Thanks Musa, Glad you like them, appreciate your comment

Just came across your Chanel mate there’s one thing you forgot to do when you stripped down the calliper you forgot to take out the dust seal ring that fits where the piston goes you painted it the dust seal goes around it then you tap it back in place when you’ve put the piston In good vid mate

hey man keep up the great work I'm about to start restoring a 1977 KZ650 that belonged to my father and this channel has been absolutely amazing

[@TheAmateurBikeBuilder]

Thanks Chris, hope it goes well and i am glad this is of help, i am learning as i go on this one, it is a challenge but will be worth it to see it back on the road, let me know how your resto goes

[@locustbay7594]

Looking good

[@TheAmateurBikeBuilder]

Thanks, always nice to put back together, will be another job ticked off the list

[@MichaelDavies-iq3yd]

The 'O' rings go inside, not outside the bracket tube, so the bolts slide in a sealed & greased tube. Check the position during disassembly. The O rings are difficult to see inside the bracket tube as they sit in a groove. The dust seals alone go the outside. The presented sequence will work for a while, but the dust seal is doing the work of them misplaced O rings, which do nothing.

Thanks appreciate the advice

I'm just about to service the clutch master cylinder on my 89 ZX10 (very similar) The last muppet to mess with the bike, put parts 12 and 13 the wrong way around. I'm surprised it work at all.

[@TheAmateurBikeBuilder]

Thanks, love your KZbin name, i know how you feel, especially if you watch the fun i have had sorting my ST1100, previous owner didnt have a clue

[@journeyquest1]

Probably better off painting after rebuild. Brake fluid will strip paint.

[@TheAmateurBikeBuilder]

Cheers, appreciate you comment

[@martinquick6091]

The spacers go on the outside of the caliper , under the slide bolt rear nut in a recess , not inside as you show . . Brakes spongy with the spacer inside

Great channel and I've watched every episode as I'm currently restoring a 1978 Z650 Custom. Where do you get all of your brake parts from incl #4 in particular as according to my drawings it's no longer available through wemoto :-( Any guidance/tips gratefully appreciated. :-)

[@TheAmateurBikeBuilder]

Glad you like them! #4 is rare than (well you know what i mean) not seen any about, if you have one, you might want to do what i did and make one, i have one so i could copy it , alternatives are you can try Z-power or ask on one of the Z650 forums

[@SnapdWrench]

Hello and thank you for the video! I'm having issues with my brakes however. My Bracket willy nilly slides around on the 2 bolts, and my brake pad doesn't stay put and falls out of the bracket. I don't think i can use my brakes like this. any info would be helpful.

[@TheAmateurBikeBuilder]

Hi, i hope this will help www.cmsnl.com/kawasaki-kz650b1-1977-usa-canadamph-kph_model14582/partslist/64358.html#.YuV9JnbMJPY you can see all the parts, my issue i had was part no 4, sadly they are no longer available so i made my own and seemed to work as i only had 1

[@SnapdWrench]

@@TheAmateurBikeBuilder How were you able to make it? isnt it made of rubber? If i stack some washers that could work right.

[@TheAmateurBikeBuilder]

@@SnapdWrench i had some steel bar and as i had the other one cut it to size and drilled a hole through it, worked a treat, could try washers, maybe weld them and file to size

[@SnapdWrench]

@@TheAmateurBikeBuilder 6 washers stacked were able to perfectly keep it in place!

[@albertsteward7460]

@@TheAmateurBikeBuilder I don't suppose you have those dimensions to those No.4 'plugs' to hand? I'm rebuilding a caliper and sadly both are missing. I've searched online but not been able to find any info beyond the original part number.

[@DeeBeeStudioSabah]

I have a 1977 B1 KZ650 as well that need to change the piston. I can't find the piston for B1. I saw they have for C and D model in ebay. Are they the same?
