2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow brakes to cool before touching components to avoid burns.
•Test drive the vehicle to ensure no shaking or vibrations occur during braking.
•Check for any unusual noises from the brakes.
•Verify that the vehicle tracks straight during braking.
•Regularly inspect and maintain brake components as per the manufacturer's schedule.
•Replace brake pads and rotors as needed to avoid warping.
•Ensure proper wheel alignment and balance periodically.

Symptoms

•Steering wheel shakes or vibrates when braking
•Vehicle pulls to one side during braking
•Brake pedal pulsates or feels uneven
•Increased stopping distance
•Unusual noise from brakes during braking (squealing or grinding)

Diagnostic Steps

1
Inspect brake rotors for warping by measuring thickness with a micrometer.
2
Check brake pads for uneven wear and sufficient thickness.
3
Examine suspension components, including control arms and tie rods, for play or damage.
4
Inspect wheel alignment and balance for any discrepancies.
5
Scan the vehicle’s onboard computer for any fault codes related to the braking system.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Safety warning: Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper bolts and carefully lift the caliper off the rotor.
3. Remove the rotor from the hub.
4. Measure the rotor thickness; if below specifications or warped, replace with new rotors.
5. Install new rotors, ensuring they are properly seated.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the brake pads for thickness; if worn beyond specified limits, replace them.
2. Ensure the caliper slides are clean and lubricated.
3. Install new brake pads, ensuring they are correctly positioned.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, tie rods, and bushings for wear or damage.
2. Replace any damaged components with OEM parts to ensure proper fit and function.

5. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that the wheels are balanced and aligned according to manufacturer specifications.
