Nice to see more western dates!
Western? About 60% of the county is West of the most western venue listed.Quote:

Its listed as tentative until the owners of Mid Ohio certify the overall MO schedule- we go though this every year. Our date change is because Indycar took our traditional July date because of the Olympics and TV. Its called dominos.
10-4. I kinda figured...having been part of a car club that has similarly been pushed around there...Quote:

Brakes worked fine the rest of the way home with the trailer on the back even though the light stayed on. When we got home and detached the trailer, the rear brakes immediately started locking up on the gravel driveway and the fronts appeared to be not working. So the fact that the rear brakes are so large (1-ton axle and huge drums) saved our butts. I haven't had the time to diagnose further yet - too much other stuff going on. Probably a line leak - almost all the brake stuff, except for master cylinder and rear wheel cylinders, is as old as the van - 46 years. There is almost no rust anywhere, so it's likely one of the rubber lines.
Have I mentioned that in anything that matters, I am VERY lucky?
I posted a new thread on this in the Trailering and Towing section...
IIRC, a few years ago Atlanta dropped off the schedule;Quote:

Correct me if I'm wrong, but I believe that's the gist of it.
Didn't they race there just a couple of weeks ago?
yup...."at a criminally expensive track to rent" with mediocre turnout. I still love the track, but...
It's a shame, IMO, since I love racing at Road Atlanta (and at Watkins Glen), but FRP has got to at least break even to stay viable and provide us with a great series to race in. So I get it.Quote:

Different locations on the truck but both at plastic clips to the frame.Quote:

I note you did not have fluid loss which clouds your issue. I have heard of the pig tail section below the master letting go gradually.
The 97 now has copper nickel lines front to back.

On my 1999 Ford F250 the lines rusted through after 6 years and in their infinite wisdom they decided to go with a single reservoir for brakes versus the old design where front and back brakes had distinct reservoirs. :mad: Fortunately when I lost all brakes I was able to swerve into berm versus smashing a family in a mini van. I ran all stainless lines front and rear. Someone please tell me the rationale for the change in master cylinders and how that got by the safety gods.
When I get the van on stands and wheels off to do my annual maintenance (rotate tires, grease 22 fittings, lube the leaf springs, change oil, oil filter, AF, etc.), I'm sure I'll be able to spot the failure cause. I'm guessing one of the front rubber brake lines gave up the ghost after 46 years - the fluid was down in one reservoir section slightly from totally full, but if I hadn't had the issue I would have thought nothing of it. We had done several very sharp turns (lock to lock in both directions) in the motel parking lot just before and the extreme flexing in a cold morning was likely the last straw.
Had a motorhome about same vintage as your van. P30 chassis which is similar to GM 3500 stuff. Well had strange brake issue and turned out to be one of the front rubber line. Nothing you could see from the outside. But was failing inside and would restrict flow. Could explain you failure. You pushed down on the brake and fluid went to front brake but was restricted from returning due to internal failure. You were able to pump up as pressure from the pedal is more then the return pressure.
Just a thought

Have had the same internal blockage on GM flex lines 3 times on two different vehicles.
Tough to figure out until you try to bleed the side that is not getting any brakes and no matter what you do no fluid will come out.
Researching it found out that it is not all that uncommon on GM vehicles.
Does sound like a line failure might be the cause - whether it is a blockage, or one sprung a leak, we'll find out when I get it in the air and I look more intensely for issues.

That's a possibility, but multiple brake applications (VA to home - Bath, OH) after the initial incident did not result in another low pedal or more (any) fluid loss. So I will investigate every possibility until I find the culprit. Haven't had time yet to diagnose.Quote:

The latest thinking is that it was the delay/proportioning/brake -failure-signal valve that caused the issue. The question remains, though - WHY did that give the initial VERY low pedal ?
I started a new thread in the Trailering and Towing section and I will post further updates there. Link to that thread:
