DIY Cross Kart Brakes ~ YZ450 Buggy Build

Published 2023-06-19
In todays video I make custom brakes for the yz450f buggy by modifying Miata brake rotors to fit trailer 4x4 wheel hubs. We opened up the center bore on the rotors to slide on the backside of the hubs. This allowed us to use the wheel studs to hold the rotors to hubs. Then we ran 3an braided brake lines and 3/16 stainless hardlines. Next we modified the radiator by putting a 45 degree angle pipe on the fill lid. We're almost to the finish line!!

    Since you have the lathe, I would machine the back of the wheel hubs where the brakes are mounted to flat enough to where the rotors have a flat spot to set against. Those hubs are made from cast and the tolerances on where the lugs go in are horrendous. They just leave them as it is as it does not matter what the tolerances are since its just a spot to hold the wheel onto the hub. The wobble that is shown in the video will wear through brake pads so fast even if it is a smooth rotor.

    I love that when Mrs. Red Beard is filming, she holds the camera so very smooth. Some You-Tube channels, while they film, shake their camera way too much and zoom in and out so much and so quick that it makes it hard to watch what's actually going on. Keep up the good work Mrs. Red Beard!! It really makes a difference. Your skills are great.
  • @levipatzer4276
    Hey red beard!!! net time you are mounting up a caliper hook it to your air compressor and it'll hold it right in place for you to weld in, works like a charm!!!!!
  • @AZ-Patriot
    That long neck on there is perfect. It's the best possible fill point for the cooling system.
  • @tmenzella
    Hey Red that disk wave more than my grandma as I leave her house, face off the back side buddy 👌🏻
  • @user-ok4jo2im1c
    That is just genius. Basically spare autozone parts to make a custom 4 wheel disc brakes setup. Never in a million years would i think to myself "hey lets take a rear miata rotor and some cheap trailer hubs and make a custom disk brake setup"
  • @jamesmikesell5458
    Love your videos and truly appreciate the Bible verses you are now adding to the videos also
  • @jessemillsap9387
    I think the radiator neck looks fine and add extra fluid capacity. Im getting Running Man vibes on the cart though..
  • @bodine2537
    That’s a nice ride there, if I’d ever thought of building my own rides growing up there’s no telling what all id be doing by now, I was fortunate enough to have a dad who could afford to buy all my 3 wheelers and dirt bikes growing up, he was a master machinist , if id ever mentioned it I know he’d been able to machine anything id needed, about the only things being built back then were people turning VW’s into dune buggy’s
  • @william49
    I've seen people just use air pressure to operate calipers for mocking up the mount. Also @ the 9min mark it looks like that rotor is wobbly.
  • @CncObsession
    I am hoping that rotor wobble was due to the lug nuts not being tight or even on. Otherwise the hub casting might need to be faced on the lathe. The backside is not a finished side, that is the raw casting. I run those same rotors on my golf cart but use the wheel to sandwich the rotor to the hub.
  • @rwcasto
    You can always use air to compress those calipers 👍🏻. Works like a charm and you don’t have the mess of the brake fluid
  • @memorris2
    I say leave the long neck and if it still bothers you when you disassemble for paint, you can change it then.
  • @centurialinc
    That's a nice setup for the brakes and rotors. Love it!
  • @davidowen888
    All that gravy makes for genius mind 😂 ☮️✌️
  • @memorris2
    That is a genius brake build! Well done!

    Great job Greg , really enjoy your videos
