However, here's a general overview of the potential repair areas and what they might entail:
1. Brake Pads:
* Problem: Worn-out brake pads are the most common brake issue. They'll produce squealing, grinding, or a pulsating brake pedal.
* Repair: Replacing brake pads involves removing the caliper, removing the old pads, installing new pads, and reassembling the caliper. This requires specialized tools like caliper compression tools and potentially torque wrenches for proper tightening.
2. Brake Rotors:
* Problem: Worn, warped, or scored rotors will cause vibrations in the brake pedal, squealing, or reduced braking power.
* Repair: Rotors can sometimes be resurfaced (machined) to remove imperfections. However, if they're too worn, they'll need replacement. This requires removing the caliper and wheel.
3. Brake Calipers:
* Problem: Seized or leaking calipers can prevent proper braking or lead to uneven brake pad wear. You might notice a dragging brake, uneven braking, or a soft brake pedal.
* Repair: Calipers can sometimes be rebuilt with new seals and pistons. However, replacement is often more cost-effective and reliable.
4. Brake Lines and Hoses:
* Problem: Leaks in brake lines or hoses will drastically reduce braking performance and can lead to brake failure.
* Repair: Repairing brake lines usually involves replacing the damaged section. This requires careful bleeding of the brake system afterward.
5. Master Cylinder:
* Problem: A failing master cylinder can cause a spongy brake pedal, low brake fluid, or complete brake failure.
* Repair: The master cylinder usually needs to be replaced. This is a complex repair requiring extensive bleeding of the brake system.
6. ABS System:
* Problem: Issues with the Anti-lock Braking System (ABS) can cause the ABS warning light to illuminate, unusual brake pedal feel, or reduced braking performance.
* Repair: Diagnosing and repairing ABS problems often requires specialized diagnostic tools and knowledge of the ABS system's components.
What to do instead of DIY:
If you suspect a brake problem on your Ford Expedition, it is strongly recommended to take it to a qualified mechanic or dealership. Brake repair is critical for safety, and a professional will have the expertise, tools, and diagnostic equipment to properly assess and repair the issue. Attempting a DIY repair without the necessary skills and tools can result in costly mistakes and put you and others at risk.
