Safety is a top tier priority on your vintage motorcycle. Our Honda CB175 / CB200 / CB350 / CB360 / CB450 / CB500 / CB550 / CB750 series of bikes do not have the best brakes to begin with, as it goes with any old bike, and when you throw the age of these components into the mix you have a disaster waiting to happen. Safety is one side of our core value triangle over here at Common Motor Collective and should be on yours too. Being that we make everything you need to get your hydraulic brake system in tip top shape we thought it was time we gave you a full guide on how to put it all together. This video is Part 1 of a 2 part series where we show you how to disassemble, inspect, rebuild, replace and properly install all of the pieces in your hydraulic brake system. Since every bike is different, In part 1 Brenden will show you how to disassemble the brake system and how to look for signs of what you can save, what you may need to rebuild and what definitely needs replacing on that Cafe Racer or Scrambler build of yours.

Just an idea. Instead of applying grease to the edge of the pads, apply it to the inner part of the caliper body. In that way any excess grease is pushed to the back when you insert the pad instead of getting caught at the edge of the opening and potentially getting on the pad material. I would also use it more sparingly... just an idea. Love your vids tho :)
Excellent advice.
Thank you for this! It happens to be the next piece on my '73 CB350F. You guys rock!
Thank you this is exactly what I needed. 1st rebuild.
Thanks Brendan, great video. Helped me do my 500 / 4
Saw this after I took my calliper off. Used your hardline in the master cylinder technique and it worked to push the pad and piston out AND it helped me diagnose and fix my bleeder screw. Officially owe you one! 🍻
Did ruin my wife’s baking tray though. Oops.
Thanks for the video I just removed my piston today using my bycle pump - same principle and fast - saw it also on youtube - just a tip!
Just bought a 1975 360. 1100 original miles, immaculate cosmetic condition, cant wait to get her running strong. So happy to find such a valuable resource! I'll be using your store ;)
What fun!! I have an 82 900cb. I get people hollering at me every time I stop at a light downtown. Enjoy your bike and be careful.
Any old bike that has been parked for years will need everything. Especially relating to brakes and fuel (for starters). Hope to goodness there was no fuel in the carb float bowls or the cylinder heads. A nightmare is what it is. Funny why people it's awesome or exciting to get an ancient car or bike that has been sitting for years. A horrific mess is what it is.
@@HorsepowerHouse I've put a few thousand miles on it (mainly country roads) and really haven't had any problems! Replaced the brakes and tuned the carbs and it's been great!
Great video!
A flare wrench would have been the better choice over vice grips that can damage, mare, or destroy the nut. Love the video and channel! Keep up the good work and ride on!
I am restoring a 550k right now and for the first time in my life i decided to get all the right tools,i have labeled every single bolt, washer,cable,tie strap , you name it, i have put it in a baggy with a tag attached with tape (major pain to do) and i have sprayed every single fastener with Kroil oil,i got down to the bare frame tonight without marring, breaking or damaging a single component and I'm having a great time,i wonder why i put myself thru so much misery my whole life until now,lol
Good morning. Firstly, I would like to thank you for your superb videos.
They are absolutely invaluable.
I have a Honda cj250t 1977.
What is the best bike for a comparison?
Nobody really has any dedicated video, and information is hard to come by.
I also live in England, which makes things even more complicated.
All the best, David.
I'm waiting for the video on drum brake. PS. I love the old footage you included in this one
Please, def need them for my '74 CB360
Do I need to use a Junction block? My upper soft line reaches my hard line, without on, on the CB450K4 I'm rebuilding. Thanks for the video (and the rebuild kit!)
Hi. I want to swap my caliper cause i don’t have parts what caliper can fit the nighthawk 450 ? Thank you
i'm in the middle of doing this job and just realized that i don't have new crush washers for the banjo bolts. argh! might i get lucky with reusing the old ones?
Would you be able to replace the old lines with the box for just one line, does that work?
Ok, so I dropped the piston in the caliper body and attempted to push it down. The piston stopped and refused to go any further. I’ve lubed with brake fluid and stretched the seal as per the video, but it refuses to move…in either direction. What now? Thoughts?
Hello would this be the same caliper as a 1976 honda 400 four. Any help much appreciated
My mistake - I bought a new caliper kit on e-Bay - that was my mistake - should have got it from you folks (like all my other parts). The piston it came with was open on one end - looks strange, but OK. My question is which end goes into the caliper? The open end or the closed end? If the open end goes in, it will need a lot more brake fluid and is much harder to bleed - the open inside of the piston traps a lot of air. But if the open end goes out to contact the brake pad, it doesn't look solid enough to stand up over time. The closed end is a smooth surface, much like the end you show pointing out to contact the brake pad, like you show it in this video - so I'm confused. Brenden - please help. Thanks.
good video, cause includes support from a builded up experience... errors one could commit like a noobie
just finished rebuilding my 79 GS750's brake system! just my luck this video came out today lol
That's how it always works,not a religious man but when it comes to Murphys law i am a devoted follower.
Does all of this apply to '80 CB650/Cb650C?
What is the easiest way to remove the piston seal from inside the caliper?
Just did my frint brakes on a cb900 last night before i saw this vid, would have been helpful lol
My CB450 doesn't have a junction block, is that a problem?
great
I'm doing this to my bike again. After a couple years the grease i used was hard and waxy. I'm thinking about going in dry and see what happens... Any thoughts??
I'm also suffering heave grease on my brake pads so I'll try a very light silicone spray onto a rag.
I am doing a 650 night hawk 1982
Couldnt you put jb weld into those piston pits?
In a pinch yes you could fill them and sand them completely smooth but it would be difficult to do perfectly and you could end up with another leak. Usually if you take into account the time to do that work and new piston saves you money.
I just use a tyre inflater with an air bed adapter and blow the piston out, pops out nicely.
Could you please elaborate on how you did this? I need to remove my piston (again) and would rather not go through the entire process of reinstalling and bleeding only to take it out again. Thanks.
@@vacuous415 This is purely to push the piston out,, and the system will still need to be bled,, the bleed nipple is left in and an air bed adapter with an ‘ O ‘ ring around the end is pushed into the brake line connection, switch the compressor on and the piston will pop out,,I suppose you could also leave the break pipe on and blow through the bleed nipple connection as well.👍
@@thetruth156real3 I know this is old comment but it would be good to point out to have it facing against a block of wood or if the 2 haves are still joined by the long bolts put a piece of thin wood in between them,i have done this many times and when that piston breaks free (specially on a car caliper) it will startle you good and if a finger is in the way somewhere it will be a little painful,lol
I was pushing one out, years ago out of a T Bird with a really big air compressor,when it came out my neighbor came over thinking he had heard a gunshot, ha ha ha ha
@@dntlss Good point well made! You do need to be careful.👍
What about a durable paint for the caliper?
paint and brake fluid are not friends. I stripped and polished my calipers. They come up real nice.

Michael Scott " That's what she said"
Why not just use compressed air to blow out the piston. Waaaayyyy faster
After watching half a dozen of your videos, one thing is very apparent ... you love grease.
Did you really just use vice grips on it???
My thought exactly!! That is NOT a 'pro tip'... more like a backyard hack tip. Use a flare nut wrench.... grips the nut on 5 sides.
Most people aren’t going to have a flare nut wrench doing this type of work for the first time and we see it all the time where they’ll destroy the nut. Good quality vise grips will grip onto the nut and be able to break it free 99% of the time without damage from our experience. We try to do all of our repair jobs with tools most guys would have at home.
Common Motor Collective I remove them with regular open end wrench. No issues so far and some of them were really cruddy.
Jut watched the first few minutes this looks a bit, BAD!
