Today is brake/clutch day!

[Bange]

As the pedal is unique, the logic is that at the beginning of the pedal stroke, the clutch is activated/disabled and then the brake.
Separately everything works, but there is a jump when leaving and a certain delay in starting the brake, seeming that the functions are overlapping.
When disassembling, I could see several worn components that I believe are causing the inconvenience.

Parece que esta peça já foi virada um dia...




Some components are not part of the diagram but perform the same function.

The sum of these gaps and others that are difficult to photograph must be the cause.
Am I right in my reasoning or is there something else?

There should be an adjustment on the rod that activates the brake which usually also has an over run spring
You back it off so that the drive cutch just starts to slip before the brake engages or dissengages .
The brake is either on or off there is no slip because it works by locking the diff so the wheels turn in opposite directions which is why it is so abruptIT is exactly the same as the P position on an automatic transmission

I only identify an adjustment in the approximation of the pads to the disc.
And it makes sense to start the brake only after disconnecting the transmission (by belt) from the gearbox.
On the pedal shaft, there is an ear with an oblong hole, which allows the brake to be activated some time (angle) after disengaging (or together?) the clutch.

Not a set of linkages I am familiar with
On all I have worked on the rod # 29 would pass strait through the brake lever a long way
Then there is a compression spring and a nut passes that so you can adjust when the rod pulls the brake lever on .
If the brake rod pushes the lever to activate the brake then the spring & adjuster nut is forward of the brake lever .
In the middle of the brake lever is a stud & nut
That moves the lever closer or further away from the pins that push on the brake pads so there is an adjustment there as well .

Rod #29...#26 is a spring...
But I believe that in fact there is something different that is not showing up in the diagram... I'll clear that doubt tomorrow.

The image of the brake rod is wrong for the style transaxle brake lever shown. The spring you are noting is on the brake caliper and is to pull it off. Also is #161 spring present and correctly connected.

Why are you not posting the equipment model number?

I am getting so frustrating with posters asking for help but refusing to provide the info we need to even look up the equipment. Come on folks not every mower is the same setup by a long shot. Just because it is a Murray doesn't mean a lot as they were built by Murray Ohio, Husqvarna , and MTD. Some things I can gradually work it out but it takes time and some days I am too busy to done it as I got own shop problems to research...

I am to a point of just stop trying.....

Yes Sr. ...


Motor
Model - 31P777
Type - 0602 B1
Code - 100209ZD

Did I forget something?

PS.: I just remember that my mower is frankenstein's cousin.

Your mower was built by Husqvarna but I not able find 960420056-03 maintenance level (-03). All I am finding is maintenance level -04. So I don't know what the changes that were made between level 03 and level 04. And Husqvarna site don't find either version. Damn I hate OEMs that hides things.

The rod should one with a thread end, spring, washer, and nylon lock nut and not what is being shown in the image of the brake/clutch system.

Sorry can't be of further help but yes the info in your post was very helpful in looking the mower and is much appreciated.

My system is...

No threaded rod, bushing...
I think it was made during the period when employees didn't know who was going to be the boss...kkk...
The adjustment can only be made by the central screw of the brake assembly.

And don't worry... as I said before, any opinion is welcome.

Your comment about the various owners of Murray is interesting... it seems that Murray is an unwanted child, an ugly duckling that nobody wants...

So it could be that my deck (Husqvarna) originally came with the machine... and I'm blaming the previous owners.

Well, my assessment of my system can be seen in the following scheme:

As soon as I finish resolving the gaps I will confirm... or not...
