my Ford Explorer's brake pedal goes to the floor what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Place wheel chocks behind the rear wheels for safety.

2. Check and Refill Brake Fluid

• Tools Required: Brake fluid, funnel
• Inspect the master cylinder reservoir; if fluid is low, refill it with the recommended brake fluid type (DOT 3 or DOT 4).
• Check for any visible leaks after refilling.

3. Inspect and Replace Brake Lines

• Tools Required: Wrenches, brake line cutter, new brake line
• If leaks are found, use a wrench to disconnect the damaged line and cut the affected section.
• Replace with a new brake line, ensuring all connections are tight and secure. Torque specifications should be followed (consult vehicle service manual).

4. Brake Caliper Inspection and Replacement

• Tools Required: Socket set, brake caliper tool
• Remove the wheel and inspect the caliper for any leaks or damage.
• If necessary, remove the caliper bolts and slide the caliper off the rotor.
• Replace with a new caliper if leaks or severe damage are observed.
• Reinstall the caliper and torque bolts to manufacturer specifications.

5. Brake Pad and Rotor Inspection

• Tools Required: Socket set, brake pad spreader
• Inspect brake pads for wear; replace if thickness is below 3mm.
• Inspect rotors for scoring or warping; resurface or replace as needed.
• Reinstall pads and rotors, ensuring proper alignment.
