Frankenbrakes and brake improvement discussion

Yes. The geographic area you just described can all be characterized as what I like to call "The Poo Zone".
Just changed the Tektro calipers out for some Sram Db8 calipers I got cheap. So, "Zrams" now.
Extremely happy with the feel of these now. Nice and firm bite point. Heaps of power.
A couple of mates have tried them (their brakes are, Hope Tech 4/V4, Dominions and DHR EVO). They have also been impressed, which is a nice change from the brakes I have run in the past
My Vitus came with DB8's. I planned on swapping them out right away but made one quick trip to the bike park with them and was very impressed.
Hmm, those DB8 calipers look appealing for hacking some SRAManos together. If anyone has a lead on cheap calipers, please chime in.
I was super lucky with this. I was browsing for other stuff and came across them for $60ea (AUD).
Must've got the last couple too as they don't have anymore stock.
You can find them for around $50 USD. It just surprises me that you can find Maven calipers for only $30 more. It really has me wanting to play with a set.
Got a bit frustrated with Hope yesterday.
I got my girfriend a new secondhand bike with Hope Tech 4 / V4 brakes, super pretty, hardly used.
But when you feather the front brake, you can slowly pull them to the bar. Clearly a master cylinder issue. Hope says: warranty issue, return them to the store... Well they have been standing in some germans attic for 2 years, so that's not possible.
So i figure i take the lever apart to see what's going on, hope brakes are rebuildable after all.
Turns out they use a security torx to keep the piston in the lever, argh, have to buy more special tools now.
Should have stuck with shiguras...

If it happens while riding when first delivering power, it's air in the caliper trapped behind one of the pistons. If you can pump up the brake and hold pressure, its not the MC.
I have a need to bastardize some caliper to a Hope Tech 4 lever since their E4 caliper doesn't fit this frame. Who makes a DOT fluid compatible caliper that uses 4x 16mm pistons? That original spreadsheet appears to be way out of date.
First pump is solid, but when you lower the force to a light feather, it starts to move towards the bar.
I'll open it up today to see what's going on. I've got the security torx bits in the mailbox.
So that matter cylinder seal is already toast... Guess it's difficult to deburr a timing port deep inside a 9.5mm bore.
Do any of you have or heard of experiences on Braking Incas 2.0 brakes? They do know the motorcycle side so I guess there's a theoretical possibility to make a decent product?
Paul Aston wasn't much impressed with them:
Braking INCAS 2.0 Brakes Review — AstonMTB Reviews
The INCAS 2.0 brakes are made in Italy by Braking. So they are Braking brakes…confusing I know.
www.astonmtb.bike
The similarities with BCA brakes are...nearly identical. The topic mentioned an interesting thing: "To use the Braking 3mm Wave rotor you need to add a spacer which has cute little cooling fins. You need to split the caliper and then re-bleed the whole system."Paul Aston wasn't much impressed with them:

So can I machine a spacer to my Saint brakes and run a 3mm 220m disc? I'll have to split one extra caliper that has a broken piston.
The small SRAM bleeding edge caliper covers, anyone know where to get them?
Like the dust covers, on the calipers?
Yeah, doesn't seem to be any/many sources and not wanting to pay $10 for a 10c part.

Would a hot glue gun work for that? Fill the hole and then rip out the plug when needed?
Or get @Westy or your local library to 3d print one?

Bleeding Edge Cap for SRAM | Code, Guide, G2, Level, Red, Rival, Force
These bleeding edge port caps/covers are made for SRAM brake models, Code, Guide, & G2. This little cover is surprising hard to find so we made some for our friends to cover their open bleed port. 4 caps for $5

I would print one out by applying a blob of RTV to them.Or get @Westy or your local library to 3d print one?

Interesting concept. Nothing for the brake rub sensitive folks though I guess.
Anyone run sunstar Incas and 3mm rotors?

Downamics Racing Performance on Instagram: "The @setontuning pistons are a game changer in terms of improving the lever feel. The @hayesbrakes already had the lightest lever action available out of the box, but these special pistons make the lever lighter to pull due to an improved surface finish, reducing the friction. I need to get them somewhere with proper terrain in order to get some decent temperatures in there but just looking at the difference in design and materials used compared to the standard pistons, I would expect to see improvements here also. . . . . #brakes #pistons #friction #hayes #dominion #hydraulics #marginalgains"

Ordered the 4 and 4.5mm of these, will update if they work.

Ok, bear with me, kids. At 3:00 in the morning, (total insomnia) I had an idea for a product that must exist in some form already. Basically, I am looking for a very low power ‘sump’ pump. The idea is to have the intake inserted into a container of brake fluid, and the output go through a hose the same diameter of whatever your brake requires to connect to the bleed port or nipple. I would also like to make a locking ‘quick connect’ hose fitting for the Shimano bleed nipple.
This is very simple technology, I would imagine, and could be quite small and rechargeable.
It wouldn’t be revolutionary, but not ever having to faff with at least one less syringe could really, really simplify the bleed process.
Does anyone know how they add fluid to brake sets during initial setup at the manufacturers?
It has to be somewhat similar.
I definitely want to experiment with this over the winter.

labor in ASPAC is cheap?
I think it would reduce waste, and speed up efficiency, and possibly prevent aeration?
Maybe something like this:
Maybe something like this:
Won't that contaminate a lot more fluid than needed with a normal bleed?
What problem are you trying to solve with it?
The solution still seems to be @Nick 's Radic brakes
Honestly, everyone that tries them, buys them. I hope this guy makes $$$ and can ramp up production and stock.
What problems do you people have with bleeding brakes? Always been a pretty simple process for me and I generally only do lever bleeds. The key is doing the bleeding with the pistons extended. Pushing them out prior to pad insertion will help push air back up into the lever/syringe.
It’s for maintaining a fleet of rentals. If the oil stays clean (it’s one way, in general) , the system stays closed, and will be much less susceptible to contamination. My idea is to have a sealed cap that runs one hose to the bottom of the Shimano jug, and the other end with a secure quick connect of some type.
Think doing 10 full bleeds as opposed to one or two.
Lever bleeds are obviously simple, this is more of production solution.
I already have the pump, hoses, and power sorted, now to figure out the secure quick connect.
It’s not addressing any ‘problem’, it’s to speed up and improve the entire process. I’m sure that thinking is in your wheelhouse, Westy.
I probably do 50 full bleeds a season.

I had something like that as part of a Hope bleed kit for my V2's years ago, pressurized by bike pump IIRC. It was too much faff and I never bothered using it.
