Hi, I recently picked up a Sears Gt16. The model number is 502.257043. I've talked to my local Sears store and searched long and hard on the internet, yet I still couldn't find a owners manual. It has a Briggs and Stratton 2 cyl. , 16hp vertical drive motor with a 4spd. gearbox with reverse. Also, it has a disc brake. If anyone has any advice, parts, or a manual; your feedback would be greatly appreciated.

-Michael

Here is a thread on rebuilding one last year. I'll see what we have in the manual section.

By any chance, does anyone know how to repair the disc brake system on this tractor. Mine is not braking yet it doesnt seem to be broken. it seems to  be a system of rods and springs. help?

Michael, KennyP is the one you need on this and he will be back on around 4AM or so. Hopefully he can help you tomorrow. Can you post a couple photos of your GT16 and the brake system?

I have searched around my usual spots and can't find a manual for this. But, I'm thinking the brakes may be very similar to the LT4000 that I have. It is a six-speed, but the brake is on the same side and may adjust like it.

This the Sears parts diagram for your tractor.

Here is the manual for the LT4000. see if it may help with the adjustment you need.

That is an older tractor than what I thought. Is the brake on the left or right?

That is different from the LT4000 for sure. I don't remember seeing one with the brake like that! I think this is from the late '70's.

Ok, I was speculating what decade it was from. Some of my friends said it was probably form the 80's. I did some digging on Sears Parts Direct and managed to find some parts diargams although, they didnt have a manual. Furthermore, I think I found out why my brakes werent working. There is a keyed shaft that the brake rotor assembly slides onto the tightens with headless bolts. The key in question is unfortuanately missing.

Looks like a mechanical disk brake that I have on an old go cart.  If it is, the first thing to do is see of the cam lever with the bolt through it is moving.  Looks like it is as there is wear on the disk, itself.  There should be a bolt with a self locking nut that runs through the center of the cam lever.  Tightening that nut, will compress the "caliper" and move the pads closer to the brake disk.  There should also be linkage that can be adjusted for the fine details.

I seemed to have fixed the brakes. There was a keyed shaft without the key. I took one off my old john deere 110 that is no longer functional. The thing that holds the rotor would just spin on the shaft as there was nothing holding it in place.
