The RS785 calipers (1st gen Shimano road discs) on my winter roadie are doing the dreaded leaky, squeely, honly , non stoppy thing, so I need to replace them. (been round the houses with trying to fix them. 99% sure its microleaks.
Direct replacement calipers are still just about available, however it looks like Deore 6100 calipers should also fit, for rather less cash - they appear to have the same non-banjo "plug in" type compression fitting for the hose.
Can anyone confirm the hose threads are the same?
Do they take the standard Shimano 2-pot MTB pad? They seem to, but there is/was a generation of deore brake that took something different. (the missus bought one by accident)
Thanks!
I cocked up the other day and bought a post mount shimano brake when I needed flat mount, so I have a "Shimano BR-RS785 Road Post Type Hydraulic Disc Brake Calliper" in the post to me.
Cost me £60, but am open to offers....
Yep just take your old calipers off and put 6100's on.
I'm running m6100 at the front and m615 on the back of my winter road bike 🙂
Oh and yes, m615, m6000 and m6100 all use the same pad design (latest two pot pad design).
@cp - no issues making the different hoses work? I've got BH59 hoses, the new calipers are apparently designed for BH90...
What levers have you got?
I'm on currently on r8020 levers - at that end there is variation as the more recent levers use a flanged bolt connection, but yours use the same threaded bolt thing as the calliper end. I'd previously used RS505 levers (same hose fitting as yours) with M785 callipers. Plenty of people using "MTB" callipers on road levers.
The difference between bh59 and bh90 hose is the inside diameter, the outside is the same. They use the same olives and threaded fittings at the calliper end (for threaded callipers) but the insert is unique to the hose (bh59 uses the brass coloured insert whilst bh90 uses the silver insert).
Sorry to jump onto this thread but I have the same callipers and am concerned about their long term availability. So will any post mount mtb 2 piston shimano calliper work? Thanks
