1315 with no brakes

[Matthew]

Hi I bought a 1315 a few years ago and it's never had brakes. The person I bought from told me it was just an adjustment and the tranny had been rebuilt. Well at one point I tried to adjust the brakes and ended up breaking the bracket that pushes on the brake pad. When I got the new bracket I installed but still no brakes. I took everything apart to where I could see the brake rotor on the side of the tranny. I spun the rear wheels and the rotor spun as expected. I put one finger on the rotor and stopped it easily but yet the rear wheels keep spinning. Which would tell me something in the tranny is not correct.

Would anyone agree with this assessment? Any other ideas?

Thanks,
Matthew

First, welcome to OCC....

Check the email account as listed in your profile. I sent you the Owner's Manual for the 1315. Look on pages 15 & 16 for Brake Adjustment procedures.

Thank You! I can definitely try adjusting again, but wouldn't you think since the brake rotor doesn't stop the wheels that the brakes will (no matter how much I adjust) never work unless I had the tranny repaired?

Thanks for you help with this!

Sounds to me like the brake disc internal splines or the shaft splines that brake disk slides onto are stripped if it takes that small amount of pressure to hold the disk stationary. This has a peerless lawn tractor rear end in it so removal and disassembly may be required if your brake linkage and adjustment is correct. We aren't there to see this but maybe post a video or some pictures of this to make sure. It's not that bad of a job to split the trans axle once it's out to repair if this is the case. Not sure of how mechanically inclined you are however.

Don't take me to the bank on this, but....
When you are spinning the rear wheels, are you spinning both wheels in the same direction at the same time??. I am not positive but I don't think the brake disk becomes engaged without both axles turning, that is because of the differential gears. In other words if you have the back of the tractor jacked up, or even have the tranny out and you turn one axle it will spin very easily because you are not turning all the rest of the gears inside. The brake disk may spin but just bareley from drag of the grease inside. If you spin both axles the same direction, the differential will engage with the gears on the brake disk shaft.

I'm not sayin' that you don't have something broken but just suggesting for your testing procedure. Hope it'll help.

@Alvy That's about what I was thinking, something inside that tranny case is not right. I feel I'm pretty mechanically inclined, I'm a design engineer and do most work on both my vehicles.

@ironman What your saying makes sense. I did have the rear wheels jacked up and was spinning the wheels with my hand. From what I remember both wheels were spinning in the same direction but I guess I could be mistaken.

I'll go and make a video this weekend and test these suggestions then I'll post, stay tuned.

Thanks for all your guys help!

I just tried things out on a Spicer 5 speed I have laying around. I think they should be similar inside. Anyway, you don't have to turn both axles at the same time but the one you are not turning must be held in place. So if your tractor is jacked up and the wheels are on, block one, spin the other. You should see the brake disk spin and not be able to stop it with finger pressure.

The shaft that the brake disc is mounted to, is a splined shaft at the brake disk. It's also keyed inside at the gears. "IF" the internal key was broken, then the tractor would not move. If the tractor moves, then that shaft has to spin, and everything internally has to be good. The only possibility is that the splines in the brake disk are stripped, or the shaft is stripped. The disk is removable without disassembly required. Take it off. If the disk is bad, a new one is available for about $30 form CCC. If the shaft is bad, your screwed. It is NLA. Don't bother taking it out and apart, just go find another transaxle. They used them in all kinds of brands of machines, not just CCC.

It's been a week, I can't hold my breath much longer.
