BX-24 brake adjustment

[ayelvington]

If you've left the parking brake on and now you're thinking you need new brakes, READ ON!

Yup, you just ate a lot (but not all) of your brakes. If the pedal goes to the floor, this procedure will let you put off spending big bucks for quite a while.

1. Remove the right rear tire.

2. Locate the brake pedal return spring to the rear of the chassis.

3. Release the return spring from the rear of the chassis and set it aside.

4. Locate the arm that engages the brake cam. The front of the spring was attached to it. (It barely rises above the tractor frame...)

5. Remove the cotter pin from the arm so that the rear brake turnbuckle assembly is free to rotate.

6. Shorten the turnbuckle by rotating the rear portion of the turnbuckle assembly until the threads just bottom out.

7. Reinstall the turnbuckle pin into the brake cam lever.

8. Reinstall the pin securing the turnbuckle pin to the brake cam lever.

9. Reinstall the brake return spring.

10. Reinstall the right rear tire.

You now have brakes again!

If you're wondering where the brakes went, they are now in your hydraulic fluid, so it might be a good time to change the fluid and filters....


There is SOOOOOO much missing from the Kubota WSM it's not funny...

Great post I will print this out and place it in my WSM for future reference.

There certainly is...plus what's lost in translation.

BX brake is essentially a clutch pack...much like that of motorcycle or auto trans. My only concern w/adjustment is possibility of exceeding wear surface on brake discs, causing metal to metal contact w/friction discs...alas, if only WSM had adjustment info so we wouldn't adjust "too far"...

As for funny...some translated text does make me smile...

good post, might explain why some are finding metal pieces in strainer.
Your shortcut is only giving you a further use of brake lining to point of no return.
Ever wonder why the brake pads on cars has squealers? some bend those tabs back to point and drive to point of no return....... I am just saying.....

The internal parts are cheap, but the remove and replace charges are not. You might as well get your money's worth if they're going to have to crack the case and go in. Replacement pads are like $60...

Until you find that too much metal has entered the system from adjusting the brakes too far............and has in turn taken out several bearings in the process, or maybe even entered the hydraulic pump.

exactly don... it appears al had his bx in shorter period of time then I do , but already wearing out the brakes. It might work for him for now till he got the time hopefully before snow falls to fix it for good.

I just hope that Al sees the posts and takes corrective action before serious damage results.
And I further hope that others that have printed the post, take heed to what was said. Big difference in repair costs on 'dry brakes with rotors on drums', and 'wet brakes' that involve Hydrostatic transaxles.

Can't be too careful when dealing with metal and hydraulics.

Kubota's engineers would need a swift kick if they let me adjust the brakes down to metal, or fed the pump from somewhere other than directly from the filter.

I regret that I can't afford to take it in to the shop for piece of mind, so I'm depending on Kubota to do their product design right.

...hopefully not same engineers who came up w/original HST cooling fan, or subsequent "fix"...

Seriously, I would be more comfortable if there were a spec in WSM...that would at least tell me they were thinking about it...

I'm with you 100% on the need for a specification for ANY adjustment. I wrote technical / service manuals for 7 years, and all adjustments required tolerances be provided. Hewlett-Packard and others were our competition, so we provided the best documentation possible.

I'll be doing a hydraulic fluid change this week, so I'll let you know what I find (if anything).

 

[ayelvington]

Did fluid change today since it rained. SUDT came out crystal clear making me wonder why I was changing it. (Oh yeah, Kubota likes the $) Pump strainer was spotless too. As far as I can tell, what wore off of the brakes was probably in the filter where it belonged.

Changed the engine oil too. I chuckled at the 100-hour recommended interval since I'd be changing oil three times a year. I'm using synthetic and just doing it annually. I know, I'm a sinner...

tractor was pretty idle while I was on active duty, but now running about 250 hours a year.

Al ,

The transmission filter is about 35 micron ( for high flow rate ) and
I don't honestly think it holds small particles . Below is my old
oil ( yuck ! ) and that was being pumped around and through
the filter . Engine oil filters are are about 8 micron ( low flow
rate ) and do have a benefit . Do bear in mind that trans oil
is also a moisture absorber too , and a couple of years is
enough IMO .......

PS Watched your Youtubes ; lovely land you have.
We get fungal root rot over here , which is very quick
to kill ( a day or so ) . Pull it up and burn it.

 

[ayelvington]

@OrangeRidge: Is the photo UDT or engine oil? I'd be terrified if that came out of my transmission!

Thanks for watching the videos and your experience with fungal rot. I suspect you're right since we have poor drainage. I'll be prepping a new area for planting that will have mounded topsoil to provide some drainage for the tree roots.

There's a promise of rain over the next 24 hours, but it looks like it's all passing south of us for now

 

[OrangeRidge]

http://www.tractorbynet.com/forums/...80869-problem-international-dry-shipping.html Now at 70 hours and the
transmission oil is clear and fine :thumbsup: , but others who
buy imported-dry trans should take heed . It wasn't as bad as it looked ,
but I wouldn't want to pump at 1850psi with that in contact with
a high speed piston

Thanks to all of you for the good information. I would like to expand upon this topic. My BX22 has a very hard brake pedal but does not hold at all. The pedal needs a lot of pressure to get to the point that the brake lock will engauge, but it almost seems that the linkage isn't actually appling pressure to the disks. Any advice?

It's possible your brakes are worn to the metal-on-metal stage, therefore not much stopping power. How many hours/how long have you owned it?

I just pulled out a BX24 Owner's Manual.
Brake adjustment is listed as an item on the 100 hour service schedule. Page 77 decribes the procedure. Apparently, if the pedal free travel cannot be adjusted to spec, you should contact your dealer.

Additional note: Limoguy's BX22 has a completely different braking system than does Al's BX24. The BX22/3 have 2 brake packs. Some have been known to be weak. The BX24/5 have a single brake pack which seems to be somewhat stronger. Mixing comments on these totally different systems might really cause confusion. Might be reason for a seperate thread.

 

[timswi]

MY BX parking brake has been useless since day one..Even with adjustments...I just put whatever implement down and forget about it.

 

[Limoguy1510]

Again, thanks to all fro the feedback. The tractor is new to me. I have owned it for 4 months. I did read up on the brake adjustment procedure, but it seems unlikely to me that this will give me the stopping power that I am expecting. I have been using the front and rear implements to hold the machine, and suspect that I will need to continue this. On a different note, Is it common to hear a bit of noise from the gear box/pump? Nothing loud, but I do hear it when I create a load of any kind. I don't think it's excessive would feel better knowing that for sure. The Hydro fluid is full and clean. had it's 100 mile service at 775 hrs and it has just over 800 now.
