Note to self - self, whenever someone else has driven the coach, be sure to check everything.....
With the transmission fixed (we elected to have the 3.5 chain installed as long as the trans had to come out anyway) we headed for Santa Cruz where two of our sons live. Very hot day. The coach felt very sluggish, not at all what our other coach felt like with it's 3.5 chain. As we started climbing the steep grade over the hill from San Jose to Santa Cruz the engine water temp rose alarmingly. Once we crested the brakes felt wonky like they were going away. We managed to get to one sons house stressed out about what might have gone wrong that would have the coach loose power, over heat and loose braking, and what we might have to do about it.
Anyone guess yet what this issue was?
Yup, the tow truck driver set the emergency brake, something I rarely ever do. Leaving Manny's is a downhill experience so I didn't notice that it was set. Our dash air has some electrical glitch that I will sort out today so the windows were open on this very hot day. Out on the freeway with all the traffic, noise and confusion all I felt was a sluggish coach that did not seem to have the power one would expect from the 3.5 effective gear ratio. Going up over the grade the dragging brakes heated everything to the point that the rear brakes were faded out on the downhill side so felt really strange! Once they cooled off and I released the e-brake everything returned to normal. Now all I have to worry about is whether the rear brakes are fried beyond recovery.
Once we confirm the state of the rear brakes we will make the last 500 miles of this most interesting 3500 mile journey back to Kerby, Oregon.
With the exception of the odd failure of a $.50 clip ring holding the chain gear in place on the original transmission and the improbable omission of that same clip ring on the replacement transmission, the only trauma has been the initial over heating caused by a faulty fan clutch, an electrical glitch preventing the dash air from working a few days ago after 2800 miles of blowing cold, and this failure on my part to notice the e brake being left engaged. Not bad for a 36 year old coach coming out onto the road for the first time in a long time. Before I jinx this last 500 miles with my optimism, let me add a "so far" to that last few sentences!

Jerry,
Be sure to flush the rear wheel cylinders as the unit must heated and coold
and drew in moist air.

"Parking Brake" has bit me several times. With it on, the result is a very unresponsive coach. I now check mine every time that I move it. Need to put a sounder or flasher light on the handle for an additional reminder.

I bet that has happened to a lot of US Jerry. Why not run the genset and

If your brakes got that hot you best inspect and repack your rear bearings.

Actually, the drum brakes can tolerate overheating more than the disks.
There is a greater distance from the drums and linings to the wheel
cylinders and flexible hoses on the GMC rear brakes, compared to the disk
rotor and caliper piston and flexible hoses on the front end. Can't vouch
for the wheel bearings on either end if the overheating is severe enough.
When I first got my 78 Royale, the caliper piston on the drivers side front
was welded to what was left of the brake pad..Had to air chisel them apart
before I could remove the caliper. Cooked the Rotor, Caliper, Hub,
knuckle, wheel bearings, outer cv joint and axle stub, and melted the brake
hose. Very spendy front brake job. Did both sides. Rear ebrake cables were
rusted solid from no use or maintenance. Did the rear brakes as well..

Yes, I have a complete new set of bearings, cylinders and shoes. I was thankful not to have any trouble on the return trip. I'll also be adjusting the Ebrake properly so it's obvious that it's on. I'm hoping that when properly adjusted it will hold the coach on a boat ramp.

Ha, for me it wasn't the coach parking brake.
We don't always tow. We left La Verne, CA, and we're on the 210 going West on fairly flat ground. The EBL fuel injection has a MPG reading. I glanced down a couple of times and wondered, why am I only getting 7 MPG? The third glance I hit the off ramp. Ruth ran back and sure enough the toad emergency brake was on. I went back to inspect. Luckily I had just given a tug to hitch up, but it warped the little plastic covers in the center of the rear wheel. Duh! That wasn't very smart, was it George?
BTW the E-Brake still works fine with no adjustment. Bearings and all looked great.

I've been away from the net focused on some other issues here. It's a bummer reading Jerry's account of life and it's pitfalls. Yea, as Forest Gump says "IT happens". It's what you do about it thats whats important. The tranny deal was one in a million-- truly. How can you make a backup procedure for that! All I can say is if Jerry had any other machine he would have really been screwed. As it is, isn;t it awesome the GMC community has the support group it has. That's worth having one of these machines right there! It will be interesting to see how the brakes faired through the ordeal. It all was good to go when it left here and having it all cool off and start working again is pretty exciting. The grease has to be liquified through all that but hey, it was good Valvoline synthetic so lets see. What a failure test!!!!
Jerry, you have a way of attracting excitement, just remember excitement can cause excitement! Hey but if there were nothing out of the ordinary-- I mean what would keep your heart pumping! Stuff really does happen, it's less a matter of finding fault but more of how do we get going again and it sounds like you passed that test with flying colors. That coach has proven it's a trooper and it has been waiting for you to give it your love. I appreciate your interest in the GMC, you truly are bitten! Keep going, resistence is futile...
