Yes, I've got a d95 <Monte Carlo> and I just replaced the Master Cylinder , Re-Connected the brake lines to the Master Cylinder , and went to go start pumping the brakes there is 4 lines aall but one , so 3 of the lines where it connects to the master cylinder is leaking through the Fiittings of the line where it threads into the master cylinder...

What is my issue here Ive got going on and solution to my problems I am having.. Id gladly appreciate and opions or things I should double check or do to fix this problemb so I can move on and fix other minor problems this car is having..

Thanks...

 

Like all fittings, you may need a sealer for the threads when you install them with plumbing fittings there is a tape. Check your auto parts specialist and see what they may have for you application.

 

As in Teflon Tape or should I buy some type of Spray on Sealer..

 

It is best to check with you auto parts store and see what they recommend stuff for the house may not work in the Heat conditions under the hood.

 

There is a current thread closely related to your question on the forum. It is about "bubble flares" on the brake lines, and how the book says you must use new lines when you open separate them from the adjacent mating surface. Most of us get lucky and can get away with reinstalling the existing ones to the new fitting. Sounds like all the pressure from your new master is wrecking havoc on your connections. I would inspect them, they may be slightly deformed from the old surface contours and the new ones being slightly different. You can get a brake line flaring tool and use it to reshape the flared female cavity. Just bump it enough to tweak the metal surface into a true shape. Then clean everything, reinstall the line, snugly tighten the fittings, but not so much as to over tighten and potentially create a new leak.

 

Thanx for the suggestions everyone.. I figured it out used white teflon tape got the brakes bled and hve stiff petal... Now on to the next few minor things I need to get done to make it road ready
