2020 .. What are you doing today?

Hung eight of these today, my first experience with the Spirolok wristpin keepers, there is a definite learning curve, the first one took me twenty minutes, just to get one Spirolok in. The last was three minutes for the entire assembly. Just as I got the hang of it, I ran out of Pistons! 😃

I got educated with spirolocks in 1976 with a boss 336 pro stock engine. Now, they're an annoyance instead of a PITA. However, I've never heard of one popping out like snap rings under detonation.

I will listen to the live stream from Bonneville this morning.  George Poteet is going to try a really fast pass first thing this morning.

I agree, and not really that hard to put in, once you figure it out. And, if installed properly, they are not coming out on their own! Mine were the double wrap style, just for added fun. 😄 I didn't know they went back that far, it's been a while since I put a motor together but when I did it was the snap ring style I used. Still waiting for maincap bolts to arrive, they were supposed to be here yesterday, then the real fun begins.

Still painting the garage, we got the house done last week.  The west side of the garage is just beat up, especially the fascia which is cedar.  We have about a half mile of open field on that side and the wind really runs hard.

Looks like the nats north at Kalamazoo has been canceled.  I know that is home to a lot of you on the board.  I have enjoyed this event in the past and I am sorry you will not have it this year.

I had a feeling that was going to happen with the governor they have. I didn't register, but I did reserve a motel room

My wife came home from the food store last weekend... she tells me the Halloween supplies from food to displays are in stock.  Seems early.

I am continuing work on the brakes on my 54 chevy with 4 wheel power disc.  I have narrowed the problem to the rear calipers.  When I isolate the calipers there is a 400 psi pressure difference.  When the calipers are in the system, the pressure is about 700 psi and when I isolate them, by taking a reading at the point where they connect to brake lines, I get a reading of near 1100 psi.  I have tried lots of different bleeding methods, even removing the caliper and rotating it into different position in hopes of removing any trapped air.  At least I have it narrowed down to the calipers.  Time for more pondering. :?

Motel canceled. No one mentioned my misspelling of Milestone in my last post here

^^^^^
We were being nice to you.

I read that the Speed Demon ran an average around 470 mph  with his AA engine ..  with a back door speed of 481 mph.

Purty dang amazing

I thought you intentionally meant 'millstone.' Sorry.

Congrats, John. 50 is a milestone.

My folks hit 58 this week.

Is it a flow (volume) problem or a pressure problem, John?

Is it possible the master cylinder is not displacing enough fluid (volume) to satisfy the caliper volumes when the pistons are extended?

It seems to me the pressure is high when pumping against a "dead head,"  but as the pistons extend, the increased volume of the system is not being supplied by the m/c, thereby causing the pressure to drop.

Of course, I may be totally mistaken and F.O.S.!

Is it possible to isolate ONLY ONE rear caliper and re-test?
