Bad Vibration when braking at high speed

[pdfbjf]

My 2005 Freestar Vibrates terribly when braking from high speed. It is NOT the brake pads or rotor, feels like loose in front end, but no shimmy even at 85+MPH. Could it be a steering part or suspension part?

I can't say about your y/m. On older, different makes and models, I've seen the piston freeze-up in the brake caliper, cause a terrible shudder, when you step on the brake. You might check for ABS codes, see if it shows anything.

These actually had a known issue of brake harshness caused by the rear brakes. Ford made an updated pad and rotors were to be turned if not too rusty.
