Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake cleaner, runout gauge.
Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Remove the caliper bolts and hang the caliper securely without straining the brake line.
3. Remove the brake pads and inspect them for wear.
4. Use a runout gauge to measure the rotor; if warping exceeds manufacturer specifications (typically 0.002 inches), replace the rotor.
5. Clean the new rotor's surface with brake cleaner before installation.
6. Install the new rotor onto the hub.

3. Replace Brake Pads

Tools Required: Same as above.
Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Apply a thin layer of brake grease to the backing of the pads to prevent noise.
3. Reinstall the caliper over the new pads and torque caliper bolts to manufacturer specifications.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque lug nuts to the specified value.
2. Reconnect the battery.
3. Test the brakes by pressing the pedal several times to seat the pads against the rotors.
4. Perform a test drive to ensure the shaking has been resolved.
