Need pic of front brake hose frame mount (1 Viewer)

[Steve Abbott]

I have a '65 40 with a '78 drivetrain that I'm upgrading the entire brake system on. It looks like there should be a mounting point somewhere on the frame for the front brake hose that runs from the frame to the front axle. My' 65 doesn't have anything on the front part of the frame to secure the brake hose. Can someone please post a pic of a later 40 that shows where the front brake hose mounts to the frame so I can get something fabbed up and put in the right location?
Thanks!

It's a junction block.....only pix i have, showing off the guard i was pleased to have found.

Thanks for that pic! I obviously had no idea it was a junction block. Is that guard a stock part?

Now that I know where it goes, does anyone have a pic of the junction block or a good description of what it looks like?

 

[cruisermatt]

the junction tee's are actually on top of the frame towards the firewall, and a short section of hard line comes out of that goes to the mounting tab on the side of the frame rail.

No need to fab anything, I already make those parts
We also have tons of OEM brake hoses hoses in stock, just let me know what length you need and we will have one that is long enough.

Toyota Brake Hose Mounting Tab

These mounting tabs are specifically designed for 17MM Toyota brake/clutch hoses found on all Toyota’s from the 70’s and newer. Perfect for relocating that brake line to clear an exhaust pipe, or replacing a original tab that got ripped off your axle housing. The mounting hole is 8MM so it can...

Your original brake line routing likely routed the front hard line up the driver side rail, dropped a take off to the driver side brake cylinders, and continues across the front of the bib, over and back to the passenger brake cylinders.

My 73 with drum brakes all around, had a duplex master cylinder. The front hard brake line drops down to the driver side rail and terminates in the clip shown above, and then a flex hose connects to a tee on the axle. The rigid line on the axle travels to both wheels, and short flex hoses connect to piping feeding the wheel cylinders in the front brakes. The second hard line to the rear brakes travels across the firewall, drops down to a 90 degree fitting bolted to the passenger rail, and a hard line goes from the fitting along the passenger rail to a flex hose connected to a tee on the rear axle.

Later FJ40 models have both front and rear brake lines travelling across the firewall to the passenger rail, and then connecting to the welded fitting shown above. Here again, the rear line supply is connected to the rear tee and goes back along the passenger rail. The front hard line connects to the front tee and travels forward to the clip shown above, then connected to a flex hose routed to the front axle.


I suppose you could adopt either of the latter two arrangements above. Length of hoses is dependent upon lift, axle travel and turning radius.

My late 70' 40 has front brakes as 73 described, hard line to just behind driver side shock tower, soft line to axle, hard line across axle.

I just went through this on my ‘67 a few months ago. If I had seen @cruisermatt ’s offerings, I would have gone that route instead of using generic 3 ways and unions that I needed to modify to work.


I matched the original routing, including wrapping the line around the front crossmember.

We also have a nice easy bracket for those H4 relays

I saw that the other day, but touché, ordered.

I’m not doing the 60 steering until I see what you come up with though!

Got you covered there too.

Here ya go! The muddy mess pics are how stk frt disc brake lines were run(76). The brakeline junction of @cruisermatt is similar to the stk ones. The stk ones
seem to be getting a bit harder to find. The red 40 is a 75, and the po installed a disc frt end. Originally, the po had the frt line dropped down from the master, coiled to frame then a rubber line to the 3 way junction on the axle. I changed it to be a more stk setup for stk disc. A stk frt disc frt end has the bracket on the housing for the junction.

If I were to do mine again, this is the routing I’d follow. These pictures are a great guide!

It’s more then similar, it’s an exact reproduction.

My apologies, i didnt mean to offend. I like it. I'm glad someone's making them.

I already have that double junction that mounts to the top of the frame. Based on your post, I guess there is a mounting tab on the frame, as I suspected, for the brake hose that runs to the top of the axle. Thanks for the link

Front brake hard line on driver's side showing bracket to flex hose. This is the OEM arrangement.

I am trying to mimic the '78 plumbing since I'm running' 78 axles. I have most of the plumbing completed but wasn't quite sure where the front hose connected to the line that runs down the frame to the rear axle. Looks like there is a bracket that I need to add to the passenger side frame behind the front axle.

Thanks for all of the pics! Do you have a pic of the other end of that rubber brake hose shown in your last photo? I think that's the last piece of the brake line puzzle for me.

Yes, there is a tab that bolts to one of the M8 holes on the frame. I have a 82 at the shop now I can take a pic of if I can remember.

I made the universal tabs since we run a lot of brake lines here , often relocating for V8 swaps/power steering/SOA and often the originals missing or rusty
