Hey guys, I'm new here. I have a 1992 dodge dakota 6 cyl with a brake problem. The light is on and there was no or very little fluid in the reservoir when I put fluid in. I do have some brake when I get to the very bottom of the pedal but that is it. I've attached some videos with questions.

Where do I get a replacement vaccum booster that is connected to the master cylinder?

Having little to no brake fluid in the master cylinder resevoir caused air to become trapped in the lines thus causing the low brake pedal. You need to take your tires off and check the calipers and wheel cylinders for leakage as well as the brake lines that run along your frame. I can't tell you how many times I've worked on cars from up north that have so much rust that it corrodes the brake lines. As far as your booster, it's dirt cheap and you can pick it up from most auto part stores. I bought mine last year from Autozone for $56.

 

Yes you got air in the lines. First bleed all 4 brakes.
