My brake cylinder reservoir has an overflow tube in the side. The replacement one (I got for free) does not. Did they change that along the way? If so, why?

Neather my 72 or 74 has such a tube, I guess it could be a late model thing.
Can't see any problem running it without. |

Early did ..... late didn't
Only a concern if you overfill your reservoir and then push pads back to change them .... it just spills brake fluid on the paint No need for the tube in real life ...... |

They did change along the way.
the later ones without the tube have a chamber in the cap that allows air to get in and the reservoir to breathe (in the same way the tube allows air to breath) I got tired of the tube on my 72 race car always dripping on the track only cars there is a bit more expansion of the fluid than there is on a street car. Thus you have to run the reservoir less than full to accomodate expansion. But I always get nervous and top off the fluid too much which would set up a situation where my breather tube would drip... that fluid would blow back on the bottom of the chassis and eat the paint off of the underside of the pan. On a street car this is not a problem. either will work... just make certain that there is some type of breather brant |
