I'm trying to resolve the issue with my parking brake locking up on the back of my 2 speed automatic. Part of it is a leaking transmission seal, which I'm fixing with a new seal and sleeve. I decided to replace the parking brake cable and fix the loose backing plate while I'm in there. Question 1: On the backing plate, there is a cable clamp (pictured below). This clamps over a threaded piece of the parking brake cable (second image below --There is a nut on the parking brake cable which I have already removed). Even though the clamp is tight, I was able to easily pull the old cable out without loosening the bolt. Is this loose because of 60 years of wear and tear, or is there a part missing that got lost along the way? Question 2: There is a neoprene seal on the backing plate (third image down.) When the parking brake is applied, the pressure is put on this seal. Over the years, this has damaged the seal. Seems like a strange way to design things to me. Anyway, this allows the backing plate to move a little - like it is loose. I doubt I can find a replacement. (at least my main parts supplier had no idea) Does it matter if the backing plate is loose? The backing plate is where the parking brake cable is anchored. If the backing plate is moving, it seems like it would be moving the brake shoes a little, though probably not enough to matter. |
