Nice SA! About time some folks on this site show a little 1st gen love! Those waffles still
look new.

I would replace the master/slave soon. Probably a lot of corrosion in there. Do the hose
too at that time. How does the brake fluid look? You should probably start collecting all
the rubber hoses to replace the stock ones. At this age they are all probably deteriorated.

They're in pretty good shape, but not perfect. There's some oxidation where wheel weights were installed in the past and one of the center caps has paint peeling. Still, they're not bad for their age and hopefully they'll look better when I get a chance to do more than just a quick wash.

The brake master cylinder was replaced in 1988, which is why I think that was the last time the fluid was changed. I ended up flushing about 32 oz of new fluid through the brakes and clutch. In the end clean, clear-yellow fluid was flowing from all the bleeders. The brake and clutch feel is MUCH better. Right now I just want to get the 25,000 mile maintenance done but I will definitely be keeping an eye on the brakes. I'll probably rebuild the brake and clutch master cylinders, clutch slave cylinder, front calipers, and rear drums and replace all the soft lines, rotors, pads, shoes, and associated hardware at some point in the near future just to be safe.

Hopefully it will stay that clear yellow color for a long time. Two things turn new brake fluid into that crappy dark brown color - (a) Absorbing moisture in the air over lots of time, and (b) Residue from all the deteriorated rubber seals in the MC & wheel cylinders. So in about month, if you notice the fluid color is becoming noticeably darker, you know that you got (b) going on, and you might want to speed up your plan to overhaul the MC & brake hydraulic parts before something breaks.
