    Default Bolt size for wheel cylinders

    Thought I saved the old ones, but didn't.
    Bolts to hold the rear wheel cylinders on- are they 1/4-20 x1? It is an 8.8.

    Once I get them I can put the rear brake line on the axle assembly and bolt it in. Hello roller!

    That sounds more right than my guess. I could always take the cylinder to town I guess.

    Thanks! Maybe I will grab a few of those on the way home just in n case. Save me 35 miles of driving.

    I am not 100%, but the mounting bolts are not very big, I believe the 1/4x20 size may be correct. I seem to remember the bolts require a 7/16" socket/box end to remove which would normally be 1/4" bolt. If nothing else, grab a couple of each and you should be covered....... Unless they're metric!

    They're 1/2-20. Crud. Looks like I will stop again on the way home from work tomorrow. Oh well. I got a bunch, but they're too long.

    WOW! I would not have guessed that!

    Then again I don't see how they are 1/2-20, but . . . .
