[MTB maintenance] Oil change attempt on a cable-pull hydraulic brake caliper

I have tried to completely change old brake oil with new one on a cable-pull or cable-actuated hydraulic brake caliper. You have likely seen the same calipers with different brand names. This type of calipers are recommended only as upgrade from V-brakes and should not be considered as cheap alternative to a proper hydraulic brake system with dedicated calipers and levers.

If you know an easier way to completely flush old brake oil on this type of calipers, then let me know in the comment section of this video. Thanks.

Wow, amazing informative video! I liked it how you did not just show the tutorial, but even made an example about why its difficult to bleed this system. Great work!

You made this way more complicated than it actually needs to be

[brucemcleod]

But do you find these superior to just cable actuated brakes? Thank you for the detailed video and your explanations and diagrams go to a extra level

Very informative video! I was contemplating getting a cable pull hydraulic, but seeing maintenance could be so tedious, I should just get those full on hydraulic ones instead. Thank you! Cheers!

Which part of the video where you loosen the adjusting bolt?

Hi, currently my semi-hydraulic brakes are failing, the pistons do not return to their place, do you know how to fix this?

[Honir]

a complete nightmare to service thanks for this video i don't think its worth upgrading from mechanical to this specific hybrid system maybe there are other hybrid with a better design but these sucks they are worst than full hydraulic to service good to know ill avoid these

wouldnt it just be easier to use a regular hydraulic bleeding kit. just open the bleeder and fill screw and flush with the kit.

Can we use dot 4 or 5.1 instead mineral oil in these?

I genuinely do not see what he is trying to show. Those callipers are easy to bleed or replace the fluid with the correct bleed kit. It is, without doubt, possible to bleed them without the correct kit but for a few pounds, the job is made so much more easy.

you can't get hydraulic brake levers with a motor cutoff switch for ebikes without spending almost $200... which is why this style of caliper was created-- to allow hydraulic braking using the ubiquitous common mechanical ebike brakes levers with built in motor cutoff switches
