How much do those bleeder tools cost and where are they available to purchase??
Most brake bleeding tools are available between $25 to $50. There are several companies that make them… which is the best? I haven’t tested them side-by-side as my “Mity-Vac” has been doing the job for nearly 30-years without failing. Do a Google search for “Vacuum Bleeding Tool”, and you’ll discover a multitude of choices and price ranges.

When I hook the vacuum pump to my bleeder fitting, it sucks air in past the bleeder threads, so all I see are air bubbles continuously. Is there a way to prevent this?
This can be a problem on some cars, try not to loosen the bleeder as much and see if that helps. If you are pulling a good amount of fluid through the system with your bleeding process, the small amount of bubbles you are seeing in the tube is likely not an issue as the air that enters is being immediately evacuated. You can also complete your bleeding process by having someone step on the brake pedal, while you open then close the bleeder before they release the pedal. You’ll know you have it right when you have a good firm brake pedal, that DOES NOT require you to pump the pedal to get firm braking.

I had that problem so I wrapped the bleeder threads with Teflon tape. Seemed to help a lot.
The Four-Wheel Anti-lock Brake System (ABS) is an electronically otearped, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. When anyone of these malfunction the ABS Light will come on. Reference:
