Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
- Check the brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Inspect the rotors for signs of warping or scoring.
- If warped, replace with new rotors. If only minor scoring, consider resurfacing if applicable.

4. Reassemble Components

Brake Pads:
- If replacing, install new brake pads into the caliper bracket.
Brake Rotors:
- Install new or resurfaced rotors onto the hub.
Reattach the caliper over the new pads and rotor, ensuring it is aligned properly.
Tighten caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts initially, then lower the vehicle.
Once on the ground, torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).

6. Test Brakes

Pump the brake pedal a few times to ensure proper engagement before driving.
Test drive the vehicle to ensure the shuddering issue is resolved.
