fish eye clevis lengths

[mcoomey]

As part of my rear brake servicing I decided to clean up and paint the brake rods, levers, and clevis pins on the service and emergency brakes. Before disassembling them I failed to notice that there are different sizes -- 2 inch and 2½ inch. My question is which size goes to which brake system?

If you look carefully at the holes in the clevises, you will see 2 have larger diameter holes. Those are for the e-brakes. The other 2 have standard service brake size holes.

Another way to tell is to dry fit the ends to their respective cross shafts. They will only go on one way - as Jim states, the larger holes go on the E-brake cross shaft, and the smaller ones go on the service brake cross shaft.

BTW, it's not uncommon for the service brake ends to get elongated from wear. This will result in some slop in the brake action. Replacements are available from all the usual vendors.

Great! Thanks to both of you for the info. I'll try to pay closer attention during the disassembly stage next time!

As are oversize pins.

Master - with oversize pins you need to drill through both the brake rod end and the arm on the cross shaft to open them up. That's kinda irreversible, so I generally don't recommend that. But if your cross shaft ends are also wallered, you don't have an alternative (short of welding them shut and starting over, see "restoration") and yes, the oversize pins are a good alternative at that point.
