Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspection: Measure rotor thickness and check for warping.
Replacement:
1. Remove caliper bolts and detach the brake caliper from the rotor.
2. Hang the caliper using a bungee cord to avoid straining the brake line.
3. Remove the brake rotor from the hub.
4. Install new rotors, ensuring they are properly seated.
5. Reattach the caliper and torque the bolts to manufacturer specifications (typically around 25-35 Nm).

4. Inspect and Replace Brake Pads

Inspection: Check pad thickness; replace if below 3mm.
Replacement:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake caliper tool.
3. Install new pads in the caliper bracket.
4. Reinstall the caliper and torque as specified.

5. Suspension and Alignment Check

Inspect control arms and bushings for wear or damage.
If necessary, replace any damaged components.
Perform a wheel alignment after repairs.
