Shimano Road Hydraulic Disc Brake Fitting Tips

[@petee1968]

Mate, every time I search for a bike-based subject, your videos are the ones I find most useful! You're brilliant at what you do! Thanks, and keep up the good work!

[@petee1968]

While I've got you... ;) I watched your video about using MTB callipers with road levers, again very useful, thanks! My question is this: Are all Shimano road levers compatible with all Shimano MTB callipers? Specifically, could I use GRX hydraulic Di2 levers with MT520 four-pot calipers, or SLX four-pots, or XT 8100 four-pots?

[@TheAnon232]

Same!

[@zhanchi90]

I'm obsessed with your channel since stepping into the territory of bikewrenching a few weeks ago. Helped me tremendously on quite a few occasions, so I must drop a big Thank You here!

[@qa23tmzx]

I dont get the part about the barb - do you leave it in the end of the brake cable when you put it into the shifter or remove it? is it inserted only when you cut the cable to length?

[@zerraktardun9904]

simple and straight to the point, thanks

[@EvinKaless]

Sweet!! I was unsure about a NEW installation with the integral olive. This was exactly what I was hoping to find! Thank You!! 🙏

[@braulioperez181]

Excellent step by step explanation. Seems to be easy but require kin skills as you have. Thanks for your video.

[@goodoleme747]

agreed...he's got a good way of explaining things. easy to understand

[@dvs70]

Thanks again, another question answered a year after my initial view. I was wondering why installs I've seen do not add an olive on new shifters. Impatiently awaiting my 12sp Ultegra groupset. Thanks again!

[@petersharkey2119]

Just like school except I was really listening thanks for all the info

[@bobodapopper]

Your videos are always so helpful. Thank you 🙏

[@DavosPessos]

Dude you're brilliant!!! The front clip and that yellow thing j jad no idea what they were! Now I do👍🏾👍🏾👍🏾 much appreciated on this vid👍🏾👍🏾

[@edge23310]

Your videos are on another level mate, love the detail and step by step walkthrough! Thanks for taking the time to make these 😘 Any chance of making a short video on how to service the bearings in a DT Swiss hub using the locking ring nut to remove the inner bearing behind the ratchet? The tool just arrived and it's my first time using it haha.

[@FreeToCycle]

Thanks!!. Which DT wheel have you got?

[@edge23310]

@@FreeToCycle Thanks for replying 😊 Its the 240 hub

[@eskiljakobsson3953]

Thanks these videos are really helpful. Good work and thanks a bunch!

[@Outdoorsyfella]

Thank you for making this video, exactly what I needed. Very helpful :-)

[@ernestojrpatricio5030]

Thanks for this! I got a question, my friend accidentally squeeze my brand new levers, the yellow seal pops out as well as the oil inside it. When I checked the inside of connector port of the lever, I couldnt find the olive. It is just loosely inside when manufacturer installed it? You think I should buy an extra olive before I bring it to shop for installation? What could be the problem that may cause? Thanks

[@sangriastudios]

very good video, well done, like being back in school. Good tips so not to damage the parts. thanks for doing these.

[@verdeboyo]

Nice one! I'd like to replace all the Ultegra disc brake caliper mounting bolts on my Bianchi Oltre Comp with titanium, so I may have to watch this again👍🏻

[@c.initiative2705]

Just the video I needed! Thanks from the Black Forest, FRG

[@Flyboard12345]

thank you for your explanations, they are of great value.

[@cyclingadventure1804]

Very helpful, thank you for sharing.

[@kevbrown7137]

Great tutorial as usual.. Ive just purchased a GRX upgrade for my bike and noticed as with your video.. The rear caliper has no 140/160 packer piece... Is there a reason shimano do this.. Thanks

[@DonJon55]

I don't get this, some frames might not require one. Mine did, quite frustrating when you think you have all the parts to finally build your bike.

[@kevbrown7137]

​@@DonJon55on further investigation the spacer is only required with a 160mm rotor... 140mm no spacer

[@DonJon55]

@@kevbrown7137 I bought complete GRX groupset that came with 160mm rotors but no rear spacer for 160...go figure. At leat they included the longest adaptor bolt of the three possible which is useless on most frames. Like how much it would cost them to give you all 3 options? Oh and no bleed adaptor, of course.

[@kevbrown7137]

​@@DonJon55agreed, i just used the old adaptor and bolts.

[@richc5638]

Thanks for the video, very helpful. One question, I bought new and hose is already connected to rear caliper as yours is, is the olive already in there crushed to the hose or would I have to take apart and put one in?

[@FreeToCycle]

Yes the olive is already on the hose!

[@CynicalManInBlack]

I am changing GRX levers from mechanical to Di2 but I am keeping the calipers with hoses. Do I need to cut the hoses parts with old olives and reinstall the pins before plugging the cables? Or will it still work with old olives on the cables? I am assuming there are other olives inside the Di2 levers installed as well.

[@FreeToCycle]

Always best to fit new olives to the hoses! They may start leaking using the old ones.

[@CynicalManInBlack]

@@FreeToCycle Makes sense. Is there a way to take them off somehow or should I cut the hoses?

[@FreeToCycle]

You can cut them off if you’re careful! I do mention how to do in this video kzbin.info/www/bejne/f5PakIeobt9-atk

[@nickquirkeart3287]

Hello can you maybe give me some advise. Will a di2 8050 disk brake lever work with a 8170 brake? Thanks

[@FreeToCycle]

Yes!

[@nickquirkeart3287]

@@FreeToCycle it’s says online this is a mechanical brake and the 8170 is a hydraulic! Should have just stick with my rims brakes. Thank you for your response

[@nickquirkeart3287]

@@FreeToCycle sorry my levers are 8070 not 8050. Will these still work with 8170 hydraulic disk brake?

[@megane230f1]

i have a cannodale topstone 4 running promax render brakes which are horrendous, im wanting to put grx 400 calipers and levers on it, do i have to change all the running gear on it as well? it has microshift 10 speed advent deraileur on it, or can i just put the brakes on it, ive read about pulley system been different so the the shifter on brakes wont work, any advice would be great

[@FreeToCycle]

You will need to change everything to Shimano!

[@megane230f1]

@@FreeToCycle many thanks for the reply, very much appreciated 👍🙏👌

[@rayoutair4433]

Did you cut the head of the cable that came attached to the breaks?

[@richardbryanesq]

I cut mine because it was too long, and having a hard time getting the system to work right. The needles to use, and the connecting bolts, are not the same for all Shimano brake hose systems. The gold needles and the silver ones are different part numbers and slightly different.

[@bogeyman9979]

Thank you brother, I thought they forgot to give me the olive

[@oquemaur]

Anybody know what the 2mm grub screw at the side of the hose connection point is? Locking the olive in place?

[@richardbryanesq]

Excellent; thank you. I've been trying to get my hydraulic brake system setup and it seems there are two common and different Shimano hose and needle and bolt types. One where the olive is already inside the brake lever, as you've illustrated here, and another where the olive has to be put on. And there are two different needles available depending on which system you have. And different connecting bolts. Very frustrating. Thanks agin for the video. (Maybe use green gloves? Sometimes the parts are hard to see against you black gloves).

[@nosegrindv4951]

thank you!

[@fractalofgod6324]

Great video and very helpful. Not a criticism but the black gloves on the black brakes makes it harder to see what you are doing, it blurs the lines. Maybe also so more close up video but like I said it's a really helpful video. Cheers for sharing.

[@toht5058]

Can i put my mtb mt200 hydraulic hose to the hydraulic brake lever sti rb? Is it compatible?

[@marinosupriyanto]

it is compatible

[@rickvdvorstenbosch1321]

Do you get a 160mm spacer for back brake in the kit to ?

[@FreeToCycle]

No not included.

[@liambourke6871]

whats the difference between mechanical and hydraulic dis brakes?

[@shaunsmith3660]

Are you based in Bristol? Sounds like a Somerset accent

[@povertyspec9651]

They should come from the factory with the hose connected to the levers instead of the brakes.
