Disc Brake

Peerless 800 series transmission. Where do you put the brake rotor. There isn't enough room on the axle between the tire rim and the transmission case.
Thank You

You need a brake hat to offset the rotor over axle housing. 

You may have to have one custom made.   I?m not sure if anyone is producing them anymore.

Skip, 

   Can you send a picture of the back side of the hubs/rims you're using on your 800 transaxle, as well as a picture of the rotor hubs?  You may not need the hats.

Not able to send pic at this time and may be approaching this project with the wrong equipment. The transaxle I have isn't the one that came with the mower, but the bolt pattern is the same. Murry chasis . As I mentioned it is a peerless 800 series and I have locked the axles.
The  intent is a drag mower. Rims are 7" tall by 6" regular mower rims. There is only 1/2 inch of axle exposed between inner hub and transaxle housing. The original rotor is only 3" tall with a splined shaft. My other two mowers are built to A/P specs, so I don,t have any transaxle experience. I am not familiar with what "hood" means.
I really appreciate your trying to help.

Check this out.   This is what is called a “hat”. 

Unfortunately you need to move things around to get more than a 1/2” of clearance.  You need sone sort of hub to fit between the axle housing and the wheel hub.

Skip, 

   If you want to have a successful drag mower, your 800 transaxle would be considered "the wrong equipment."  You need an 820 transaxle -- all heat-treated cut steel gears; all needle and ball bearings on the internal shafts (no bushings); 1"-diameter axles; high-speed final-drive gearsets available so you don't have to over-rev your input shaft; and the 820 has the same mounting as the original transaxle in your Murray and your current 800, for a "bolt-in" installation. 

   Is your shifter between your legs or on the right fender?
