•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow the brakes to cool before handling any components to prevent burns.

Symptoms

•Steering wheel shakes when applying brakes
•Vibration felt in the brake pedal
•Increased stopping distance
•Uneven tire wear
•Possible noise during braking (squeaking or grinding)

Diagnostic Steps

1
Inspect brake pads for wear and ensure they are not excessively worn or damaged.
2
Check brake rotors for warping or scoring using a runout gauge.
3
Examine wheel alignment and tire balance using alignment equipment.
4
Inspect suspension components for wear or damage (ball joints, tie rods, etc.).
5
Check tire condition and pressure to ensure proper inflation and tread depth.

2
Check brake rotors for warping or scoring using a runout gauge.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues while working on brake components.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads and Rotors

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Check brake pads for wear; replace if they are below the recommended thickness (usually 3mm).
Inspect Brake Rotors:
- Measure rotor thickness and runout using a caliper and runout gauge.
- If warped (exceeds specifications), replace the rotors.
- If within tolerance, resurface the rotors if necessary.
Install New Pads and Rotors:
- Install the new rotors and pads in reverse order.
- Ensure to apply brake grease to the back of the pads to reduce noise.

4. Wheel Alignment and Balancing

After brakes are serviced, check the wheel alignment and balance.
Adjust alignment settings to manufacturer specifications using alignment equipment.
Balance the tires if necessary.

5. Reassemble and Test

Replace the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten the lug nuts to the manufacturer's torque specification (typically around 76 ft-lbs).
Reconnect the battery.
