XT600 XT600e front brake review and rebuild; check the caliper and bleed the system. Regular checks and rebuild will keep your brakes in top form and prevent the pads sticking.
Quick question. I watched your video about the rear brake fluid change. I noticed that there you pressed the rubber diaphragm in when it was in the cylinder, but here you did not? Did I miss it or? Thanks for the help, keep the videos coming some find them invaluable :)
Great question and a good eye. As the brake pads wear, they push further out of the callipers. This means more brake fluid is taken up by the callipers, lowering the level in the brake master cylinder. As the fluid level drops in the master cylinder so the flexible diaphragm extends down. I’m not sure exactly what I did in those videos but if you fit new pads and change the brake fluid then you would leave the diaphragm fully folded up. If you are just servicing the callipers and leaving part worn pads in the the brake fluid in the cylinder needs not to be full (otherwise it will overflow the next time you push the pads back in) so you can extend the flexible diaphragm down a bit. Hope that helps. Skäl. David
@@MotoMirius Thanks, I recently changed tha rear brake disc and pads, but the front ones are due for a change in a while. SO if I read that correctly, I should have the diaphragm fully folded up on the rear brakes, and fully folded down (or at least half) on the front brakes?
Again, thanks for the video. Rebuilding a xtz 660 tenere, and not many videos on this for my bike. But since the xt600e has alot of the same parts this was perfect.
Hello! I'm about to clean and rebuild my front caliper. I have a question about the pistons. I want to replace them, and I managed to get one out by using the brake lever. The other won't move at all, and seems stuck. Is this normal? I'm asking because the revision sets come with just 1 piston. Thanks
Hi. It depends which caliper you have - some only have one piston and the pad is fixed directly to the caliper. But if you can see the piston in there then yes, it's very normal for a piston to be stuck in place. There are various methods of getting them out. There are pliers that help but most commonly air pressure or using the brake lever - if you can lock the moving piston back, you can then use the brake lever to apply pressure to the stuck piston. BUT beware, especially if using air (even from a bicycle pump), if the piston frees up it can fire explosively from the caliper and cause injury (having a piston fly past your head is no fun because of course it's always facing you when it happens), so pad a cloth or similar across it to catch it.
Brakes are the most important part of your bike. It's good if you are confidant enough to work on them yourself, even if you just keep them clean and free.
