Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always work on a flat surface and use jack stands for safety.
•Allow brake components to cool before handling to prevent burns.

Symptoms

•Shaking or vibrating sensation through the steering wheel during braking
•Increased pedal feel (hard or pulsating brake pedal)
•Noise from the brakes (grinding or squeaking)
•Uneven tire wear
•Pulling to one side while braking

Diagnostic Steps

1
Inspect brake pads and rotors for wear and damage.
2
Check brake rotor thickness with a micrometer to determine if they are within specifications.
3
Examine the brake calipers for proper function and any sticking components.
4
Inspect suspension components (ball joints, tie rods, bushings) for wear or damage.
5
Test drive the vehicle to confirm symptoms and assess severity.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Loosen lug nuts with a socket wrench but do not remove them completely.
Raise the vehicle using a jack and secure with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Remove caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Check the brake pads for wear; if below the minimum thickness, replace them.
Inspect Brake Rotors:
- Check for warping by using a dial indicator or visually inspect for grooves.
- If warped or below minimum thickness specifications, replace the rotors.
Replace Components:
- Install new brake pads and rotors, ensuring they are the correct fit for the model.
- Apply brake grease to the back of the pads and caliper slides to prevent noise.
- Reattach the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect Suspension Components

Examine ball joints, tie rods, and bushings for signs of wear.
Replace any damaged components as necessary, following manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then fully tighten the lug nuts to specifications.
Reconnect the negative battery terminal.
