      The heat is a byproduct of the kinetic energy of the car. Multiple calipers spreads that heat over them, so each individual caliper doesn't get as hot as a single one does. The problem with multiple calipers is that they don't give as much rotor access to fresh air for cooling (they reduce effective rotor surface area)

      But, cooling of a brake rotor happens more on inside of it than outside. This is why it is not just a flat plate but two plates in a ribbed sandwich. The internal ribs act as a fan. Also, fading is reduced by not letting a pad create as much friction by letting multiple pads work together. Bigger and almost always better brakes use larger pads for this exact reason.

      By the " heat by the multiple callipers isn't allowing time for the rotor to cool" logic, you should be able to take the stock brakes, using a single calliper, and cut the pads in two to get better braking performance. As others have stated, the energy required to stop the car is constant so there is no additional heat produced. I would argue that the greater mass of the additional brake pads, their backing plates and callipers will help dissipate the heat better. This is why performance brake callipers are finned.
      Oh and wider tires stopping you faster is not always correct. It all has to do with the contact patch, and your wider tire may have a smaller contact patch, and your tire construction will likely be a stiffer sidewall to support the wider carcass, meaning it will be less compliant fore/aft - why drag cars have soft sidewalls to improve grip under acceleration but can't corner for crap.

If not for the trend of oversized wheels, that would probably be common solution today - instead, Audi with C4 S6 [C4 S4 used UFO] switched to ordinary brakes that required 17" wheels...

    • @MadScientist267
      @MadScientist267 Рік тому +2

      Actually it does.
      Say you have 10 psi and 1 sqin of piston. You have a force of 10 pounds on the pad.
      Add another 1 sqin piston, now you're exerting 20 pounds of force.
      Add another piston you have 30 lb force.
      The real numbers will be higher, those were chosen for simple math.
      The volume of fluid that the master can move is the issue. This is why it takes almost all the pedal travel before anything really happens. You can't impose the force on the disc with the pads until there is nothing else left to give, which translates to filling up all the slave cylinders with fluid.
      The sudden and uncontrollable braking at the end is the result of the slaves finally filling up and then squeezing with that full "30 lb" of force, something which normally happens way earlier in normal brake pedal travel, but with much more force on it.
      Pressure wise at the pads, he collectively has the equivalent of *standing* on the brake pedal, but because there's 3x the volume to fill, it takes 3x the pedal travel to reach it, and a lot less effort once it finally gets there.
      The real answer to the current design is to take the rear lines and route them to the front so the master is delivering 2x the volume.
      The braking force will be cut in half for any given pedal pressure but it will happen earlier in the pedal travel.

      @MadScientist267 Рік тому +2

      ​​@@brotang2953And you are right to a point... however that logic only applies if the piston area stays the same but the pad size increases.
      What you have here is simple additive force. The idea is similar to why they add a 2nd piston to a single caliper. The brake force increases without needing more force on the pedal, at the expense of more pedal travel (due to more fluid being required to move the pistons the same distance).

    • @MadScientist267
      @MadScientist267 Рік тому +1

      ​​@@fuzzy1dkYep. It is what allows a hydraulic jack to lift a car with only modest input from an arm. The trade-off is the more weight you need to lift, the bigger the difference in piston size needs to be (master vs slave), but this comes at the cost of needing to pump the master more than with a closer match. With the brakes, this translates to more pedal travel.

      You're on the right track, but not quite.
      The cumulative pressure is far in excess of what a single caliper can provide, even with reduced supply volume.
      There's enough pedal stroke to supply all 6 calipers, barely, but at the end of the pedal stroke and with the ratio designed for 2 calipers.
      They need a higher volume master cylinder with a much shorter brake pedal arm pivot.
      There would be more volume and less mechanical advantage therefore a more easily modulated pedal.

      By adding calipers they changed the fluid volume ratio of the system giving mechanical advantage to the master cylinder. It is easier for the master cylinder to push a smaller volume into a larger volume which is why the pedal became more sensitive. Going to a larger bore cylinder would make the pedal harder giving less feel and response

    Great test guys...from my experience tinkering with brakes, as was said in the video, the master cylinder does not have enough volume to supply fluid to all the brake calipers....a longer master cylinder can help, but will have much longer pedal travel, a bigger diameter master cylinder will push out more fluid giving a greater chance of creating pressure in the brake hydraulic circuits, but will need much more effort from the driver....what can help is altering the stroke of the piston inside the master cylinder, usually the first piston to come out of the master cylinder sends fluid to the front wheels (front /rear split braking system), this piston can be measured for length, then fully compressed in a vise( to compress the spring till the limiter bottoms out), measure again the length, the difference in length will indicate the maximum volume this piston can push out, using a shorter limiter, you can increase the volume output of this piston, however you cannot exceed the maximum length of this piston as it also pushes on the second piston inside the master cylinder, if the second piston is pushed too far inside, it will pass the automatic fill up ports, causing more problems within the brake system- common test to see if a piston has passed the automatic fill up ports is to open the brake bleeders, if fluid does not run freely out the bleeders, the associated piston could be too far into the master cylinder

    I thought that was going to happen. If you further the tests , you would have more success with a larger master cylinder that that matches a fluid volume of the 3 calipers, with a brake line coil to increase the sensitivity parameters. Sounds like a lot of fun 😁.

  • @bertall1ca

    It's better to put more pistons in one caliper. You're increasing the amount of area pressing from behind the pad.
    Also, better brakes fade less. Better tires shorten your braking distance.

      Doing multiple calipers gives the same effect of multiplying pistons. Also increases the fluid volume ratio of the system giving the pedal more feel

    Sounds like a wonderful idea in theory but I'm going to make an educated guess and say that since the calipers cover so much area thus limiting the rotors contact with cooling airflow that this will likely warp the rotors and damage them alot sooner than the stock setup and any gains in stopping power will not be able to offset that fact.

    Cut the centering rings from wheel hubs and drive via pot holes, to check if there is any load carried on the centering feature (and not only the studs/bolts like most people will claim). The goal is to even (maybe) shear the bolts or damage them and cause the wheel to vibrate (therefore the studs are NOT the only things that hold the wheel in place).

    • @dimitar4y
      @dimitar4y Рік тому +1

      Bolt holes are slightly inaccurate, so the centering feature lets you center the wheel to minimize vibrations. The bolts don't do any load bearing. All the load bearing is entirely the friction that the bolts cause by CLAMPING together the wheel to the hub. Loose bolts shear rather quick (1-5 months), and lack of center features will reduce mileage and the steerability/traction of the car. It won't be too dramatic though.

    This was amusing! New things to try on the 3 caliper car:
    1. We all knew the master cylinder wasn't able to handle 6 calipers. Since it's rear calipers are smaller than the fronts, you probably have capacity for 3 front calipers in it. Try this again with a bigger master cylinder that can handle the brake volume needed.
    2. You were already exceeding tire grip on 4 calipers. Tire grip is the real limit of braking. Put MUCH WIDER tires on the front of the car so you have a lot more tire grip. Then try braking with 3 calipers in place.

  • @FireBeam

    Probably getting some deflection between the individual calipers.
    The attachment point was (comparatively) thin metal, so when the brakes are loaded the angles deviate and the brakes "hook" immediately.

    (This is a reply to someone but YT isn't allowing my reply to go through)
    The ABS module only prevents wheel skid, so removing the ABS would improve the stopping distance, since more calipers, more grabbing force, But i surmise you need more brake pedal leverage to overpower the 3 calipers to lock up, Inadequate pedal pressure will not make the Calipers lock up due to more force being exerted against the driver's foot.
    In essence, the caliper pads are pushing away from the Brake Disc, nullifying or making the foot pressure less effective.
    Then again, bigger/Wider tires may improve the braking performance without modifying the stock braking system

    2. You will need a bigger brake fluid reservoir.
    3. Regardless of how much braking force is applied to the wheels the limiting factor is going to be the traction between the rubber and the road.

    Original disk brakes have a clutch plate sort of brake pad that covers the entire rotor. Current disk brakes used to be called “spot brakes” because they only clamped a single spot on the rotor. So this is a step backwards in brake development.
