brake lines and banjo bolts

So, I've installed the 13.2" Roush take-offs using Steve's brackets. Getting ready to fab up new hard brake lines in the 66 coupe. 

It occurs to me I have no idea what soft lines and fittings I need to connect the hard lines to the calipers. I am having zero luck finding out any information on the banjo bolt size. 

Anybody have any ideas on what lines and fittings I need? I was hoping I would just order up some generic soft lines and attach them with some banjo bolts and hook the hard line to them with generic flare fittings, but I'm feeling less confident and more confused.

Thanks,

Bob

Re: brake lines and banjo bolts

You have the right idea.  Banjo bolts are metric on the calipers, but a 3/8" banjo sized hose works great.  On the other end, you need a 3/8" SAE inverted flare, and a mount to the frame to hold it rigid.  (original mounts work fine if you move them).

I have toyed around with 70 Mustang disc brake hoses but have not actually gone so far as to bolt them on.  They are good because they use a banjo fitting and the frame end has a bracket made onto it.


Money you enjoy wasting is NOT wasted money... unless your wife finds out.

Re: brake lines and banjo bolts

Cool. So I'm on the right track. What size banjo, do you know? I.e. thread/length. I Cannot find anything that tells me. Do I have to go to Ford?

Thanks for the assist.

Re: brake lines and banjo bolts

They are metric, fine thread I believe.

Re: brake lines and banjo bolts

Just did the same thing with 2012 13.2" fronts and rears, MS brackets on a '66. I used these parts:

Front soft lines: http://www.jegs.com/i/JEGS-Performance-Products/555/635300/10002/-1?parentProductId=1682813 These worked perfectly and I did not have to relocate the line brackets. These come with the correct 10mm banjo ends and 10mm coarse thread bolts.

Rear soft line to axle 'T' fitting: http://www.jegs.com/i/JEGS-Performance-Products/555/635400/10002/-1?parentProductId=1682813 This only needed the hole for the axle vent through bolt to be very slightly clearanced with a 7/16" drill and works fine with a crush washer and dab of RTV to seal it to the axle housing. It has two 3/8"-24 inverted flare outputs.

Passenger rear soft line to caliper: http://www.jegs.com/i/JEGS-Performance-Products/555/635350/10002/-1?parentProductId=1682813 I welded one of the tabs included with the above listed front lines to the axle for the bracket mount end of this hose and ran a hard line from the 'T' over the axle as in the stock setup. You could also attach something like this to the axle with a large hose clamp: http://www.jegs.com/i/Russell/799/683942/10002/-1?parentProductId=1503601 You'll need a couple more crush washers as this hose doesn't include any - available at your local auto supply.

Driver rear soft line to caliper:

Adapter at 'T' fitting: http://www.jegs.com/i/JEGS-Performance-Products/555/100760/10002/-1?parentProductId=1149934

Hose: http://www.jegs.com/i/JEGS-Performance-Products/555/635504/10002/-1?parentProductId=1794732

At caliper: http://www.jegs.com/i/JEGS-Performance-Products/555/100742/10002/-1?parentProductId=1149934 This banjo adapter comes with a 10mm FINE thread bolt so you'll need a couple of these (one for passenger side rear, one for the driver side): http://www.jegs.com/i/JEGS-Performance-Products/555/100737/10002/-1?parentProductId=1149934 and you'll also want to get a couple more clips so you've got enough of everything to go around: http://www.jegs.com/i/JEGS-Performance-Products/555/63092/10002/-1?parentProductId=1317509

I also used this for hardline, like stainless won't corrode but much easier to work and flare. Shines up nicely and I like the black nuts. http://www.jegs.com/i/JEGS-Performance-Products/555/635800K/10002/-1?parentProductId=2111534 Wise to add: http://www.jegs.com/i/JEGS-Performance-Products/555/635810/10002/-1?parentProductId=2111534

Front lines installed:

Re: brake lines and banjo bolts

Nice write up McStang, I like your suspension too. What spring rate are you running?

Re: brake lines and banjo bolts

Awesome. Thanks. Now I know I need 10mmx1.5 banjo bolts. I like how you did everything with braided. I took Steve's suggestion and ordered the 70 mustang front soft lines, and I ordered a stock 66 mustang dual exhaust soft line for front to rear hardline to axle connection (and a vent hose kit). So, I'll have rubber on those. I have braided lines that came with the rear disc conversion. I ordered some coated steel hard line, so I think I'm good. Now I just have to fab up new hardlines to connect everything to the adjustable combo proportiioning valve and Hydroboost, and I'm good to go. I'll update this with progress.  

Thanks all.

Have fun Bob, nothing like the satisfaction of doing it yourself. Especially when it all works out!

Re: brake lines and banjo bolts

This writeup is awesome, any pics???
Why not use a rear caliper flex line that has the banjo fitting built-in, like shown for the front lines.
That would eliminate one extra adapter and the associated leak potential.

Don't seem to have taken any pics of the rear setup, will try to take some when I get a chance, just moved and life is a little chaotic right now. I could have used one of the front style lines on the passenger rear but I think they only had those JEGS lines in pairs - the driver rear is a 3/8" inverted flare at the axle hose so it wouldn't work on that side. They seem to be good lines and come with clear sleeving over the braided hose at a pretty good price. The hose ends and adapters on the back are all AN fittings, except for the passenger axle hose end which is a female 3/8' inverted flare with bracket mount end like the fronts and I don't see any reason to be worried about leaks. I've got about 500 miles on the system so far and will be keeping an eye on it.

Re: brake lines and banjo bolts

Hi there, this information is very helpful!, the question I have is, why not use the same set of hoses from the front calipers in the rear?? (=18pxJEGS Performance Products 635300 DOT Brake Hose Kit)

Re: brake lines and banjo bolts

Be careful on hoses.  I like to use only the length required for that particular car.  McStang's installation is a good example of why I do not supply the hoses.  The ones he used are quite long and, while they may work perfect with his aftermarket coilover suspension, they might NOT be what you want if you have stock type upper control arms.  I suggest using a 1/8" rubber vacuum hose to mock up the lines and see what length you need for your particular application.

If you know the end fitting spec, you can call one of the brakeline companies.  They can make a line for you in no time and get back in a couple of days.  Cheap too.

Re: brake lines and banjo bolts

These hoses have worked out for me although if I wanted to spend a little more money the fronts could be a little shorter, maybe 16" instead of 18", but I've turned them slightly inboard at the caliper since that pic was taken and they don't come too close to anything throughout the whole range of suspension travel. I agree though that using a piece of vacuum hose or something similar with the front springs removed so you can move everything through the full range of possible travel would be a good way to figure out what works for your setup. I found that the hoses I used, with the chassis brackets in the factory location, worked just fine. I've put about 5000 miles on this brake system now and it works really frickin' well. Thanks to MS for figuring out the hard stuff.
