Stainless Steel Brake line Install
#1

I'm going to install stainless steel brake lines. Looked on the brake forum and don't see any details on how to do it. It would appear to be fairly easy and straightforward, but then again, not much is on these cars and just want to be sure.



What's the procedure -is it just a matter of taking old lines off and replacing with new ones (I'm buying the ones from Pelican here?)

Are the rears any different from the fronts?

When you take the old lines off, how much brake fluid comes out and do I need to do anything with the pedal to stop the flow?

Do I need to worry about too much fluid draining from the reservoir and affecting the clutch fluid hose; should I just clamp it off?



I have a motive bleeder and know how to bleed the brakes so not an issue when the lines are replaced.



Thanks

I think the RS Barn SS hoses (lines) are prefered. That's what we put on the track car and I'm also going to install them on my street car. Make sure you use a line wrench or you can damage the nuts. Are you changing the clutch (pressure) hose also? If not the clutch fluid will stay in the supply hose to the clutch master cylinder regardless of how low the brake master reservoir gets. Replacing all hoses is recommended as well as a complete system fluid flush at same time.

thanks for tip on line wrench. Clutch hose was replaced over the summer when it ballooned and pedal hit the floor. I'll check with RS Barn on the lines.

I have the RSB SS lines on the way as I have read too many time of other sets being "not quite right" when they arrive, I want a no fuss, done right solution. That being said don't forget to get either blue or amber brake fluid so that when you bleed your lines after changing the hoses you can just see the colour change at the nipple and know "your done".

the ones i got from paragon did fit the car and work fine, but i had to fabricate a retainer to keep the front ones from snagging things - the ones from rs barn are direct fit and need no modification - they just weren't available yet when i got mine or i would have gotten those instead

What's the price of the RS Barn SS brake lines? Website just says "call".

Also, as mentioned earlier, I would expect a substantial amount of brake fluid to leak out while these lines are replaced. What is your experience with that and any way to slow the loss? I do realize that the lines will need to be bled, but any tips on this?

they were pretty comparable as i recall



they make a mess - no way around it - but, you will be replacing the entire source of fluid anyway, so it's really moot



3 words though: MOTIVE POWER BLEEDER



p.s. - bleed the clutch while you're there - they use the same reservoir

Pete quoted me USD 89.00 for the brake lines but I was ordering a bunch of other stuff so there may or may not be considerations <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

I might be wrong here, but I thought if you push the brake pedal in slightly, maybe an inch, and hold it there with a stick, the fluid stops running. I have new clutch, master and slave, so don't need to bleed it again. Brake fluid is new as well, just need to replace lines and bleed as needed.



I ordered from Pelican, they have the set for $67 (DOT approved, $52 non-DOT).

if there is contamination in any of the cylinders, you need to flush and bleed the entire system, as it will find its way back to the reservoir and contaminate the rest of the system



this is why you need to flush and bleed the entire system every 2 years (it's even in the manual)

I installed the SS brake lines today (purchased from Pelican.) Overall, it's a pretty simple job. However, access to install the rears is a PIA. Between lying under the car, trying to manipulate two wrenches and the ABS wiring getting in the way, no picnic. The clips also are not easy to remove. Lots of cursing doing the rears, took 2.5 hours. Fronts are a piece of cake, 1/2 hr each max. What was also interesting is that the nuts on the hard lines are 7/16" as are all of my bleeder screws; don't know if that's news to anyone. Thus, my metric line wrenches didn't work. Bled the system, no leaks, all seems fine.



One other thing, if you use a stick to push and hold the brake pedal down 2-3 inches, only a few drops of brake fluid will come out.
