why do i even need the 6th line, or the 5th??? what are they for

 

Ok..... installed it.... and installed the speed bleeders too.

Make sure you reuse the copper o rings when installing the new braided steel lines to the caliper!

The first one I did..... leaked.... until I removed it and put back the copper o ring... then no leaking.

Use LOTS of WD40/ penetrating lube.

Use flare wrenches for the brake lines... don't just use a regular wrench.

I installed the speed bleeders at the same time and it went perfect!

I installed all four lines to calipers.... but ran out of time for the center one to the distribution block near the rear.

Immediate difference! Pedal feel... braking etc.

Keep in mind.... my rubber lines had 95,000 miles on them!

Went to track already..... now the bird's brakes hold on a stalled launch!

Much happier!

 

Here's the info I have collected on braided lines:

I've heard some people can feel a difference, some can't. I really don't know if I should get them or not. Can anyone give more feedback on the differences? Such as pedal travel, firmness, braking differences, etc... I'd really appreciate it.

Jason, I never could honestly feel a difference.

Some claim a huge difference and I bet it's more the fresh brake fluid rather than line flex ...

 

I built a pressure bleeder and switched the factory 1999 fluid over to ATE Super Blue. I didn't have any visable air in the lines, but it did make a difference in feel. It was a little firmer, which is good. I'm not sure I could get the pedal any firmer with steel lines, plus you invite air into the system by changing them out. I just don't know if it is worth the potential risk to change mine. I'm going to wait until I get my new brakes broken in to decide if it is worth it or not.

Hey Mitch, can you check this thread and offer any advice on bedding in new brakes?

Surely you must have the technique down pat, right?

 

Fresh fluid along with a GOOD bleed makes a big difference. SS lines vs. new rubber lines = tiny difference. SS lines vs. old rubber lines = big difference plus will stay feeling that way. SS lines will also keep water out of the brake fluid longer. Brake fluid attracts moisture so strongly that it actually soaks through rubber lines. Will take much longer through SS. Ss vs. rubber - small difference when all new, when old - difference is huge. Hope that helps.

 

I've heard that there can be a difference between new rubber and the SS lines under race conditions. The increased heat and hence, hotter brake fluid can cause the rubber lines to be heated as well causing them to stretch a bit more easily. The SS lines are supposed to use teflon liners which flex less when heated. I don't know if it is true, but I felt it worthy of mentioning.

Another thing I heard is that SS lines should be covered with a rubber protective sheath to keep then clean. If a small speck of dirt or sand gets into the SS braid it can rub against the teflon liner and possibly wear a hole in it. That would be catastrophic. Again, I don't know if it is true, but I felt it worthy of mentioning.

 

Wish I would have caught this thread earlier. ABS needs a 5 line kit and the TCS needs a 6 line kit. I have a 6 line set from Techna-fit that was custom made for my Corvette front brakes.
