I put a new rear end in my car and ran some new metal brake lines on it to some drag brakes. My problem is going from the stock body brake line to the 3 an fitting on the rear end. I can either go from the stock body brake line to a braded line then to the 3 an or I can keep the stock rubber line going from the body brake like to the "t" adapter on the stock rear end brake lines but instead of going to the stock "T" adapter I need to go to a 3an. I'm sure someone else has fought this and know the fitting size that i need an adaptor for. I hope I didn't confuse everyone because I kinda confused myself.

 

I have all the flaring tools 45* 37* and a bubble flaring kit it makes it so much easier....

I would say the easiest thing to do is take the stock line, I think its 6mm going to the back and use a 45* nut and adapter and run a -3 braided line to the rear. Or depending on what you ran along the axle tubes, I have gotten a f-150 line with 1/4 on one end of the hose and 2 3/16" on the t part and made that work.

Just get creative

 

Helpful hint..... "LT1 Based Engine Tech" is not for brake topics. Moving to "Suspension, Chassis and Brakes".
