Well thought I'd add my experience with the pads on my RT (16v brake conversion)... basically.... I DO
NOT LIKE THEM. Now before I start saying the pads are rubbish, they are not rubbish, I don't like them on my setup that's all.
I have Brembo Discs and I think the compounds must not work well with each other, especially because the Mintex Pads are a metal compound. I get alot, and I mean alot of brake dust from these. However this increase may be worse due to grooved discs taking more surface off the pads under braking.
Secondly, the most important point, they sqeual really really badly under gradual braking. Normal to aggressive braking is ok, but trying to come to a gradual stop or braking whilst going down hill and the noise is terrible.
I am going to try out Brembo's own pads (they do make there own don't they?) and see if that helps matters. My brother had this trouble with his M1144 pads and Red Dot discs.
The braking is good but I can't put up with the noise and amount of dust. Like I say, it may be the type of discs not helping, but we'll see.
