⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Allow the brakes to cool down before starting any work.

Symptoms

•Vibrations felt in the steering wheel or brake pedal during braking
•Uneven brake pad wear
•Pulsating brake pedal
•Noise when braking (grinding or squeaking)
•Vehicle pulling to one side when braking

Diagnostic Steps

1
Inspect brake pads for wear and thickness.
2
Check brake rotors for warping or uneven surfaces using a dial gauge.
3
Examine suspension components (control arms, bushings, and tie rods) for damage or wear.
4
Check wheel alignment and balance.
5
Scan for any error codes related to the brake system using an OBD-II scanner.

Solution

Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, dial gauge, brake cleaner, and replacement brake pads and rotors if needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect Brake Components

Raise the vehicle using a jack and secure it on jack stands.
Remove the front wheels for access to the brake assembly.
Inspect brake pads for wear: if less than 3mm thick, replace them.
Measure the brake rotors using a dial gauge. If runout exceeds manufacturer specifications (typically 0.002 inches), they should be resurfaced or replaced.

3. Replace Brake Pads and Rotors (if needed)

Remove caliper bolts using a socket set and carefully lift the caliper off the rotor.
Suspend the caliper using a bungee cord to avoid stress on the brake line.
Remove the old brake pads and replace them with new ones, ensuring proper orientation.
If replacing rotors, remove the rotor retaining screws and slide the rotor off the hub. Install the new rotor and secure it with screws.
Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.

4. Inspect and Replace Suspension Components (if necessary)

Check control arms, bushings, and tie rods for any signs of wear or damage.
If any components are worn, replace them according to factory specifications, using a torque wrench to ensure proper installation.

5. Reassemble and Test

Reinstall the front wheels and torque the lug nuts to the manufacturer's specifications.
Lower the vehicle and perform a test drive to evaluate braking performance and ensure vibrations have been resolved.
