Front Brake Line

[Mike07SE]

Need help on the front brake hard line that goes from the caliper to the flex line. I was installing my RR Racing BBK today and could not get this fitting to not weep between the flare nut and the hard line. I'm sure at this point the tubing flare is worn out after multiple brake jobs and this was the final straw.

I cannot find the PN that is this hard line from the caliper. Most diagrams that the I'm able to pull up reference the flex line which I do not need (upgrading to SS lines).

I also came across this from Wheeler's Offroad for Tacoma's.

Any thoughts on these lines working? This would convert from a flare fitting to a banjo. I don't see why it wouldn't work as long as the threading is the same. Plus, this would also work easier with the line input on the Wilwood caliper being in a different location and orientation than that of the OEM caliper.

Wait,so the stainless hoses pictured on RR's website doesn't replace the existing hard lines to the OEM calipers?
In my last brake job I used some pre-made straight line with the correct fittings on both ends, then bent them myself. I'll post an update when I find the part # for the line.

UPDATE
Poly-Armour brand https://agscompany.com/product/japanese-poly-armour-pvf-steel-brake-line-3-16-x-8
$3.99 at Advance Auto Parts,but they have 20-25% discount codes popping up recently if you order online for store pickup. It's slightly longer than stock, it think some people here used a shorter line but I wanted to play it safe.

I thought the lines that came with the kit replaced the hard line and went straight from the caliper to the hard line up by the shock tower. That is what the Stoptech one does as they use different banjo fittings into the caliper.

Now that you two have said it, I looked at the picture for the kit and those lines look like exactly what I need and pretty much what I was referencing to with the link to the Wheelers Tacoma lines. I took it that these lines in the picture were the upgraded SS flex lines that I optioned for when purchasing the kit.

I'll be calling RR today to straighten this out.

I recently did a brake overhaul and snapped one of these lines. I also already have the braided flex lines that come after them. I was able to match the fitting size and just bend a new brake line into place. However after digging, these are the part numbers I came up with that work.

Ive also read on the tacoma lines with banjo fittings. If anyone has a specific link or part number for those to replace these stupid hard lines that would be helpful.

Thanks Ed & Billy for those responses, they were really helpful.

As I'm working out the kinks of this BBK install, I'm going to have to make my own new custom bended lines to replace the OEM hard lines from the caliper. Right now the BBK is on and working well. I was able to resolve the weeping brake line as it was an issue with the caliper fitting adapter (assembled by selling vendor with wrong fitting). The OEM caliper hard line is currently not mounted to the spindle bracket as it cannot reach it. I could leave it setup the way it is but rather do this extra step to play it safe.

This Poly-Armour tubing looks nice and should fit the bill. Now I need a new brake line flaring tool kit and bender in case I need to trim it.

For others to reference, it looks like the lines are 3/16" hard lines with M10-1 double flare / Inverted flare nuts (not bubble).

Once I get all of this finalized I'll have a write-up of this install saga.

Glad to help.

So the pictured brake braided brake lines replace the OEM rubber hoses from the frame rail to the OEM hard line? I see banjo fittings so I assumed those lines replaced the OEM hard line.

I wouldn't cut the Poly-Armour tubing, just bend it to shorten like OEM

 

[Mike07SE]

Nope. Those SS Banjo lines are not included in this kit. Must be a stock photo that they used - confusing, I know. I opted for the SS lines when I purchased to replace the OEM flex lines assuming it would work in addition to these pictured.

Basically all you are going to get are the calipers, brake hard line adapters, pads, and mounting brackets. Rotors, SS Lines, and anything else are extra options.

You definately want to get the brake line mounted back to the spindle ASAP, on mine the bolt head broke off at some point, I had the tire off
a few days prior and the bolt was fine then and when I saw it was just hanging I was thinking "it's a metal line so it will be fine"...well not
long afterwards (about 3 days) the metal line broke right where the fitting goes into the caliper, just the little bit of the metal line flexing
everytime the wheel was turned cause it to break, brake pedal goes to the floor, really bad part is it was Thankgivings day 8:00 at night and I
was 90 miles from home and no autoparts stores opened.

I ended up driving all the way home down shifting to slow down and using the parking brake to stop when I had too, the only good thing was
there wasn't very much traffic on the road so I made it home safely.

 

[Mike07SE]

Thanks for that feedback. Truck is luckily not a daily driver so I will ground it until I replace the lines to mount back to the bracket.

WHAT? No way. Those HAVE to be included and may have been just left out of the box. What did RR say? I can't believe they wouldn't give you new lines. The Stoptech kit has all new lines with banjos on the back of the caliper, then the line goes up thru the spindle hole and their line has a guiding connector you use the slip ring on and then it goes directly to the fitting near the frame. I can't believe they would sell a kit and not include those. I'd return it and get Stoptech from SOS Performance before making my own lines on a BBK.

 

[Mike07SE]

Oh believe me, if I could give this back to them and start over with the SOS Performance Stoptech kit I would. And I still may down the road.

I'm still not done dealing with RR Racing. Hasn't been a very good experience with them so far. I was going to wait until my saga with them was over to document all that I went through.

Dude...if it's not a daily...I would rip that out and send it back. Tom at SOS Performance was AWESOME to deal with and I'm sure he could get a set sent to you ASAP. And no, didn't get any IG hookup or whatever. Paid full sale price but his communication was top notch. Used Stoptechs on all my Audi track cars and why I went with them. But those calipers you got should have come with new lines. I've never heard of a kit not. Sucks about what you're going thru.

 

[Mike07SE]

I'd switch out, but at this point I feel like I'm SOL with the $$$.

Hope RR gives you some kind of reimbursement or at least a discount for whatever parts you need to get over this brake line saga.

Maybe the following info and suggestions can help...

I did some searching and the Aero6 calipers use a 1/8-27 NPT thread for the inlet (according to this https://www.wilwood.com/LineKits/LineKitsProd?itemno=220-13912 ), pretty odd for a caliper fitting, usually find those on carburetors and sender/sensor ports on engines.

I'd ask Wheelers what's the length of the Tacoma stainless lines you posted before, specifically the section from that bracket to the caliper end (although judging by the photo it appears you can slide the bracket). Use some string to get an idea what length you'll need. I don't think you can use them on the Wilwoods because of that NPT inlet, not even Wilwood themselves offers a banjo with a 1/8" NPT thread. If they build those in-house maybe they can swap the banjo end with a 3AN, then a 45 deg (90 might be too tight) NPT-AN adapter into the caliper.

 

[Mike07SE]

Thanks for digging that up. I was meaning to get to that and find out what it could be. My original assumption was that it would be a 3AN or NPT fitting, but oddly it's not by your finding.

I'll keep things posted.

Dang man. I remember when I was missing my front banjo lines for the ST40 kit a few years ago. Original owner lost it and didn't let me know so I was delayed waiting for the new line to come in.

Thanks for your advice and input. Finally got around to redoing the lines with the Poly Armour PAJ-308 8" lines. Everything worked out great.

I think at this point I feel like the project is done.

I like your setup a bit more since you get to use the stock mounting point. This is how the line is setup for my st40 kit. One long as line from the caliper to the upper hard line.

Glad you got it figured out! Did you cut and re-flare the new line? Looks shorter than 8"

RR recently emailed me asking if I plan to order their kit, I held off emailing back until your saga was over. Not that I need to replace my fronts but I'm going to tell them no after the lack of support they gave you.
