- Bleeding hope brakes can be tricky but set your stall out and get some proper tools you will find it easy and rewarding, Hope sell a bleed kit for these brakes but it can be done without, The Yorkshire Bike Mechanic shows you how. Check out my other videos, please subscribe and share.
My Tech 4s came with the extra top cap cup for mounting on with the cup and plunger so was happy to see this included, not sure if it was a special offer pack but very easy and quick tool
if you get the bike in the stand and rotate the front high and the lever you are bleeding turn towards the seat .. A toe strap helps. gets you all nice and flat (saw it on the hope vid)
Love my Hope brakes so many different ways to bleed them. Think next time i will have a crack at this way i want to flush the whole system out completely with new fluids and this way would be perfect for that.
One thing you missed and its such a tiny thing, the bleed nipple can hold a drop or 2 of fluid so its a good idea to teist a bit of towl and poke it inside to pick that drop up. I bet you dod it but forgot to say it.
Brilliant informative video super clear thanks.
Apart from removing air in the system I thought one of the reasons for bleeding brakes was to flush out old fluid and replacing with fresh, or is this not necessary? Love the channel, toodle pip.
Hi, Thanks for watching, brake fluid and mineral oil goes grey and thin when spent, you can usually tell pretty quickly what condition the oil is in. Also by filling one syringe full and the other nearly empty to can still make a full fluid change and still remove air.
Really informative video.....and no irritating music in the background!
Thank you
Their brakes do last forever, I have been a Hope brake lover for about 30 years now. My inventory of spares is quite mad, if anyone is looking for old school Hope bits give me a ring. My Wifer will be thankful. Be super careful with brake fluid is my mantra. My latest build is Mondraker Foxy R with Hope Brakes and their vented rotors Ohlins suspension, life is so good now. 👍🏽
Yea I want the strongest brakes for my emtb and thinking about the hope tech 4 v4
I am in need of a new Lever for a Mono. Just next to the bracket it has a crack😢 don't suppose you have one.
@@PsyMongSki I wish
@@shafiqjan1474 they are so hard to find, I have what looks.like a brand New full mono brake unit and in storage it got something heavy dropped on the Lever and it cracked. I have a box full of old 90s and early 00s mtb kit that hopefully will be worth some.good money in the future. Even got a few prototype bits that were never released. A friend of mine worked for a well known mtb company and he would bring me random bits when he came over for my little collection box.
Shame he didnt work for hope.and bring me my god dam brake lever lol
Great british video mate, id like to drink a pint of beer with you somewehere in northern uk 😊
Hi, thanks for watching and your comments, It would have to be a shandy I cant handle anything else.
Thanks for the great video. I'm changing my brake pads which are very low. I'm having a hard time getting the Pistons fully pushed in. Any tips? And just to confirm, when changing the pads, I don't need to open the top reservoir do I?
This really helped me get my brakes working great again. The tip about centralising the pistons at the end helped massively. Really well explained, thanks for a great video!
Hi Jack, You are welcome, glad it helped
Any reason to use dot 4 over the 5.1 that hopes come factory bled with?
Simply it’s a little cheaper and perfectly adequate for bike Mtb brakes, 5.1 has a higher boiling point.
@@TheYorkshireBikeMechanic Any issues with gelling? I had always heard never to mix 4.0 with 5.1 for that reason.
@@JuanRamirez-hk8sf Hi, Thanks for watching, Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.
thank you very much for this kind Sir! I appreciate your effort on making this video - subscribed!
Thank you
I just got Hope brakes which are brilliant and your video is so easy to follow with good video of each step. Very well explained
Glad it helped, thanks for watching.
What syringes are you using? All the bleed kits I have use tubes that don't hold on to the nipple as well as yours or others that I've seen so I think your tubing is smaller.
Hi, we use Terumo Syringe 20ml Luer Slip Eccentric tip x Box of 50 × 2
glad i found this site!! i have some old hope M4's that need a refresh they have braided hoses too :) really good job with your explanation i have watched a few really bad vids
Glad I could help!, thanks for watching
Big Mistake (21:35) !!! You trapped the air in the reservoir. Check out the hope bleeding instruction. There you can see the difference.
Hi, Thanks for watching and your comments.
Hi, i have a question, i lately rebuilt levers and calipers with new seals and pistons, fitted braided hoses on them and did everything as you explained but it seems like there is some air trapped inside still, since pistons of the caliper are new and pushed in i cannot manage to get them moving outwards, lever goes fully to handlebars and i dont know what to do anymore, tried it 3 times and still no progress towards pistons moving out.
Hi, A stupid question but when you rebuilt the levers did you put the one wate washers on the piston right?, can you pass fluid freely from the caliper up to the lever and does the reservoir fill up?, when the reservoir is full can you press the lever and does fulid fill the syringe on the caliper?
@@TheYorkshireBikeMechanic ty for asking, i did put washer on the right side, i sorted it out and bled them correctly, problem was that i did not put bleed nipple on the caliper to be highest point of the caliper during the bleed and it got lots of air stuck inside the system, now they work as new :D
Dave, your instructions helped me dead on. My only issue now is, with the wheel off, the brake feels exceptional but once the wheel goes on lever gets spongy
Hi, thanks for watching and your comment. with the wheel in use a fine screwdriver or pick to centralise the pistons
@@TheYorkshireBikeMechanic thanks
Sorted my problem 🙏🙏🙏
A up Dave …I always thought you pumped the lever to get the fluid though …..your way seems nob on ,will try it next time I do me v10 hope brakes ….got a right horrible squeal on me Kenevo sram brakes ,any ideas how to sort it would be greatly appreciated…cheers mate 👍
Hi, as long as there is no air in the system this is the best way to do it, if you pump the lever it and encourage you to add more fluid then when you put new pads in the pistons don’t retract fully, it’s also best if you put bleed and put new pads in at the same time.
Bloody good bleed 😮
i can ask my mate in netherland's to buy the part's for me and ship to me as a gift so don't get custom's charge lol
Hi, Thanks for watching, Im not sure, Ive no import knowledge
Amazon fella next day
Hello dave buy the hope easy bleed kit
Hi Ashley thanks for watching. We have Hope kits but I thought it better to do it without as not everyone has one, plus it’s give you and idea of what’s happening in the lever reservoir. To be honest I prefer to do it this way, the kit can be a bit messy.
great video, really clear - thanks! Where do you buy your syringes from and do you buy them in bulk?
Hi Paul, we buy them in bulk, www.medisave.co.uk/terumo-syringe-20ml-luer-slip-eccentric-tip-x-box-of-50.html
they are only used once then disposed of, that way we dont get cross contamination and the silicone tube sticks better to the end when new
Thankyou...
Is that a tool wall or stock wall?
Hi, sorry not sure what you mean
great video thank you
Glad you enjoyed it
Hey buddy what is your honest opinion on hope brakes, and trp dhr-evo. Im torn between the two and im starting to see negative abt quality control on the hope e4 v4 and not much negative on the trp
Hi, Thanks for watching and your comment, Hope all day long but they are not a fit and forget brake, they take a bit of looking after.
siibaii awat aku bt mcm ni xjd?tetap ad angin jugak?tgk dia bt senang ja 😫
Informative and helpful video. I love my hope e4 although both times I've had to replace pads retracting the pistons has been ridiculously hard, meaning it took a lot of force with a heavy blade out of my air chisel. I gave thm a good wash beforehand so I wasn't pushing gŕit back into my piston seals, but they were still really hard to compress......any ideas? Any insight would be appreciated. Thanks.
Hi, Thank you for watching and your comments. If your levers feel good then your caliper is in need of a service, pistons out, a good clean, new pistons and seals.
Brilliant. thanks so much. it worked a treat
I have tech 3 brakes. I'm wondering if I can mix match them with tech 4 levers ?
Hi, Thanks for watching and your comments, yes you can
Complicated and unefficient process. Can be simpler, and is not Hope process.
Hi, Thanks for watching and your comments
Great video, I was always debating to use a syringe in a similar way to the Shimano method for the hope brakes. Seeing this absolutely helps. I already have the easy bleed reservoir but the hope method was always messy and cumbersome using the lever and bleed nipple back and forth. Thanks for the video and keep up the good work. 👍👍👍
Thanks for watching and your comments

Hi, Thanks for watching and your comments
Just a thought, maybe degas the dot fluid, 🚴
Have Tech 3s on my 2018 V10. And Tech 4s on my 2020 V10.
Thanks for watching and your comments
Could I ask if you take on customer a customer for a service on hope brakes? If so could you give me your details? Thanks
Hi Gavin, sure, tel 01422 766086
I do have the bleed kit for the new Tech4 brakes. Used the Hope Bleed video to bleed them after shortening the hoses. I just saw that bleeding the caliper I did wrong I guess. Did not fix the lever on the bar and pushed the pistons back.. After doing that 3 times on different days, the lever still feels "spongy". Might try this again like you did it. Or the lever feel is just as it is with Hope brakes coming from Shimanos.
Hi Thanks for watching, let us know how you get on.
@@TheYorkshireBikeMechanic hey, so I tried it again after watching your video. The lever feels the same afterwards. There was no air behind the pistons. I took the bike for a ride after that and while the lever feel more squishy than shimanos the braking power is top notch. So I guess I was not used to that feel. Thanks a lot though. Will use your method for future bleeding
Where can I find the spare parts for the hood brakes online?
Hi, can you be more specific, sorry for the late reply.
Excellent video mate....... saved me a right ball ache. I bled the back brake a couple of times and it felt fine until I rode the bike, and then it went spongy AF. Followed your tip for getting air out from behind the pistons and now it's solid. Keep up the good work my man!
Thanks Alex, glad you enjoy them
Enjoyed watching this very much and i dont have hope brakes 😂
Thanks, great brakes but need maintenance
Helped me a lot with my e4s, thank you
Glad I could help
My piston won't move how do I push it back without damaging the caliper ?
Hi, Thanks for watching and your comments. it could be a number of things, too much fluid in the system?, misaligned piston, debris around the enclosure, damaged seal. sorry I cant be of more help
@@TheYorkshireBikeMechanic Hi , thanks for reply , the brake is brand new and piston must have came out during transport .
like your instruction and i want to try it but i have a question..
while using the syringe that is on the caliper side, do I need to press and pull the syringe for a few times or just need to pull (suck the oil) it only until no more air bubbles come out?
Hi, it’s a case of working both front and rear syringes at the same time one to pull and the other to push them opposite.
@@TheYorkshireBikeMechanic is it ok if me push the lever to handlebar and push back the piston for several time to make sure the bubble really come out at piston area?
Very useful tips there lad. Shall be doing this with my v4s
Glad it helped
Amazing Tutorial Thank you very much.
Thanks for watching and your comments
Hi can i ask I'm shortening my brand new rear hope e4 hydraulic disc hose, i don't have a stand can i complete this with wheel on and do the pads need to be open or closed cheers.
Hi David, you don’t need a stand to do it, if it’s not internally routed fit the brake then shorten at the lever end. Leave the calliper as it came out of the box. Shorted then re-connect it, don’t press the lever, push the pads back this will send any air back into the lever lever then set them up as normal
@@TheYorkshireBikeMechanic i have fitted the brake, i will just shorten the hose at lever end as shown in video where I'm confused is what position the pads need to be in. The video states pads need to be touching cheers
Just watched this video. It was really helpful 🤘👍🤘
Hi Martin, Glad you liked it!!
Great video
What size rubber tube is it for Hope
Many thanks
If I remember right its 3mm internal silicone
Thanks
DOT 4 for HOPE Brakes???
Hi, Thanks for watching. Hope brakes are designed to operate with DOT 4 or DOT 5.1 brake fluid. These are both glycol based fluids and can be mixed, although it's advisable to flush the line through with the new fluid to maintain a constant performance. DOT 4 will typically have a lower boiling point than DOT 5.1 and be more viscous (thicker).
Thanks this was helpful!
No problem!
Hope use dot 5.1 or mineral oil.
Hi Russ, Hope only use dot 4 or 5.1
@@TheYorkshireBikeMechanic all the hope brake I service use dot 5.1 as the boiling point is greater. The hope rx range uses mineral oil.
Nice work buddy
Thanks 👍
Top work fella
Thanks 👍
Really informative and helpful definitely a like for me
Glad you liked it
brexit 🙄
Thanks for another top vid Dave,love hope brakes have had them on most of my bikes, coming from a motorcycling background I find them to be most motorcycle like ,as you say easily serviceable , all parts available and the customer service is second to none.
Thanks james
I used to run dh4 hopes back 20 years ago and always loved the feel of them,do modern hope brakes have a similar feel? I’m looking to swap to hope brakes on my specilized kenevo from sram,I’m bigger guy so would you recommend e4 or v4 brakes ? @theyorkshirebikemechanic
Hi, V4s are an amazing brake as long as you use the hope rotors to match, on an ebike they are amazing, pricy but good. however from experience hope are not a fit and forget brake and not everyones cup of tea but keep them maintained and aligned they are they best.
@@TheYorkshireBikeMechanic thank you for your reply
