Does exactly what is required. Brakes bedded in after a day or so and have been excellent, no problems.
The front pads had some green "stuff" on them to help them bed in. I haven't had to change disc pads for years (warranties and company cars...) and it is the first time I have seen this. They "grumbled" the first few times I dabbed the brakes but since then No noises. I will use these again when the time comes.
