hi, my 2003 Dodge Grand Caravan SE van has 28K miles.. the brakes are acting wierd. there is like a hissing sound when I press them. also. if I am trying to stop from 40-50 mph. then i get a shudder.. or knocking.? I saw that the brake fliud level was less and i topped it off with an ounce or so. a bit of improvement but not much. Do I need a front brake job. or is something else wrong ?
also.. I just do regular oil changes myself and get tires rotated at Sams.. So what major maintainence do i need to get as I am close to
30K. .should I change the FUEL filter? should I change spark plugs? transmission fluid flush ?
Please advise.
vehicle is in S mid west so no snow or humid weather . ( Dallas)
