Rear brake rebuild ...
Hi Guys.
I have to go to the Tüv (technical inspection) soon, and I have to do some repairs on the rear brake. Unfortunately, when the brake was dismantled, it became apparent that the last maintenance was probably 20 years ago. Actually, I only wanted to exchange the brass sleeves for the brake camshaft and emergency brake, as the shafts had a lot of play. When dismantling, however, it turned out that both shafts have probably not received any lubrication for the past 20 years! Both shafts could only be expanded with brutal violence, gas burners and a lot of oil. The guide sleeve of the emergency brake shaft was torn off on the anchor plate. And that's exactly what I have a question about. Does the emergency brake shaft have a grease fitting? Because there is none on my shaft, but none could be mounted either ... You only see a 4mm hole there. Too small to be able to press in a lubricating fitting. When I look at the replacement emergency brake shafts at Macs or other parts suppliers, they all have an internal thread on the outside. This is missing from me. There is only said hole there. No wonder it couldn't be lubricated. If the emergency brake shaft needs a grease fitting, I would at least retrofit it. Another question: The brass bushings for the shaft bearings ... Do the new brake camshafts fit there directly, or do the bushings have to be rubbed open with an awl? Greetings from Germany / Berlin Andy |

I drilled a hole in the end of the brake shaft and also a small cross hole on the sides so I could add my own geeese fitting. |
