I hope it happened in the driveway! 

Wow, you and the car ok? clean your shorts out and give us the details!!

I seem to recall David Friedburger who used to be editor for Car Craft (and a couple other magazines IIRC, and now host that show Road Kill on Velocity) saying once that you either need functional brakes or a manual transmission and a horn. 

I drove my '76 CJ5 with no brakes around the farm for years.  In 4 low, with 3.15:1 gear reduction in the transfer case, plus the 3.54:1 axle ratio, and 1st gear in the 3 speed (probably a 3.xx or so; not a granny low by any means) it would just creep along, and even maxed out in 3rd gear it was probably only running maybe 35MPH.  I could just downshift, and eventually double clutch it into reverse and by slowly letting out the clutch I could stop the thing on a dime, so long as I had enough room to plan for it. 

I lost hydraulics in my '06 F250 once.  One of the rear calipers got hung up when one of the slide pins stopped sliding.  I couldn't even hear it over the Diesel, and it ground about halfway through the metal part of the inner brake pad until it got so thin it slipped out of the caliper mount and the pistons made contact with the rotor (they were unable to stop the truck unfortunately).  The pistons got cocked in their bores and it started puking fluid.  I drove from Rising Sun, MD back to Newark, DE (about 35 miles) with no hydraulic brakes.  I stuck the transmission in Tow/Haul to use compression braking, and then would ease into the e-brake if needed.  Fortunately it was late at night and there were few cars on the road.  I got home without incident. 

The scariest time it happened I was about 16 or 17 and had converted my '67 to power front disc brakes.  I couldn't get the manual brake pedal to work, so I bent up a pushrod extender.  I stepped on the brakes one time too many; it bent and there went the brakes.  Fortunately I was less than 2 miles from home on back roads.  We both got there fine.  No internet at the time to quickly tell me that the pedals are different between manual and power brakes.  Nothing about it in the instructions from SSBC either.  Made a half dozen calls to figure it out, swapped the pedal and problem solved, but the prospect of wrecking that car was pretty damn terrifying. 

Hopefully you and your ride are both okay 6sally6. 

30 years ago I was driving a 2 ton IH dump loaded with sand. Came to a stop sign, stepped on the brake and the lines busted. I started grabbing a lot of gears. Luckily no traffic at that moment and I made the turn without rolling. A lot of pucker factor involved there.

Naaaaaaaaaaaaa. parked it. Something even more major popped up!
Never dull in "sally-ville"!
I'll just say...thank the Lord for a manual tranny----- and living in a flat area! (didn't even need the horn)!!!

mine went out one day on the highway here with the wife in the car. It was a humling feeling. Thankfully it was late at night and not many on the highway.. oh man!!! you are right Sally what a feeling!!!! LOL

Made me upgrade things quickly! LOL
 

Not to say you would ever do it, Sal, but using the cheapest components you can find for your brake system is never a good idea!!!

Well...........now that the "suspenders" has built, I can finally tell how it all went down.  (like-the-brake-pedal on-a-souped-up-Mustang)

"It was hot in the city....I was working the day watch out of robbery.....this is my partner Frank Smith..........my names Friday."         Dine-Da-Dine-Dine.

OH ...worng story!!
Anyway...after sitting up for over a month(weather/out-of-town)..finally had a nice evening...opened up the headers and fired the old hot rod up for a cruise. Stopped a few times......ripped thru the first couple of gears----a few times...everything seemed OK
Rode up the beach to.... "cruise-the-boulevard". When I  applied the brakes .....................I heard that un-nerving thump we all have learned to dread.  The THUMP of my brake pedal  as it smacked  the well padded carpet!!
Made a quick "U-E" and limped back home.
Now...we are in the height of tourist season  here and surprisingly enough....nobody "cut-in-front-of-me"...and slammed on their brakes (Gosh I love THAT!) Timed all half dozen or so traffic lights so I could roll through on green.
I needed to make one left-hand turn across traffic and was able to stop by killing the ignition while in first gear.
           Hey...what can I say...God looks out for me!! ....He LIKES ME!!
Thank goodness for manual trannys.
Looks like I ruptured the rear brake line right above the third member. It's only 52 years old....you would think stuff would hold up a little better butt.....
Strange thang is....my front discsezz shoulda still worked and stopped me ...butt they didn't.
As one somewhat famous brake expert sez....."theoretically".....the front disc should have still stopped you........theoretically............OK.
Rear bowl was full(MC) of fluid butt of course the front bowl was 3/4 empty. Master cylinder COULD have "taken-a-dump" the same time the rear brake line let go.
"Theoretically"..... that's nearly impossible butt.....looks like it mighta happened to old Sal.
The fix will be to replace brake lines from rear to MC.....May replace MC...... WYAIT. 
It's a good time to replace that rubber hose that connects the rear line with the line going down the tunnel. 
Need to use the looong hose(how MANY times have I said that!!?) Since I have dual exhaust.
  What......hose off a 69 is longer than the 66,....right?! 
Dead line is to get it right before BulletBob and Rudi come to the beach!!!!

Well Sal, Bob or I might want to ride along if we can have an anchor on our lap to toss out.

Someone was asking about a six cylinder engine on a thread here a little while ago, maybe its still available?

Well Sal, as your good buddy, I’m gonna give you some tough love. The front brakes SHOULD have stopped you! The front brakes should be doing most of the work. You really need to find out why they didn’t work. Maybe the pistons are stuck in the front calipers. Nobody wants your new paint wrinkled.
