Review on 🔧 Jagwire Elite Disc Brake Bleed Kit: Efficient Bicycle Repair Tool for DOT and Mineral Oil, Compatible with Popular Brands - SRAM, Shimano, Avid, Hayes, Magura, and More! by Tim Paolucci

The spacer block that comes with it is too small for Shimano 8120 Deore XT two piston calipers. This can twist the pistons in the bore, jam them and destroy the caliper. The kit is otherwise good, but even a fully seated and bolted block only rides halfway over the large piston, and when pumping, the pressure from the levers is enough to force the ceramic piston out of alignment. If you're lucky you can return it without breaking the seals. I was not. $250 down the drain. I keep it, but every time I use it, there will be bad juju in my heart.
