Diagnostic Steps

1
Inspect brake pads for uneven wear and proper thickness.
2
Check brake rotors for warping or scoring.
3
Examine the brake calipers for proper function and any sticking issues.
4
Evaluate suspension components (e.g., control arms, bushings) for wear or damage.
5

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Securely place jack stands under the vehicle for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the front wheel.

4. Inspect and Replace Brake Components

A. Inspect Brake Pads and Rotors

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid stress on the brake line.
Inspect brake pads for wear; replace if thinner than 3mm.
Check the rotor for warping (using a runout gauge) or scoring; replace if necessary.

B. Replace Brake Pads (if needed)

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

C. Replace Brake Rotors (if needed)

Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
Install the new rotor, securing it with screws if applicable.

5. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (typically around 25-30 Nm).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle from the jack stands using the hydraulic jack.
Tighten the lug nuts to the specified torque (typically 120 Nm) in a crisscross pattern.
