@cuinrearview this why you need to have a pocket full of individually wrapped singles when you head over here...

How so Timofee? All i can think of is a heavier load on the trailer has more kinetic energy when pushed against the stopping tow wagon, thereby squeezing the master cylinder with more force and subsequently delivering higher hydraulic pressure to the brake pads?

Mr, Dream answered on the parking brake lever deal on the rear.
And I believe the adjuster on the bottom with the jam nut affects stroke of the master cylinder depending on how hard a push the load on the trailer generates.

Cheeky...
The parking brake, or more correctly the sabre toothed lock, is the source of a bit of trouble on them. Rental trailers locally its normally removed. Who would be stupid enough to tow it with the park brake on? i thought once....well remember when Lloyd borrowed my axle stands last week? Was because he'd cooked the pads and grease....

Pun intended, Can't Fix Stupid LOL! Nuffins derogatory against Lloyd of course!

It's a dude that owns it.
He washes cars here.

Made me think Timofee, which i like. The jamb nut doesn't affect the fulcrum length, just the clearance between the pushrod and spring cylinder. Once the reaction cylinder travels enough to move the rocker, its the same amount of force applied to the master cylinder regardless of that jam nuts setting no? We aren't changing the mechanical advantage via the rocker length on either side of its fulcrum point?

We park between the lines as a rule, but our toilet water spins out the other way to yours too so what do i know...

Yes sir I understand you are not changing the fulcrum point at all. And I may not have my head totally wrapped around this yet, But,
By changing the lower spring screw setting either by length or shortness, aren't you essentially affecting the spring push affect hence the master cylinder piston movement. I'll look at it later on the way home my man.

Adam, Let's rethink this a minute if this is the trailer you and Lloyd are having brake issues with.
Applied brake pressure is unknown right. Put an inverted double flare brass tee with a gauge port in the master cyl. delivery line to trailer. Just in case you are fighting with a broken spring right.
Then back the trailer gently into a firm object-stump, loading dock, Dodge-whatever. And see how spring travel and bottom screw adjustments affect applied brake pressure when backing the tow vehicle rearwards. If very little travel heightens pressure then I would say maybe a broken spring.
As a note of interest your gauge should be in the 3-4k range and put them New Zealand goggles on sir. I don't want to hear of any bodily damages. OK
BTW, Just how large and heavy is this trailer empty??

400.00 or so later......the lift cylinders on the 2640 are rebuilt. Now to get them back on the tractor.

I was thinking the same, less bump and more gradual braking. Or grab of brakes and snatch…. A rubber band effect.

with more or less weight the effects would be amplified.. as with nose weight of the trailer, a later braking trailer could make it uncomfortable for the driver…but I know driver driving styles differ so the the trailer braking characteristics would differ to the drivers..

l'm just saying this from driving with a 1.2t unbraked trailer with a lot of slop in the not working braking system … with a car that shouldn’t be pulling more than 1t, the car only weighs 700 or 800 kg
It was ok most of the time but other times, I didn’t know what was going to happen..

But We know it’s needs to behave while being towed

Like the porters say Sean. It's all in the squish LOL.

Threw the sons welder on my old junk hauling trailer. Screwed his storage box to the front. Gonna make some hangers for the leads, and that thing can go to his house.
Got tired of it sitting in my building.
Got the tarp over it to keep some of the rain out, if we ever get any more rain...

Did I mention its hotter than two rats humping in a wool sock?

Gonna try to do some blackenned Mahi Mahi for dinner.
Skillet is getting better.
This apparently did duty as a cornbread skillet, and they cut it in the pan.
I can see the knife marks in the cast iron.

 

[birdmeter]

cast iron good.

Works perfectly Timofee. As long as the tow wagon can stop, the trailer will apply it's brakes very soon after in perfect proportion to the weight. It's a simple, reliable system.

As long as you don't leave the handbrake locked on...

TGIF, the day is in the books and the weekend has begun. Pizza and first beverage are down, starting to feel human again.

Was chatting with the retired boss today, he had just got back from spending a couple days on the farm with his nephew. They had 54 calves born on Wednesday, 17 required pulling. Can you even imagine? I sure can’t.

Took off my saw porter's hat.....donned my farmer's hat. Off to spray more pasture
