So I'm having some trouble aligning my calipers on the rotor. When I took them off, I noticed that my calipers have the notorious "dominant piston" problem. After doing some searching here, I cleaned up the pistons as best I could by holding the "dominant" piston back and pumping the brakes to push out the weaker piston.
It seems like wherever the weaker piston is, it doesn't stay pressed out like the other piston.
I thought that there might be an air-bubble in the system too, so I went ahead and did a bleed, but to no avail.
Do I need to drop $20 and get a complete rebuild kit? Has anyone done this? How difficult is it? Thanks in advance for any info.
