I am going to assume you have the more recent Saint brakes, BR-M820. A true blockage in a ceramic-piston Shimano brake such as yours that occurs when fluid should be able to flow through as per the bleed procedure is usually a sign that a piece of the ceramic piston has broken off. This is often accompanied by erratic brake feel or function being the symptom ...

Now you're in a fine mess. Putting water in your brake system has most certainly been the death sentence through even minimal corrosion or material incompatibility, ruined the cylinders, the lines and the gaskets. Taking the levers apart will not improve things as most parts will need replacing to be reliably functional again. Think of ordering a whole new ...

Not sure if it's helpful but here is a generic plan for popping pistons with a compressor. Use this kind of blower attachment, with a conical rubber or plastic nozzle. Split the caliper in its two halves and drain the fluid best as possible. Most caliper halves will have one side with the hose inlet, and then when you open it there will be a port for fluid ...

The lever stopping with a firm bite with 2cm to the bar on an Elixir does not necessarily indicate you could do better. Firm means there is no significant amount of air between the master cylinder and the caliper. Those two things can't be true at the same time. Even if a seal leak was somehow pulling in air from outside when you bleed the lever, and even if ...

The operation is easiest using the Avid/SRAM "pro" bleed kit because the syringes seal very well into the bleed ports. The kit is expensive and overkill if you are not a shop. Instead of sucking the top end, you will still get a good result by pushing the fluid up from the bottom provided you have good air free fluid in the syringes. Fix off the ...

Edited - Missed that he brakes are Saint. I have had this occur with a different brand of hydraulic disc. The lever has a valve that closes when the lever is pulled in, sealing the system so the hydraulic pressure builds and drives the pads, and opens when the lever is released, allowing the system to balance as things like heat cause fluid to expand. In my ...
