Today was the first time I ever attempted any drum brake maintenance DIY (on any vehicle) . I made some mistakes, now what do I need to fix them.
I ended up with two extra parts. http://www.zerkelhome.com/drum-extra.JPG
I was smart enough to take a picture before I began. http://www.zerkelhome.com/drum-before.JPG
And after is here: http://www.zerkelhome.com/drum-after.JPG
Looking closely at the after picture and Using the diagram on page 5-4 of X-7725 I believe I am missing item 10 (pivot) and also item 13 (override spring).
This is the passenger side rearmost wheel.
I was working outside and was interrupted by a popup thunderstorm, then it was getting dark, and I got in a hurry. I put the drum back on for now, but realize there are issues. I will look for the missing pivot part tomorrow in the daylight. If I do not find it; first question is this a commonly available part, or something specific to the GMC motorhome brakes?
Next question; The way it is, is it safe to drive it about 8 miles to the shop that I have trusted in the past to inspect/maintain the rear brakes on this coach? FWIW, I still absolutely trust that local shop, but just wanted to try this on my own.
My motivation for diving in was; the last time I tried to bleed the brakes (which I have done successfully several times in the past), I broke a bleeder valve on this wheel cylinder. I was replacing this wheel cylinder due to that. I did get the new wheel cylinder in, but as you can see from the photos, I have issues.
I am not sure how to proceed.
