⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Uneven thickness of brake pads between left and right wheels
•Scraping or grinding noise during braking
•Vibration or pulsation in the brake pedal
•Vehicle pulling to one side during braking
•Increased brake dust on one wheel compared to the other

Diagnostic Steps

1
Inspect the brake pads visually for signs of uneven wear.
2
Measure the thickness of each brake pad using a caliper to identify discrepancies.
3
Check the brake rotors for warping or uneven surfaces.
4
Examine the caliper operation for sticking or seizing.
5
Inspect the brake lines for kinks or blockages that may affect fluid flow.
6
Test the brake fluid for contamination or moisture content.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use a jack and jack stands to lift the vehicle safely.

2. Remove Wheels

Loosen the lug nuts on the front or rear wheels (depending on where the issue is observed).
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to gain access to the brake components.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by unbolting it (usually two bolts). Inspect the pads for wear patterns and thickness.
Brake Rotors: Check for signs of warping, scoring, or uneven surfaces. If necessary, measure the rotor thickness with a micrometer.
Calipers: Ensure calipers slide freely on their pins and that the piston retracts smoothly. Lubricate the caliper pins if they are sticking.

4. Address Issues Found

If pads are unevenly worn, replace them with new pads. Ensure to use high-quality pads compatible with the Mustang S650.
Resurface or replace any warped rotors.
If calipers are sticking, either clean and lubricate them or replace them if severely damaged.

5. Reassemble and Lower the Vehicle

Reinstall the brake caliper and torque the bolts to manufacturer specifications (usually 25-35 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to manufacturer specifications (usually 100-130 ft-lbs).
