Ashima SOS brake pads

Just thought I'd let everyone know about my experience with these pads. I needed some new Juicy 7 pads, and my LBS only had one Avid pad in stock, so I got an Ashima SOS as well, which I thought would do for the front brake.

Upon opening, the spring which goes in between the pads didn't fit - it was too large, and stuck out over the edge of the pads. I decided to use the one from the Avid pads I was replacing, and this fit a treat. However, after installing the pads, I found they are much thicker than the genuine Avid ones - there is no gap at all between the pad and the rotor. The wheel turned for about 1.5 revolutions and then stopped. I tried pushing the pistons as far in as they'd go, and tried to bed it in, but the pads are still too thick. :(

I have since got a new Avid one, which works much better, and is cheaper to boot. And the moral of this story? Stick to what you know works in the future! :D

    Did you push the pistons back fully before fitting?

    Yes. I got a screwdriver and waggled it between the old pads before removing them, and after having problems, I took the Ashima pads out again and tried to push the pistons even further back. They wouldn't move any further in, and the problem was still there.

    I assume I just got a faulty pad, as they have gotten good reviews, but I won't be spending that much money again just to check! :D

    Seen this a few times with certain pads - only a fraction of a mm too much and the distance can be too little.

    So the pistons were flush with the caliper body or was the system over filled with fluid stopping you push them home?

    The pistons were flush with the body. One of them took a lot more forcing than the rest to make it flush though - do you think it'll be ok left like this, or should the brakes be bled/fluid removed?
