I am not very car savvy so excuse my non-technical terms. I have to replace my front brake line in my 2000 Blazer and I can not seem to get the right fitting size. I have tried a PAE 330 and it fits in the top part but doesnt fit to the hose at the bottom. But a PA 230 fits the hose but not the top part. Are the fittings two different sizes? or am I just not doing something right?? Please Help

 

Hey Go out and buy an assortment of metric line wrenches from like 10mm to 18mm-that should cover your needs for this car! step66

 

I think you just answered your own question. They are indeed two different sizes. To get it to work properly, you really need to make your own line using the proper fitting at each end, then reflare one end.
