Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

Tools Required:

Jack and jack stands
Lug wrench
Brake cleaner
Torque wrench
OBD-II scanner (if needed)

2. Inspect and Replace Rotors

Remove the wheel using a lug wrench.
Inspect the rotors visually for warping or uneven surfaces.
If warped, remove the caliper by unscrewing the mounting bolts and securing it away from the rotor.
Remove the brake pads from the caliper bracket and inspect for wear.
Unbolt the rotor from the hub (if necessary) and remove it.
Clean the hub surface with brake cleaner before installing new rotors.
Install new rotors and secure them properly.

3. Replace Brake Pads

Remove the caliper bracket from the mounting points.
Remove old brake pads from the bracket and compare thickness with new pads.
If pads are worn, install new pads into the caliper bracket.
Reattach the caliper brackets and ensure they are torqued to manufacturer specifications.

4. Bleed Brake System (if necessary)

Reconnect the negative battery terminal.
Fill the brake reservoir with fresh brake fluid.
Using a bleeder kit, start at the wheel furthest from the master cylinder (usually the right rear).
Open the bleeder valve, have an assistant press the brake pedal, then close the valve before releasing the pedal.
Repeat until there are no air bubbles in the fluid.
