I think I've come up with a totaly new way to hook up 911 parking brakes. It involves making up longer hybrid cables.
It's not complex, doesn't cost tons, and is about as straight forward as possible. It functions exactly as intended in the 911. Here is a teaser photo; (IMG:http://www.performanceforum.com/wesvann/914a/my-rear-brake/b-mrb1.jpg) Here is a link to my write-up on how I did it (it's a preliminary write-up). hybrid cables Wes (can somebody please find me the photo that I've seen on this site where somebody used a cable end block at the parking brake lever that had set screws) |

I think another way to say what Eric is saying is...
While you have the pins that keep the shoes attached to the backing plate, pretty much the shoes, spreader and adjuster pretty much float. If you didn't have what we are calling the "stop block" or "spacer", if you engaged the e-brake and tried to move the car, it would either rip the pins from the backing plate or break the pins as the shoes, spreader and adjuster rotated with the disk/drum and the backing plate remained stationary. You also wouldn't rotate much before your cable broke or yanked the spreader out from between the two shoes. So while the spreader moves them apart, most likely one or the other shoe (depending upon which way the car wants to move) is in contact with the stop block. This is why in my opinion you should not weld the stop block to the thin walled 911 backing plate. And as you mention Clay the 944 backing plate it a heavier cast part and not a thin stamped part because it includes the stop block and can take the load. The load at rest on the level is probably pretty small/next to nothing. But I think that the load is much higher if you tried to engage the e-brake while moving or if you are parked on a hill. |
