Sounds like you have a problem with a wheel sensor or a toner ring. When you step on the brakes the computer looks at the sensor and toner rings at the wheels. The sensor could have a break in a wire or you could have a cracked toner ring giving your computer a false reading. That would tell your computer to engage the "Hold release apply cycle" which is the noise your hearing. I took my car to Meineke and they had it fixed in a day. The shop would need a good scanner and a good Tec. My does. So the first thing you need to do is get the car scanned by some one who knows how to interpret what he's reading.

If the fluid was way down, chances are 95% there's a leak in the system. In rare cases, the power brake booster can suck up fluid from the master cylinder and burn it, but that is rare, and there are many hints that this is happening, as the engine often smokes and protests.
 
You'd have to get under and examine for leakage at each of the 4 wheels, for starters.
 
It's also rare, but possible, that the master cylinder can leak down under the brake pedal and seep into the carpeting, but again, one would tend to smell this or see it.

#16 of 17 2005 Grand Marquis braking problem by chesty1

Several times our 2005 GM has seemed to stop decelerating suddenly while braking. It happened again today with my daughter driving. She had the brakes to the floor and the car surged ahead three times, as if the brakes were released then reapplied, almost ramming into the car ahead.
 
Some months earlier, my wife was braking and the car wouldn't stop. She shifted the auto transmission into park to stop the car. We had the car serviced and the brakes "fixed," but the braking problem is intermittent.

#17 of 17 2008 Grand Marquis - replace brake pads, rotors by jamesja

Dec 17, 2010 (7:51 pm)

I've found quite a lot on the Internet about doing brake jobs on Grand Marquis--up to 2004 model year. Anything I should know that would be different about this on my 2008 (front brakes)?
 
I'm at 51k miles, I think that's pretty good for the OEM pads.
 
Any recommendation for replacement pads brands?
