Frankenbrakes and brake improvement discussion

In case of confusion,I meant the viewer’s who could use something else instead of the custom 3D print’ed clamp.
Yeah, I thought the same thing,wondering why a Biscuit would not be good enough? There has tobe a reason.

Update to code r brakes and galfer 2mm rotors 223 front 203 rear with green pro pads,fresh bleed with motul rf fluid...
.Ok so rode snow summit today bed brakes in did a rebleed before hand...
.
damn brakes will stop a freight rain...amazing

Time for a new brake set, trying to decide between another set of Magura MT-5s or try something new: Hayes Dominions or TRP DH-R EVOs. Anyone have comparison info? Main criteria are power/resistance to brake fade and ease of bleeding (ie, ez to get a good bleed in one try).
Blister has reviews of both. When I talked to David there about them, he said the TRPs have crazy power and nice compatibility with Shimano pads, but the lever doesn't adjust very far in. Basically suggested if you don't wear an XL glove you might have a hard time getting them close enough to the bar.
I just got the Hayes and haven't had a chance to ride them (got food poisoning) but the bleed was really straightforward. Their instructions are very detailed with good little tricks. Messier than SRAM but everything is. Both levers feel identical after the first bleed, which is not something I was ever able to achieve on MT7s or Codes (those always required over filling the rear and/or faffing with bite adjust). The crosshair alignment system is pure genius and works flawlessly. Rollback seems pretty generous even on 2.0mm rotors. The lever feel is incredibly light - I'd describe it as about as light action as you could get short of a hypothetical AXS-style brake.

I agree, but I have big hands. The brakes are killer, but the levers would be an issue for small hands.
I do wear an XL (or XXL in some brands) glove and the TRPs still don't go far enough in for me. It's baffling, you'd need ET length fingers to use the longer end of the adjustment range.
Their power is good, but the Dominions have a little bit of an edge there. The DH-R Evo's lever feel is more linear and not as crazy light in the early part of the stroke as the Dominions, with a less clearly pronounced bite point. That one's probably personal preference but I like the Hayes better on that front too. Both are relatively straightforward to bleed.

Only hesitation on the Hayes has been some reviews stating having a hard time getting a good bleed, despite the extra ports. Sounds like that hasn't been a problem here?
Definately not hard at all. They might be the easiest brakes to bleed due to the extra bleed port on the caliper. I wouldn’t hesitate here. Just get some extra olives and barbs since they are slightly bigger than others.
They respond really well to a slight overbleed like when you pump the brakes once or twice with the caliper off while bleeding.
Plus trp you get a chance to chat with jumping Jerry Vanderpool...lol
My brakes turned out to be total monsters at summit...upgrades were spot on ..LOVE EM...
I will be giving a set of TRP DH when back in stock...Jerry is pretty straight forward been friends with him for a a couple minutes ..he's always been a straight shooter about everything....so it's easy to take his word about bike stuff too...

The question would be if there's enough material in the caliper tabs to tap and thread without compromising their structure.
For sure. I don't think I will use set screws because I want to go smaller than M3 but don't want u use smaller than a 1.5mm Allen key. So it'll look kludgy with socket heads but should be fine.
I really don't think the end result is worth the risk hey
The brake tab is 6.3mm thick on xt 4 pistons and 7.2mm on guides. A M1.6 going through there shouldn't cause an issue.
Think so too, I've seen it done successfully on Magura MT5s, with a bigger set screw as well.
What were you riding before them?
Code RSCs (with and without the Cascade cam set to make them more bite-y), before that MT7s with HC3 levers, and a long while ago XT M785s.
I've Code RSC's on a couple of bikes and no real issues with them. I didn't think much of the MT7's I had briefly on a prior DH bike before I sold it. But interesting to hear you state they're that much more powerful.
Interesting. I've found the MT5s to have a ton of power. However, I'm also using the stock 2 finger levers which have more leverage. When I tried swapping to the HC levers there was a noticeable drop-off.
You'll get used to it.
In preparation to drill and tap calipers I decided to really get out all the runout from my wife's rotors and get the actual caliper bodies perfectly centered.
The lever throw on these guides is silly now like shimano normally is. Getting all 4 pistons to extend equally was a little fiddly.

Just had my first ride on Hope Tech 4 V4 and am also wondering if they have too much power 
. They feel great otherwise and I'll probably get used to the power. I came off of mt5 with2 finger lever and MTX red pads. 200mm rotors. Tech 4s are a significant step up in power for sure.
Lever feel is equally as light to magura, less lever throw, magura with a slightly more defined bite point, you can run levers really close to the bar on the hopes.
They come with 3 different pad compounds which I thought was nice. They come fitted with galfer green (strongest brake power) but also include their red (all around) and purple (ebike). I am going to give green/red up front and green/purple out back after first ride to try and slightly lower power lol.

that 3D printed doohicky that someone posted the other day that released 1 out of the 4 pistons would be very useful. I normally end up using two tyre levers to block 3 of the 4...
For those interested in such tools without a 3-D printer, they are easily made with a piece of hardwood and a saw.
It would be good for exercising them before alignment but I had to get all the pistons to advance evenly after putting the caliper on. Probably going to be less of an issue with brakes other than guides.
SMRT.
I'm normally doing it to either ensure even advancement or I'm wanting to advance a single one to clean the pistons with a piece of string soaked in IPA.
The old Tech 3 V4s used to come with both sintered and organic pads in the box which was a nice touch. Interestingly, in Bikes & Big Ideas podcast discussing the Tech4 redesign, the Hope engineer said the green ones aren't Galfer manufactured, but the other ones are? They do look bloody similar to the green Galfer pro pads though. I might try to find a set of the Hope offerings and compare them to the Galfer greens which are my current favourite pads.
My V4s came with 3, sintered, organic and ebike.
Gunna try a tech 4 front lever.
Dunno, but the backing is colored purple. I figured if it can stop fatties, it can stop me.What's an ebike brake pad?
The organics were worthless.
