⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and use wheel chocks to prevent movement.
•Always wear safety goggles and gloves.
•Disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before handling brake components.

Symptoms

•Vehicle pulls to one side during braking
•Uneven brake pad wear
•Brake pedal feels uneven or spongy
•Steering wheel vibrates during braking
•Increased stopping distance

Diagnostic Steps

1
Inspect Brake Pads and Rotors: Visually examine the brake pads for uneven wear and check the rotors for warping or damage.
2
Check Brake Fluid Level: Ensure that the brake fluid is at the recommended level and free of contamination.
3
Examine Brake Calipers: Inspect the brake calipers for proper operation and ensure they are not sticking or seized.
4
Test Brake Lines: Assess brake lines for leaks or blockages that could influence brake performance.
5
Evaluate Suspension Components: Check for worn or damaged suspension parts such as control arms, bushings, and struts that could cause misalignment.
6
Perform a Wheel Alignment Check: Verify wheel alignment to rule out any alignment issues contributing to pulling during braking.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and a multimeter for any electrical checks.
Safety Warnings: Ensure the vehicle is on a flat surface and use wheel chocks to prevent movement. Always wear safety goggles and gloves.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake pads for wear; replace if they are below the manufacturer's specifications.
4. Clean the brake caliper and rotor with brake cleaner.
5. Reinstall the new brake pads, ensuring they are properly aligned and seated.
6. Reinstall the wheel and torque to the manufacturer’s specification.

3. Check and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are warped or damaged, remove the caliper and rotor assembly.
2. Install new rotors, ensuring to clean any protective oil from the rotor surface.
3. Reinstall calipers and ensure they move freely.
4. Reconnect any electrical connections if applicable.

4. Inspect and Repair Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and struts for signs of wear or damage.
2. Replace any worn components with new parts.
3. Perform a wheel alignment to ensure all wheels are properly aligned post-repair.
