    Default Wheel cylinder

    Hey guys
    So found out this past weekend that my rear drivers' side brake is leaking fluid. My mechanic suspects it to be the wheel cylinder. I have a question for you all. Is there a difference between the 76 wheel cylinder say one from a 77-78 280z?

    Thanks
    Jan

    I just checked NAPA online and from production date 9/76 on, it appears the '76 has the same part number as the 77-78. The note for ATM 9407 says "From 9/76"

    Your mechanic should be able to compare the parts visually if he can get one from his parts supplier.

    Afraid I don't know what happened in 9/76, just going on the parts catalog here. If you check MSA, it groups 76 with 73-76. My 73 has the parking mechanism integrated with the wheel cylinder, the 77-78 does not look like this is the case

    Thanks for the response Andy. I emailed my mechanic some information maybe he'll have a better shot at figuring this out.

    Do have one more question. Are u-joints on 76 280's replaceable. According to MSA they are not but according to NAPA they are. Anyone know?

    Any u-joint can be replaced.

    I'd have to agree with this. The u-joints are available for the 76. I don't have personal experience with the half shafts but I don't know why you couldn't replace the joints.

    The reason you can't replace them easily is the u-joint caps are swaged into the yokes- take a close look, you'll see what I mean. You probably just need to take it to a shop, where they will know how to deal with it, and what to replace them with.

    good luck

    You do not yunk it out. All you gotta to do is to hit the yoke next to the joint, so joint slowly pops out. Please do not forget to put some WD40 to make it happen quicker......
