Dispose of or still life in them?

[Crackle]

I've just replaced them but I'm wondering what others think?

You've taken them off, chuck em out, otherwise you will end up with a drawer full of used brake blocks (take it from one who knows)

Chop them in half, see if there are any chunks of metal inside the rubber.

Oh they're in the bin already. Funnily enough I didn't notice too much improvement in the Kool Stops so I've gone back to Tektro pads.

I wasnt impressed with Kool Stops either, swapped them out for Clarks, I will confess i do have the Kool Stops in a drawer though

Look good to me.

Loads of life left in them. Fsck it though, not that important to wear them down to the indicator line.

Yeah but the surface had become quite gritty and they were starting to get noisy in the wet.

Flat em off with a file, loads of life in em yet.

Use them as pencil erasers.

Plenty of life yet. However, there is no grit in those. Koolstop doesn't pick up grit/aluminium. Give them a good scrub and you'll see.
Rescue them, they're good.

You think. I'll have a look again tomorrow.

I usually find with brake blocks that once they fall below a certain level then the brakes don't seem to be as efficient, they feel different, not quite as crisp or responsive, particularly V-brakes.

Yes, if you don't have parallelogram linkages in your V-brakes, they do deteriorate as the pads wear down. That's because they make a cosine error by sweeping down more than sweeping towards the rim. The force on the rim is therefore reduced. With better brakes such as XT, they compensate with a linkage. Those remain good till the last drop.

Calipers don't have the same sweep problem, however on dual pivot brakes the one arm is shorter than the other and when the pad is worn, it does also sweep upwards instead of towards the rim.

That's my problem, crap brakes.

if you look at one of the pads you can see it's more worn than the others. That's off the back and the rear caliper had gone out of adjustment. Just a small twiddle of the grub screw has now brought it back.

Absolutely loads of life!!!!
