brake upgrade questions ,Chrysler master cylinder..

[awbrown]

It always worked normal so I thought it was OK , that being said I do need to replace the line from the master cylinder because it has 2 compression fittings in it and I also need a new rear brake hose because it is the wrong one and it has no mount . and the crimps have rusted away ,they look too thin for my liking..so it is kind of floating around ... Hopefully my son learned about adjusting brakes and maintainance .. I hope...
