Ahhh fun times, I think this White car does not like to travel outside NY Big smile
Thought the pedal felt a bit funny while running some back roads with Shimer's, and Mooney's friday evening. Sat morning on the way to fairgrounds brake light came on.
Looked under car as much as you can while on the grass and did not see any wet spots. Frank went wheel to wheel and put his fingers in the wheel slots. Rear drivers side was black, not wet but black.
Topped off the rear master as it was down about 1/2 inch.
Drove it home yesterday being very aware of my surroundings. The traffic on 81 was very light and we had no problems.
I placed an order today for new O-ring rebuild kits for all four calipers, four new SS brake hoses ($19 more than stock) new rear pads as I'm sure that side is wet, and a rebuild kit for Master cyl.
I figured the system has not been flushed clean in 25 years. I'll start tearing it down tonight, blow out the lines, run some brake clean through them till their looking clean. When parts get here I'll put it all back together.
So any little tricks or "To Do's" I should watch for along the way?

While I'm at it list

  • clean and polish rims
  • rotate tires
  • grease front end
  • spray eastwood rust proof inside frame rails
  • paint calipers
  • sand and repaint black slots on the wheels

sounds like fun - why not have a little more fun and repack / replace front wheel bearings, races and seals while you're havinig fun. Did mine a few months ago with all timken bearings, races and seals for about $60, nothing like a little grease all over the place.
 
Sorry I missed you last Saturday at Carlisle, just ran out of time ..... Cry
 
Good luck with your project!

I know that the propotioning valve is supposed to keep the rear brakes from locking up, but was wondering if it might be restricted. Just a thought!

Dennis, that may not be a bad Idea, it only has 20K but Its easy enough to pull the hub and take a peak, cost nothing to clean and regrease.
So you did not make it to Carlisle?

No locking up, once you pumped the pedal a few times it was ok, I just gave myself plenty of stopping distance and kept an eye out for trouble.

I removed the McGuard wheel locks (once I found where I hid the key) loosened all the lugs. One rear lug was spinning, must have spun all the grippers off the stud and she was just turning with the lug nut. WD 40'd the wee wee out of it let it sit ten minutes and came back at it in fast jerking strokes (Marshal) it came loose. Just grilled up some chicken so i'll have it up on stands tonight.
Is it possible to get to that stud to replace it without removing the rear rotor?

Look what I found...only rotor with no rivets? why?

Yes, I made it over to Carlisle on Saturday and just ran out of time and forgot to stop by and see you guys. Not that I don't think of you guys often, but this was my first Carlisle and I had no idea how big a place it really was. Next time I hope to be a little better prepared and not walk in so many circles. Wacko

No.....Disapprove

At least the rotor is not riveted anymore. Once you get the rotor off, you cna snake the old stud out, and a new one in. It ain't easy, mind you, but it am possible. I've had to do it on my '74 a couple of times....dadgummit....Angry

This may sound warped but you all will understand what i mean.....
ebowoman (my wife) asked me last night..... " Do you really enjoy working on this car?"
I replyed "yes I do"!
"I just don't like when it acts badly on road trips."
Some people talk about a scheduled PM program for their cars like flushing out the brake system every so many years. Does anyone have this kind of schedule?
It may be the way to go and maybe cut down on the surprises.....?Confused

Every spring & fall I go over the car & look for stuff that might be questionable and I try to take care of things before they happen.
You can't at it as a low milage car, it's over 30 years old and that is what determines alot of issues that come up.
You also could jack up the radiator cap & put a C5 under it.
Too bad we weren't closer, could give you a hand, good luck with it.

Well I have next week off for spliting wood, but evening and rain days will be working on the vette.
Slow and steady, and yes it's 32 years old, I keep saying that. LOL

Removed both rear calipers, SS line's, and brake hoses. Took rotor off without to much trouble, knocked the stud back.......and spent an hour trying to get it out.
Removed star adjuster and rotated it to the bottom.....no way... its about 1/16 to long.
I know I could get it out but I'd have to shorten the new one or make it look like a nascar stud to get it back in. The grips still looked decent on the stud so I cleaned it well and slapped on a bit of JB Weld and reseated it (sorry Joel) will let it dry over night. I'll just put some never sieze on that stud and try not to over torque it.
That's it for tonight. (heh i'm on my own clock!)

OK, the Brake overhaul is complete and the test drive a success.
I was a bit nervous about removing and rebuilding the Master Cylinder. All the horror stories about getting all the air out during bench bleeding. It was actually a pretty easy job!
I bought one of those 6 dollar 1 man bleeding kits and it worked great, even used it to bleed the calipers.
ebowoman helped me with the final pumping until we had a hard pedal, went around maybe 6 times.
I took quite a few step by step pictures and will put an article together.
 
Now it's onto "Project Red" but that will be another thread......
