⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brake components to cool before working on them to avoid burns.
•Ensure the vehicle is securely supported on jack stands before working underneath.

Symptoms

•Squealing noise during braking
•Vibration felt through the brake pedal
•Reduced braking performance
•Brake warning light illuminated
•Dust accumulation on wheels

Diagnostic Steps

1
Inspect brake pads for wear and thickness using a visual inspection.
2
Check brake rotors for scoring or warping by measuring with a micrometer.
3
Examine brake fluid level and condition in the master cylinder reservoir.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, and safety glasses.
Lift the vehicle using a jack and secure it with jack stands. Remove the wheel using a lug wrench.

2. Inspect Brake Pads and Rotors

Remove the caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor without stretching the brake line.
Inspect the brake pads for wear; replace if they are below 3mm in thickness.
Check the rotors for scoring or warping. If warped, replace or resurface as needed.

3. Clean Brake Components

Use brake cleaner to thoroughly clean the brake pads and rotors.
Clean the caliper bracket and ensure no debris is present that could cause noise.

4. Reassemble Brake Components

If necessary, replace the brake pads and/or rotors.
Reinstall the caliper over the new or cleaned pads and rotor. Ensure it slides smoothly.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

5. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value (usually 80-100 ft-lbs for F-150).
