Do new brakes rods really stretch??

whirnot said:
Of course they stretch, just not much. My guess is you compensate for the stretch by tightening the adjuster 1/16 of a turn per lifetime.........

Are you turning the brake adjuster or the brake rod clevis?

No problem turning the brake adjuster 1/16 of a turn.

If you took a kinked rod, straightened it in a large vice, Also straightened the forged eye, then trued it with a BFH you could lengthen the rod. I have seen a few junk yard rods that look amazingly good after the rework.

I would think this scenario would be most likely to result in the snapped-off end pictured on Vince's site. I for one would be a-scared to use such a rod.

Years ago I bought '29 Roadster that somebody else had worked on, and had added hydraulic brakes. The 'rod' between the pedal and the MC actuating bellcrank was a bent, kinked, corroded, rusted, and SOLDERED piece of steel cable. After replacing it with a piece of actual Model A brake rod I now have good brakes on the car, which I've taken to calling the 'Sow's Ear.' [So I don't have a silk purse, but a clean, shiny sow's ear.]
 
Tom Foster: Different part. the offshore actuater from the pedal to the cross shaft is junk! As vince showed(ford garage).
The OEM brake rods from the drums to the cross shaft are the subject of this thread.
They appear to be forged at the eye end and are mallable. A cautious person would only trust what he believes is safe. Have at it. Bob
 
Unlikely any human could generation that much force on the rods via the break pedal. I would think other components that are adjustable might become loose after the rods and other other new parts were replaced in some cases.

How many detents does those brake adjusters have machined into it? :confused: Still kinda difficult to adjust it correctly turning it 1/16th of a turn.

My brother dropped his screw for his eyeglasses into a shag carpet. I told him to put a nylon stocking over the end of the vacuum cleaner hose and go over the area. He found it in a couple seconds.:)

It's mind boggling to think of the things we learn here! BUT, once we've learned EVERYTHING, we DIE!:eek:
I almost "died" today, I BROKE my FAVORITE coffee mug, life will never be the same again:mad:! My coffee even tasted "different" in that funny shaped GREEN mug.

Seriously though, Like Steve said in post #19 the rod from the pedal to the cross shaft sees 4 times as much pressure than an individual rod. Wouldn't it have to stretch 4 times as much first??
 
I have trouble believing brake rods stretch. If they did I believe DOT( Dept. of Transportation would be all over the manufacturer. I have supplied some classic cars with stainless brake cables. The cables are wound with an interior right hand wrap and the outside strands with a left hand wrap to prevent stretch or unwrapping. A friend of mine who used to handle DOT 5 brake fluid bought in 55 gallon drums repackaged it into quart containers. He had to have special DOT permission and inspection of his repackaging. IF brake rods stretch I should think that the liability put on the manufacture and selling of this type of item would not make it worth making and selling. Even wheel cylinders,brake drums, linings and other brake items are carefully scrutinized by DOT.

Just curious, are you suggesting that DOT is scrutinizing the Chinese-manufactured brake drums being imported for Model-As?

Vince,
Always enjoy your repro hall of shame......
Probably an old Rick's piece of junk.. or some other inferior part. I'll be the original rods wouldn't have done that! Thanks for sharing... it goes to show that stuff does happen. My take is that overall I really don't think the rods stretch to any degree.. but certainly in the repro world of metallurgy I agree that failures can occur. It wasn't too long back that the adjustable eyes were cast iron.

Thanks for sharing Vince..
Larry

Even at my age, I look for older folks to ask questions of. If you look in some old 'mechanics' books from the teens and twenties like the 'Dykes' manuals, you will see all forms of 4-wheel brakes, 4-wheel steering, etc., etc. All we are doing now a days is 'polishing' what those old guys have already figured out.

Besides, comedian Richard Prior used to say that the reason you don't see many old fools, is that you don't get old being a fool!

Lets add electric cars, hybrids, one coil for each plug, and list will continue on. That is why i get a kick when people say, "if that was was so good why did they change it?". I wish I could send them a dykes manual.
