Important safety information - read before proceeding

•Always wear safety goggles and gloves when working on brake systems.
•Ensure the vehicle is securely supported on jack stands before working underneath.

Symptoms

•Squeaking or squealing noises when braking
•Grinding noise when brakes are applied
•Brake pedal feels soft or spongy
•Vibration or pulsation in the brake pedal
•Check brake warning light illuminated on the dashboard
•Reduced braking performance or longer stopping distances

Diagnostic Steps

1
Inspect brake pads visually for thickness; if they are less than 3mm, replacement is needed.
2
Check for any unusual noises while applying brakes during a test drive.
3
Measure the brake rotor thickness with a micrometer; if below manufacturer specifications, replacement is necessary.
4
Examine brake fluid level and condition; low or dirty fluid may indicate a problem.
5
Inspect brake lines for leaks or damage; any signs of fluid leakage require further investigation.
6
Test the brake response during a slow-speed stop to assess effectiveness and responsiveness.

Solution

1. Preparation

Gather necessary tools and safety gear.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being inspected.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel nuts and take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads:
- Check pad thickness; measure with a caliper if necessary.
- Look for uneven wear or cracking.
Brake Rotors:
- Inspect for scoring, rust, or warping; use a micrometer to ensure thickness is within specifications.
Calipers:
- Check for any leaks or sticking calipers.

5. Replace Components (if necessary)

Brake Pads:
- If pads are worn, remove the caliper bolts and slide the caliper off.
- Replace pads with new ones, ensuring they are fitted correctly.
Brake Rotors:
- If rotors are below specs, remove and replace them; ensure the rotor surface is clean before installation.

6. Reassemble and Test

Reinstall the wheel and tighten the lug nuts to the manufacturer’s torque specifications.
Lower the vehicle and pump the brake pedal a few times to seat the pads.
Test drive the vehicle to ensure brakes are functioning properly.
