February 9th – A puzzle, for sure. Shimano metal sintered disc brake pads for hydraulic brakes: what happens to them that renders them useless beyond recovery?

Usually the rear set, all of a sudden they loose stopping power,  and often become screechy. They are not contaminated with oil, although it feels like it. Deep cleaning in the dishwasher doesn’t work. Ultrasonic cleaner with solvent doesn’t, either. Neither does surface grinding as much as .75mm off the surface.

It’s like they just glaze, and some structural or metallurgical change takes place, and that’s it. Only thing to recover stopping power is new pads. Or using them in the rain; when wet, and only then, do they stop better.

At £20 a set, this is not fun. Anyone any ideas please?

February 26th – In Birmingham at twilight, I was without any kind of tripod, so practiced a steady hand. I used to pass through Colmore a lot, but in recent years barely at all. When I was here a lot, there was a Somerfield where the Costa is, the Waitrose hadn’t been built and the Sainsbury’s was a Marks and Spencer. It was never this handsome at dusk, either; several of the office blocks here are relatively new.

Like Walsall, Birmingham is not mine anymore; places I was familiar with, things I remember, bars, cafes and shops I haunted long gone. Yet I still feel at home here. 

Unlike Walsall, change has always been Birmingham’s modus operandi. And it’s getting better and better at it.

May 7th – A snatched picture combining two of the worst hazards in cycling. One is common, the other seems unique to a particular part of Darlaston. The loose grit – marbles – I’ve discussed at length here; wheel and traction stealing, highly polished grit, it washes down during rain and snow, and gathers in junction voids and gutters, waiting to snatch your bike from under you.

The unique hazard is metal clippings, swarf and shards, and this is Heath Road in Darlaston at it’s junction with Station Street. Around Darlaston Green, all the way down to the Walsall Road this problem slices tyres and causes punctures. Open tipper wagons and skip lorries corner here to get to the scrap yards up the road, and metal drops through their tailgates, shutterboards and  from unsheeted tops. The metal lies flat in the road, where it’s gradually sharpened by the traffic dragging it against the road. 

Automatic sweepers don’t pick it up because it’s so thin, but hit it with your tyres and you’ll quickly flat. It’s a pain in the arse. Look closely here and there’s sharp spikes, wire and razor-thin plates.

Look out for it; avoid the area if you can. In a place where one has to watch the traffic carefully, it’s another hazard to watch out for.

August 23rd – Rust never sleeps. A couple of years after installation, Walsall Wood’s iron cutout people look dreadful, in my opinion. Had they been coated, or made from stainless steel, they would have worked a whole lot better, but the rusted, corroding versions just look like visually confusing scrap these days. The text milled into every figure is very hard to read now, as there’s no contrast due to the oxide.

A wasted opportunity. Walsall Council paid thousands of pounds in development funds for this. Surely a more enduring use of the cash could have been found.
