Nasieg 5 lug installed - tips/pearls

[diesekte]

An e30 SS line alone is too short to go from the e30 hard line to the caliper, since the hole on the e39 caliper is on the inner side instead of on the top like the e30 calipers.
Using the e39 line is barely too short - it connects but leaves a pretty acute bend in the line and has it under a bit of tension.

Maybe start looking at lines for other BMW's to see if you can find one that's the right length?

If not, you could probably make a few sets of custom ones and sell them here.

What would be the appropriate length?

I'll have to get measurements on the lines in a day or so.
I installed the 25mm master today, 34331156978, the e32 735il master that should work with the ix booster. It fits and works. I pulled it from an 89 e34 525i with an m20 - as per realoem it is the same part.
When I was at the yard I pulled the MC from a 91 e34 535i with an m50 for comparison - p/n 3431115711. These two look almost exactly the same. The piston that comes out the rear on both is the same bore and same length. The MC bodies are almost identical.
When I pulled the MC installed on my car by the previous owner, it looked a hell of a lot like 34311157111, down to the weird Arabic looking letter on the back and the "1043" marking http://www.ignacedewitte.com/zimages...re-frein-2.jpg
What's strange is to get to the above picture, I actually googled 34331156978.

To make a long story short, I switched my MC for a supposedly different, and definitely 25mm MC, and the pedal feel is exactly the same. I mean exactly. 2 inches or so of little to nothing, then almost full force braking from there on, with minimal if any transition zone. My only conclusion is the previous owner had installed a 25mm MC, and this is just how it feels with this kit. I have driven every iteration of the audi A6 since 2000, and they have all felt like this to me... Maybe it's normal with these components...

Something definitely seems off, you shouldn't have that much free play. Definitely see if the old master was a 25mm.

[diesekte]

Well I got it figured out. Finally.
The brake masters are both totally fine and both 25mm. The issue was with the brake booster. I removed the installed master to compare them and noticed the pushrod in the booster was pretty loose. I pretty much looked at it and it fell out, along with the metal retaining washer deal that keeps it in the plastic cup. I replaced with another ix booster and now I only have about 1.5" of pedal travel total, and am getting some brake action just a few mm in, instead of the 2" or so I used to have to push before they started working.

RIP old ix booster :/. Any rebuild kits available?

[mr2peak]

Really glad you discovered that before something bad happened!

Did you get the chance to take measurements for the rear lines? I am piecing this kit together now. Thanks

I just bought a set of these myself and it seems like the front offset will fall between the E30 and E36. I would love to run 17x8 et20 wheels up front, but I think the rotor spacer will make that a difficult task. I'd like to know if there are any other rotor or rotor/caliper setups we can run for the fronts that will help us get a little closer to E30 specs. I think the rotor spacer itself is 6mm so just doing away with that should be the ticket. Anyone experimented and found a setup that works without the rotor spacer?

This guy: http://www.r3vlimited.com/board/showthread.php?t=347702 used e28 wheel bearings with Mercedes w124 300mm rotors and e34 540i calipers with custom adapters.

How nice is the e46 zhp rack?

I have some of the rear lines that came with the e39 calipers I bought. I wondered if anyone who has installed this could determine how much additional length would be needed. In theory I could order longer lines with the correct fittings from Spiegler or another performance company.

Based on my deductions and research the line for the rear would need to be X length with a 710 and 514 fitting.

[Zekerbox]

If the OP on this thread could detail how much longer the e39 lines would need to be then getting a custom line made based on that would be fairly easy to do.

[Jb325is]

Im pretty sure I used e46 m3 front lines on mine. I will check when I get home though

[gtarwiz]

I can see how the E46 M3 front line could work, its got the length and is the same shape and the e39 rear line. Interesting.

I thought the lines had different fittings, as in I thought most cars after the e30 era used double flares. Do all bmws use bubble flaring?
