Brake Line Question
Is there 6 rubber lines on our cars? 1 at each corner obviousy and 2 near the pumpkin? About to order an SS line kit and some kits say "comes with 4 lines" and other kits show a picture of 6 lines.

Yes there are a total of 6 total. Some people dont run all six. I bough the stoptech kit which came with 6 and did not install the two inner ones.

I put the four-line Stoptech kit on my car and was happy with it. Happy enough that when I put the AP Racing BBK on, I didn't see any point in installing the short lines on the rear subframe, so I left them stock. The AP kit comes with a six-line Goodridge set, and I never had any concerns about only using four.

Why wait for a "pro" to answer? I think the answer is pretty simple. It's a system, so you've now left the 2 small lines as the "weak" links. However, if you leave them as they are and replace everything else with stronger lines, then the amount of volume increase (something undersired) due to expansion in diameter of the line when under pressure will be reduced. Whether that reduction is sufficient, or whether that reduction would be significantly better with the 2 lines replaced depends on multiple variables, including the condition of your lines, your sensitivty in feel, to the temperature in the system at various locations (e.g. at the piston), the fluid, the age and condition of the fluid, etc.

to be honest, i wont worry about it too much. the important brake lines (ie fronts) will be completely stainless steel already. the ones that arent changed are 2 very short sections in the back. i doubt you will be able to feel much of a difference since the back doesnt do most of the braking anyway. i say just go for the 4 line kit and call it a day.
by the way, when i took out the oem rubber lines, they are Very thick and look to be very durable. they arent just regular brake lines that i've seen in other regular street cars.

The Stoptech SS Lines now come with 6 lines. I believe a couple years ago they sold them with only 4.
I got 6 lines in my kit but only put on 4 lines as well. At first I thought they sent me 2 extra on accident but when I found out they were the for 2 small lines in the back I didn't even bother to install them. |

hey guys. new to the forum. just picked up an 08 e90. love the car, but one of the biggest issues i have with it aside from the lack of feel from the clutch pedal, is the squishy feeling of the brakes.
any difference or preference on stoptech vs challenge SS lines? Looking to get a set ASAP. thanks
