Hi everyone,
Just received a new set of hope tech m4's. I have noticed in the back of both callipers there is a small hole right next to where the disk would run through. To me it looks rough and not right atall. I will try and get a pic.
In the meantime, are anyone else's like this?
Thanks
Hugh
I think every Mono M4 caliper I've ever seen has it. I always put it down to a necessity of the CNC process.
Its where the transfere port is drilled between the piston chambers. If youve ever seen one of those calipers stripped down then it all becomes clear, and then you see how good the machining really is......

It's normal. Don't worry about it they all have it.
Thanks chaps, saves me sending them back.
Hugh
