⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before working on the brakes to avoid burns.

Symptoms

•Steering wheel shakes during braking
•Vibration felt in the brake pedal
•Uneven wear on brake pads or rotors
•Noise from the brakes (squeaking or grinding)
•Vehicle pulls to one side while braking

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear by measuring thickness and checking surface condition.
2
Check brake pads for wear and ensure they are properly seated in the calipers.
3
Examine suspension components (e.g., control arms, tie rods) for damage or wear.
4
Verify wheel alignment and balance to rule out issues not related to the braking system.
5
Test the brake calipers for proper operation and ensure they are not sticking.

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheels

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, impact wrench
Sub-steps:
1. Remove the caliper by unscrewing the bolts holding it in place.
2. Hang the caliper using a bungee cord to avoid straining the brake line.
3. Remove the rotor by unscrewing any retaining screws or clips.
4. Inspect the rotor for warping; replace if warped or below the minimum thickness specification.
5. Install the new rotor, ensuring it is seated correctly.

4. Inspect and Replace Brake Pads

Tools Required: Torque wrench
Sub-steps:
1. Remove old brake pads from the caliper bracket.
2. Inspect the caliper bracket for debris and clean if necessary.
3. Install new brake pads, ensuring they are properly oriented and seated.
4. Apply brake grease on the backing of the pads to reduce noise.

5. Reassemble and Torque Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper over the new pads and rotor.
2. Torque the caliper bolts to the manufacturer's specifications.
3. Reinstall the wheel, hand-tightening the lug nuts.
4. Lower the vehicle and torque the lug nuts to the specified value.

6. Final Checks

Tools Required: OBD-II scanner (if needed)
Sub-steps:
1. Ensure all tools and parts are cleared from the work area.
2. Test the brake pedal for firmness before driving.
3. Check for any error codes using an OBD-II scanner if the brake warning light was illuminated.
