    Two suggestions of varying work: 1)snubbers to limit vertical axle movement to just shy of bellcrank interference. 2)Make radius rods and install to greatly limit axle housing rotation. Possibly re-arch the front springs or beef them up to increase clearance, while at the same time adding resistance to axle housing rotation. Think about rear wheel drive hot rods, helping eliminate wheel hop and "ladder tracks" under very hard acceleration. Back in the sixties, with the advent of muscle cars, we tried everything from "slapper bars" and ladder bars, to spring leaf strapping, and offset shock mounting.

    Front tires that are completely locked up lose the ability to steer, a car will continue in the direction that it was going before the brakes locked. I learned that driving on ice a long time ago, when driving on ice, when you hit the brakes even the slightest bit, the front wheels almost instantly lock up (without anti lock brakes), front wheels lock up you have no control with steering, let off the brakes and steering returns. There are lots of ways to kill yourself with an old jeep, they roll over easily and no roll bar or seat belts, also in a bad front end crash the steering shaft tends to go right through the drivers chest, a common problem in older cars.

    I think the idea behind the lose grip theory only works at higher speeds, the faster an object moves the less it "wants" to change direction. I have ridden many miles and never experienced the problem, bu it might have something to do with with bad brakes and possibly a natural instinct to just "fight it", i don't know, but i've had my share of "emergency stops". Keep up the good work educating people about the Willys jeep that helped win the war and started the making of vehicles that to day just go by the name of Jeeps (no matter who's the maker) and the SUVs. Cheers from Norway!

    Ford Motor Company referred to this phenomenon as recession steering. It is caused by the relationship between the front suspension and the steering. One of their models suffered from this in the late 1990's early 2000's I think it may have been the F-150.

    All single hydraulic brake systems have equal pressure in all the lines at the wheel cylinder. They all work on a form of mechanical advantage. As long as there is no air in the system, a hydraulic line that's 6 inches Long in parallel with a hydraulic line that's 10 feet long have the same PSI at the end of the line. Back in the old days the lines used to swell, which would account for pressure differences amongst lengths. Nowadays with new brake lines not so much, especially if you have steel braided brake lines. In order for the length of line to be the main difference; hydraulic fluid would have to be compressible, this would account for the different pressure rates over length of hydraulic line. But that is a physical impossibility. Hydraulic fluid is uncompressible. This is what makes hydraulics work in the first place. This is also why hydrolocking an engine will break Pistons and Rods. Your engine is trying to compress a liquid which is impossible so something else has to give way. The old school hot rodders did that trick not because of pressure differences in lengths of line due to hydraulic pressure, but mainly due to stretch of line material. Now I went and just looked at the diagram of this Jeeps breaking system and there's not that big of a difference between left and right wheel in terms of line length. The left wheel locking up would probably be due to the steering geometry that he's mentioning, axle wrap, more weight on the driver side, and possibly unequal wear on shoes and drum. It is possible that left and right aren't adjusted perfectly symmetrical as well, although it seems like this guy is a competent mechanic so that would not be my first go to.

    Simple mechanics. The left drum locking up is not being heated by friction, because drum and shoe are fixed together. The right one dragging is generating more heat, because the shoe is scraping the inside of the drum.

    I think it still is the brakes, your left wheel locks, so there is no friction in that brake drum, because it doesn’t rotate of course. The right doesn’t lock, so there actually does is (more) friction, which is why your right wheel brakedrum is warmer... thus, your left works “harder”, because it can lock a wheel. The right side cannot, so that side isn’t as effective. You can actually check the percentage of this difference between the brakes at a garage, then you know for sure...

    It's also a shorter line from the master cylinder (under driver's left foot) to the left front wheel than to the right - it makes a difference. A common early 'rodders' retrofit was a late 50s/early 60s GMC truck master cylinder mounted to the firewall, equal length lines to the front wheels and a Saginaw steering box welded to the left frame rail.

    I agree. The left pull under braking is the fault of the poor steering geometry as you showed. Now you have a few miles on the brakes, time to do a “proper” adjustment. Large shoe to the front, L/R are mirror images. Eccentrics adjust the clearance at the wheel cylinder end of the shoes. What most people miss is the “Anchor Pin” adjustment, on the fixed bottom end of the shoes. The deal is to use a feeler gauge between the shoe and drum, top, middle, bottom of each friction surface. Modern vehicles have a free, unfixed connection at the bottom (the single star wheeled adjuster). It takes a little patience at first, but is really not that complicated. Don’t forget to have someone in the car to gently apply the brake when you hand spin the wheel, then check your adjustments before you move to the next wheel. About a 5 beer job, 2 during, 3 after😉

    A very common retrofit on modified 'flatties', as well. Saginaw steering boxes are often seen welded to frame rails of old Ford and Willys 'Jeeps' in the U.S. for good reason. Not only does it solve the axle wrap issue, but the ross boxes really weren't very good.

    Very interesting, maximum braking occurs just at the moment before they lock-up and is it at that point the car veers to the left? So, to avoid trying to fight it and potentially loosing control, cadence braking (which is what a modern ABS would be doing) would be the way to maintain a straight line under emergency braking situations. I guess with modern trickery on cars that most of us drive mean we don't use the techniques of old. Good little experiement and very good to get to know your car better! Thanks for sharing!

    The break that is hottest should be less effective to a point, it should be less likely to lock. The proportioning valve (I wonder if those Jeep’s had one!) should help that. Maybe that is why they became common. Nice video, great keep keep them running…

    For anyone that wants to learn more: All single hydraulic brake systems have equal pressure in all the lines at the wheel cylinder. They all work on a form of mechanical advantage. As long as there is no air in the system, a hydraulic line that's 6 inches Long in parallel with a hydraulic line that's 10 feet long have the same PSI at the end of the line. Back in the old days the lines used to swell, which would account for pressure differences amongst lengths. Nowadays with new brake lines not so much, especially if you have steel braided brake lines. In order for the length of line to be the main difference; hydraulic fluid would have to be compressible, this would account for the different pressure rates over length of hydraulic line. But that is a physical impossibility. Hydraulic fluid is uncompressible. This is what makes hydraulics work in the first place. This is also why hydrolocking an engine will break Pistons and Rods. Your engine is trying to compress a liquid which is impossible so something else has to give way. The old school hot rodders would equalize the lines not because of pressure differences in lengths of line, but mainly due to stretch of line material. Now I just looked at the diagram of this Jeeps breaking system and there's not that big of a difference between left and right wheel in terms of line length. The left wheel locking up would probably be due to the steering geometry that he's mentioning, axle wrap, more weight on the driver side, and possibly unequal wear on shoes and drum. It is possible that left and right aren't adjusted perfectly symmetrical as well, although it seems like this guy is a competent mechanic so that would not be my first go to.

    Nearly all vehicles pulled to one side or the other for decades (especially when you lock up a wheel) and for very simple reasons and why anti-lock breaks were developed. One side will inherently slow the wheel, if not lock it up before the other pulling the vehicle to the left or right, a big factor is the weight distribution between the wheels, wear in the brake pads, mechanical wear, differences in wheel temperature, surface conditions and etc... In northern climates, we used brake pumping to help keep the brakes from locking up on ice for years before the modern breaking tech came out helping to solve the problem, even the first anti-lock breaks would pull a little depending on surface conditions and the same factors.

    The hotter the brakes the more fading you get. That means it makes sense that the brake that doesn't lock up is hotter. It could be because it had to work harder during the first tests where the jeep veered to the left. The wheel on the outside of the curve hat to work harder because the wheel travelled a greater distance.

    You need to remember the bump steer and compression steer while it was notably on the Jeep (I have heard about it, though never driven one) was common on trucks and many cars of the time. So any of those young guys that grew up on a farm or handled trucks would have been ready for it though perhaps not as much as they got. Even 1980 solid axel chevy trucks would do this though to a lesser degree, as well as modern jeeps. All solid front axels will, as you point out one end is moving relative and one is not, steering must be done. You just counter steer, It can catch someone off guard who is not familiar, or in a war zone. Or if you have only driven modern vehicles with IFS you may be totally unfamiliar. I don’t know if it is “deadly” but defiantly could encourage you to say hi to the ditch. At least it is a left hand side arm. Other wise in your country it would tend to shove you into oncoming traffic. Not sure which is better.

They said some drivers broke their hands when they did not pay attention and the gearstick struck when the gear was not put well. This truck was so loud that you could not talk to the guy beside you. The engine was right between the two seats. And I tried to use the horn in a tunnel. The engine was so incredibly loud that you could not hear anything but engine noise and vibrations.

    I have a 1948 CJ2a Willys Jeep.....the brakes are terrible! I rebuilt them, new shoes, new brake slave cylinders, new master cylinder......they leaked soaking the new pads. Brand new, and they leaked. I looked into a disc brake conversion and found out that there is a residual check valve inside the master cylinder that is supposed to keep 8-15 pounds of pressure in the system at all times to keep the cups sealed on drum brakes.....a lot of companies are not putting that valve in anymore. Disc brakes don't need the pressure valve. Brakes and steering have always been a weak point in the old jeeps. Really, they are death traps......they are also classic cars you can take to the mountains! Love hate relationship for sure!

    Beware the 'death wobble'. It is a very real phenomenon. If (when) it occurs, let off the gas and ride it out, don't fight it hard, do not brake. Early 'Jeeps' had a truly horrible steering system. From the Ross worm gear to the spindly little connecting rods, awkward geometry and multiple ball joints, all must be in proper order as well as proper adjustment of wheel bearings to eliminate (most) wobble.
