Diagnostic Steps

1
Inspect the brake rotors for warping or uneven wear.
2
Check brake pads for thickness and signs of uneven wear.
3
Measure rotor thickness using a micrometer to ensure they are within specifications.
4
Examine the brake calipers for proper operation and signs of sticking.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Check for warping using a dial indicator or by visually inspecting while rotating the rotor.
If warped beyond specifications (usually more than 0.002 inches), proceed to replace the rotor.
Remove the caliper by unscrewing the caliper bolts and hanging it safely with a bungee cord (do not let it dangle by the brake line).

B. Replace Brake Pads

Use a C-clamp to push the caliper piston back for easier pad removal.
Remove the old brake pads and install new ones, ensuring they are oriented correctly.

C. Install New Rotors (if necessary)

Remove the old rotor by unscrewing any retaining screws or using a hammer to gently tap it off if rusted.
Install the new rotor and secure it in place.

4. Reassemble

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle

Remove the jack stands and lower the vehicle.
Torque the lug nuts to the specified value (usually around 100-120 ft-lbs).

6. Final Check

Reconnect the battery.
Pump the brake pedal to ensure proper engagement of the calipers.
Check for any leaks and ensure all components are secure.
