Brakes. Stopping this thing

[ERA174]

I'm assuming your Contemporary Cobra is new to you? If it is, and still in it's race trim, the brake pads may be the extent of your issue. Race pads need a lot more heat to bite, not something that works for a street driven car. If before you aquired the car it sat for an extended period, you may have other issues you need to address. The full extent of the solution may entail, flushing & replacing brake fluid, rebuilding/replacing calipers & master cylinders, deglazing/replacing rotors & replacing brake pads. If when you put your best emergency stop brake force on the brake pedal it doesn't pull to one direction or lock up some wheels and not others, I would start with flushing and replacing the brake fluid, deglaze the rotors and replace brake pads with street pads. If, you have some wheels locking up & others don't, or pulling left or right, then I would also rebuild the brake calipers, cheap but a little more time intensive then buying replacements. I would rebuild, you may need to buy replacements farther down the rabit hole, if you find what you have doesn't work for your intended use. Your issue is probably not a complete re-enginering/replacement of your existing system. Take the time to evaluate what issues you have and what the solutions are to those issues, rather then re-inventing the wheel.
