my Ford Mustang S550 (2015-2023) shakes when braking, what should I do

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the battery to prevent electrical issues during work.

2. Inspect and Replace Brake Rotors

1. Lift the Vehicle

   • Use a hydraulic jack to lift the front or rear of the vehicle as needed.
   • Secure with jack stands.

2. Remove Wheel

   • Use a socket set to remove the lug nuts and take off the wheel.

3. Check Rotor Condition

   • Use a dial indicator to measure rotor runout; replace if warped beyond manufacturer specifications (usually 0.002 inches).

4. Replace Rotor (if necessary)

   • Remove caliper bolts using a socket set and slide the caliper off.
   • Unscrew the rotor mounting screws (if applicable) and remove the rotor.
   • Install the new rotor, ensuring it is clean and properly seated.
   • Reattach the caliper and torque bolts to manufacturer specifications (typically 25-35 lb-ft).

3. Inspect and Replace Brake Pads

1. Check Brake Pads

   • Inspect pad thickness; replace if below 3mm.

2. Replace Brake Pads (if necessary)

   • Remove the caliper bolts and slide the caliper off.
   • Remove old pads from the caliper bracket.
   • Install new pads, ensuring they are properly aligned.
   • Reattach the caliper and torque bolts to manufacturer specifications.

4. Reassemble and Test

1. Reinstall Wheel

   • Place the wheel back onto the hub and hand-tighten lug nuts.

2. Lower Vehicle

   • Remove jack stands and lower the vehicle back to the ground.

3. Torque Lug Nuts

   • Use a torque wrench to tighten the lug nuts to the specified torque (typically 100-120 lb-ft).
