That would actually be really interesting to test the brakes both ways.. Stock and then with a control pad and rotor set up. Then compare the results.. Especially when you look at some cheaper Shimano brakes.. A pad and rotor swap typically makes a huge difference there.. Some say they are even better than some of the higher end brakes..

another thing I think would be cool to see is pick one caliper, then test as many different pad compounds as are available. would need to be a common brake (probably shimano or sram) that has the most aftermarket / 3rd party pad compounds.

You could use something like a Code brake and then use pads and rotors from aftermarket companies... I think we just gave Vital some content ideas...

I'm most interested in pad life tests. 

 

All the top brakes are fantastic in my eyes, they all behave slightly differently but all provide more than enough power to lock a wheel, anything more than that is unnecessary.

It's about lever feel and heat dissipation for me, lever feel is subjective. But I'd love to see heat dissipation tests. 

Some brakes are absolutely cooked after a DH run, and power at the first corner is great, but by the last it's gone.

Weird kona rant, I had a medium process 29 153 and had no issues with bottles fitting. Wife has a small 27.5 process 153 and can fit a small bottle no problem.

Mine's the 27.5 medium, but it's the same issue on the 29er from what I saw in store.

I can barely get a 450ml Fidlock in.

Hmm, pad life test would be interesting. Difficult to correlate directly to real world usage. Maybe one test run runs with a fixed pressure applied to the brake lever with the hub/rotor in a fixture spun at a constant rpm, then measure how long for the pad thickness to reduce by 50%? 

Another idea would be to have an "averaged" pressure/time profile created from brake telemetry data (from real world bike park runs), see how many cycles (runs) it would take to reduce the thickness by 50%?

My quick thoughts on two of the brakes tested by Enduro. For context, I am lucky enough to own and ride a fleet of 5 bikes consistently; from DH to XC

Formula Cura 4: been running these since 2019 on my Trail and XC bikes. Getting a good bleed is paramount to good performance. Sintered pads definitely add extra bite, which I prefer. They require a bleed every couple months to avoid a soft lever feel. Lever bushings get sloppy after a few hundred miles and require replacement.  Fully rebuildable if you are mechanically inclined (which I am and have done at least twice on mine)


 

Trickstuff Diretesimas: not the Maximas but mechanically the same. Run them on my Enduro and DH bikes. Amazing, consistent performance with the power+ pads. Very linear lever throw and rarely require a bleed. Lever hardware is like new after nearly a 1000+ miles. My personal favorite.

pretty sure there must be a thread regarding brakes… back to rumors please!

Magura MT8 brakes on sale for a while in German webshops. Maybe a new version comes? Smile

(No major change to MT8 brakes since late 2014/early 2015 except for the flat mount caliper, which was introduced a few years later.)

let's hope they update the whole thing, calipers are perfect, cnc or alloy masters, rebuild kits and resolve that poor spring technology on the lever blades is what they need to focus

New session in the works. Screen grabs from team video.

Looks like some kind of stiffness around seat tube/BB area. Maybe frame enclosure around shock for lateral stiffness? Chainstay, seatstay look the same.

Calling it now, its going to be an Intense clone (mid  high pivot, faux-6 bar suspension) except for the ABP instead of a true Horst link.

I'd say that's a very good guess.

Some brands really do the frame wrapping thing better than others.

Eagle derailleur was feeling left out - so I made a thing - replaces the washer on a standard UDH dropout with a "Brace" that links the rear derailleur for strength and stiffness.

Brace Front 0Brace Back

I have a small number of these available if anyone is interested: https://solutionfactory.bigcartel.com/.
