Hi Mr Spicy. Good Instructional video. For a non-full time mechanic you have done a blinding job. It was fun, educational and took all of the "mystery" out of the job. All I'd ask if that if any of you attempt this yourself and encounter issues, stop and consult/refer/hand-over to a professional, brakes are not something you want as defective items at any time while riding a motorcycle. - Great video.

Your timing is impeccable. I was needing to tackle this job today and was just about to look up on how to do it!

[Nick-vxer]

This is an amazing tutorial for this job. No silly jumpcuts creating doubt, very detailed easy to comprehend explanations at every step. Although I learnt this job a long time ago I still watched it as it is nice to watch a perfectly executed maintenance video.

Thank you Spicy.

Awesome helpful video, thank you! Just getting ready to tackle this project on my 93 Honda Helix. Really looking forward to having some good functioning brakes again.

Great video, thanks.
One very minor point that hasn't been mentioned. I wouldn't rattle the hose when refilling and bleeding. Air rises and fluid drops. It could make any air in the hose go back up the system.
Very helpful though.

Outstanding! Cracking great! Thank you and Cheers!

got two sets brakes to do - honda vfr 400cc nc 21 - new seals Yamaha dtr125r master cylinder both brakes seals - very helpful blog

[roblydiate]

great little tutorial for the home mechanic, the only thing I would add is I probably wouldn't grease the caliper bolts, grease plus vibration during use could cause the bolts to vibrate loose. I'd always use loctite on them instead. But great video!

I had a bike in my garage with no breaks for awhile.. This video has gotten me to to do em xD

The thinner first seal is the dust seal, the thicker second seal is the pressure seal.

I refurbed my front calipers last year - new pistons, seals etc. - and tried filming it. The footage turned out to be a right dog's breakfast, missed quite a bit of it as the phone I was using either ran out of memory or battery, or both.

I second the suggestion of loosening bolts etc. while the caliper(s) are still on the bike. In my case, the calipers are 4 pot so split into 2 halves. If I had taken them off the bike before loosening the joining bolts I would not have been able to undo them. Obviously I could put them back on the forks, but it saves time if you plan ahead and think about how things are going to happen.

I tried to get my pistons out with piston pliers. What a pain that was. Ended up getting a piston extractor kit from Amazon. Best £40 I ever spent. Probably can be used on bearings too...

i am going to be doing this soon to my cbf600. great vid man!

I recommend putting the grease inside the rubber instead of the metal pins. When you put them in, the rubber wipes a lot of it off.


Too much fluid? Your positioning may alter that. I'd go with higher than maximum, set height, the drain excess. (bleed)

[davidbesant]

With the caliper bolts, I prefer to use thread-lock rather than grease (as the manufacturers do). Never had trouble getting them out again, and no worries about the bolts vibrating loose (you really don't want that!).

Fantastic, informative tutorial Sir.. 😎

[KewinKrawczyk]

Thank you for this video! That explains a lot

[markf]

Just bought a caliper rebuild kit from wemoto to do my aging zzr.

When something is extra tight like that pad pin, try to tighten it first before undoing.

[chrisliddle]

Hi watched thanks good intro I have a problem just fitted new seals and dust seals because of binding calipers there still the same now master cylinder could be that does it return fluid and could be this part brake is very keen on the lever

[castrejo]

very good educational video :)
well done

[paulbudford]

Funny enough I serviced my brakes last week. And one of the grub screws was missing too. Only £1.70 plus postage from wemoto.
