I just used a channel-lock pliers to colapse the caliper. It screws in with screw threads. I had never changed rear disk brakes that worked this way. But when it was obvious that my C-clamp was not colapsing the caliper, I realized it worked by a different method. So screw it down as far as you need it, pop on the new pads and your set. I did open the bleeder valve because I was at my wits end when the C-clamp didn't work. So you may not even need to open the system to compress the piston, it may just screw down without having to let air into the system.
apply your brakes gently as you accelerate
The front brakes on any vehicle do most of the stopping. When you apply the brakes the weight shifts to the front of the vehicle. For this reason the front brakes are needed more than the rear. Try stopping a vehicle with just the hand brake which applies only the rear brakes.
you shpuld drive slowly to dry them
That would be the power brake vacuum operated 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..

no, that sounds like the brakes are grinding because the are ready to be changed, check them out immediately.
apply your brakes gently while accelerating at the same time
A piston on each end of the wheel cylinder pushes outward when the brakes are applied. This pushes the brake shoes against the brake drum and stops the vehicle. The pistons are forced out by the pressure of the brake fluid inside the wheel cylinder when you apply the brakes.

un equal adjustment of brakes will cause one brake to apply earlier and harder than other brake
A car has to have brake fluid to allow for the effective operation of the brakes to stop the car. When we apply pressure to the brake pedal, brake fluid, which is largely incompressible, will transfer that pressure to the pistons that operate the in the calipers or the pistons that operate the brake shoes. Further, the fluid must be of the correct type for the system in which it is used. The continued safe operation of the brakes may be compromised by the wrong fluid.

Time for new brakes or adjustment.
it broke
the master cylinder is designed so that when the brakes are applied, the pistons (primary and secondary) closes the compensating port and opens intake port. this allows brake pressure to be formed in brake system to apply brakes and allows brake fluid to fill behind pistons (through intake ports) when you release the brakes, the primary and secondary piston springs push their pistons (inside the master cylinder) to its rest position, faster than fluid can fill the chambers. this causes the brake fluid to flow past the piston cups (this happens when the rubber cup flexes foward) as the pistons pass the compensating port, brake fluid is allowed to return to the master cylinder reservoir. the intake and compensating ports act as a breather for the master cylinder. hope this answers your queston :)
