SERVICE BRAKES, HYDRAULIC Recall for 2002DODGECARAVAN
Recall Announced MARCH 13 2006
NHTSA Reference #06E022000
Number Affected 7,440
Summary: Certain aftermarket brake hydraulic
master cylinders sold as replacement brake cylinders for certain Ford,
DaimlerChrysler, and Jeep passenger vehicles. These brake cylinders
were sold under the brand names of Napa, raybestos, aimco, ac delco,
Carquest, bendix, and wagner. Only products that were manufactured from
July 27, 2005 through January 17, 2006 (date codes 0529 through 0602)
are subject to this recall. When subject to very cold temperatures, an
internal seal in the master cylinder could lose flexibility and may
cause brake fluid to leak. Consequence: Loss of brake fluid can lead to a
decrease in brake line pressure and an increase in stopping distance,
which can result in a vehicle crash. Fix: Affinia (brake parts, Inc.) will replace the
subject brake hydraulic master cylinders free of charge. The recall
began on March 20, 2006. Owners can contact affina group customer
service at 1-800-323-0354.

On the bad ABS system we have on our cars, sometimes the brake fluid pump gets stuck. On top of the transmission is a big rectangular block that is connected to the master cylinder by two big hoses. If the pump gets stuck you can put a metal pipe up against it and tap on the other end of the pipe with a hammer. If you do this with the car running you can sometimes get the ABS pump to fire up again and after a couple of stops the ABS light will go out. You will know if the pump stops working because the brake pedal will get hard and you will not be able to stop easily with both feet on the pedal. When my last pump died, I took off the old one (it is held on by one bolt), unhooked the two hoses from the master cylinder, bolted in a used one from the salvage yard that cost $20, and bled the brake system following the instructions printed on the brake fluid reservoir.
Abs system cannot permit air to enter the hydraulic system, You need to check everything for leaks. Likely you have slight seepage somewhere, likely at or in a line going to the wheel you found you had air again. Leak does not have to be large and at this point likely is leaving only damp residue. If air was in the front, also check inside the caliper piston boot....If at rear, check for dampness under the wheel cylinder end boots.
Below the Brake Master Cylinder and slightly back towards the Fire Wall. Should have multiple brake lines running into it.
Hint: Most people want to replace these. Alot of times the connections are merely corroded or have build up on the conductors or in the conductor "pits". Clean both and check before going to the expense of replacing. I did and it worked and saved me $$ not having to replace.
