Ms. Cooper: I have now completed a full rebuild of my two front calipers, including freeing the two sections of each of the calipers, which were solidly corroded together, so they can move freely. Your video, which shows you pulling one section loose from the other, was absolutely key to my understanding that they should move freely and be greased as part of the overall process. Many thanks for one of the best and most useful SV 650 videos out there.

Also, I got the hand vacuum pump your friend used in another video and it really helped as well for getting bleed started.

Fantastic video!! The caliper is exactly the same as I have on my bike. And when I was just swapping pads, today, I noticed one of the dust seals, protruding a bit...and I thought, “oh great...another issue I’m not prepared to handle, myself!”....then I watched your vid, and realized how easily I can refurbish the entire caliper, with all new seals. Thank you very much!

Tamsen: You made this process seem very straightforward with a clear and easy to follow video. The bike community needs to encourage more people like to get their own bike. Take care.

What a lovely comment, thank you. I am pleased you enjoyed it and hope you like the new upcoming videos too.

Congratulations on a great tutorial! I still lubricate with special grease the pins working in the rubber bands. This type of clamp likes grease in this place. NOT copper grease! Well my favorite cleaning tool - a toothbrush. Perfect for cleaning brake calipers.

iv found after using copper slip on the sliding pins it causes stiction. the best stuff is silicone greas as it slides better and u don't need alot and doesn't cause rubber to swell. also brilow pad but like the one on the back of a kitchen sponge cleans out the oil seal recess out good and gets rid of corosion. but you did a good job of explaining how to do it and any one stuck will not have a problem learning what to do. 👍

The copper grease has it place on the back of the braking pads and only there. Ceramic grease is even more better. I have already installed pads with no grease on it, never had any funny noise or grinding. Copper grease should harden with time stick and pull pads inside when brake pistons retract. Cheers

I have one question though. I changed the pads on my SV650 (K7) and the brake pistons won't slide back in. Apparently they are stuck. Now I need to take them out. Would you recommend bleeding out the system before doing that. If so, I guess this would also mean getting the pistons out is even harder. But if I don't bleed the system I run the risk of having brake fluid all over the place.

@TamsenCooper

You can use a piece of wood between the pistons once the brake pads are removed and use the pressure of brake fluid to push the pistons out as far as you dare. I agree to completely remove them I would drain the brake fluid first as it is horrible stuff to spill everywhere, but if you use the brakes hydraulic system to push the pistons out, it may make removing them easier. Be careful not to scratch the pistons when you clean them. It sounds like it could do with a decent maintenance, could you imagine what it would be like if the pistons stuck when you needed your brakes... eeek! Good luck and let me know how you get on.

Same brakes as my 2000 Kawasaki ZR7, which I'm currently working on. Your video is a great tutotial. Thanks.

only two suggestions. brake pads can be washed also with water and brush. and for assembling caliper pistons can be used a silicon grease. This can prevent retraction of pistons that cause a lever's free play.

Question: It looks easy to remove the part of the front caliper that releases the seals so that they can be replaced. But, on mind that part seems completely stuck and immovable. Did you remove any kind of pin or bolt or washer to enable removal? Did they really just pull off that easily as shown in the video? btw: absolutely great video. Well narrated and thorough.

Brilliant video.I would add when i remove the caliper off the bike i remove the pads then boil the complete caliper in water and soap power on the gas ring in my garage. This softens all the muck and gung.I can remove the deposits with a piece of thick copper wire.

So I’ve followed these steps but I can’t seem to get the pin out to remove the pads any suggestions ???

you need a parts washer girl !!! save you a lot off mess and time... but, saying that, any one who does their own maintenance on brake calipers with a tooth brush on the kitchen table, is worthy off at least ten minutes off my dreams !! ohhhhh the memories. well done. most blokes I no wouldn't even no how to get the pads out...( kinda worrying )

Hey Tamsen. Brilliant video. Need to do all the callipers on my K3 650. I was just wondering, did you drain all of the fluid from the system so it was empty before removing callipers? If so was it easy to re fill the brake fluid once they were back on? Thanks

@TWIRKNOLOVE

dont drain it all - it will be harder to bleed once you're ready to throw it all back on. keep the res. cap on and let the brake lines hang - maybe put them in bags so fluid doesn't get on the floor. once you're done with your rebuild and button it all up, bleed the system with new fluid until the new clear fluid comes out the calipers with no bubbles.

Good job bro

Can you do a video on the rear master cylinder on what way the rubber seals go, how it all fits in. Just installed new beaded break lines and I may have re built the master cylinder wrong. By putting the seals the wrong way around. Thanks

Ah I see the problem, now the cables are disconnected you have no hydraulic press to force the pistons out.

Saw this done on another video, but if you have access to an air gun, you can apply air where the banjo bolt attaches to the caliper and this should raise the piston/s out either all the way or almost all the way out by using a block such a piece of wood, etc. Then, for the final removal, use pliers padded with a piece of cloth being careful not scratch the pistons.

@The_Touring_Jedi

You can get pistons out with pliers, you take some old kitchen rag,put at first couple of layers of alufoil and aplying pliers on the edges slowly turning clockweise and oposite pull the pistons out. I have done so that the pistons have no damage. Anyway if you have damaged pistons on the edge near the contact to brake pads, means outside surface , dont worry about it. Take sand paper and water 1200 and make it nice. Brake pistons never retract inside until they slam the back wall of caliper. Even if you put new pads there is almost half of an inch( ok maybe little bit less)piston sticking outside of caliper. If piston get damaged beyond that point, you better buy new ones.

Copper grease 'is' a high temp grease, by a big tub, it even tells you it's for use for many things including brakes. It is partly to avoid brake squeal, but it is also used to prevent corrosion, I've always used it to lube brakes and many moving parts and bolts that don't need locktight, as have the college I trained at and all the garages I learned and worked at too. Don't believe everything you read or hear on KZread or anywhere else on the internet, but it's down to you to decide what to believe and what not to, do what you feel is right and what works or you.

sv650's have a common problem with the front brake master cylinder piston going sticky.. giving the impression of a binding caliper ! both my wheels must rotate freely without any resistance. if the front wheel doesn't then it's usually the master that's the cause .... to fix this quickly without removing anything, carefully apply RED RUBBER GREASE with a blunt cocktail stick underneath the master cylinder piston gator. then a "low" pressure air line is used to blow the grease into and around the piston inside... DO NOT use any other form of lubrication, ie wd40, oil of any discrption, brake cleaner etc. apart from brake fluid (and that applies to brake calipers ) .... of course the correct way would be to remove and strip the complete component and rebuild, then periodically do the above .. my sv is used all year round every day, rain or shine and is not garaged or covered up .. I find I need to do the above once a year . A mate of mine had his sv brakes stuck on as he pulled up at traffic lights .. cause was master cylinder piston stuck.... Both your wheels must turn freely !

How to remove caliper is not shown

Looks like this bike didn’t had his regulair maintenance for sure.

Brake fluid is a corrosive so why do people use it as a lubricant when reassembling their calipers it attacks the rubber and the aluminum as it goes through heat cycles and its hygroscopic nature is some part of the reason you get a pile of white crud behind the seals. Best practice is to put replacement seals in dry and before the piston is reinserted, wet the tip of one finger with power steering fluid and wipe the surface of the seals this should leave a trace amount on the rubber and nowhere else. Any excess PSF should be wiped away with a clean cloth/ tissue this will still leave a trace amount on the seal. Before insertion of the piston, the piston wall can also be wiped with a little PSF but only the wall and excess will be removed as the piston is reinserted. Again this should be removed with a clean cloth before any further steps. PSF contains conditioners for rubber seals, its main use is as a hydraulic fluid but it also an oil so provides valuable lubrication for the pistons in the caliper helping prevent friction and stiction meaning more efficient braking and then release. Best regards HarryB

I guess most people do it because its whats stated in any manual when overhauling the calipers

Again and again the same errors in brakes rebuilding. You shouldn't use copper grease in the boots rubber because they absorb the grease and get useless. Always use silicone grease please. Some seals have side, be careful. And probably a good idea to use ceramic grease...

thanx for the video, but there is no guide to bleed the brake, so that leaves one clueless on what he has to do next :(

Hey, pleased you liked the video, I have done videos on brake bleeding, even managing it one handed due to a broken shoulder! Here is a link to that video- kzread.info/dash/bejne/e35kspespaWfms4.html I have a playlist of maintenance videos, I hope they are helpful. Thanks for watching.

jesus, this bike is so dirty and fucked up. all rusty... what the hell do you do with your bike... Like copper paste on the rubber parts, just use normal grease. works the same and helps the rubbers

This bike is a replacement bike after a car wrote off my last one with me on it. I bought it from someone who kept it outside and remember, it is a 14 year old bike! I guess that is the point of maintenance videos, if it was perfect to begin with then the job wouldn't have needed doing! I like working my way around the bike and restoring it as best as I can. I think grease on parts is essential, and any is better than none, but the reading I have done about the different properties, and speaking to people with far more experience than me (motorbike mechanic for 25+ years says to use it, so I did!) means that there are subtle differences between various products which are designed to act in different ways depending on the situation. Thanks for the comments, I hope you will watch future videos too.

sv650's have a common problem with the front brake master cylinder piston going sticky.. giving the impression of a binding caliper ! both my wheels must rotate freely without any resistance. if the front wheel doesn't then it's usually the master that's the cause .... to fix this quickly without removing anything, carefully apply RED RUBBER GREASE with a blunt cocktail stick underneath the master cylinder piston gator. then a "low" pressure air line is used to blow the grease into and around the piston inside... DO NOT use any other form of lubrication, ie wd40, oil of any discrption, brake cleaner etc. apart from brake fluid (and that applies to brake calipers ) .... of course the correct way would be to remove and strip the complete component and rebuild, then periodically do the above .. my sv is used all year round every day, rain or shine and is not garaged or covered up .. I find I need to do the above once a year . A mate of mine had his sv brakes stuck on as he pulled up at traffic lights .. cause was master cylinder piston stuck.... Both your wheels must turn freely !
