Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Brake Rotors

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Sub-steps:
1. Jack up the vehicle and secure it with jack stands.
2. Remove the front or rear wheels using a lug wrench.
3. Remove caliper bolts and carefully detach the brake caliper from the rotor.
4. Remove the rotor from the hub and inspect for warping using a runout gauge.
5. If warped, replace with new rotors. Ensure the new rotor is clean and free of oil or grease.
6. Reinstall the rotor and caliper, tightening bolts to the manufacturer's specifications (typically around 25-30 Nm for caliper bolts).

3. Replace Brake Pads

Tools Required: Piston tool or C-clamp, socket set.
Sub-steps:
1. After removing the caliper, take out the old brake pads.
2. Inspect the caliper for any fluid leaks and ensure the piston is retracted using a piston tool or C-clamp.
3. Install new brake pads in the caliper bracket.
4. Reattach the caliper over the new pads and secure with bolts.

4. Inspect and Replace Suspension Components (if needed)

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Check control arms, bushings, and struts for wear or damage.
2. If components are damaged, remove them using the appropriate socket sizes.
3. Replace with new OEM or quality aftermarket parts.
4. Torque all bolts to the specified values according to manufacturer specifications.

5. Wheel Alignment and Balancing

Tools Required: Alignment tools (if doing in-house) or visit a service center.
Sub-steps:
1. After reassembling, check that the wheels are properly aligned.
2. If necessary, take the vehicle to a professional for alignment and balancing.
