Full Motorcycle Brake Rebuild - Master Cylinder and Caliper!

[@MotoTingle]

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-vx3er]

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.

[@spicy110]

Thank you for that very kind comment! 🙂

[@AudreysKitchen]

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.

[@leathleyg5995]

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.

[@spicy110]

Yes that's fine as it comes out the top if it's a strait run.

[@christophermyers242]

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

[@forevercomputing]

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)

[@markf4018]

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

[@spicy110]

Best of luck on the job!

[@markf4018]

@@spicy110all went well. Did the master cylinder- still no joy. Checked out the calipers- which had been “serviced” by a garage. They both had piston seals bursting out of the caliper - and 3 out of 8 pistons seized. 🤦‍♂️ All cleaned and corrosion dremeled (carefully) away. Didn’t even lose a finger when I used my compressor to push the pistons out. I did get some fluid on my screen - but hey - this is bike #3 so - meh - whatever. All rebuilt well and got brake pressure. On the test ride though - the bike decided that it wanted to be triple and not an inline 4. 🤦‍♂️ Still, I have 2 other bikes to ride and I do quite enjoy tinkering with the bikes in the garage. Thx again for your post - gave me confidence to attempt this.

[@roblydiate5453]

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!

[@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!).

[@spicy110]

I did consider it and have done it in the past myself but i did research to see what the facts of the matter are (you can see why from the comments haha) and altho its done by many a properly torqued bolt will not come out or vibrate lose. If you really don't want them to come out wire locking them is the best option.

[@mightybeanstick9872]

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...

[@Zeta368peep]

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

[@chrisliddle2236]

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

[@spicy110]

Are the sliders on the caliper free moving?

[@chrisliddle2236]

Yes new seals new pads

[@johna6968]

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

[@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.

I have a 2009 f650GS BMW . Struggling to get the 4 seals for the front Bremba brakes. I am sure Honda and others have the same piston seal sizes are you able to tell me if so. I am in Cape Town South Africa. Let me know thanks

Gave up and bought a whole new one. Impossible to put back in c clip without riding out the housing.

[@spicy110]

If I remeber right I modified my circlip pliers to fit down in there, old video.

[@bandit12--]

Are the pressure seals non directional on these calipers? I know other ones I've done have a lip and it can be hard to tell without feeling it once its in

[@spicy110]

I check my extra ones and no seems not in this case thankfully. Nor did i see it mentioned in any of the walk thoughts i watched or read.

[@bandit12--]

@@spicy110 Fair enough. Brembo stopped supplying seals at one point because someone fitted the seal the wrong way round and fluid came gushing out. The guy sued brembo because they didn't specifically mention this. Suzuki bandit seals have lipped edges

[@Del197]

That replacement piston on the master cylinder looked plastic ! Was the original plastic or are they both metal .? Difficult to see.!

[@spicy110]

From memory, it was a very light cast metal.

[@Lightspeeders]

i just a complete revesion of the master cylinder of my honda cr but it is still leaking on the end of the lever wtf , everything is new , someone have tips?

[@spicy110]

If you have replaced the piston and seals in the master cylinder and it's leaking and it's defo the right part. I would say the seals are not in the right way or you could even have a crack in the housing. Best get it off the bars, clean it up and find where that leak is coming from.

[@KewinKrawczyk]

Thank you for this video! That explains a lot

[@WorldLogic]

Great video dude

[@colinbourne8345]

If you count to 5 after each pull of the lever as apposed to pulsing the brake will bleed much quicker

[@spicy110]

I had empty lines at that point i didn't want to bleed out the air i wanted to get most of it out the top. There is a small clear inner cover over the MS piston with a very small hole in it, my quick pulsing and tapping to start with dislodged the bubble allowing the line to fill without too much air to need to bleed out after. You will note on the last bleeds i do its a totally different approach more like you mentioned for actual bleeding air out the bottom.

[@bibihamidan8901]

The 'piston' that sits in the master cylinder is getting stuck when i pull the lever and slowly getting push back out, so im am thinking its my spring? Anyone have any ideas? Will be much appreciated.

[@ELI.K55069]

My calipers are seized is this the process to repair it? Sorry if it’s a stupid question I don’t have knowledge on this stuff still new.

[@spicy110]

Yes cleaning it and replacing the seals and or pots would fix that issue most likely.

[@ELI.K55069]

@@spicy110 ok thank you.

[@iamkirankumarkv]

recently i fell from bike to right side. after that break lever doesn't operate properly. often when i apply, lever comes very close to throttle grip. is it because the spring and master cylinder is faulty/broken?

[@spicy110]

Yes or not enough brake fluid in the line or it has air in it. I can't say what one but it will be one of them.

[@iamkirankumarkv]

@@spicy110 okay thank you

[@richardculbertson8027]

I think trk is the in house brand for we Moto and from what I've heard they are OEM or as good as OEM

[@spicy110]

Well they work great so I'm happy haha

[@MVW54]

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.

[@WILLY52368]

I pulled the circlip and the piston wont come out? rusted up. Am I fucked and will I have to buy a new Master Cylinder?

[@spicy110]

If there is rust in there, yer that's going to need a new master cylinder. Don't risk anything with brakes.

[@WILLY52368]

How long does it take for it to build pressure again?

[@spicy110]

depends on the bike and just how it goes. can take quite a while.

[@WILLY52368]

@@spicy110 ok, I cracked the bango so I could service the piston. Put everything back together rear pedal no resistance. Is that normal? So I should continue bleeding and not give up?

[@dougcrabbe6893]

An if you know what hydrologic rubber type and sizes your better off buying them from a hydrologic shop eg a complete brake rebuild only cost me $25AUS and a chainsaw primer fits and locks in great for the dust protection rubber, because I am so sick of the second one says motorbike they try changing you 3 X the price
