Thanks for that! Does it drop to 8mm soon after the start of the stroke and roughly stay there? The spreadsheet will eventually need some corrections for both lever arms' angle change in relation to the piston rod (and finger) as levers move through their travel but maybe someone else can nerd out on that. We'll need to add a main-pivot-to-bar-center distance column. In any case, very interesting that M820 peak force is pretty well identical to the DRT (with your measurements at least). If you can double check M820 slave piston measurements that'd be great too, 15/17mm is written currently.
Yeah but tiny differences in that stuff can impact rollback - piston diameter differences you can't see with your eyes, and differences in even rubber durometer of the seal (as well as its exact CS etc). The shape of the gland has the biggest impact, but the seal and piston matter too.
Yes.
Aren't those pretty recent warranty replacements?
They are a year old. I was trying it now most of yesterday evening.
Sounds like another round of warranty-bingo is in your future.
I'd pass, if I were you. Me and my regular riding buddy ran them. Me on Hope V4s, him on the Code RSCs. They developed a strange pulsing sensation after a while. We tried different OEM pads and the race matrix back to back. The Uberbike pads seemed to be the problem.
Preheat oven to 400 F.
Go get them really hot and report back.
Is that with the lever problem in hot ambient temps? I thought they fixed that?
Well, they're now in limbo, so fingers crossed. If I get a new set, I'm either going to try out those Curas, or I'm going to try and take advantage of a Magura hookup I might have.
I'd probably hold out for the Cura4, Formula levers in particular are built much nicer than Magura, unless of course you really need the 11 pads.
In a word, yes. The problem with two piston designs is that you always have an "overturning" force on the brake pad from friction, so you will never get even pad force and wear. With a properly designed four piston setup, you can get the trailing/larger piston applying a greater force to counteract the frictional overturning and get a much more even pad wear and force.
What pads did you put in?
i put in 8.R. I believe the mt7 comes with 8.p (performance. The mt5s come with 9.p, and available is 9.c. Most people say the mt7 with 8.p have adequate bite and stopping power, so I have a hard time believing the 9.p and 8.p are the same pad compound, because that means that simply splitting the pads in two gives huge increases in bite. I think I got mine off merlin for like $25 an end.
Your're gonna die.
