Ajusting EBC brake shoes to fit

[talkToTheHat]

So I finally took the bike in for new tyres today, I might have tyres that have tread and aren't square for at least some of the winter

Whilst the back wheel was off I thought the rear brake shoes (yes shoes, ebc code Y515) might as well do with a replacement as I was running out of adjustment. I'd usually do brakes myself but whilst the wheels were off most of the work was already done. Asked for SBS but as there's a 9 week backlog some EBCs were ordered for me and were about 20 quid so I was initially quite happy.

Then they tried to fit the shoes. Wouldn't go in. They ended up grinding down the parts of the shoe body that contact the pivot pin and operating cam. It all went together and I think the time spent piddling with the shoes was eaten by the flat rate tyre fitting already agreed so I'm not out of pocket. The brakes work as well as I tested them, a few miles home via morrissons and a few extra times around the carpark, being gentle as they bed in.

Anyway, my question: Is this a normal/accepted practice? Do the shoes have any kind of case hardening or suchlike that would be damaged by this. I think they're cast aluminium but I'm not sure. Should I be worried? Changed a few brake drums on cars and not run into this. Am I just being paranoid?

Had to take the excess paint off of the brembo front pads too, but that's paint and on a locating tab not a cam/pivot surface. That I've done before with cheap kyoto pads on a 125.

It's quite common for pattern shoes of late to require fettling. Don't worry to much about it.

I've had to do some minor filing to EBC disc brake pads to get them to fit properly.

The flat bit the cam acts on sometimes has a hardened insert on drum brake shoes.

If you didn't chuck them, you can probably have new pad material fitted to the old shoes. Wasn't unusual to do service exchange on brake shoes. They still do on enfield bullets.

Old ones went straight in the bin. Might be retrievable. I couldn't see an insert on the originals or the ebc replacements, both looked like a one piece casting with friction material attached.

I think the old ones might have been in there from new. Could probably get another 5k out of them. Does friction material deteriorate with age or are twenty year old shoes still as good as they day they were made?

Almost certainly deteriorates.

First hit on google shows £18 a pair for relining.

In the pic you can see the steel insert that is operated by the pivot cam of the back brake lever

I have bought some EBC shoes for my Honda XL250SA in the past.They went straight in without any modification - but they were rubbish.Even after some 200 miles of green laning they had still not begun to bed in and to give me some decent stopping power.So I bought some expensive genuine Honda shoes and the differance was immediate,with decent retardation from the start.

Can see the insert on those, pretty sure there wasn't such on the Y515 pads as they were supplied.

Brakes work ok, more compressible than before but it's easier to be confident how hard im braking with a big boot on. Not tested the limits too far yet, but getting a surprising amount of kickup from the front forks if i come to a stop on the rear alone. Brembo blues on the front are the opposite, much less compressible than the pads that came off, slightly less dry initial bite (possibly as still bedding in) but I'm finding myself stopping short using just the front, and I've noticed less variance in the wet and cold.
