First off thank you for your video. It’s straightforward and to the point. The only thing is that being a visual person trying to watch exactly what your doing is really hard with the sub titles in the way. Giving you a big thumbs up and I already subscribe so keep up the good work

Very good video step by step u can’t mess it up highly appreciated having the torque specs

Very important to mention… When the piston is in the rest position, the brake fluid will be balanced via The compensation hole. This compensation hole is very small, clean this compensation hole with a very thin wire of copper, if it would clog… you are guaranteed a dragging caliper, this has already happened to me twice!!! with the Honda CBX 1000. Stay Safe.

Excellent excellent excellent video I love how you get to the point! And are detailed !! very well done there's so many people on YouTube that want to hear themselves talk thank you! where can I get that kit? I'm going to try the link below but not sure if I can use the kit because I could not break free the Piston with the o-rings and spring.

Hello Sr. Thanks for the explanation.. I do have quite a problem with taking apart my rear master cylinder in two specific areas: 1. I can not take out the piston, as the circlip is completely rusted and I can´t take it out. The circlip is still in it´s place so what is left from it is in the inner lip of the cylinder holding the washer... any ideas? 2. How do you take out the reservoir hose mount (I did remove the circlip) but the mount seems to be stucked there and when applying strength doesn´t come out and bends a bit, so I´m worry to break it... thanks (I have pictures if there is any option to share)

I did this step by step, however after assembling I attempt to bleed the brakes to no avail. The piston goes up and gets stuck on the first press of the brake lever, any ideas?
