Most overlooked brake maintenance procedure. Note: When pushing the pistons back in, make sure you're pushing them straight in. If you're pushing with an angle then the piston will get stuck. Hold the other pistons down and pull the brake lever so it comes unstuck. DON'T try and push it in with force if its stuck. It should go in smooth with little force.

I have the RX4+ callipers (shimano version) which use Shimano mineral oil. My understanding is that the silicone lubricant should not be used with mineral oil. I've just used the mineral oil to lube the pistons. I know most Hope brakes use DOT fluid, but might be worth clarifying this.

I’ll try the piston lube on the road 4-piston callipers. I’ve got mine perfectly centred having just fitted them but whatever I try the front brake always rubs after the brake has been applied (pistons don’t retract properly). It’s doing my head in having spent an hour trying to sort it out following the Hope guide step by step.

Thanks for making this video, I've watched the one you guys posted years ago a bunch of times. I have the V4 calipers with regular rotors (not vented) so the pistons have to be pushed out more than normal to bite. I noticed that the pistons don't all push out at the same time (one or 2 always seem to stuck or slower. I am pretty sure I need to lube them but I can't find the lubricant anywhere. What lubricant do you recommend that I use to lube the pistons?

nathan fagan Mine were like that until I greased the pistons and worked them in and out over and over. I took the wheel off and wedged a plastic screwdriver between 2 of the pistons to hold them back, then pumped the break until the other 2 came out a long way. Dab of silicone grease all the way round with a cotton wool bud and pushed them back. Do the same with the other 2 pistons. Once they are greased take the time to keep pumping the pistons out and push them back until they all move the same when you pump the brake.
