which is the pressure line and which is the return line? top or bottom?

RobD

There is no "pressure" or "return" line, per se.

Make sure you read up on the difference between LSPV and LSPBV. There is a difference.

i replaced both lines to the rear but affraid i mixed them up, with my abs (all wheel) it has a return line i guess from the rear that t's the pressure line to the front wheels under the master cylinder, the other "pressure" line i guess it would be comes strait out of the ABS to the rear. but i dont remember which line was which. and i'm having problems after fixing the broken line. i'm only getting brakes in the rear and i cant get the air out of the system ( mushy pedal)

Truth be told, I pulled the LSPBV out and ran one line off the front to the back and blocked the other from the front.

Upside, I have way better brakes than I did before.

Potential downside, the back end could try to outrun the front under heavy braking. I haven't had any problems yet, with the rear ABS keeping the back end in check.
