Good morning all, Does anyone have a fix for a loose rear brake pedal pivot pin? Any ideas would be greatly appreciated.

What is making it loose? Is the pin itself loose on the frame? Is the pedal worn so that its hole is oblong?

The pin itself is loose in the frame.

There isn't much to move there:



The splined area is where the brake pedal clamps in place, and the divot in between them is where the pinch bolt goes, to prevent the pedal from falling off even if the pinch bolt loosens off.

The pivot itself just pushes through from the back side - the two springs (return spring, brake switch spring) and the clevis connecting it to the master cylinder keep it more or less in place, and the brake pedal clamped in place keeps it from backing out and falling out.

There are only a few things that can cause it to come loose:

- Pedal not pushed on all the way, allowing pivot to push through partially into frame
- Insufficient lubrication causing wear on the pivot, allowing it to move around inside the frame
- Insufficient lubrication causing wear on the frame, allowing the pivot to move around inside the frame

The first one is easy to check, the pedal is either all the way on (outside end of the pivot level with the brake pedal), or it's not.

The other two you're going to have to remove the pivot to check its condition, and the condition of the frame opening.

Thanks for all the info. I think the next step is to remove the pivot pin and check to see which part is worn. If it's the pin. try and locate one that is in good shape. If it's the tube on the frame, hone it out and have a brass bushing made to insert into the tube. I may have to turn down the pin on a lathe a little. I'm thinking some shim stock may rectify the issue, but first tear it apart and see what is worn. And finally in stall a grease fitting on the tube. Does this sound like it may correct this issue? PS. The pivot pin is no longer available from Honda. Again, thanks for all the info.
