Big Dummy - Hydraulic brakes: yes or no?

After spending a few years falling deeply in love with my Big Dummy, I've considering what I think may be the final Major Upgrade: Hydraulic Brakes. 90% of the time I'm on the bike, I have an adult riding on the back with me. With all the weight, the brakes get quite the workout, and I'm having to adjust the rear brake almost monthly due to cable stretch.

Are hydraulic brakes truly the answer to my prayers? If so - which model has worked for you folks?

Thank you!
Henrik

Hydraulic disc brakes would be great on a dummy, the long cable run would no longer be an issue other than finding a hose long enough. Worst case you can buy goodridge brake hose in bulk length, probably a few other brands as well because the hose that comes with the brakes will not be long enough to reach on the rear.

I would strongly recommend staying away from any of the Avid hydro brakes that use their tapperbore system (new codes and elixars) as they seem to need to be bled every few months. Even the guys at SRAM do not hesitate to admit they have issues they can not get worked out completely.

Shimano brakes seem to be consistently good, especially from the Deore level on up and those are the brakes I recommend to nearly everyone.

I had the same question as I want to build a Dummy up when I get home from my deployment. Do you recommend getting hydraulic front and back or just in the back to save money. Which hydraulic brakes would you recommend If I put hydraulic in the back and mechanical in the front, which brakes would work well together and match? When I was looking at brakes online it looks like most of them come with 160 mm disks, do any models come with 180 mm disks? Do any models come without disks so that I can buy the 180 mm disks on their own? As you can tell, I am very ignorant on this subject so any help would be appreciated. Thanks

Just about any model will allow 180mm discs with the right adapter. The caliper doesn't care how big the disc is... just that its on the outside. You can buy caliper/lever sets if you want to. I got Shimano Deore for my MTB and couldn't be happier with the stopping power.

I have had a YUBA for over a year with cable operated Avid BB7's and love them. I haven't used hydraulics on any bikes yet, so can't compare, but the Avids work great, and are low cost. I have a 180 on the back and a 160 on the front. Replacing rear wheel is a little tough with the disc, and sometimes wonder if I should have kept cantilever brakes on the back, with a disc on the front???

Given the way hydraulics work very well no matter how far apart
the Master cylinder and Slave ones are separated why not..
long cable runs increase losses in housing compression and cable stretch.

I have used Maguras Hydraulic Rim Brakes , got a pair of their Julie Discs , but with the Rohloff, big hubshell
160 disc, there was just a little interference.. really would work well on a 180~210 disc, and cassette hub..
and the Hose is sold in longer lengths and very easy to fit..
To raise the Bars, I got longer hose for my HS33, It Was an EZ job..

more expensive ones the hose fittings are not as simple ..

have the Julies FS.. dont have a long tail..

About a year ago, I bought a used BD that already had (cabled) disks on it. I don't know about the difference between running cable or fluid, but, I can tell you that the diff between calipres and disks is night and day. This BD with load stops better than either of my other two bikes "light". Disk brakes, regardless of actuation are worth it.
Another sidebar item about disks, somebody sent me a photo of a guy that put zip ties on his wheels to make "instant snow studs". That bike had a coaster brake set up. You cannot put zip ties on a "rim grabber" of any sort. After busting ass a few times a couple of Superbowls ago, I'm thrilled that I can at least try the zip tie thing the next ice age that we have in the Dallas/FortWorth area.

I've had my BD for years and the Avid bb7 cable disc brakes work just fine. I would not change them over if I was given a set of hydraulics.

I just don't think bicycles are complex enough yet. You should demand a computerized ABS system. That should add enough new ways for things to fail.
