Shimano Road hydro levers with MTB calipers?

Is there a compatibility issue with Road levers and MTB brakes? I need post mount calipers and they are not easy to find and there are always plenty of MTB calipers going for sale 2nd hand.

A bit of googling suggest this should work but if anyone has real life experience of this then please let me know of said experience.

Run my rs685 levers with Deore post mount calipers, no probs at all. MTB calipers are compatible so you can take your pick.

That is exactly the kind of thing I wanted to hear!

Or if your funds allow, you can get the Hope RX4 callipers, expensive (bought mine from germany) but they are great, much better than the Shimano callipes they replaced being 4 pot design.

Can you use hope calipers with Shimano hydraulic STI given they run different fluid for starters?

Yes RX4.

Yes, they do a Shimano compatible version and a Sram compatible version.

Run my rs505 shifterd with XT 785 calipers- brilliant 🙂

Just to be contrary, could I run the RX4-SH calipers with standard Shimano MTB levers (SLX)? I’d like a nice pair of silver calipers.

Had been wondering this myself, I really don’t see why not. Bear in mind though the RX4 uses smaller pistons than E4 so power probably be won’t be as much.

Make sure the hoses/olives are all the right size to talk to each other- Iirc some of the road setups came with skinnier hoses. Can’t remember the details, sorry.

As far as mtb callipers go, crack on, I’ve had no trouble with it

The RX4’s are optimised for Shimano or SRAM road levers, down to having different sized pistons on one to the other.  I doubt you could plug them into MTB levers 100% successfully, Hope tried the X2 caliper on road levers and it was no good.

I’ve got a set of Post Mount Shimano BR 785 callipers that I’m about to sell as my new frame and for is flat mount.

Email in profile if you’re interested.

Can you use RS685/785 levers with Shimano 4 pot brakes?

I managed to get some 105 levers and my friend has promised me some slx calipers. With regard to hoses what do I need?

Do the lever require skinny road hoses or will mtb ones be OK? It’s the first time with this set up so have no idea what to expect!
