Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brake components to cool before servicing.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Shaking or vibration felt in the steering wheel when braking
•Pulsation in the brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise coming from the brakes (grinding or squeaking)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a runout gauge.
2
Check brake pads for thickness and even wear across the surface.
3
Examine suspension components (tie rods, control arms, bushings) for signs of wear or damage.
4
Perform a visual inspection of wheel bearings for play or noise.
5
Test drive the vehicle to confirm the presence and severity of vibrations.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift Vehicle

Use a jack to lift the front of the RAV4 and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Remove brake caliper by unbolting it (typically 2 bolts).
- Secure the caliper with a bungee cord to avoid strain on the brake line.
- Remove the rotor by unscrewing any retaining screws if present.
- Measure rotor thickness and check for warping with a runout gauge. Replace if out of specifications.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads, ensuring they are properly seated.

4. Reinstall Components

Reinstall the rotor, ensuring it is properly aligned.
Reattach the brake caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 18-25 ft-lbs).
Repeat the process for the other side.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Torque lug nuts to manufacturer specifications (typically 76-86 ft-lbs).
Test drive the vehicle to ensure the issue is resolved.
