The rear brake seems too loose to work, which is quite dangerous! And I tried to use the tool to tighten the rear brake, however, the NCM stupid design makes it impossible for the tool to stick in and tightens it. Any idea how does it work or do i have to buy a specific tool or find a bike store to get it done?
How to tighten the rear brake of Moscow
- Thread starter kirksea
- Start date
Sorry for the confusion. Just Moscow standard.
I mean the the rear brake is so loos that I can't stop the bike when I want. And I checked some instructions about how to tighten the brake, the thing is the screw that should be easily accessible and tightened, actually is not possible to reach. That's my concern here. Thanks

I had the same problem, NCM refuses to admit that you need to tighten that screw when infact it's written in the brake tektro manual, also it's just the way to adjust mechanical disk brakes. The screw that can't be reached because the motor is in the way is the one the controls the inner pad adjustment.
You can either find a hex key with a very short head (I couldn't find it) or just cut one yourself.

is this what you're referring to?

You’ve got two easy ways to tighten the brakes , and a slightly more difficult way . The brake lever mechanism at the handlebars has a silver barrel screw that he cable runs through , you can turn this by hand . Unscrew it and the cable tightens , the brake pads move closer to the disk . Where the cable joins the rear brake mechanism same thing , unscrew the black barrel screw that the
cable runs through and the cable tightens . You can tighten the brakes quite a lot this way .
Slightly more difficult way if the above doesn’t close the brake pads enough is to use the crimp that attaches the cable to the rear brake mechanism to tighten the cable .

Yeah but you can also use the inner pad adjuster which on this bike can't be accessed because of the hub motor, that's the issue.

I just took an allen key that was the correct size and then cut it down to just about the minimum length I could and now it fits in the inner pad adjuster - I just keep that allen key for adjusting my rear brake.

how did you cut it?

I just put it into the vice with the amount that I wanted to cut off sticking out of the side then cut it flush to the edge of the vice with a hacksaw. A little bit of filing just to smooth off the edges and it works perfectly. I use the technique that NCM describe in the manual to centre the rotor between the pads but then adjust the inner pad as need with the shortened allen key in just the same way as the front brake.
Exactly, thanks a lot for paraphrasing for me. As English is not my first language, I was not able to describe the exact problem. You did express the problem I encountered.
Thanks! I have already tried the easy way and after several days of riding, the brake loosens again. That is why I am thinking about the second and hard way, which should be the best option. But as described by the other 2 above, I do have the right tool for it. Just can not understand this design, which is so inconvenient for riders!

I was always told that the barrel is really only for adjustment while you are actually out riding

Tell that to NCM, they say the opposite!
I'm thinking of sending this thread to them.
That would be great! At least they should include a proper tool the adjustment. Frankly speaking, I am not satisfied with what NCM offers for the bike and also its service. If I had another chance, I will not buy NCM.lol

Adjustment only takes a set of allen wrenches which should be part of any bike tool kit. That said, I have to say, I´m very disappointed with
the stock rear brake on the moscow. Your problem is not with the mounting bolts for the brake body, but with the adjustment bolts.
Mounting bolts are at a right angle to the wheel; the adjustment bolts are parallel to the wheel. Having done so today, I replaced the whole
damn brake body with an Artek 160mm. Installing & fine tuning the adjustment is a kinda delicate procedure. If you´ve never worked on
disc brakes I suggest having a professional deal with it. I noticed on the old body I took off that the mounting base had been back cut
a file. I had already had to do the same thing to install the Artek, which I just happened to have left over from a kit for another bike. I´ve had
no issues with the front 180mm, but the 160 rear has been a nuisance since the 1500 mi. mark. If I were you I´d have a professional put
on a better brake body. I am also of the opinion the the rear tire, at least, should be a smart sam plus, & not a regular smart sam. I´ve not
had a rear tire issue since having done so. I still like this bike a lot, but I hope Leon Cycle will adopt these changes in future.

They all adjust; but instead of 2 pads loosely secured by a cotter pin, the pad screws into a fixed position, no chatter, better adjustment set up,
but a bit harder to dial in. I had to add small lock washers to gain height above the edge of the disc, it was a very close tolerance. if you don´t have an owners manual, ask Leon Cycle for one. it has a diagram showing the adjustment bolts as well as a lot of important & useful information.
