Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear.
2
Check brake pads for even thickness and signs of wear.
3
Examine suspension components, including control arms and bushings, for damage or wear.
4
Verify wheel lug nut torque to ensure proper installation.
5
Check tire balance and alignment for any discrepancies.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Use a jack to lift the vehicle and support it with jack stands.

2. Remove Wheel

Use a socket set to loosen the lug nuts while the wheel is still on the ground.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Inspect: Check the brake rotors for warping using a dial indicator or by visually checking for uneven surfaces.
Replace (if necessary):
1. Remove the caliper by unscrewing the caliper bolts with the appropriate socket.
2. Slide the caliper off the rotor and hang it securely using a wire to avoid straining the brake line.
3. Remove the old rotor by unscrewing the retaining screws (if equipped) and pulling the rotor off the hub.
4. Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
5. Install the new rotor and secure it with screws.

4. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads; they should be replaced if they are worn down below the manufacturer's specifications.
Replace (if necessary):
1. Remove the old brake pads from the caliper bracket by sliding them out.
2. Compress the caliper piston using a brake caliper tool to create space for the new pads.
3. Insert the new pads into the caliper bracket, ensuring they are aligned correctly.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 76-83 ft-lbs for RAV4).
Test drive the vehicle to ensure the shaking has stopped.
