    Radial mount calipers are super common in superbikes. It is way stiffer than axial mounting calipers and it eliminates shear force on fasteners.
    From Rider Magazine: "That’s a seemingly trivial difference, but radial mounting yields some important benefits. For starters, radial-mount calipers provide better caliper-to-disc alignment since the caliper body is centered over the disc using locating dowels rather than sliding pins as on an axial setup. Radial calipers are also more rigid since the caliper is secured at both ends rather than at just one end as is common on axial calipers. That improved alignment and rigidity can provide better bite, more stopping power and improved feel under aggressive braking, which is especially important stuff to roadracers"

    • @waynelevett3632
      @waynelevett3632 2 года назад

      Yes. I could see it would be more rigid than a usual caliper side mount that has a minute flex. I think it's a great idea from superbikes. Thank you

    • @GROND15
      @GROND15 2 года назад +12

      It also reduces the likelihood of the pads dragging on the rotors. So it is a more efficient system. And the "feel" is much improved.

    • @spankeyfish
      @spankeyfish 2 года назад +2

      The caliper body is only mounted on slide pins when it's a sliding caliper, usually a single piston one. Opposed piston calipers are rigidly mounted but perhaps not as rigidly as radial mount ones.

    Hi Sandy and Cory! Love your work. I rebuild salvage Teslas in Ukraine. Own MX p90d and MS P100D. A couple things I request you to PLEASE examine closely on the Plaid:
    1. Spline on the drive axles where they meet the hub in each wheel. Interested if they made them beefier on the Plaid, on the MS and MX performance, they are so small, with small teeth, I'm amazed they can handle the torque, especially considering vehicle weight.
    2. Pyro fuse on battery - interested to know how it's upgraded over Ludicrous fuse, and if possible, please find out max amps the pack is putting out.
    3. And of course, battery cells! Configuration, connection, BMS, etc. Realky want to see how they achieve 25%+ more amps from the pack while still using 18650s.
    4. Maybe examine suspension components versus the standard MS (upper / lower control arms, etc.) As you probably know, there is a history of problems with them breaking, especially on the porky Model X. (I lovingly refer to mine as a 'hippopotamus on stilettos.')
    Thanks, and keep up the good work! PS - grew up in Metro Detroit )
    Edit: keep remembering more things!
    5. Look at rear drive unit, how inverter is integrated into that assembly. As you know, in old Performance drive units, the inverter was on one side and motor on the other. Also, compare rear and front drive units to the M3 performance motor- I heard a rumor that the Plaid is basically using two M3 performance drive units in back, one in front.

    • @andrasbiro3007
      @andrasbiro3007 2 года назад +7

      I think they talked about the inverter. It's different because of the width of the two motors.
      As for the Model 3 motors, it seems very unlikely, as one of the main features of the Plaid is the special carbon-wrapped motor. My guess is that it comes from SpaceX, they are using a similar technique to contain extremely high pressure gases. They did a ton of R&D on that after a failure costing them a rocket and payload.

    This type of caliper are very common in high performance cars, and standard om most motorcycles and is called a radial mount caliper. The point is to avoid twisting of caliper and hub during braking due to the te moment induced by the offset mounts of the bolts. The point of the "virtual ball" suspension is to avoid torque steering by getting a variable scrub radius wich is propotional to the wheel toe in/ toe out on each side of the car. The system was first introdused in Audi A4 almost 30 years ago. The downside of the system is that the steering often feels numb with bad feedback, wich is why eurpean fwd GTI cars usually use a different system.

    That kind of caliper mounting arrangement is common on high performance cars with big brakes. Taycan has it, Lotuses, McLarens and Ferraris have it. One of the reasons is that it’s lighter (no ‘ear’ on the caliper). Another reason is ease of caliper removal (no need to get around the back of the knuckle). Another reason is to reduce overall track width (length of thread in the knuckle would push the disc outboard and make the car wider).

    thanks for reviewing the harness. I would appreciate a comparison of connector types used by Tesla and other OEMs. After 9 years of harness design, I'm often astonished at how complicated some of them are becoming. Not mentioning having HV connectors inside the pack when you could get away with a bus bar, braid, or a welded cable to join point A and B. You might say assembly speed, but often components cost is much higher than labor cost with a more primitive solution. Tesla made a giant leap from the first Model S to Plaid.

    That's a radially mounted brake caliper. Very common on high end braking systems, especially aftermarket. Also common in air disc brakes to a small extent.

  • @MEKKER1B2
    @MEKKER1B2 2 года назад +1

    Radially mounted calipers initially comes from Motogp. This provide better caliper-to-disc alignment since the caliper body is centered over the disc using locating dowels rather than sliding pins as on an axial setup. Radial calipers are also more rigid since the caliper is secured at both ends rather than at just one end as is common on axial calipers. That improved alignment and rigidity can provide better bite, more stopping power and improved feel under aggressive braking, which is especially important stuff to roadracers.

Do you run a bunch of air fryers in the break room over lunch? Do you throw the hot end into a full horse trough? And how do you know everything is dead and thus safe?

    Sandy I am an industrial mechanic and in my field the way we have reduced cost and ease the install is to use remote input/output modules. This way the computer communicates to the modules through a data cable to send and receive information. So now we only have to pull 3 wires instead of the 40 to 100 wires that we used to. Are auto makers incorporating this kind of technology, and who if any are?

    I'd be interested in the potential evolution of the battery compartment. Tesla originally announced a 500+ mile variant of the Model S and then retracted it. What is inherent in this design that would allow for future battery volume or shape changes? The easy answer is the 4680 cells in the exact same module would allow for the enhanced range, but perhaps there is more to it.

    • @markplott4820
      @markplott4820 2 года назад +2

      Key things are, CELL constraint, 4680 not Ramped.
      1865 Tesla cell , superior to everyone else.
      and adequate for mod s performance.
      besides, Tesla has 40,000 supercharger in 2022.
      and EA only 500.
      however, the 2022 mod s pack , has to be completely redesigned for 4680 as they are taller. and Berlin is mounting it's Front seats 💺 to the 2170 structural pack.

      @@markplott4820 Hence my question. 4680 delay in development and QA has likely occurred, as inferred from the delay times on CT, Semi and the Plaid Plus retraction. Sure, it's possible they decided to abandon their prior roadmap on these models, but I think unforeseen delays are more likely. Austin Model Y might well be the first 4680 structural pack to reach consumers. CT backlog is now enormous. They need to get that product in production with 4680s in order to meet their pricing goals. If CT is released with 2170 batteries, the planned for margin will be compromised. I am dubious of any new products coming to market with the old 1865. We are in a transition period. The Plaid Plus and the 3 motor CT both targeted 500+ mile range. Seems likely they were doing common development on the battery. At any rate, as a retired engineer I enjoy Sandy and Cory going deep on this.
