When my original brake pads wore out I replaced with Aztec pads. Very soon I began to develop some severe squealing - normally a sign of contamination but I could see no reason for that to happen, especially on both front and back.
I've now replaced with original Shimano branded pads, after first thoroughly cleaning the rotor, and the squealing has gone. Not only that but stopping power on my often heavy laden Specialised Crosstrail is much noticeably better.
Sticking to original Shimano pads from now on.

I've had my hybrid bike for just over 3 years and use it every day, up until recently the hydraulic disc brakes have required no maintenance. They started squealing very loudly over the past few weeks and it was getting to he point where I was afraid to use my brakes in fear of the racket they made. I tried cleaning the exiting pads and used brake cleaner on the discs which did work for about a week then I decided to invest in these. The old pads did have a fair amount of surface left on them but were showing signs of chipping and wear on the edges. These replacements have completely eliminated the squealing and were very easy to fit. Two sizes of split pins are provided if you don't want to reuse the old one.

Disk brakes were making a grinding noise, pads looked OK but disk was worn so I thought I would need to replace the disks. Before doing this I decided to see if replacing the pads would make a difference and it did - the grinding noise is gone.
There is a slight difference to braking feel (needs more pressure to stop but doesn't grab so much) so took a bit of getting used to but this saved the cost and difficulty of fitting new disks.
New brakes are effective and the bike feels like new (but I also replaced grips and chain...) I recommend replacing pads as a first step as the old pads were glazed, hence the grinding noise.
