Id check the vacuum booster behind the brake master cylinder. I have seen cases of boosters on fords cracking causing the booster not to work properly. Resulting in a hard pedal and hard to pull up the car.
Also the hose to the booster and the check valve where the hose connects to the booster.
Well I seem to have a similar situation.. I would say your 'ping' is a bit of a 'sprong' on my 95 Windstar. Further the brake pedal seems to bind, makes the sound and not engage the brakes.. I can apply more pressure and pass through the bind to engage the brakes or with some pumping of the pedal the binding dissipates and the brakes engage properly.. I was wondering if this is similar to your situation? Unfortunately I do not have the answer; I am on the 'net today looking for information! Should I find any info pf value I will post here..

Light is usually comes on, when there is a problem with pressure in brake lines. Inspect the brake fluid level, and check for leaks.
When you park your vehicle.
rear brakes need adjustment srar wheel froozen
If the parking brake does not engage fully, the rear (shoe type) brakes need to be adjusted or replaced.
Check the refrigerant pressure. There is a sensor that detects the pressure of the refrigerant. If the pressure is not high enough the compressor will never engage.
the thut
The brakes my lock up without touching them if a foreign object has become lodged between the pad and the rotors. A failure in the hydraulics may also cause the brakes to engage on their own.
It supplies air to the service chambers of the brake chambers in order to engage the brakes.
All four brakes should engage at the same time. You probably need to bleed your front brakes. If road conditions are wet or you haven't driven the car in a while, drum brakes sometimes "grab". Many cars have rear drum brakes and front disc, this could be what you're expieriencing.
The ac pressure cycling switch is designed to engage or dissengage the clutch to keep the proper pressure in the system.
If the switch is bad or you don't have enough oil pressure the ECU won't engage VTEC as to prevent damaging itself. Get a new switch.
