very nice tutorial David, just one qestion, can you mix up these pistons, or you need to mark them which are upper, and which are lower one ? Thanks going to rebuild front too for gs500, no big difference as i see
Thanks. These pistons are standard - so long as they are the same size you can interchange them and if they aren't the same size then they won't fit anywhere else. Good luck! Skäl David
Hm, are the primary seals a square profile on the front brakes as well? I’m installing some on a GSF1250 and it looks like one side of the seal is at a slight angle.
Hi there, on my Bandit I've taken the pads out of the front caliper and pumped the lever a few times to get the pistons to move a little, one side are now refusing to push back in despite using a piston spreader.. what have I done wrong?
Sometimes it takes a bit to get the spreader properly placed. If you cleaned everything, then either the seal wasn’t in properly and the piston hooked up on it or the master cylinder is overfilled and there is nowhere for the fluid to go. There isn’t a lot to go wrong because it’s a simple system.
I can't remove the slider, seems to be seized. Got a mk1 Suzuki bandit gsf 600 1999 model with nissin calipers, two on the front and one on the back. The back one I can't seem to remove off the support arm since the bolt is sized. The front ones I can't remove the sliders. Where can I get the sliders rubber grommets and the seals for all the calipers. So confusing which and where to get it from. Also one piston has a slight pliers mark where it was gripped from. The other piston when pushed all the way back in, I apply pressure with the brake, can see a bit of bubbling with brake fluid on the side of the piston before the piston comes out. I'm assuming that means the seals need changing. Also only one piston comes out, unless I hold force it not to move, then the other comes out. None of these have been serviced yet,. Just working out how to do it and what I'll need. What pliers did you use to pull out the pistons ?
Welcome to the world of unserviced calipers! This is why I now replace and upgrade the slider pins etc where I can (preferably to something less rustable like titanium - and it can still bite you if you don't do it often enough. If you've got a sticky piston then there will be a good chance it will need seals, and certainly if fluid is leaking past. For parts start with your Suzuki dealer www.fowlersparts.co.uk/parts/5929079/gsf-600-bandit/front-calipers and you can look up the part numbers to see if you can buy them elsewhere if you find the dealer too pricey. Seals are widely available - here I tend to use Wemoto but there are similar bike factors. There are a number of different piston tools out there - I use something like these www.amazon.co.uk/Sealey-VS1806-Motorcycle-Piston-Removal/dp/B000WZJ7NO If the piston is really stuck, sometimes you need to split the caliper and use a different tool, but sounds like these will be fine. Good luck! Skäl David
Thanks Dave, yes it is. No, I bought them because of you. Dont work when the seals need doing though - the pistons won’t turn which is probably a good indicator of the state of your seals! Skäl. David
Your voice vs intro has a massive volume discrepancy. I do avoid touching the brake pad surface while installing pads. Even going as far as having them material to material and installing so I touch only the backing/mounting area.
Whilst it's important to keep the braking surfaces clean, I don't go overboard about it as they will get contaminated with oil while you are riding, but that level of low contamination burns off as soon as the disks heat.
@@forevercomputing If you've ever ridden in the rain then your bike will have been splashed with diluted diesel and other vehicle fuels and oils. Since the brakes are low down they get much of it. It's not a high level of contamination but then assuming your hands remain clean whilst working on your bike, which they should, neither will be transfer from your hands. Being careful is never a bad thing, but having a balanced view is important.
@@forevercomputing I've installed a lot of brake pads onto bikes, and not had any issues, but there will always be the exceptional times when things don't go right for one reason or another.
A cracking how to fella, nicely filmed and demonstrated.
Cheers GT, always appreciated. Hope you are keeping well fella. Skäl David
Brilliant video and very informative.
Cheers Ivan, always appreciated and I hope you are keeping well buddy. Skäl David
Excellent video David, very well explained, keep up the fantastic work 👍👍👍
Thanks Colin, your support is always appreciated! Skäl David
Another great video David!!
I hope you have a great weekend!!
Cheers Garry and I hope the same for you. Shaping up to be a hot one here. Skäl David
Hey David a perfect demonstration brother ! 👍☮❤
Thanks brother, hope you are having fun in that garden! Skäl. David

It depends. Most will have a square profile, some are angled in which case the highest side is normally inwards.

@@MotoMirius thanks mate, removing the top of the master cylinder got them moving.. All fixed. Love your vids
Great news. Well done on getting it fixed 👍

Excellent tutorial Dave, must be so satisfying 👍🏻 I see you got the pliers similar to mine or did you have them before? Enjoy your weekend.

@@MotoMirius Hmm, not in my experience. Always good to be careful though.

@@MotoMirius I have, and I have experienced poorly installed brake pads (my fuck up)
