So I am having some brake problems as indicated in my other threads that may point to a master cylinder.

When you jack up the front of a 2000 2WD Dakota and spin the tires how much drag should there be on a properly setup brake system? Should they free-wheel? Should they take a small amount of force? Should they be tough to turn? Is there a specification for the amount of force required?

Thanks

 

I dont know about a particular amount of force, but you should be able to turn it relatively easily. Its not going to sit there and spin like the huge wheel on the price is right, but you should be able to turn it with your hand. if it "grabs" at a certain point your rotor is probably warped or something.

 

One issue often overlooked, even by pros in a shop, is that afed hoses tend to fail on the inside first and this tends to manifest as locking wheel, too much braking at this corner etc as the fluid cannot release backwards.

low cost first move I would suggest is replace the 3 flex lines (all 3, they were all installed at the same time and have all deteriorated at the same rate. Do 'em all while you can.)

 

I am not near my truck right now but I can't find in the manual or on the parts websites where there are three flex-hoses. Do you mean 3 per side for the front or 3-total for the entire vehicle? I already replaced the one that connects to the caliper on the front wheel in question.

Thanks

 

Had a problem like this on my truck my uncle told me it was prob the rubber brake line and once hot it was sucking shut. Next day went to autozone got a left front brake line and never had a problem. Then about 3 months ago I had a problem with the right front caliper and it was sticking so I replaced that and never had a problem with it.
