135 brake rod and handbrake rod set up

hatchy · Sep 10, 2018

As title really. Followed a post I found online by DavidP about properly adjusting the brakes and it went well. Thought I would have a go at one of the the other 135's we have and noticed that how the brake rod and handbrake were attached to the arm at the rear were opposite to the one I had been working on. The one I set up properly had the brake rod attached at the top of the arm and the handbrake rod came down,passed through the end of the brake rod and attached to the bottom of the arm. This would seem to be the 'correct' way given the way the brake rod is built at that end to enable the handbrake rod to pass down through it. The other and the one down at our other dairy are attached brake rod bottom and handbrake rod top and obviously it doesn't pass through the brake rod. On the these two,the handbrake rods are sloppy as hell as they are taking a shorter route to the arm. I had a look about online for videos and pictures but that throws up both scenarios too. Is there an absolute 'correct' way?

Hi, first of all, are your 135s UK or US
made? To the best of my knowledge 100
series handbraked tractors were not widely
available in the US with the preference
being for the pedal ratchet and pawl.
European and UK tractors had the HB as an
option originally. For these tractors the
'right' way is to have the HB rod passing
through the pedal rod and attached in the
lower hole of the brake drop-arm. If fitted
the other way the HB rods are likely to be
excessively long and of little use. Semi-
industrial tractors had a slightly
different system with the HB rods running
horizontally rearwards.

Thanks for reply, it was your post I found online from way back in 2007 that I was following. I'd already pretty much made up my mind that the two 135's with the handbrake rod not going through the brake rod to reach the bottom hole are incorrect. Spent an hour this evening on the one that's here freeing up the clevis pins on the arms and then tomorrow evening I'll set them the right way and then adjust the brakes/pedals. Whoever did it must have known something wasn't right as they had to bend the brake rod arms a bit so they didn't foul the foot rest bracket at the back.

This video shows the incorrect way then. As you can see he has had to bend the brake rod to clear the foot rest bracket because it is in the incorrect (bottom) hole on the back arm.

That didn't work then.

If you type in MF 135 brakes in google there is a 34 second video of a bloke showing how the shoes are opened up by the cam when you press the pedal.
