Diagnostic Steps

1
Inspect brake pads for wear and replace if necessary.
2
Check rotor thickness and inspect for warping or scoring.
3
Examine brake calipers for proper operation and signs of sticking.
4
Test brake fluid for contamination or low levels.
5
Inspect suspension components (e.g., control arms, bushings) for wear.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it using a jack.
Place jack stands under the vehicle for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket set.
Slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads and compare them with the new ones for size.
Install the new brake pads, ensuring proper alignment.

4. Inspect and Resurface or Replace Rotors

Check the rotor surface for warping or scoring.
If warped, use a brake lathe to resurface the rotors or replace them if they are below minimum thickness specifications.
If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.

5. Reassemble Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
