Hi AidanDawn,
You'll need DOT-3 brake fluid, a wrench (10,11 or 12 mm), 1/4" air line for fish tanks, a mason jar.
Open the hood and look at the firewall in front of the driver. You'll see 2 sets of plastic canisters. They are vertical on aluminum assemblies.
Now open another browser and type in "roadster brake master cylinder" and look at the images.
Yours should have 2 plastic containers (as it is a 68). The front one is for you front brakes, the one closest to the firewall is for the rear brakes.
Pop the covers off of both.
If YES then do this. Remove both front tires and put car on jacks. You will see the rotor (the round metal that spins). There is also a brake caliper.
In your other browser type in "datsun roadster brake caliper" and look at images.
The caliper on the back side of the wheel has a small bolt thing on top with a "nipple" thing on it (it's called the bleeder). Put a piece of 1/4" tube on that and loosen it. You can use air line for fish tanks to do that. Put the other end into a mason jar (have it rest on the bottom of the jar). Now fill that master cylinder (the white plastic) with brake fluid.
Pump the brake. You should see the level drop in the plastic container. Look at the mason jar. Did anything come out? Keep filling & pumping. Don't let the master cylinder go dry. Once you see clean brake fluid coming into the mason jar, tighten the bleeder.
Pump your brakes and look into the master cylinder. Do you see black gunk bubbling up or air bubbles? If so then you need a rebuild kit for that (not expensive).
No gunk but wheels don't stop (spin wheels then press brakes), then you need a caliper rebuild kit for them (1 kit should cover 2 calipers). These are cheap.
Congrats on the car. I just gave my daughter (shes 18) a 1966 roadster that she's working on and learning as well.
