who  can  tell me  what my trouble  is  on  my  65  chev  (  l ets say  it s a  65 Laurentien   ok   )  

so  when  i brake  sometimes my pedal  goes right down  to the floor

if   i pumpit  i will get back my presure  , this  happens  sometimes

and my  pedal does sink  if i hold it  down  firmly

how about  a master cyl  rebuid  kit   , would that  do  it

note  in 65  these cars had single  line  system , wich  my  car  stil has

 

thanks   !

 

quick fix,  buy the reman... bench bleed it , an your back on the road in 30 minutes...

Put fresh brake fluid in and completely bleed the system after you get the master sorted out.

 

hone the bore with a wheel cylinder hone. clean it out very well, check for rust pitting.

i dont have a hone , is there an other way to make it nice ????

i guess a hone is not to expensive ?

thanks a lot for the info , i will pick one up tomorow

i checked the inside of the cylinder and it looks nice , but with some light surface rust though , but no pitted rust

there is one thing that is strange , i have GM orig chassis shop manual and i found an exploded view of the master cyl. i wish i could scan that page , but my scan is not in operation yet on this printer/ computer.

this picture shows a seal that would go right before the piston retaining clip ( after there is the piston assembly etc ) actually this seal is not in the cylinder everything past the retaining clip is in the cylinder , this seal would be between the outer cylinder ( cyl extention ) by the mounting flange to be fixed to the fire wall)

anyways, the shop manual shows that seal but my master cyl i dismanteled does not have it , either does my kit ( N O S ) i ordered

i figure there where some with and some without this seal in that production year ??????

my answers to 67 poncho has 3 words to it

YOUR DAMN RIGHT !!!!!!

&?%&%?&%?*(( (((( !!! 1 can t find a hone ( called 2 stores today ) i think i might get one tomorow
2 my wife and kids will not let me in the house because of my bad smell from
my parts cleaner tub it is soaking in
3 finally i just wanted to experience this once , but it is so faster and simpler
to get rebuilt unit for 25.00 more !
4 my time is limited these days , im am in a busy period of the year ,
( landscaping )

anyways...........live and learn !  , (   i have tons of work  to do on the Beaumont !)

i have to add one thing after all these words , i thought i would rebuild it also with the idea of not putting it in the trash , these days we are putting everyyhing to waste and we dont fix things lke we use to.

but after re thinking this over , the hell with my idea , my old one would of have been rebuild.................by the same kind of patient guy like me in a shop , but with all the facilitys

like i said live and learn

got to go see if i can get a hone !

well lucky me , i called a couple of places , and asked a couple of buddys , and no results

so i drop by my local service station tonight , and i ask the owner if he has a hone and could do it to my master cyl

he tells me whe dont use those anymore , we replace everything now , and no longer rebuild anytyhing on place

he tells me i dont think i still have those hones , but checks in his drawers , oh i have one  and  it fits right in there , and you can have it

sir you just made my day , sometimes we are surronded by good people...as simple as that !

also got my steering box out to have the pitman shaft fixed , the shop i wil take it to chromes the shaft to makes it fit back in place , first time i hear about that , it has an up and down play on the shaft.
