[@KaminKevCrew]

As someone else has already highlighted, hydraulics kind of change the way this work. That’s because in the hydraulic system, you have a certain amount of pressure. The thing is that while you would have the same amount of pressure in the system (PSI), you have more area across more pistons. Because it’s a hydraulic system, the more surface area you have (by adding more pistons), the more pressure you have acting on the brake pad. If you have 100 PSI of pressure in the hydraulic system, and you have 1 square inch of piston surface area and two pistons, you would have 200 pounds of force acting on the brake pads/brake rotor. If you have the same amount of pressure, but 6 pistons each of the same side, you will have 600 pounds of force instead, because you have a larger surface area that the pressure can act on. The thing that you end up losing is travel. The 6 piston caliper will only be able to move the piston 1/3 the distance of the 2 piston caliper. That’s why they felt so much stronger - they are literally applying more force because they have more area that the hydraulic pressure can act on. They’re not going to be 3 times as strong as the two piston calipers, since the other pistons are smaller, but that’s why they were stronger.

[@jamescaldwell5]

When taking advanced physics in High School and learning about friction calculations, I asked my teacher: "How come performance oriented cars have wider tires?" His response was quite snarky and basically said "so they have better grip" He did not grasp that the equation he was teaching us states that spreading out the contact surface would equally reduce the amount of force applied to the surface per area, and thus cancel out the desired result. However, when it comes to friction, real world testing is far superior to calculations and the same force applied to the larger surface area usually creates more friction.

[@Adurianman]

Nope, if you do real world testing it would proof that friction is exactly the same no matter the contact area when same compound and force is used. Why we use bigger contact area is because the material are able to resist the mechanical loading and not break off, friction generated is the same, but traction differs

[@Seppes94]

Also heat. Narrow tyres with the same compound would melt if used on a racecar and larger brakepads disperse heat better.

[@jamescaldwell5]

@@Adurianman With real world testing, how do you measure the difference between friction and traction? How do you explain his test results?

[@Adurianman]

@@jamescaldwell5 there are many videos on KZbin that demonstrates that friction is wholly dependent on just the force, and coefficient of friction. You can put a similar mass out on same material with different sizes and you measure the force needed to move the material with weight on it. Unless things breaks off, the force required to move will be practically the same, showing that friction is not influenced by contact patch kzbin.info/www/bejne/eaqrZquFmNiLrtU

[@proffesorDub]

Great video Luke! Just as a potential ‘other scenario’ that people would buy these for. I myself am a juin tech owner, mainly because in 2022 I went from rim brakes to disc, but only wanted to upgrade the frame and didn’t want to buy a whole new groupset (I have a sram red 12 speed axs grupo). So initially I went with the 1 piston caliper, which whilst it worked it felt a little lacklustre. I ended up buying two of the 6 piston in the fetching purple (weighing it up against he Paul klampers which are slightly cheaper) In my opinion the brake performance offered by the GT 6 is exceptional, and more than what I need for my road bike. What it did mean is that for 400 pounds, I avoided spending over 5x that on a new sram red grupo. And are still cheaper than just buying a sram red pair of Brifters and callipers A very niche use case I know, but they’ve given me the ability to use a disc brake frame without too many additional costs. Keep up the great work!

[@piotrcichy7316]

The Juin Gtf-6 would be great for a disc brake tandem bike!!

[@emmabird9745]

Great Luke, I like your methodology. You are quite right that friction is proportional to normal load (pressure as you called it) so for the same size rotor, with the same pad material, then you should gat the same braking for the same hand pressure regardless of pistons and pad area. However it friction ceoficient that can change. Pads can out gas during use due to the heat reducing ceof. leading in the extreme to fade. That is well understood. However there is another effect which can make a difference and that is shear stress in the pad marerial. Less area leads to higher stress which makes the fibres in the material lean over more and so reduce coef. Thats on a tiny scale of course but can in some manner explain some of the difference. I would recon that the hy-rds will compensate for pad wear better (because of the resevoir) so performance at max wear will be much the same as new. Great testing Luke, keep it up. Small point, off topic, is that cable operated hydraulic calipers are like the old magura (I think that was the brand) with the remote hydraulic block on the stem but more integrated.

[@ranitbose9609]

This is the only explanation that seems to make sense. Since otherwise there isn't any reason for the normal force or the coefficient of friction to change as Luke had stated

[@Finnspin_unicycles]

@@ranitbose9609 Typically 4 piston brakes have more hydraulic leverage (ratio of caliper piston area to master cylinder piston area), so the normal force is changed when compared to 2 piston models. You could of course increase the hydraulic leverage on 2 piston brakes too, but that runs into issues at some point (e.g. short and wide pistons will have a tendency to get stuck and spoke clearance is limited, master cylinder pistons can only become so small while still being strong enough), so at some point it becomes easier to add more pistons.

[@landixus]

I never know that there are hydraulic brake heads on the market, i feeling like a n00b after 20 years of riding. I need to investigate this cool STUFF! Thank YOU for pointing me on it!

[@Sierramike524]

Fairly sure multi pistons are more powerful because the total piston surface area is larger, so the hydraulic leverage is greater. The same can be achieved if they increase the size of the single piston, but the packaging would be kinda ass.

[@szurketaltos2693]

As I understand it, with a typical full hydraulic system you aren't increasing the piston surface area much going from 2 to 4. What you do get is (1) more brake pad surface area and (2) more even pressure on the pad. Ultimately you are limited by the size of the master cylinder, especially for road brifters. However, with a hybrid brake it is possible to have a substantially larger master cylinder and therefore more piston surface area.

[@brackishcycles]

@Sierramike524 is correct

[@szurketaltos2693]

That is, if you increase the piston area, force will increase proportionally but the distance that the pistons travel will also decrease proportionally. 10% will probably not cause a huge loss of clearance, but if the pistons were 100% bigger (2->4 pistons of same size), that's definitely liable to require very very true rotors. If you want to keep the same clearance, you would lose pressure on the brake pads.

[@ryanmcivor1532]

Those centerline rotors? Aren't they on backwards?.... NM just saw it addressed in the bonus clip. Love that lead in BTW👍

[@mattspencer3294]

Funny he says it doesn’t make a difference, I’ve once put a centerline on backwards and under heavy braking you most definitely can tell, I was chasing a weird vibration forever, then flipped the rotor to the right way and it was totally fixed. The spokes are designed so the rotor is stiffer in one way and helps a lot with vibrations

[@stuka78]

For an electric bike, where you have lots of cables running into the frame, in a crammed space, having mechanical cables and hydraulic calipers would make assembly and maintenance much faster and easier.

[@motionstudio77]

Another great review Luke, is good to know the differences between these high ends disc brakes.

[@JoeMooney]

Force is Pressure/Area so, at the same pressure, you would expect more force with the larger contact area.

[@EthanBlock]

The frictional force is equal to the coefficient of friction and the normal force of caliper on the rotor. Having a larger brake pad will increase that coefficient of friction. The other reason a 6 piston brake may have more friction is that there may be more mechanical advantage (i.e. the force from the brake lever isn't the force on the rotor). I do not think heat disapation has much to do with the performance difference if at all.

[@christopherharmon9336]

Great video! It's good to see options in the mechanical-disc world. Personally, I like the simplicity of mechanical brakes. An Achilles heel of mechanical disc system is the housing. Compressionless housing will dramatically increase the power and feel of even cheap mechanicals. I threw compressionless housing on my 2019 Radwagon, which has inexpensive Tektro mechanical discs. I can now easily lock up the rear wheel, with much more control and power compared to the old housing. I strongly suspect GOOD mechanical discs and GOOD housing or compressionless housing will significantly decrease the gap in performance between a mechanical and hydraulic system. I also suspect that there is overlap in performance-would it be "better" to have JuinTech, Growtac, TRP or Paul Klamper mechanicals compared to some entry-level hydraulic brakes? The answer is probably yes. These hybrid-style brakes are an interesting option.

[@tomalbert3299]

The former head of Trickstuff once told me that the larger a piston is or if you have two in a row instead of one the brake pads won't twist as much. The result is a more equally distributed force on the brake pads. Think back when we had V-brakes. Maybe you remember how a worn pair of pads looked like - the front of the pad still had material left while the rear was completely gone. Now that I think about it the brake pads of my old two piston (having a small diameter) brake the same happens there as well.

[@jamesheedrpg_god-boss3676]

yeah this is true about more brake pistons, its really no different than car brakes or big brake kits. on your stock standard car you have one piston on each side of the rotor pushing the pad into the rotor, this is nice and works well but your not utilizing the pad well enough and can often get inconsistencies in brake performance or brake fade. inn comes the big brake kit, a big brake kit tries to solve two problems, heat and consistency, the increased amount of pistons in the calipers allows you to run bigger pads distributing the pressure more evenly over it, this will make them more efficient not building up the same concentrated heat that makes brakes fade, this should give you more consistent braking and since you distribute the pressure over a larger surface and there is more material for the heat to soak into, in addition to this most big brake kits have larger ventilated and drilled or slotted rotors that will aid in cooling as well. the main goal for bigger brake calipers is not stopping distance but consistent performance when your brakes are hot.

Also folding bikes since you can bend cables with no worries but hydraulic hoses might get crimped over time.

[@BlairAir]

Actually, I know JuinTech for their M1 model, I think it's marketed at Ebike customers. The big draw of these is the thought of mounting them and being done in 10-15 minutes vs. pulling hydraulic line through a bike frame, pulling grips off handlebars and setting up a traditional brake system. It's a lot of brake force for the least, the absolute LEAST amount of effort. The BARE MINIMUM of doing a damn thing. My thought? If you can buy s full set of levers, calipers, lines and supporting hardware for the price of a caliper (a well made, with top materials and precision manufacturing) then it become a question similar to what Sean Connery asked Kevin Costner in The Untouchables - What. Are You Willing. To Do.

[@philippecardin1109]

I think you could achieve the same result with just longer brake pads instead of more pistons. More friction equals more braking power, it's that simple.

[@avalsirithanawat1772]

Opinion: The reason a car's brakes make up a much higher mass ratio to the vehicle compared to the bike is the speed difference. Say a bike might have to stop from 30mph vs 60mph for a car. If a bike regularly travels the same speed as a car i.e. 60mph, it would have 4x the kinetic energy since KE is proportional to velocity^2. So if you assume a car travels around 3x the speed of a bike, it would need ~9x the rotor/vehicle mass ratio, which makes sense. :)

I recently upgraded my mt400 series brake from 160 to 180mm, and i upgraded from bso1? to to bs05 shimano pads. the bs05 claims 50% longer lasting but I also have a hunch the bite is less cause my disc upgrade didn't rly make it feel stronger..or just not what I had hoped. I think this happened: because new pads are more slippy, that 10% of extra theoretical power might be more like 5% now.

[@harrison00xXx]

But in general it should increase long time reliablity a lot by doing so. I also upgraded from already decent/good stock Nutt hydraulic brakes (2 piston) to 4 piston and bigger disc but the hardest possible pads. From about 1500-2000 km per set of pads im now at over 3000 km and the better brake system still goes strong as well i have noticeable more braking power if needed. My stock Nutt brakes were ok... NICE to control under regular conditions, but HORRIBLE for emergency braking since a ton of force was needed.

Hey Luke! The comparison with a car with respect to the percentage of mass of the discs (2% of mass for car vs. 0.2% for bike) does not really work, because the energy to be dissipated (to come to a complete stop) is 0.5*m*v^2: the velocity is squared, so for double velocity, the energy is quadruple. A car moves much faster than a bike, and that's why the proportion of disc mass is way higher. Your argument would work if cars were heavier, but moving at the same speeds as bikes.

(other advantages for hydraulics: no degradation due to dirt on a cable and friction, self regulation of piston position as pads are used up, more even pressure on the pad, no need to use precise bearing for the caming mechanism that pushes the pad {BB7 stands for ball bearing BTW})

Let me ask you what are the distances in milimeters (they look the same) between the caliper mount points also the distance between the flat mount points on the flat mount brackets that come with them? I need to evaluate before I buy if I can put the on a Salsa Journeyer with Microshift SWORD group set which beggers another question are they short pull?

Just get moped brakes at this point. Cheaper, just need to mcguiver it a bit or find adapters like I did

[@TraceVelo]

This is a super interesting idea, do you have a link to the calipers you used?
