cautionary tale; almost hit 'em

Its summer and most days have been great for driving the 3b around. The other day my 15 year old daughter and I took off for the end of the road, about a 10 mile one way trip from the house. We were going to a deserted beach where she could drive around slowly and practice using the clutch. We could not have been happier as much of the road is shaded and curvy with great views and a 35 mph speed limit. When our tourist friends, who are often in a hurry to see all the sights on the Island, piled up behind us we would pull over and let them pass. Almost at the end of the road, a rent a car pulled out in front of us suddenly and a panic application of all 200 pounds plus of my body weight on the brake pedal kept us from t-boning the visitors. The pressure was too much for the brake system and a catastrophic leak occurred in the line. I am so thankful that the line held until we stopped and then fluid squirted all over the place. I called my wife and she came to pull us home with the pick-up truck. I simply haven't taken proper time to address many of the seemingly small problems that want attention on the jeep. When we rebuilt the brakes, foolishly, I did not change to brake lines at the same time. I did not hook up the emergency brake. Just kept having fun. And it almost cost us. Big time. So, what I want to share is, be safe not sorry. Stupid is as stupid does. At least it was a good move to mount the tow bar. Hope none of you have any close calls to report.

i love posts like this, thank you mrbob and so glad your ok and wanting to help others

i too almost totalled my 3B and luckly escaped personal injury due to a brakeline
that decided to crack at flare where it goes into master cyl and my parking brake didnt have enough grab to stop me ...

the younger gen getting into vintage metal please realize there is no failsafe if you
spring a leak - check your brakes - your ebrake ( parking ) is x10 more important
so make sure it works !!

Hey guys, there is reason that the automobile industry replaced the single master cylinder on almost everything in the early 60's or was it the 70's, it was because if a brake system has a failure you are in trouble.

A dual master cylinder, even if you do nothing else will and can save your life. I could not see going on trail rides in the Northwest or even Moab without an adequite brake system, including a working e-brake.

I have up-graded my 54' 3B with a dual system from a 85' cherokee with hanging pedals, it may not look like it came off of the assembly line in 54' but it stops and I can loose front or rear brakes and still have two brakes to stop me.

The 1968 to 1971 CJ-5 step bore type of master cylinder is a very stock looking modification for the 3B.
The CJ-5 split cylinder and its brackets are a direct bolt in for CJ-3B.

MrBob - I'm so glad that you and your daughter are safe. One of my first times out with my jeep after it was "done" I had someone pull right out in front of me - like I was invisible. Well, luckily the stock brakes were freshly redone, to include new lines and I locked them up on dry pavement moving about 25-30 MPH.

Our jeeps are tiny compared to most other vehicles on the road these days. Things are moving so fast and people are so preoccupied with other stuff that sometimes they just don't see us. I also found out that the jeep is so short that it fits nicely (if that's the term you want to use) into another vehicle's blind spot. That is someplace you do not want to fool around - stay back or get around them.

I hope it's not long before you're out enjoying your jeep again.

Started to size and flare new brake lines but will instead go the dual master cylinder route. And get the emergency brake set up. Thanks for the feedback. No more fooling around.

Glad to hear your okay, I recommend everyone should replace all brake lines as one of the first mods to their jeep to prevent such an occurance.

Thanks for starting this thread. Just now rebuilding my brakes and your warning has prompted my to replace all lines. Thanks again.

I am running original brake tubing on my CJ's with zero problems.
Each tube was externally inspected then internally cleaned out with alcohol and pipe cleaners attached to piano wire.
I switched all systems to DOT 5 .

Another reason for upgrades like 11inch brakes with a E-brake for back up,,Ive got a 64 Cj-5 that had the master Cyl rebuilt just 3 weeks before buy a repair shop,, The fellow I bought it from didnt want to foot the bill of a new Master Cyl,, I was plowing my down hill lane with her & the master Cyl let loss ,, I pulled the Hill hugger & dropped my plow as there is a 20 ft drop off at the bottom,,I stoped about 6 inchs away from going over the edge,,, Sure its not stock any more but it could save someones life ..

When I restore my 64,, 11inch brakes & duel master Cyl are first on my list to replace,, Streetrod parts have been making a situp that fits under the bodys of different rods & the pedels come up though the floor,, Like the stock 3bs,,

THIS WHAT I PLAN ON PUTTING ON MY 64 CJ5 ,,,

If you are trying to keep the stock appearence, why not just go with one of Herm's dual masters and keep your stock pedal?

ALSO adding Herm's Dual Master Cylinder to my rebuild. What's recommended for new Brake tubes: Should they be painted or left natural?

i paint mine and plan on coating them with axle grease. there is a new type of line out called ez bend, i believe it is some sort of copper composite or something. anyways i am to cheap for the fancy stuff, on a side note you might want to check out the overdrive giy, he has some pretty neat banjo fittings for the dual reservoir swap.
