Bench Bleeding M/c In Car????


Go to solution Solved by JIPJOBXX,

Thanks for the encouragement and tomorrow morning back to Les Schwab and make up some dumb story about why I need my car to be rebleed.  I got rebleed the the system for the 1000th time today but it still has air stuck in it somewhere?  Like I said befor I had the M/C port adjustment out of position and the people who were working on my car could not tell the difference but I sure did when I started to drive the car home.  The brake pedal was rock hard and by time I got home my brakes were on full arrest!  Good thing I only live about 3/4 miles from the shop that did the work.  I know I'm in for a blast from the manager but hay I took it in to have it bleed and checked out and poop happens.  So maybe the end of the road is in site once again and brakes are us will be back again.  I can drive the car but it still soft pedal.   Now here is a mysterious question and it will state it in red!!!!!!!!!!Why or what happen last week to  make my brakes lock on all four tire just once or twice as I took it out for a test.  They worked perfect and then parked it and back to square one and soft brakes!!!!!!!!!!!!!!!!!!!  Sound like my car burped a gas bubble somewhere and then had gas again!!!!  Got to laugh at this as my buddy he was me and he thought the problem was fixed and then blam back to round house and bad brakes!!!!! Oh well nice day outside and got my car all cleaned up and tool somewhat put away.  Jon

Took the car back this morning and the manager said that the master cylinder needed to rebuild!!!!!! The only thing good about this action is that I got it out of there and down to auto shop and its been there all day.  Master Cylinder my foot I just rebuilt it and its just like new!  So when I get the car back from the shop I hope they have this problem figured out.  Oh yes they are power bleeding the system again and had to bower my special adapter cap that I made up to do part of the manual bleeding I did myself.  Anyway I have just gave up and now the cash machine is in order.

I would suggest having a qualified shop test your brake system and let them tell you what is wrong. You have done plenty and need to trust you are done. If you continue, you may have brakes that fail and hurt someone other than yourself. Gotta keep this car stuff fun...its Ok to write a check sometimes.

So...................... then why would you possibly leave the vehicle there to have the master rebuilt if you just did that, and feel that it is not the problem  :confused: :confused:

 

 

EDIT: sorry, misread your post. Thought you left the car there for work :cool:

I did not leave the car there as at that time I decided to take it to a real mechanic not just tire changers.  It was nice not to have my old car in my garage yesterday as I got a chance to back up and clean and organize my tools.  I did get a call from the shop I took it too yesterday and owner was wondering if I had a spare cap for my M/C as he had every size but the right size to fit my car.  Well fortunately I had one with a special fitting for the bleeding operations that I had gone through.  So I took it down there and just left it there and had a nice day doing this and that.  I have had a lot of cars in my life and not one that has given me the trouble I have had with this old machine brakes.  So maybe today the riddle will be solved and I can move on to another project!  Oh about being safe that is number one in my book and I always double check myself just to make sure everything is done right.  This is just in my nature as I'm kind of worry wart person.  Oh well its beats the option to be the opposite.

Don't write the check till the brakes work right!

Well I think it bad luck for number two Don.  I got a call from the shop I took the car too and the supervisor stated to me that one of the bleeder plugs broke oft!  Yep it broke the casting that the plug goes into on the brake cyclinder.  I think they might have been bleeding the system with pressure and then after 70 years the casting just broke or tighten it too tight.  I could tell it was an old fracture because of rust where it parted from.  So 260 dollars po orer I ordered all new brake cylinders!!!!!!! Oh well the black hole keep on sucking my money into it.  Now the car sit on a lift waiting for ups to bring to my door the new cylinders.  Just glad to have the car out of my garage for a few day :Ds as that way I can get other things done.  I built a workbench today out of an old hard core door that I had laying around and now that project is done.  Any comments about my luck?????????????????????? :cool:

Maybe, just maybe, you've discovered what was going wrong with your brakes.

Have you done a minor brake shoe adjustment, after doing the double bleed and Acme 1750 adjustment?

When having replaced the shoes (in pairs of course - per axle that is to say). That is what is known as a Major Brake Adjustment.

One should then use the Cam Bolts on the back of the wheel housing to obtain a higher pedal. Assuming you have no leaks and have bled the system 

correctly then a minor adjustment is at hand. Jack the car up (wheel off the ground) spin the wheel with one hand while adjusting the Cams until just making contact

then back off just enough that the wheel spins free again. In this way you will obtain the least amount of shoe clearance and the brake pedal shouldn't travel

down so far before engaging the drum. Go around to all 4 wheels - same proceedure. You should then test drive it and apply brakes hard to be sure its not pulling to one side or another.

The best brake pedal travel should be about an inch from the top of travel when the shoes engage the drums - that is the good high firm pedal you are trying for.

Well we shall see what we shall see!  This was not the first time that the bleeder was tighten but maybe they got on it with a little bit of more strength.  I wore out all the new old one I put on there a month ago and replaced them with new bleeder two days ago.  Maybe just the combination of the two caused the casting to fracture?  Kind of glad that it happen as this could have been a problem down the road.  No one ever states that you should replace your brack cyclinders if you can hone them out and they seal than they are good to go.  But now here is a new way of thinking????????? Maybe with all our old cars we should replace the brake cyclinders after 70 years because of this fracture conditions?  My mechanic wanted me to replace the M/C but it fairly new with a stainless steel sleeve and new internals just installed last weekend.  I trully think when we finally get the air completly out than the old brakes will work as they are suppose to.  What else could I replace new shoes, new brake cyclinders, new hoses,  new tubbing and a rebuilt M/C that works under  pressure!  So that it for today (Oh yes all those new fittings also for connecting the tubbing together)

Sorry about that Tom I hit the wrong button and yes all those devices have been used!  Funny if you can figure this one out that last week the pedal was almost resting on the floor but I wanted to see if i pumped it up than what would happen?  So I backed out of the garage and headed down the driveway and all four wheel came to a tight stop and the pedal was just where it should be at.  But when I put the car back into the garage the pedal went down (air) and so far with all the fooling around I have not got back to that point again :)  Jon

I usually won't hone out real old W/cylinders. Not worth the risk and leakage hassle. I find good qualityUSA which is about impossible now days or have them re-sleeved.

Take a box of donuts to the repair shop each morning to make them really like you and your car till the job is done and works right! It might help on the final bill too.

You are so right and I hope the ones that I get in the mail will fit the bill.  Dam got almost 500 dollars in these silly old brakes!  Oh well not bad for a car that I have had for almost 25 years!  Guess by the time I'm finished with this fiasco I will have maybe 700 or 750 into the stopping part and labor of my old dodge.

Brakes still not working :) The shop I took it too have done everything that I had done and they will pump up but then drop back to the floor.  Guess its now to the master cyclinder and well thats been rebuilt over this long process but what else can it be.  New everything in brakes go figure? So I told them I would take the car home and take out the master cyclinder and take it over to the shop that rebuilt it 15 years ago with a stainless steel sleeve.  Could this be the problem? who knows but this mystery will be resolved some way. some how.  I can adjust the main piston rod in the master cyclinder to a point where the brakes will work but its not within the parimiters of what is called out in the manual.  I kind of laugh when I think about this problem as I have had so many people involved with this situation and so many people who are so called experts.  But no one has come up with the answer :) So if the shop cannot get it to work tomorrow I will be taking the old car home and removing the M/C to have it checked out at Hagens who rebuilt this unit.  After that I will reinstall the cyclinder and take it over the shop that has been doing the work and cross my fingers that something has been fixed.

I'm beginning to beleive my car has a hex on it!!!! As you guys know my car is in a garage to be checked out for the brake problem.  Well the owner this past weekend was loading a car on a trailer and somehow it got loose and ran over him!!! He is over in Seattle now with a broken hip and other stuff.  My car is still in his garage and just found out today of what happened.  I really do like the owner and he is not a young pup to have this happen to him.  As for my car well I just told the mechanic to try and figure out the problem with air in the system or whatever but not to get too involved with my old Dodge as I can live without my car but I hate to see a friend in the hospital and probably will be hurting for a long time.

yeah...Christine's grandmother...bah..!!!...only thing there is someone was not on their game loading anymore than there being on their game in troubleshooting and fixing brakes...

 

if your car was possessed in any manner it would I am sure makes itself capable of stopping...

 

OR......

 

 

there would be a hundred lawsuits for it over milking the cows in the neighborhood

Sorry to hear of the mishap. I do suggest you remove your car from that guys shop as I am sure that once he returns to work that he will never want to see your car for the rest of his life.

The president of the NW region Chrysler club also got run over by a valiant ragtop on ramps this last week and is in the hospital!

Be careful out there working on your cars guys!!!

Someone here stated by changing out the brake lines that my troubles would be over and as far as I can tell it was just a waste of 100 dollars and a lot of time.  No noticable difference in the brakes.  Oh well lesson learned and now to the next lesson. 

Posted

So now its back to square one and get my car home remove the master cyclinder and put in another kit.  From there on everything is new in the system and I mean everything!!!!!!!!!  Oh well I got a cherry old motor home to drive around in :).

Where would you guys start at if you were in my shoes?

New brake shoes, new wheel cyclinders, new spring, new rebuild kit for M/C that has a stainless steel sleeve, new plumbing, new rubber hosses and shoe fit with in the tolarances of the specs given in my tech manual.  Any more suggestion???  lets hear it from the peanut gallery!!!!!!!!!!!!!!!!! (the pedal will pump up but then go back to the floor) Air or not to air is the question?
