⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the vehicle’s power before working on electrical systems.
•Allow the vehicle to cool down before handling components after use.

Symptoms

•Shaking or vibration felt through the steering wheel when braking
•Increased pedal effort required to stop the vehicle
•Uneven wear on brake pads or rotors
•Noise, such as grinding or squeaking, during braking
•Warning lights illuminated on the dashboard (e.g., ABS light)

Diagnostic Steps

1
Inspect brake pads for wear and proper thickness.
2
Check the brake rotors for warping or uneven surfaces using a dial indicator.
3
Examine brake calipers for proper operation and any signs of sticking or binding.
4
Verify tire balance and alignment, as they can contribute to vibrations.
5
Scan for any related error codes using an OBD-II scanner.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is powered off before starting work.

2. Inspect Brake Components

Tools Required: Socket set, torque wrench, dial indicator, safety goggles, gloves.
Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if less than 3mm thick.
Check rotors for warping using a dial indicator. If rotors are warped beyond specifications (usually over 0.002 inches), they need to be resurfaced or replaced.

3. Replace or Resurface Brake Rotors

If rotors are warped, remove the calipers by loosening bolts and hanging them without stressing the brake lines.
Remove the old rotors and clean the hub surface with a wire brush.
Install new rotors or take the old ones to a machine shop for resurfacing.
Reinstall the calipers and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs, check the service manual for exact values).

4. Replace Brake Pads (if necessary)

If brake pads are worn, remove them from the caliper bracket.
Apply brake grease on the caliper bracket where the pads contact.
Install new brake pads ensuring they are properly seated.
Reinstall the wheel and torque lug nuts to specifications (usually around 100-120 ft-lbs).

5. Final Checks

Reconnect any electrical components that were disconnected during the process.
Lower the vehicle and pump the brake pedal to ensure proper caliper function and brake engagement.
