brakes

I have a 424 international that I really like but wish it had brakes. took apart and cleaned and oiled the balls and races and it is not a quick job. within a few days the brakes will no longer work. is there a disc brake conversion made or have some of you found what I have been overlooking? thanks steve

Hi Steve, you did the correct thing but hope you didn't apply to much lube. I used to use a small amount of graphite grease on the balls and then lightly wipe the balls with a rag remove all the visible grease. Were the brake disks glazed? Shiny? Ruff them up with a wire wheel or some coarse sand paper. Also if there is an outer or inner edge on the brake disk, remove the edge as it will ride up on the brake drum and prevent the surface of the disks contacting the metal braking surface.
Also make sure the roller grooves are not worn so the rollers don't stick part way up the ramp.

Jim, thanks. I have used more oil than that and not tried graphite. are the discs available? they seem really thin. If this tractor had reliable brakes it would be the cats pj"s, so to speak. thanks steve

New brake disks are available from this site.

When the brake disks get worn you lose mechanical advantage in the linkage causing the brakes to require much more effort to work.

Replacing the brake disks may be enough to get you good brakes but often the other wear surfaces have enough material missing that just new disks doesn't really do the job. When that happens you can usually remove a little material from the mating surface of the drum to compensate for lost material. If you go that route do not throw out the old disks until you make sure that your brakes will work Okay. If you happen to remove too much from the drum you can use one old disks to gain a little more clearance.

The best advice on lubing the internal brake parts is don't do it. Anything other than a dry lubricant will collect the brake dust as the disks wear and will cause problems. I usually use a spray on graphite on the balls and ramps.

TSC, evilpay, this site right here, will have the disks.

I used copper-based anti-sieze when I did the brakes on my SM, a yearly chore when raking hay with it. The graphite-based stuff gummed up when it got hot.
