Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed.

2. Lift Vehicle

Using a jack, lift the front of the vehicle and secure with jack stands.
Remove front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping and grooves using a dial indicator.
Remove Calipers: Loosen caliper bolts and remove the brake caliper. Support it with a bungee cord, do not hang by the brake line.
Remove Rotors: Take off the rotor after removing the retaining screws if present. If rotors are warped, replace them.
Install New Rotors: Mount new rotors onto the hub and secure with retaining screws.

4. Inspect and Replace Brake Pads

Inspect Pads: Check for wear; if below 3mm thickness, replace.
Replace Pads: Remove the caliper bracket, replace old pads with new ones, and apply brake grease to the backing of the pads.
Reassemble Caliper: Reattach the caliper over the new pads and tighten caliper bolts to manufacturer specifications (typically 25 Nm).

5. Check and Replace Suspension Components (if necessary)

Inspect control arms, tie rods, and bushings for wear.
Replace any worn components using appropriate tools, ensuring to torque bolts to manufacturer specifications.

6. Reassemble and Lower Vehicle

Reinstall the front wheels and lower the vehicle back to the ground.
Torque lug nuts to manufacturer specifications (typically 100 Nm).
