DIY: Challenge Stainless Steel Brake Lines

djpathfinder · 03-29-2012, 02:25 PM

How many times did you repeat the process on each side (inside and outside)? Sometimes you need to do it lots of times before you see no more bubbles in the tube.

You may just have a lot of air in the lines...especially if you're doing the rear calipers. The best $60 you may ever spend is on a Motive Power brake bleeder. Makes the chore of bleeding a mindless one-man job.

I second the need for a 10mm flare wrench. I've rounded all kinds of the hardlines and I've since ordered new hardlines for my next brake bleed (only about $40). Do yourself a favor and go get a 10mm flare from Autozone before you round all the 10mm fittings.

Did it about a dozen times each caliper. No air now, but pedal feels soft. I installed stoptech lines, anyone have experience with them?

M.Bonanni · 03-29-2012, 04:22 PM

Hmmm wierd. Maybe some air in the ABS system? Usually you want to bleed the inner valve first, then the outer.

eagleeye · 03-29-2012, 04:57 PM

Yeah, tried inner valve first, outer valve first, and both at the same time. Went through 3.5 bottles of motul for the install and the two times bleeding the brakes. At this point I think I need to schedule an appointment with nissan...

Dumb question Eagle...you DID do both bleeder valves on each caliper, right?

eagleeye · 03-29-2012, 07:45 PM

On both fronts, yes.

There are 2 on the rear, also.

You can see it in this pic, barely, on the bottom right of the bottom caliper, and also the top right.

Didn't see a 2nd bleeder on the rears, gonna take another look...

eagleeye · 03-29-2012, 11:17 PM

gonna do another (3rd) bleed tomorrow and hopefully that's a wrap.
Thanks for pointing this out MightyBobo!

You wouldnt be the first to miss it. Hope it fixes your problems!

eagleeye · 03-30-2012, 04:14 PM

It was the 2nd bleeder valve on the rear calipers. The brakes feel so much better now. Thanks again guys, good DIY Bonanni.

Glad you got the problem solved!

I've always been leary about doing this myself... I have done every other mod to my car myself, it's just something about working on the brakes that worries me. Maybe I'll work up the nerve to try it some day.

Why worry? Brakes only slow you down!
