It still don't brake, doesn't even hold on a hill when I take it down a hill untill it stops it's self.
So that is my problem.
After I turned the mower on its head to drain the oil (as I indicated above), I think I worked how the brakes work on these...well how it appears to me that they should work anyway....
Whilst the mower is in gear, be it forward or reverse, there should be tension on the drive belt. With your foot off the throttle lever, there should be tension on the v-belt and the brake pad should be hard against the final drive v-pulley stopping the mower from moving. If the mower is in neutral, and there is no tension on the v-belt, the brake is basically not in effect. It seems to be the gearbox that stopped the mower from moving. If the engine is stopped, and left in gear, you should not be to push it.
As for anyone else who is looking or having issues, I've uploaded photos of the underside of my machine in this post, but note that the drive pulley assembly on the engine has been incorrectly mounted to the motor upside down and, after I accidentally ran into the back of my car due to speed on take-off in the wrong gear, it will definately be reversed to slow the bugger down. The small v-pulley should be at the top (near the motor) for the drive system and the larger v-pulley should be on the bottom for the cutter deck, which means the cutter plate and blades will spin faster, and the size of the v-pulley should also assit in stopping the cutter belt from falling off the assembly. :-)
Hope some of these photos help.
