•Allow brake components to cool before handling after driving.

Symptoms

•Steering wheel shakes or vibrates during braking
•Pulsation felt in brake pedal
•Increased stopping distance
•Noise from brakes (squeaking or grinding)
•Uneven tire wear
•Vehicle pulls to one side when braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and signs of uneven wear.
3
Examine suspension components for wear or damage, including bushings and control arms.
4
Inspect wheel bearings for play or noise.
5
Verify tire balance and alignment.
6
Scan for any error codes that might indicate electronic stability control issues.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Wheel Removal

Use a lug wrench to loosen lug nuts slightly without removing them.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Brake Component Inspection

Rotors:
- Inspect the rotor surface for grooves or warping.
- If warped, proceed to replace the rotor.
Brake Pads:
- Check the thickness of the brake pads; if below 3mm, replace them.
- Ensure pads are seated properly in the caliper.

4. Rotor Replacement (if necessary)

Remove the caliper by unscrewing the mounting bolts.
Slide the caliper off the rotor and hang it using a bungee cord to avoid straining the brake line.
Remove the rotor retaining screws, if applicable, and slide the rotor off the hub.
Install the new rotor and secure it with retaining screws.

5. Reassemble Brake Components

Reinstall the caliper over the new rotor and tighten the mounting bolts to the manufacturer's torque specification.
Replace brake pads if they were worn out.

6. Wheel Reinstallation

Place the wheel back on the hub.
Hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the specified torque.
