors for any visible damage or grooves.
If warped or excessively worn, remove the rotor by unscrewing the rotor retaining screws (if present).
Replace with new rotors and ensure they are clean of any oil or debris before installation.

5. Reassemble and Torque

Reinstall the caliper over the new pads and rotor, ensuring it moves freely.
Reattach caliper bolts and torque them to the manufacturer's specifications (usually around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands and tighten the lug nuts to the specified torque (usually around 80-100 lb-ft).
Reconnect the battery and perform a brake pedal test to ensure the system is operational.
