Time to replace wheel cylinders, would they be metric or sae?

I wasn’t able to find definitive information from my search, 82 & 83 sae 84 maybe, 85?

Im working in a single car garage, so I can’t take the car apart to find out for myself.



Thanks for your input

 

Most likely, metric. No guarantees.

 

My 85 Z28 has metric brake lines, so I would agree, most likely metric, but anything is possible, especially if they have already been replaced before.

 

either way, if you buy new you can use the innards to re-build the ones you have if the brake line fitting is wrong.

several years ago I tried to acquire a set of the older, pre-85 cylinders but kept getting the newer ones that wouldn't attach to my brake lines. wound up just re-building the old ones.

 

Thanks guys, they were metric - the factory lines had 12mm headed fittings.

What a peach those retaining springs are!

Almost 3 hours for the passenger side, about 25 minutes on the drivers side. I made up a sleeve from an old motorcycle exhaust (couldn’t find a socket that’d fit in the opening and slip over the wheel cylinder. There is a brace on top of the axle which can be used to lever against, put even pressure on the retaining spring. Once you hear the most satisfying click ever identifying one side has dropped in, the other can be tapped in with a small chisel and hammer.
