great video, but i noticed two things in this video. 1.) you cleaned the rebuilt caliper with brake cleaner right where the new rubber seals are going. wont that dry them up and need another rebuild? 2.) you mentioned the caliper bolts are a one-time use and need to be replaced everytime the calipers come off. I've never seen that in any service manual, and racers sure dont replace their caliper bolts every weekend at the track when they're swapping tires 1-2 times a weekend.
The beauty of brake cleaner it that it evaporates. You shouldn't spray the seals directly, but the surface of where they are going is fine. As for the caliper bolts, "by the book" they are supposed to be replaced on older units. It's something I have just continued to live by. They don't require replacement on newer models as they don't stretch like they used to.
right, but the cleaner will still got on the rubber seals and dry them out. I clean mine regularly, but use 50/50 Simple Green & Water. define older units, as that sportbike in the video is newer than many of the race bikes out there that are reusing caliper bolts that are taken off 2-3 times a weekend.
@@jimmcconville624 The cleaner drys within seconds. By the time you put the rubber seals in, the cleaner has evaporated. Plus, you should wipe out the caliper with a rag anyways before you put the seals in.
Very clear video but that is a pretty new bike with everything not worn or gunked up with crap, I used this method and quickly discovered I had a couple sticky pistons. The air line blew out the good pistons and once one piston is out there is no air pressure to blow the sticky ones. I will pump them out with the old fluid next time, also splitting the caliper makes fitting new seals a lot easier and a good opportunity to give them a thorough clean.
They, do, the three Allen or Hexagon bolts on the inside of the caliper hold the two sides together, there is no way to machine out the pistons and connecting. Chambers if it was a solid casting.
With the calipers split you can blow air to get pistons out... HOWEVER, you need to use really good eye protection and wrap with a towel to keep the pistons from becoming bullets. All Balls Racing has rebuild kits.
this guy is the most amazing person. just listen to what he said. ow these pistons look like they are in great condition. but we are doing this just to show you... that means this guy took time out of his day. to rebuild something that didn't need rebuilding. but he did it anyway... FOR US what a fucking legend guy!! Thanks John!!!!
Thanks for this simple video. Unfortunately for me at this time that im typing this, that one time use flange bolt isn’t in stock at all Honda dealers across North America. It’s back ordered until October.
Maaan! You're amazing! Your expertise, your patience, you can tell by your body language and facial expressions that you really DO want to help the motorcycle community! God bless you old man! (I mean that in the most respectful way possible.)
Personally I have always reused the bolts. any reason why they say to replace them? I dont really see why you would need to. They dont get loose. al least never have for me, and I have multiple stunt bikes. Brakes get worked on all the time.
Yeah great informative video I don't know where the information about replacing the bloody caliper bolts that they are one time use only as ridiculous should say that about the crush washer on the brake line. As a track racer I take my break calipers on and off a dozen times in a weekend same bolts!
I thought the same as you, as an ex racer, yes these bolts are on and off very regularly. Apparently, some of the newer bikes use crush bolts which like a nylock nuts have a single time use. As racers we would not use these type of bolts, it'll cost us a fortune! if in doubt lockwire is the answer, I would probably not bother too much on short circuits but for the TT course it as an absulute must, it'll shake your fillings out and easily loosen anything not lockwired or siliconed up.
what makes that caliper bolt one time use? i have reuse my caliper bolt original from the factory and no problem. before re use them i brushed the thread by wire brush and use some medium strengh threadlocker..
The Honda Factory Service Manual has them as one time use. So that is what we follow for our videos. Most people reuse them and have no issues, but we try to do the videos per manufacturer spec.
Is there a particular process to follow filling the calipers up with fluid and bleeding? I’ve performed the standard brake bleeding and the pistons won’t press against the pads to the discs. This is a 98 Honda CBR 600 F3. Having a heck of a setback. 😅
@Conor Immanuel Yeah their documentaries on calliper rebuilds are exemplary. I love Flixzone for brake refurbishment. If only other people knew about Flixzone. That's great, new improved Flixzone. For all your bike braking needs.
There’s a seal in between the two caliper halves that should to be replaced also. They aren’t monoblocks. They’re meant to be split during the rebuild. Way to half ass it.
Wow, Partzilla really produced this? If you're going to go through this process, why not unbolt the two halves and replace the o-ring that seals the passage between them? This o-ring is also sometimes the cause of leaks. A good seal kit will come with that o-ring. Besides, removing and reinstalling the pistons is MUCH easier when the halves are open faced. This video probably skipped 10 or 20 minutes of misery trying to work those pistons out of that narrow gap. In real life, pistons seldom conveniently pop out 2 at a time. One will pop out and leave no air seal to pop the next one out. With it open faced, you can pop one out, clamp it slightly inserted to create an air seal, then pop the another one out, almost as fast as you're reading this sentence. And I can't believe you grabbed that piston with pliers. "If you grab it with a pair of pliers, make sure you're all the way up..." NO! Don't use pliers at!
I thought that to. It made me go look at the caliper again I must say there's no evident line where they'd split . His diagram says otherwise so I don't know mine do but diff bike
You can get them all out just with the air ... you need a piece of metal centered between the halves that's just the right thickness to stop any piston coming all the way out. Then split the calipers and they just wriggle right out with fingers. Also split calipers and they are way easier to clean the seal grooves in the bore. Dried brake fluid there will mean the seals are too tight such that all pistons don't move at the same rate.
I have question and i dont know whats wrong with my quad it goes on its own if i dont hold the clutch and i dont press the gas at all and i cheaked the cooling fan and it works

You can use them as many times as you want, as long as the thread itself is not damaged. The only thing you need to replace every time are crush washers. I haven't seen any bike where in service manual it says that some bolts are one time use only. Typical wallet reaching talk.
Service Manual says to ... ALOC bolts ... but feel free to use common sense ... plenty of people reuse. www.vfrdiscussion.com/index.php?/forums/topic/70138-brake-caliper-mounting-bolt-replace-with-new-ones-or-not/
Thx to good Vid. When the piston is inserted. I heard you should wear silicone grease. It is said that the piston and seal are stuck due to high temperature, which causes brake function problem. Is it really enough to apply brake fluid?
I have a question....I have a triumph sprint st and I have bled the brakes a few times but they still feel spongy...is this a piston and seals problem?
hey ive got a cbr600fa 2011 abs model bike my middle piston on the brake caliper is stuck.im guna try u process but how do i bleed the brakes due to it having to bleed nipples thanks in advance
Partzilla got all the parts needed now so will be doing ur method come saturday was just unsure because of it having 2 bleed nipples per caliper and of coarse it being abs.cant thankyou enough
They aren't readily available. Service manual has the piston diameters. Or you could just order them from here. www.partzilla.com/catalog/honda/motorcycle/2005/cbr600rr-a/front-brake-caliper-05
