Cable Pull Hydraulic With One Direction Caliper?

[kevinmccune]

I was toying with the idea of replacing the calipers on my project with cable pull Hydraulic, there seems to be a handed issue, the build is going to have one caliper right and one left, the parts suppliers say for one direction only, why? can you just flip the rotor?

Does the frame have hydraulic brake mounts brazed on?
That said best cable pull hydraulics aren't significantly better than best-grade calipers with upgraded KoolStop eBike pads at the speeds I ride. 15-20MPH.

Cable-pull hydraulics lack one of the major benefits of hydros: No cable stretching or adjustment during the life of the pads. On mine you just install the pads and forget about them as they self-center.

Its seductive to retrofit cable-pull as you don't have to mess with changing calipers or removing the existing cables and replacing/reattaching hoses. I would resist this temptation. I did it for my daughter and son-in-law with some VERY nice Juin-Techs and ended up with a do-over with Maguras about a year later.

As to answering your right/left question, there should be no difference except at the levers. And... right/left? Is this a trike? the levers may not be ambidextrous but if you are changing to cable-pull I would think you aren't changing the levers.

actually if you dont replace the crappy cables and housing with compressionless stuff you will still not have a great setup.

I found this out the hard way on my Envoy.

I had upgraded to an extra set of BB7's I had in my parts pile ... and they were garbage, which I knew they weren't. Found out the factory stuff was not compressionless and that was the problem reaching all the way back on that longtail. Almost every aftermarket brake cable housing on Amazon is compressionless (the good Jagwire kits, for instance). But on that same bike, a set of Maguras went on and I have never regretted them.

Yep, a reverse trike.

Are the Maguras mechanical?( Had a Magura throttle on an old Wacker tamper I ran)

It doesn't have to be great just adequate.

No they are hydros. Are your brakes a single lever pull that splits off to pull both right and left at the same time? If so then you pretty much have to go with your cable-pull hydro idea. There may be such a think as a hydraulic brake set that balances pull between two calipers but if so it can't be anything but stupidly expensive.

Yes they are,if they are adequate its fine only looking for even wear on the brakes( it may even have regen!)
