Question Asked: 

Sometimes, usualy on down hill braking the brake pedal will sink halfway to the floor and the left wheel will start smoking a lot for a minute or so and it will be hard to stop.There is a smell of burning brake fluid,but when i dissassembled the brake calipers i cant see any evidence of leaks although I do have to add fluid from time to time.Should i switch the calipers?I also switched brakes on another plymouth voyager and have the same problem ,Is there something about the brake system on this model. PLEASE HELP I LIVE ON A MOUNTAIN

Question Asked: 

I have a 1999 dodge grand caravan,3.3 liter, and so does a buddy of mine. both of them loose alot of coolant in city driving conditions,on the highway they dont seem loose any,it seems to be coming from around the radiator cap that is the only place i find evidence of water leakage,so i replaced the radiator cap and it improved but it still does it,i thought maybe the overflow tank line may be plugged but its clear,I cant find leaking anywhere else.ALSO IT IS NOT OVERHEATING OR HAVING A TEMPATURE RISE AT ALL even driving up a mountian Does anyone know of this problem

Question Asked: 

I m trying to find out were you can get test strips to check for a bad head gasket. they are suppose to tell you if there is exhaust emissions in the cooling system i have also seen some kind of tester that you draw fluid from the radiator to check for that.I dont know what there called or where to get them. Thanks for any help
