Reasonably priced BIG BRAKE alternative that fits in a 15” wheel

Not meaning to insult, I’m always looking to help guys out in the game with affordable ideas, I’ve been building cars since the 80’s and it’s getting pretty expensive for a lot of good people to get in the game without overpaying or getting hosed, I’m not looking to sell anything just passing on to the others what makes hot rodding fun, mix and matching with simple tools. If people give me ideas I’m willing to look into it and pass on what I learn.I hate that this has become a game of the rich with their overpriced and many times overrated parts.
