The level of production on this is wonderful! Keep it up and keep spreading the knowledge, we are so appreciative!

Brilliant video in showing how roller brakes are constructed. However would be wise to add that this service won’t fix brakes that are worn out - the brake pads do get used up and then disassembling, cleaning etcetera will make no difference in restoring brake power, only replacing the whole brake will do, since Shimano doesn’t offer internal spare parts for roller brakes. Still a very good video.

Great comment. That completely matches my experience with those brakes and that is exactly what i was thinking when watching that video. The operations shown here are great to clean the dirty brake up (though i prefer to grease the pads before installing them in to make sure the grease distribution inside is even from the very beginning) or to help assemble one working brake out of two damaged ones. However the part with diagnosing and describing typical problems with this type of brakes would be useful and could help people out there to save some time trying to repair the brake with worn out pads.

Thanks so much!! For me the hardest part was the black backing plate, what worked for me already a few times: first the two 'barbs' on the backing plate that need to grip behind the aluminum need to be positioned, then the backing plate can be rotated back and forth until things fall into place.

Thank you for the video, just currently getting my Dutch bike retrofitted with roller brakes, helpful tutorial just in case any of bike shops I come across might not be able to help with it being a rarity brake system. Wasn’t sure if it was in video or others, but I’ve seen somewhere that people use the grease for maintenance. How often or frequent should the brakes be greased with the special oil? Is it like a regular, or when brakes are becoming less serviceable or something else?

@cyclemaintenanceacademy 5 месяцев назад

hi, thanks so much for watching the video and for your kind words! I'm really happy that the tutorial was useful to you. As for greasing roller brakes, I've just published a new video on how to grease roller brakes. You can find it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4BZe8HXqJA4.html I hope you find it useful🙂

We have a 22 year old Gazelle cycle (bought in the Hoek von Holland cycle shop) and the roller brake at the back has been iffy for at least 10 years. New cables all round not fixed it. Fortunately, the front brake is a regular Shimano V-brake. Cycle shops here in Cambridgeshire don't know how to service these brakes and are not interested. All is now clear to me - the only thing I'm not sure is - why is Gazelle not paying you to make them such a truly excellent video?

Hi, thanks so much for your kind words! I'm delighted to hear that the video clarified things for you. Sorry to hear about the challenges you've faced with the roller brake. Hopefully, after a good service, it'll regain its full braking power. The main goal for this channel is to reach as many folks who might find my videos helpful. You can lend a hand by sharing this and other valuable videos with your friends and on your social media. It really helps the channel connect with the RU-vid algorithm. If you have any more inquiries or need further assistance, feel free to reach out. P.S. you may also find my newest video on how to lubricate a roller brake helpful.

@@cyclemaintenanceacademy Shimano claim that rollerbrakes are non serviceable parts so bike shop won't dissemble, only replace.

@user-ri6lw4ly8y 2 месяца назад

Hello! Is there free play on the pedals back on this brake or does it also have a foot brake function?

@cyclemaintenanceacademy 2 месяца назад

Hi, and thanks for your question. This brake allows freewheeling and it doesn't offer a back pedal braking. i hope this helps🙂

@Obscurity202 Месяц назад

How do you know if it's worn out? How do you troubleshoot the braking outside of simple disassembly and reassembly. Thanks!

@cyclemaintenanceacademy Месяц назад

Hello, thanks for your questions. If pulling the lever on the roller brake fully doesn't elicit a response from the brake, it's likely worn out. Regrettably, Shimano doesn't provide replacement parts, so you'll need to replace the entire brake unit. As for troubleshooting brake issues, what specific areas would you like assistance with? Disassembling and reassembling often resolves most problems.

@reiniero123 4 месяца назад

No need to apply grease during reassembly? Only after fitting the wheel? Mentioned link for grease instruction links to wheel montage video?

Hey, appreciate your comment and the reminder! I've added the link to the video on greasing a roller brake. You can now access it directly from the video and find the link in the description as well. Thanks for pointing it out!🙂

yeah it's probably better to the brake shoes while you have them right in front of you

@fraaggl 2 месяца назад

what about when you clean and grease everything but the brake are still sloppy ? The main pad inside the brake can they be changed ?

Hi, and thanks for your question. Unfortunately, Shimano doesn't offer internal replacement parts for these brakes.

There is a ball-bearing intead of a nut on my rear wheel which has a BR-C6000-r installed. If i tighten the outise nut to fix the wheel, the break stops working (doesn't go back after breaking).* Can you make sense of that? Do you also have that sealed bearing? I couldn't find anything about it on the shimano homepage.

@cyclemaintenanceacademy Месяц назад

Hi, thanks for your comment and apologies for not getting back to you sooner. Can you let me know the model of the hub?

@Starnger Месяц назад

Could it be that what you have does look like bearing but in fact is just a metal ring with rubber ring fitted inside? Shimano often uses this kind of spacers instead of normal washers. In my experience in cases like yours best is to check what causes the friction leading to the lever getting stuck. Typically it is either deformation on the cover caused by mechanical damage, or just too tight nut tightening on the outside. In first case just form the metal on the cover back with pliers or hammer. In the second case use two nuts on the outside instead of one and counter-tighten them so they sit tightly on the axle, but leave just a tiny bit of loose fitment on the brake itself. Most of the time combination of those two methods would allow you to fix the issue.
