Brakes and Bleeding

[Jim_Gruber]

First pump of the pedal goes almost all of the way to the floor. Second pump firm pedal. Third pump all of the way up. This appears to have been a new Master Cylinder on Bugsy IV along with all new Wheel Cylinders. I added new hoses all around. Shoes feel about as tight as I can make them. Have bled two or three times. Today by myself with help from Mity-Vac. Is there anything with the pedal adjustment screw I need to worry about. Not going all of the way back and allowing MC to refill properly. Looks ok visually and there is far more than 5/32" of pedal movement before brake rod begins to move. other than finding a Brake Bleeding Assistant today what am I missing. I've never had an issue with bleeding brakes before.

Ok worked and worked and now have a better pedal. Still not like having discs but I at least have a 1/2 pedal that is firm on first p[ush and second push all the way up. Discovered rear beehive spring rolling around inside the drum. All bent to crap. Need to dig up a spare from someone local.

I know you said you had the shoes adjusted as much as you thought you dared. However, the symptoms are consistent with shoes that need adjusting. Remember the wheels should not be able to freewheel multiple turns when spun by hand. They should top rotating within about one revolution and there should be mildly audible scraping of the shoes on the drums.

 

[Jim_Gruber]

There is mildly audible scraping for sure. Need to get another beehive spring from local LBC Shop on Tuesday, put it back together and go drive.

 

[Jim_Gruber]

Spring obtained, reinstalled, back in service. Off Jackstands tomorrow, and a real test drive for Bugsy IV


BTW - Ohio License Plates arrived that read BUGSY IV He is now legal.

And how were the brakes? Did they bed in a little on your drive?

 

[Jim_Gruber]

Got 1/2 a block. Major clunk noise in driveline when shifting. Not a little, a major clunk I heard and felt. Guessing Driveshaft bolts not tightened down. But **** did Bugsy feel Spritely with a whole lot of oomph in second gear. Brakes still an issue, will take things up another notch all around and see if that helps and try some gravity bleeding. Time to put back up on jackstands again.

Oh and if all else fails, Bugsy could make a trip to visit Steve Miller at MG Automotive, LBC's only, 4 miles away. I do have local help available and like I've repeated sometimes the best tool in your checkbook is your credit card. I need some professional help to dial in timing and carbs but they feel pretty good right now. And advice on brakes would be good at this time. He did tell me to check fitting of brake rod with spring stop. Fun, fun, fun. I want to go drive Bugsy. Temp Tags are now mounted, well actually taped to the rear of the car.

Re: Brakes and Bleeding - Found the issue

View attachment 44879Found the issue - Team Can someone tell me what they see wrong with this photo. Issue with Brakes will be fixed with the addition of two critical parts. My DUH Moment in finding out another thing that the DPO did incorrectly. And I know I have one of these available. Just need to dig it out.

Who would've thought to look at that. Now to find one and a small cotter pin in the parts box. It's always the little things. Details, details, details. Now to figure out clunk when shifting. Swapping the driveshaft is on the agenda for Saturday. Bill M. says he can reach in there and his arm of long enough to guide in the driveshaft. Not sure if he is suggesting coming in from the length of the tranny tunnel ala Breeding Mares a Dirty Jobs Episode or coming in via shifter removed access. I don't think my size 31 in-sleeve will get there from the end of the tranny tunnel.

My sleeve is only 29 so yours should fit fine

[Jim_Gruber]

So you are reaching up the tranny tunnel rather than going in from gearshift lever correct.

It is like when a vet reaches into a cow to assist in the birth of a calf.

 

[Jim_Gruber]

Nelson I'll be attempting to do just that tomorrow.

Clevis Pin and a Cotter pin did the trick. In fact I found the wayward CLevis pin in side the pedal box under the spring. Looks like DAPO did install just forgot the cotter pin. Strong Pedal, firm, have not driven yet but I believe issue is fixed. Working on DS Door finally figured out issue with door closing was a bent hinge. Now it aligns and opens and shuts correctly. Details, more fettling. Next major challenge will be generator lamp being on. Could be simply a polarity issue, I hope.
