- Hi, I'm Bob Shrupp, physical therapist
- Brad Heineck physical therapist
And together we are the most famous
physical therapist on the internet
- In our opinion, of course
- And I also do some dentistry on the side.
- Ahh
- All right, Brad, today, we're gonna talk about how
to fix the brakes on a four wheel Walker.
These walkers have become very, very popular
for the elderly, which brings us to our first point
by the way, if you are 40, 50 and over,
and you're don't wanna subscribe to us
because we can provide you videos on how to stay healthy
and fit and pain free well into the elder years.
- Right? And both Bob and I are
that 50 age are both of our parents use four wheel walkers.
- Yeah. My mom uses the four wheel walker
- And they're a wonderful thing on the.
What's good about these Bob?
- Well we're gonna talk about that in another video Brad.
- Oh, that's right.
- We're gonna talk about how to fix the brakes now.
- Oh, that's right. You're thinking Bob.
- So watch our next video.
We're gonna talk about the pros
and cons of this one, but right now we're gonna show
- As far as safety, the hand breaks are critical
and these breaks work well if they're
adjusted properly.
However, they can get unadjusted and they can loosen up.
So that watch this break.
If you push down this back wheel right now is locked.
I can't move the Walker forward or backwards.
Now this one should have the same response and it's
clearly out of adjustment.
It's down it's not locked.
And the goal for this is you lock both of them so
that you can sit down in the stationary versus sitting down
and having it go away on you and have one of those falls
which you really don't want to have mom or dad experience.
So you gonna say, don't worry, mom
I can fix this cuz your parents always.
- Because your handy. You may not be handsome.
- Yeah. It may not be handsome, but find yourself.
That's a red, green thing.
You don't want to take kids in for material.
But if you go right here where the cable goes into
- Focus on that
- You down here?
Okay. Now this is the same as on a bicycle actually.
So they're gonna find kind of a neural
nut right here.
And then there's gonna be a lock nut right there.
And if it's loose already, watch what happens.
Right now it's not working.
It's a little bit.
If I move this and if you look close
you can see the distance from this finger nut up
to here is increasing.
As I go that way, you probably won't be able to see this.
But if you're here in real life, you'll be able to see it
and see the distance between the, the lockdown is changing.
You can see more threads now, before there was very
few threads and then now the lockdown.
That's why I have a needle nose.
If you're a real mechanic,
you won't use a needle nose.
Those, you get a nice pair, a nice box in
but most people don't have that laying around their house.
Okay.
- [Bob] So which way is tightening in Brad?
And which way is loosening it?
- [Brad] Well, you go this way so that you see more thread.
- [Bob] You see more threads here. Okay.
- [Brad] Depends way you're looking at it
- [Bob] So there's two components here.
There's little what do you call that?
- [Brad] It's a neural nut.
I'm gonna call it a neural nut.
- [Bob] That's the first thing you run
into. And then the next one is just a regular nut.
- [Brad] Then that's the lock nut.
Once you get it adjusted not a lot.
- [Bob] So you move the,
you move this one first to where it's adjusted.
- [Brad] Right? So then when you push down, see how
much it clicks now.
- [Bob] Okay.
- [Brad] Then look at that.
That is locked tight.
- [Bob] All right.
So once you got that one in place
then you gotta put the lock nut in place.
So it doesn't move.
- [Brad] Yep. And I'm gonna take this needle nose again.
An open-end wrench would really be nice
or a small crescent wrench, but you can get away
with this it'll work.
And yeah. And there we go it's tight.
And I can actually.
- [Bob] So now I can see a lot of, again, Nancy, I don't
know if you're catching this.
You can see a lot of threads right there where
before they were actually, the two were together.
- [Brad] Right.
It was all moved in.
- [Bob] So the more that you move this nut,
that way, the more it tightens it.
The more it went this way is the more it loosened it.
- [Brad] So now the other thing is
if you got this all the way out and it's still
not locking tight, tadah.
They've got another one down here you can do
the same thing with exactly the same setup.
- [Bob] Oh yeah.
- [Brad] And if you move both
of those all the way out and it's still not tight enough
then you gotta come down here and you gotta
loosen this up and pull the cable through.
And that's a whole other story.
- Usually, I've never had to do that.
I've always been get up with just this one
and I've never had to go to the second one actually yet so.
- [Bob] Okay.
That's helpful , because like I said, Brad
this actually becomes a device of worry.
If the brakes aren't locked.
- [Brad] Right, yeah. You think you're gonna be safe
with your four wheel locker and the brakes don't work well
it's actually puts you more danger so.
There you go.
Any more questions on a four wheel Walker,
just write in our comment section and I'll be happy
to, Bob and I'll be happy to answer you.
Sounds good. Thanks.
