| I got to enjoy about 4 hours on the D14 today using a single cut harrow with 8 22" disk. I mashed the right brake and it went way down and now doesn't apply. What do I need to do to repair it? I assume it's the eccentric that moves the shoes. |

| You can't do anything to the brakes on a D14 until the final drive is removed. With the final drive removed you can see the problem. Ecentric is bound or maybe springs broke. |

Did the rod break or become unhooked? ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| The linkage rod looks fine. Once the pedal went down, it will return with the spring. It doesn't have the resistance like it's working the shoes. |

You can try to lengthen the brake rod. These machines are 50+/- years old and worn out brake linings are not uncommon. Brake setup is very similar to what you would see on automobile drum brakes (except the shoes go over the drum). You have to pull the finals to service the brakes. New friction material for the shoes and brake drums are available from your AGCO dealer ------------- What this country needs is more unemployed politicians-and lawyers. Currently have: 1 D14 and a D15S2. With new owners: 2Bs,9CAs,1WD,2 D12s,5D14s,3D15S2s, 2D17SIVs,D17D,1D19D;1 Unstyled WC |

I would guess the shoes are toast on that side, same thing happened to our D-14. New linings are pretty cheap from AGCO, just have to rivet them on. ------------- 30+ A-Cs ranging from a 1928 20-35, to a 1984 8070FWA, Gleaner R52 |

| The drums on the neighbors D14 had a pretty big ridge so we had them turned down. Plenty of meat left in drum but even after installing new linings on the shoes I had to lengthen the brake rods quite a bit. Its a show tractor now but for a working tractor might would want to get new drums if yours are wore much. |

| I had her torn down Summer before last, changed the transmission, replaced the seals in the differential, and cleaned up the brake shoes. They seemed to have plenty of pad then and I'm sure hasn't had enough use to be worn out. The right brake went all at once. The fluid started leaking onto it again and I was mashing it pretty hard. It feels like something broke or came loose. |

Here is a pic if you need it from the manual. |

| Since the pedal is moving the actuating lever, but the shoes aren't applying; would you say the actuating lever is not moving the actuating cam? |

| Lever or cam could be worn and they may have slipped over one another. Possibly support plate bolts are loose and things are moving around. |

| Sounds about right. Now lie to me and tell me there's a way to fix it without pulling the axle off. lol |

There is a way to fix the brakes without pulling the final drive off....lol..."magic". Results may vary...lol Its not to bad of a job on the D14. I used the WD45 with a boom pole to do the neighbors...at the time I didn't have a cherry picker. |

| Kaleb is really good with my New Holland's front end loader. He helped me when we tore it down before. Any idea why the seal would start back leaking after more than a year? |

| I did the neighbors in march so far so good. Maybe a bur or debri cut it or maybe axle is worn some where seal rides. Is it leaking bad? Is the transmission over-full? |

| Didn't see anything when I was in there before. I haven't checked the fluid level in the transmission. I notice the oil on the hitch before I started plowing and the brake didn't grab well from the start. The last time I ran it was to take it to a local show last Fall and the brakes were fine then. |

| I'm guessing you broke the drum in two. I know this is an old post I broke the drum on my 14 plowing snow but when I got it tore apart to fix it I noticed the moon shape key under the drum needed to be replaced. I have not been able to find this key anywhere wondering if anyone had any ideas. |

| If thekeyway is a half moon style keyway you should be able to get one at a hardware store or from fastenall hardware people. Leon |
