⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow the vehicle to cool down before touching brake components to avoid burns.

Symptoms

•Steering wheel shakes or vibrates during hard braking
•Vehicle pulls to one side while braking
•Brake pedal feels pulsating or uneven when pressed
•Increased stopping distance
•Possible noise (squeaking or grinding) during braking

Diagnostic Steps

1
Inspect brake pads for wear and unevenness.
2
Check brake rotors for warping or thickness variation using a micrometer.
3
Examine suspension components (tie rods, control arms) for play or wear.
4
Inspect wheel balance and alignment.
5
Scan for any error codes relating to the braking system with an OBD-II scanner.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, micrometer, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is on a stable surface and engage the parking brake.

2. Wheel Removal

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Brake Inspection

Brake Pads: Remove the brake caliper by loosening the caliper bolts. Inspect the brake pads for uneven wear; replace if necessary.
Brake Rotors: Measure the thickness of the rotors with a micrometer. If they are below the minimum thickness or show signs of warping (visible grooves or uneven surfaces), replace them.

4. Suspension Inspection

Check suspension components such as tie rods and control arms for any signs of wear or looseness. If any components are found to be worn, replace them as needed.

5. Reassembly

If new brake pads or rotors were installed, ensure all components are torqued to manufacturer specifications (refer to service manual for specific torque values).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.
