What is weird with Elixirs is that even when you use the correct bleed block, the pistons aren’t fully retracted. I keep meaning to use a feeler gauge or some shim material (coke can, perhaps) to bulk out bleed block a bit, so the pistoons are fully retracted when it comes to bleeding.
When they work, I love the way they work. They are poweful, but without that on/off feel that you get with some brakes. You can really modulate your braking.
But, I don’t have time to keep up with bike maintenance as it is and brakes are one more thing I’d prefer not to mess around with. So when the time comes, I will definitely be replacing them with another brand; probably Shimano SLXs.
