Re: What are the chances of double brake failure?

For completeness:

The pads measure less than 1mm thick so I guess they were more worn than I thought.
I put another Clarks pair in but I’ve ordered a couple of pairs of Nukeproofs to see if I get more life and less noise from them.

Re: What are the chances of double brake failure?

:oops: I see what happened, I took a picture of the wrong spring - that one must have come from the rear calliper which is a TRP Spyre. I’ve just found the front spring - it’s damaged on both sides which clears up my puzzlement over the damage to both the front pads.

Re: What are the chances of double brake failure?

As the OP, I can say with certainty the spring is the one supplied with the pads (Clarks).

I wonder if the spring was misaligned initially as I know I found installation of those pads fiddly.

I will measure the pads later.

Re: What are the chances of double brake failure?

You've clearly got different brake models front and rear. Not sure if this actually makes double failure any less likely. The front pads don't actually look that worn to me. I wonder if the spring failure wasn't caused by metal fatigue rather than wear on the pads bringing it into contact with the ...

Re: What are the chances?

The front pads both have a piece missing in similar places which struck me as odd.

The rear pad failure may have been partly a result of rust on the backing plate - I rarely use the rear brake and these pads had been in for more than 3 years.

What are the chances of double brake failure?

On the way to work recently I had a front brake failure - there was a ping then a scraping noise. Here’s the resulting damage: D3B4ED5F-1910-4126-B5C6-B9E10307FB60.jpeg I carried on with no front brake. On the way home later I had a rear brake failure - one of the pads seems to have come off the bac...

Re: Spiked Tyres for 650B

I use Marathon Winter Studs. This week I used just a front tyre on the icy roads which worked out fine.

I don’t really see them as snow tyres - it seems to me that fat knobblies would be better for that.

On the other hand, for well frozen hard-pack snow, front and back studded tyres can work well.

Re: black ice

I misjudged the weather this morning and hit black ice and ended up on the road - one very bruised thigh! Caught out by the road surface on a small bridge over a little river being colder than rest of the road. Air temperature about 3 or 4 degrees but had been colder yesterday and was drizzle in th...

Re: black ice

I believe the forecast air temperature is usually for 2m above the ground, hence the air next to the ground could be lower unless the wind keeps the air mixed.

Often, gritted roads are damp when ungritted roads are dry which confuses the issue somewhat.

Re: ** The Brexit Thread ** - 'Brexit Means Brexit'

As far as I can tell from a quick bit of googling, fire extinguishers can still be colour coded with a coloured band and (not surprisingly) there is a justifiable reason for making them all post box red.

Re: Chain bouncing off

If it's going slack on a weekly basis then maybe the answer is a chain tensioner. Obviously depending on your frame this may not be a trivial solution ;) Well, it’s not really going slack, or at least probably not by your meaning of the word. I might take a picture later to try to indicate the leve...

I can fix it but I prefer not to have to fiddle with the bike on a weekly basis.

It’s not particularly slack which is why I found it surprising that the chain bounces off. As I said, the previous chain was fully bushed and was much less prone to derailing.

Re: Chain bouncing off

I commute on a single speed bike and I’m getting this issue since I put the current chain on - KMC S1. I realise I could keep the chain tighter but I’d rather be able to run it with a little bit of slack. You may have adjusted it with too much slack when you put the new chain on. You should have ab...

Re: Chain bouncing off

if your chainring doesn't have full height teeth (because it is really meant for a derailleur system) then that is likely where your troubles lie IME. I suggest getting a chainring with full height teeth if you don't have one already. BTW a KMC B1 chain is fully bushed and is less flexible laterall...
