I fixed the pedal lever on our kitchen bin.
We'd noticed the lid only lifted if you pressed the right-hand side of the pedal. Not good as it's less than a year old and 50L pedal bins are hard to find.
The pedal and lever is a plastic moulding – a hard polythene-like stuff, Kematal or suchlike – with a pivot sticking out either side which it would be a bit OTT to describe as 'moulded'. At the back end is a springy barbed protrusion that operates the thick wire pushrod for the lid. After a bit of a fiddle, you work out that you can lever aside the plastic walls that contain the pivot fulcra, pull out the pedal and disengage it from the pushrod.
What had happened was that the plastic sideframes of the pedal lever had cracked in tension, the left more seriously than the right because the crack was at the pivot.
I made up some reinforcing plates out of 1,5mm alli, drilled 'em 13mm to let the pivots through, then pop-rivetted them with 4mm x 8 long rivets fore and aft of the pivot. There wasn't really enough clearance between the fulcra to allow this extra width to swing freely, so I had to grind off most of the thickness of the rivet heads.
I'm hoping that won't matter.
The bin's reasonably well-designed, but a poor piece of work in manufacture. It was made in China, but I've seen stuff just as badly made in (eg) Birmingham.
