i have thought about doing this to my et410 with the same chaincase. the master cylinder and brake light switch can come from any sled. the caliper from the front of a motorcycle will probably work the best as the rotors are similar thickness. i would go with a single piston caliper in the 9-10 oclock position with the piston over the exhaust for clearance. then i would fabricate a bracket to mount the caliper to the existing brake system bracket location.
i helped a buddy do this on an old skidoo he was setting up for ice drags. we used an xt 350 caliper and pads on the stock rotor with a master and like from a formula plus he had hanging around for parts. i would have to go through my stuff and see if that caliper would have the bleeder screw in the right position for that sled.

The problem with this brake modification is that the brake disc is mounted on the outside of the chaincase,
and there is lack of space sideways.

that is why i suggested a bike caliper with the piston out over the exhaust in around the 10:00 position on the rotor.

they have more clearance than most sled calipers i have seen in how they are made. it looks like you need one from the right front on a banshee from the pics i have seen. once you have it mocked in place, you then fabricate a peice of steel that connects on its mounting area to the origional mount point for the cable brake. run line, bleed and hook up brake switch on bars.

Here in Sweden it's impossible to get a Banshee caliper since it not sells here.
I have looked at a Polaris RMK "PRO" caliper because of its small compact size.
Your thoughts on this ?

yes that caliper would work. it looks thin enough and bleeder is in right spot.
Mounting bracket... ?
I now have got a Polaris RMK "PRO" hydaulic brake caliper and have started to look how to mount it on the Venture gearcase.
I will have to shift the brake disc around to make it accept the brake caliper.
It is very limited with space and there is actually only one position where the brake caliper can be mounted.
Please share your ideas how to make a mounting bracket.

I have done conversions on Vmax 4 and used SX-R or SRX brake parts and line and handlebar controls. Trick is making a parking brake that works.

Did this for TSS Vmax 92-96. Same concept may work on other sleds.

I have some calipers and controls from some SX and SRX. You would have to make your own mount plate. I might even have a few disks if you wanted to concert to a bigger disk.
Thanx for your offer, but I'm in Sweden.Parking brake is no problem, Im already have got the brake master cylinder from an Ski-Doo XP and the brake caliper from an Polaris RMK "PRO".
Problem for me is the very limited space since the sled have Reverse gearbox.

I know this thread is old, but I'm doing the exact same mod. Putting juice brakes on a 90s Venture reverse chain case. I've seen plenty on regular Phazers, but nothing on a Venture.
I've read many mod posts like this, but nearly every single one never list COMPLETE information. Parts used, what worked, what didn't work, gave up, etc. Thank you for sharing what you did, but please don't leave us hanging! That's just rude bro! I'm guilty of this as well. Nobody is perfect. But damn... throw us a bone!
A single completed picture can be worth a thousand words and hours and hours of head scratching. It can also save a lot of money from buying parts that won't work. I don't know how many hours I've spent trying to dig up information like the old Bender kit that apparently used to be available. That parts list would sure be nice!
Ok... gripe complete... now on to my mod:
I have the Venture reverse boxes on 2 of my Phazer II's, (well.. one is complete and I'm in the process on the second).
While gathering parts for my second conversion, I was considering a hydraulic brake conversion while I'm in there, because... well.. why not? There's no problems with my brake, I just want to upgrade when possible and because my hands are getting weaker as I age (arthritis), so any help on that brake would be nice. I've never cared for the cable brake.
So.. what parts were successfully used on the Venture reverse box? Please post pictures! Lots and lots of pictures!
I was looking into a larger rotor but as one already pointed out: there are space constraints on the Venture. The disc kinda sits back into the chain case so there's really no room for a 'wrap-around' type caliper. This might be solved by flipping the rotor around, but a larger disc might hit the exhaust. I don't have a larger one to test that. I might pick one up as they are cheap on Fleabay. I've found a vented one like a car's disc and another that has some fins on it. Problem is - they might be too wide as well as their diameter.
Far as the caliper - I'm going to try to mod a single piston style that sorta replaces the original in the exact same spot and uses the same brake pad. Getting it bolted is the hard part (obviously), but I have my own machining and welding equipment, so we'll see what I can cobble together.
I was even considering machining my own custom caliper. Again... why not. That's the beauty of being retired with too much time on my hands! And I'm a machinist, so I'm always looking for stuff to do or tweak.
Until I seen someone else's photo, I didn't even consider flipping the disc over to use a regular non-modded caliper so I'm looking into that as well. Parking brake is a whole different animal, but do you really even need one? I only use it when I have to lock the jackshaft to work on the clutch or something. Throwing it in reverse is almost the same as a parking brake.
Again, I know this post is ancient so hopefully someone with information can still help! I'm definitely documenting my mod very carefully this time and will post everything once it's done.
