Brake discs

Are the pro action ones any good . First time I've had to change a disc , to be honest the rear is well grooved , but still seem to work fine . Silly question but when do you know they are shagged , when they stop you braking , or do they warp ?, or just dissolve ?

Another question , mine are solid , proaction are wavy , should I stay solid as they are less wearing , if so which solids are best buy ?

Not sure on what make but read the solids are a lot better for wear

On my track bikes i used normal but vented disks.
It seemed if you used sintered pads they would wear them a bit quicker.
I tried wavy disks on my wets and they worked well.
But they seemed to eat pads as fast as disks.
Think its down to fashion my WR has them but when there worn out i may just put normal on it as i don't care how flash it looks i just want braking control.

I have the pro action, fronts are superb, rears wear the pads fast

I'm going to try Rockwell race discs next, they are a copy of the ktms with good writeup and they do a solid disc.

I got pro action ones but have only done 2 rides on them, Changed my front because it had a slight warp the rear was well worn but sill worked ok only changed it because they came as a pair.

These are what Dene fits to customers bikes now Rob. Not bad price. Very thick. Solid disc. Last bloody ages. I will use them when or if the time comes..
