Step by Step - how to strip and rebuild a rear master cylinder

[@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.

I want to say thank you for uploading this video....without this I would not know how to disassembly rear master cylinder for my 1995 zx6r..

[@shinseikatsu2014]

Helped me to rebuild a clogged rear master cylinder on an old YZ250. Works great now, Thank you!

[@anpatron4439]

Thanks for the nice vid. Probably, no' need to remove the clevis part, as long as the push rod is long enough to allow removal of that circlip. Saves adjustment on the bike when putting it back toghether...

[@2wilboundaround239]

Or just mark it with a sharpie.. I pulled mine apart and when I pulled the push rod out after removing the snap ring and there was no piston inside with the rubber o rings or whatever.

[@nikchristides4895]

Excellent work mate, 2 out of 2 videos are just perfect. Thank you

[@jayminasi6073]

the first step when making a avideo is to provide a good light source so the viewer can see the details of your job. your desk area is darkish.

[@yopappy6599]

Like getting instructions from the little turtle in finding nemo.

[@TheHambletonbiker]

Great video, I always wondered how a rear master cylinder worked. Another one of life's mysteries solved ;)

Ha Ha, I have no doubt it will start, I got a massive hammer if necessary ;)

[@richardmiller3781]

Great video helped me save a bundle.

[@GTsGarage]

Fantastic Richard, thank you for leaving feedback, glad it helped Sir.

[@josenigaglioni4877]

Thanks. Great help.

[@markwilkinson9263]

Thanks, answered my questions.😅

[@bloodyhell451]

Have a good one GTs ! Make sure you show us the beast next time ;-)

[@Majorvideonut2]

I would measure the distance from the yoke hole to the first MC bolt hole so you can line it back up for easy install.

[@TheThoover]

Good video - thanks

[@keithmartland6463]

On mine had to pull the rubber down to get at the nut, and that was well and truely stuck, knacked the end of the tread trying to hold it while undoing the nut, the rubber in the meantime was off the nut, and still haven't got it off, if i us heat will end up mealting the rubber, so looking at your film it looks easy but in real life nothing is easy

[@ANDY5]

Merry Christmas mate :)

[@GTsGarage]

+Andy's Motorcycle Obsessions Happy Holidays Andy, hope you are all well over there, we are just getting used to the weather being mild over here... just goes to show the weather men just make it up, we were supposed to have the most snow over Christmas since records began... hope i haven't just jinxed it.

[@azdesertdog]

Nice! Put it in my favorites.

[@GTsGarage]

+azdesertdog Thank you, appreciated.

[@lubymaness6165]

Wow.. thanks you saved me at least 200 dollars.

[@haloreach107able]

Which ways do the new seals go ?

[@zepplinmurphy1984]

Thanks for sharing! Helped a bunch!!

[@longboardenespanol]

The plunger on the ktm 1090 adventure r did not pop off as yours did after the washer removal... The spring is still inside

[@rjauto7215]

gob well done good man . and you have a great xmas fella

[@GTsGarage]

+Roy Webb You to Roy, take it easy fella.

[@victor.chirita20410]

Thank you, sir!

[@goozlo]

You skipped the most important part.....the orientation of the new rubber seals on the piston......................

[@GTsGarage]

Cheers for the clarification fella, hopefully now pinned, other viewers will realise the importance, prior to disassembly.

[@Leon-co2rr]

[@TOCA550331]

hay alguna forma de ajustar el recorrido dentro del cilindro maestro? cuanto es lo que debe recorrer para que no frene inmediatamente? gracias

[@ineedahatnow]

thanks mate.

[@jeffveraart2695]

Thanks for that.

[@maddmavic]

How do i know of its my master or something else causing the issue. The caliper seems fine but even after bleed the brake it dont grab and the pedal goes all way down super easy no leakes any where. Would that be the line kr master

[@GTsGarage]

Not sure, that sounds like there is still air in the line somewhere. Have you cracked open the banjo bolt to see if theres air trapped in the highest part f the caliper.

[@Iseekoutthetrails]

good info

[@GTsGarage]

+1down4up Cheers fella, appreciated.

[@umiketu8e]

Great video, exactly what I needed. I have 2 questions if you can help me. which way seal goes on to the piston. seal has 2 different edges single and dual - hopefully I am explaining this well. second question: the main bold has at the end a hollow pin through which prevents me from taking the top off (I think you called it clevit) - any idea how I can remove clevit

[@GTsGarage]

Hi Michal, whats the bike Sir?

[@umiketu8e]

+GTs Garage it's a lovely Honda cb1300 2003 and the rear brake is very soft, I can't lock rear wheel no matter how hard I stamp on it. I bled it and there is no air. I am assuming master cylinder is not holding the pressure so want to change seals as you have shown but am stuck with top part. Thanks

[@GTsGarage]

Hi Michal, take a look at the following website, it gives you a break down of the rear master cylinder. www.lingshondaparts.com/honda_motorcycle_parts_selection_pfk.php?block_01=13MEJ3E1&block_02=F__1200&block_03=1369&block_04=xx&block_05=hmc if it isnt exactly what you are seeing, then go to the home page and re pick your version of the CB1300 listed. The detail should show you how the component is put together, come back to me if still no help

[@umiketu8e]

+GTs Garage thanks. This is perfect. Actually it does not show that push rod 12 has a pin through at the bottom, so I guess I can just get rid of one I have and replace it with split pin. Thanks very much and all the best

[@bloodbatteries4797]

Hi I have a question....I need a new rear master cylinder on my bike 97 custom wide glide .....can I just put a new master cylinder on an be done or do I have to put a new gear shifter on with it.... that's what my mecanic told me....is he trying to hustle me...

[@justanormalguy1539]

I hava a que we are building a atv wih a 250cc engine and I need two brakes on the front but I'm not getting enough displacement from the front. master cylinder thn which master cylinder should I use ??

[@GTsGarage]

Not sure to be honest, have you found any ATV specific boards?

[@chad2139]

Are there any tricks to reinstalling the right angle tube (the one you didn't remove in the video)? I've been wrestling this sob for about and hour, afraid I'm gonna tear it up...

[@GTsGarage]

Hi, apologies for the late reply, I found air was the biggest problem, I had to use my thumb to make a vacuum and draw the fluid through, only when the fluid is at the banjo connection did I attach the brake hose, then bleed as normal

[@iforgothisname2564]

I'm having this problem with the rear brakes. When you push down it does its thing but you take your foot off the pads stay on the disc and the peg also comes back up. I'm not sure if it is the master cylinder. What do you think it is??

[@GTsGarage]

Have you taken the rear brake off, and visually checked for movement?

[@GTsGarage]

Did you manage to resolve it...

[@dheybay9274]

it would been better if you do that outside for better view. your background is keyboard etc that makes it hard to see some parts of the vid.

[@stripfix1979]

Just a quick one mate, what do you use in the ultrasonic cleaner? Also have a great xmas... Glenn sussex

[@GTsGarage]

+Glenn Moore I just use washing up liquid and a bit of bleach but only used on caliper pots. Well worth doing some research on the net for other cleaning recipes when other items.

[@srikanthregatti2401]

What is the diameter of master cylinder in pulsar 220cc

[@GTsGarage]

Sorry i don't have that information, but google is bound to provide something.

[@felixthecat1251]

NUTS not bolts !!!!!!!!!

[@amanchheda6302]

what was its bore diameter? ?

[@GTsGarage]

not sure to be honest fella, sorry

[@edwardsteele4022]

whatbate the implications of using petrol..ive just put mine in petrol to soak... without watching this video first!!!!!

[@devillthappa7645]

my pump oil leaking

[@GTsGarage]

Its quite easy to get an air block in these when putting them back together. You can remove that by capping the end with your thump and quickly releasing it, until the oil flows, then connect to the hose to the rear brake and bleed as normal. If you have an air block in the pumpg can cause additional pressure to be applied internally casing the seal to pop and and force liquid out, Good luck

[@jayminasi6073]

very dark there. can't make out detail.

[@ediedide]

to much light , next time reduce light a little

[@sk_ram_007_]

S K RAM

[@charlessibille2768]

No mention of how the rebuild is done, all I saw was taking it apart and put back together. Not really helpful! Anyone can do that. No explanation of why it fails. Obviously I should make a video, couldn't be any less informative.

[@jayminasi6073]

i can't understand you too good, rats
