Symptoms

•Squeaking or grinding noise when applying brakes
•Vibration or pulsation in the brake pedal
•Reduced braking responsiveness or longer stopping distances
•Warning light illuminated on the dashboard
•Brake fluid leak visible under the vehicle

Diagnostic Steps

1
Inspect brake pads visually through the wheel openings for thickness.
2
Listen for any unusual sounds while applying brakes during a test drive.
3
Check for any warning lights on the dashboard related to the braking system.
4
Measure brake rotor thickness using a micrometer or caliper to ensure they are within specifications.
5
Check for any leaks in the brake lines or around the brake calipers.
6
Test the brake pedal feel; it should be firm and responsive without excessive travel.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Use wheel chocks for added safety.
Tools Required: Jack, jack stands, lug wrench, brake cleaner, micrometer, socket set.

2. Remove Wheel

Loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect brake pads for wear; they should be at least 1/4 inch thick.
Check brake rotors for scoring or warping.
Inspect the brake calipers for leaks or damage.

4. Replace Brake Pads (if needed)

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar.
Remove the old brake pads from the caliper bracket.
Install new brake pads in the opposite order of removal, ensuring they are seated correctly.

5. Reassemble Components

Reinstall the brake caliper over the new brake pads.
Torque the caliper bolts to the manufacturer’s specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts to the manufacturer’s specified torque (typically 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper brake pad seating.
