WE HAD REPLACED THE ROTORS, CALIPERS AND THE MASTER CYCLINDER AND STILL NO BRAKES. WE DID FILL ABOUT 3 PINTS OF BRAKE FLUID AND WHEN YOU BLEED THE BRAKES, NOTHING SEEMS TO SQUIRT OUT. WHERE HAS ALL THE BRAKE FLUID GONE?

things that have to be checked during a brake replacement process
the caliper pistons have to move back easily when fitting new pads
the caliper body has to move freely on the mounting pins to allow the centralization on the disc rotor
the brake bleeder nipple has to be opened when pushing the pistons back as the displaced fluid build sup pressure in the reservoir
check that the fluid level in the reservoir is not above the full line
check the brake master cylinder is operational and compensating ports are not blocked
basically the problems is that the pads are in contact with the disc and that is generating heat. that heat expands the brake fluid that has to be allowed to flow back to the reservoir
if the expansion of fluid is prevented either by over full reservoir or faulty mastery cylinder preventing the free flow back to the reservoir then the expansion applies the pad more tightly to the disc which in turns creates more heat and more expansion of the fluid
At this point and before you do anything else ,my steps would be to flush the system out using metholated spirits by filling the reservoir and then bleeding each wheel until clear fluid came out
when this is accomplished any black junk in the system is removed
fill the reservoir with new brake fluid and repeat the bleeding process until only brake fluid comes out
Metholated spirits is compatible with brake fluids and is recommended for the purpose
having cleaned out the system and ensured the free movement of the calipers on the mounting pins the pads should be in light contact with the discs and hubs should spin free after brakes are applied and released
In practice pads always touch the disc as there is no method of pulling the ads back and it is the air friction between pad and spinning disc that gives a minute clearance when travelling and if that ability is not allowed then the problems that you have will result
when you are done with a brake job it is always important to make sure you can slide the caliper both inward and outward by hand to ensure that there is no sticking, (that is with the pads in place and caliper piston completely depressed into the caliper) it is not rare to find that a piston that is very hard to depress back in the caliper is due to deterioration of the inner lining of the brake hose, if you have problems pushing the piston back into place most likely this is your problem. I have strong hands and is most vehicles I can push the piston back into the caliper by hand.
all dodge caravans from 2002 through 2011 have known problems with sticking calipers. if you google caravan brake problems you will see all the complaints. there are TBI's and recalls on them. I have a 2005 dodge caravan in my garage with all 4 calipers locked up. It is a good idea to replace the brake pads with the best ones and new rotors to
have someone pump up the brakes and hold to the floor open the bleeder on the caliper you changed when brake fluid comes out close. you might have to do this a few times until all air is out make sure you keep the brake fluid filled when doing it.
Line the bottom of the master cyclinder with paper and cloth.
Loose the master cyclinder cap
GENTLELY push the piston back.
the level of the brake fluid will rise on the master cyclinder.
Slip the pads in
Close up the master cyclinder
Do a quick clean up.
IF the rotor is in GOOD shape then you will not need to pull the caliper off.
The caliper is hold down by hex head bolts.
