[Closed] Puffer and brake pads.

5 laps started with a set of fairly new Hope own brand pads I think they are sintered anyways quality pays they are still on the bike although I was running the mud slop by the end to save the bike a bit from pad wear and chain suck (and unless you are a God of Biking like Our Dan it was quicker).

They are still on the bike and working fine. Some folk just brake too much if you ask me...

Disco brakes generics for Formula. Finished off one set that were part worn and now part way through another.... so one set really. Didn't shape up as badly for pad eating as I anticipated when the thaw really set in.

Oh, and that was over my 13 laps, d'you hear that? [b]13[/b] laps!!! or haven't I mentioned it? 😉

Hope sintered original. Started off with half worn front and rear. Replaced rear after 3 laps with originals, fronts after 5 with ashima. No further changes needed and both sets look unworn. After the changes tho I did make a real effort to heat up the rears on one of the downhills and didn't go fast enough to need much front brake.

This is the only time I have experienced rapid pad wear. I still support scienceofficers analysis of why it happens abut will now give more credence to the person who suggested that some of the wear may be "just riding along" when you hear that skeeshing sound of grit in your brakes.

Feally really abrasive conditions - but I have done far more miles in nearly as wet and gritty without the pad wear so I still believe heat is the biggest factor.

I started on 'disco' pads for avid juicy's. Rear set lasted 2 laps until it was metal on metal, front lasted 6 laps. Replaced rear with 'superstar' sintered which lasted another 4 laps and is not bad. I think the first half the race ate pads with the paste on the fire roads. When that froze things improved greatly.

3 sets of disco sintered pads in front and 2 sets of disco sintereds in the rear over 17 laps.

my bike is a mess ! Rear caliper is just a muddy ball bolted on

Terry brakes too much.... 😉

TJ would you not give any 'credence' to the differing composition of various 'grinding pastes' found at different races? The rock and therefore the grit at the Puffer might be particularly abrasive. Granite isn't it, or have I got my Geography wrong?

One set of Avid organics lasted the race on a rear bb7. Front went through one set of organics and one set of Superstar sintered.

It's quartzite in the puffer paste that makes it particularly abrasive.

i have sids and ss .....front end is like a wet noodle when i start yanking on the bars.....

And how much lube did you all get through ?

I lubed up with some white lightening wet ride purple lube won at puffer lite on friday night....... I then rode my bike till sunday 9.10 without so much as looking at it again.....

Jojo - I am sure it has a significant effect but not enough to account for the thousandfold difference in wear rates.

I have also ridden in Peat / quartzite mud without massive pad wear - but under conditions that are not so cold. and with quicker descents where you get more heat into the brakes.

Just from attempting to make some sense out of all the data - its a puzzle that amuses me to investigate.

There are may factors involved but temperature of the friction surface seems to me to be the critical one. Composition of pad and mud has an effect for sure but some people get massive pad wear and some don't in the same conditions ( wet Afan / peaks etc) so there must be another critical factor.

Science officer did an analysis of this that gets as close to the right answer and as convincing an explanation as I have seen.

Terry's brake caliper.

Lube - alfine hub here. Chain lubed with Putoline chain wax. Still perfectly lubed after my 9 laps - still got grease in the rollers. NO wear evident at all
