Clutch master cylinder nuts are ovaled on one end???

That is intentional, they are lock nuts.

Thanks for the help guys-

I asked at the parts counter about the nuts too... I was hoping they were wrong but I kinda knew they were made that way.

Try doing this with no air tools and just yourself and 2 of the $10 3/8' socket sets sometime lol ;o)

Fun inventing ways to jam one socket set against something around the firewall in the engine compartment while you loosen the nuts inside with the other socket set.

I dropped the tranny in my 76 camaro by myself to change the clutch a long time ago when you could rent a lift... to say the least I was surprised how heavy it was hehe... but didn't drop it. Swapped out the entire front body section with new parts and then sent it to get painted.

Life's boring without a challenge now and then.

Using an air tool on this type of nut can cause it to damage the bolt. I do it by hand, but my socket set is pretty good. Flare wrenches protect the hydraulic fasteners from damage when torquing, so next time, it's not a nightmare. If you intend to do your own work, quality tools are a worthy investment.

Well I found a small tip for ya maybe... I picked up a 16mm open-end wrench for a buck at the hock shop... I slide that onto the left-hand bolt head inside the firewall and rest it against the brake master... then I tighten from inside the vehicle with a 5/8 (close enuf) spark plug socket on a 3" extension... on the right-hand bolt it's close enough to the body of the master that it holds fast. I picked up a 16mm socket for a buck too, but had to switch back to the deep socket pretty quick.

It went back on easier than it came off except for a stupid bracket inside the cabin running from the firewall to the side panel by the firewall (wtf?). The holes wouldn't like up so I had to rig some wire ties to hold it in place... I had to pull the washer bottle too :o) But no wobble extension needed.

So I get it all back together and I'm ready to work on bleeding... I'm pumping the pedal...

And the *%$@#*!@ piston pulls completely out of the master... it just dropped right the &%#$ out :o(

I am not a happy camper lol. Gotta call O'Reilly in a minute.

And I was liking this new master cyl... has a translucent plastic reservoir with a bayonet cap... the body looks like steel instead of aluminum. But man....

Grrr.... &*%#$@^!*

ROFLMAO I gotta remember that :o)
