Master Cylinder Nightmare

Man those resevoir tubes on the top of the MC are a PIA! Got them in put everything together added fluid, no leaks.
My question is i know the resevoir tubes are not in all the way( I Think).
I never heard a snap or noise indicating they were seated properly when i pushed them in, does the fact that they are not leaking mean they ARE in all the way? They were so hard to get at and work with i never want to do this task again.

My friend, you must possess the Kung Fu grip to get them in under the car with ZERO leverage. I'm asian and had same fun experience, but no Kung Fu Grip. First time "thought" I seated them properly, one week later small puddle of break fluid on ground as fluid weeped out of the reservoir holes. What a pain in the A$$. just press down on the rubber grommets and if its not seated you will have wet fingertips.

I love the service manual "just push lines back in". The cure for me was to release the lines from the reservior and pull them out from the bottom. Then with all the leverage I needed, I inserted the fluted hard line in very easily and thread the lines back to the reservior This time it took me about 5 minutes instead of 2 hours.

Don't worry as everyone who has done a MBC replacement has had lots of fun . . . NOT! As that Michael Jackson song goes . . . "you are not alone, I am here with you"

you can tell when its in, you need to "feel" the lip on the tube pop in the rubber grove. i had to loosen the cyl. from the fire wall to get a better grip, and it still no fun. and be careful, the line is over 100 bucks now, for each one.

Ash is right - Easier yet, remove the whole reservior and pull the lines down before you install. Makes it much easier.......

My whole body hurts from this job, and that is a great idea, pull the lines all the way down then hook up and push MC up into firewall. there aint much room for that either. Why didnt they just use compresion nut and farrel?

Because, that would be too easy, how else can you get friends over to drink beer, lie under the car, curse with you, sweat with you, drink more beer , curse, bleed the brake system, bleed from scraping fingers on metal, just a day full of fun.

The fact there are no leaks in a good sign.
When I had those seals improperly positioned, brake fluid poured out all over the place.
You are probably fine.

I put it all together left the lines filled and bleed the brakes. I have no leaks at this time, but its still on stands and hasnt been road tested i hope i got it, I dont have it in me to do this again.
At this time.

GOOD INDICATIONS SO FAR.

Stomp on the breaks then go back under and reach up to the grommets where the hard fluted lines inserted in to the MC and push the grommets down hard and see if any B-Fluid on finger tips as should be dry.

Yes, doing it twice is not a lot of fun, doing it right should last another 30 yrs. or the next caretaker of your car can "experience the joy"

Good Job!
