Problems with 2007 Chrysler Pacifica SERVICE BRAKES, HYDRAULIC

From the time the car was new when the abs or traction control was engaged the car made a clicking noise. as never having a car with this feature i thought was normal. in march of 2010 my brakes failed on my 07 pacifica. upon taking the car to the dealer i was informed that there was contaminated fluid in the brake system and the entire system had to be replaced. new calipers, abs module, lines, hoses master cylinder ect. the bill was $2500 which i had to pay because they are claiming contaminated fluid. i had been the only person to service the brakes on that car and did not add fluid when replacing the front pads. when the failure occurred the car would come to a stop and start rolling again. i avoided crashing by standing on the pedal as hard as i could. after replacing the entire brake system the clicking has stopped. i have driven chrysler/ dodge cars for 12 years... this one may be my last. *tr

Loud thumping sound when brakes are applied. sound seems to be coming from right rear brake. dealer has replaced slipper part # 5102476-aa,caliper # 5114440-aa,brake rotor #4721240-af and hub brake 4721354-ab. this has not solved the problem. dealer states they have requested help from chrysler on this problem but i have had no response from the dealer as of 02/20/2010. *tr

I believe there is a problem with chrysler pacificas abs system. i had a 2005 that after 7 attempts to correct the problem of the warning light staying on, chrysler took the car back. i now have a 2006 chrysler pacifica that has already been serviced once for the abs sensor being defective and it will be serviced again on thursday for the same reason. abs light stays lit. i have 18,000 miles on the 2006 and it will have been serviced twice for the same problem. it seems to me that this is an ongoing problem with this type of car. have you any data on this problem. *jb
