The handbrake on my '71 (folding lever) has never locked in place (i.e., the ratchet doesn't work). Today, I took it apart to fix this, and I can't figure out what's broken or missing.
Looking at PET, I see part 901.424.508.00 (ratchet, though I'd call that a pawl), and 914.424.541.00 (locking segment, which it'd call the ratchet). Both are present and the teeth are in good shape. What I don't see is a spring either in my handbrake or in the PET diagrams that keeps the pawl against the ratchet. There's a spring that holds the button you use to unlock the ratchet, but no spring to lock the pawl against the ratchet. Thus, no clicks as you pull up, and it doesn't hold. How is this supposed to work? I note there is a return spring (914.424.545.00), but I can't figure out where it's supposed to fit from the PET diagram. I seem to be missing something (mentally). |

There is no spring. I used to be able to do it, but others could not. Left my car off one time for service and came back with both rear brakes disconnected. The trick is to rock the floppy part of the handle back against the stop,and press the button. Then it would go down, holding it against the latching part. Make sense?? Jeff |
