What causes the calliper to stick like this?
The pads seize in the slides and don't release correctly. Cars have similar problems.
Corrosion builds up under the steel slide jamming the pad from sliding. Applying the brake pushes the pad onto the disc and it doesn't release properly, hence premature pad wear. The piston side it usually the worst.
The only way to stop this is to maintain the brake regularly but it's not easy on a forza unfortunately.

Two things, budget and design.
Single piston caliper used because its the cheapest option and poor design means it doesn't work as intended and as Alibally correctly mentions, service access to the caliper is a complete joke.

My new policy is to replace the rear pads and clean the caliper every time I change the tyre, that way the amount of times the exhaust has to come off is reduced.
Also worth changing the silencer connection gasket each time as well.

I have had the exhaust off a few times and I don't know if I even have a gasket anymore. Next time I order more pads from eBay I guess I should order a few gaskets.

My brakes don't last as long as my tires. Rear Michelin CityGrip 16005 km, rear brake pad 12041 km. Both were overdue when changed, parts are hard to get here. I guess I should order pads now even though I just put new ones on. The last pads only lasted 3 months.

I have noticed the parking brake doesn't hold that securely. You could ride away not realizing it was on quickly destroying the pads. I wonder if any of the events reported hear could have been due to that. You would only have to make the mistake once.

Parking brake left on isn't the problem, it happens whether there is a parking brake fitted or not.

In Canada we do not even have a parking brake but must use common sense in where we leave the damn thing.

Common sense isn't all that common though...

Common sense would have had the twit in the motorhome yesterday pull over when he noticed that 20 cars were stuck behind him on a narrow 2 lane mountain road. Twat!

I think I may have to pull my rear pads every 2000 km to check and lubricate them. They are not reliable but they are on a Honda but they are not reliable.

These are my last set of rear pads. One is practically new and the other is down to the steel.

That sucks. Which one is the inside one?

I pulled the caliper off today to have a good look. The brakes appear to be good after 2325 kilometers. I have 36500 km on the Forza now.

I think I accidentally got everything right. The Forza coasts a little better now and the acceleration seems faster. The top speed went from 130 to 140 kph.

My oil change light came on today as expected. I did a quick (???) oil change with a Fram filter and Castrol 10W40 Motorcycle Oil because I had some lying around. The Pro Honda HP4M 10W-30 does not appear to be available at any of the Vancouver area Honda dealers.

While I had the tools out I cleaned the belt air filter and had a look at the engine air filter which looks like it should with 7942 kilometers on it. I changed the spark plug (NGK LMAR8A-9) $38.73 from local Honda dealer or $18.04 from eBay UK.

I was going to replace the rear tire with a Michelin Power Pure tire but I will put the tire on my shelf until I get down to the wear bars a little more on the Michelin CityGrip. Last time was such a clusterf*ck with my tire guy getting beat up and the mail strike messing up the couriers. Winter is coming and the riding might slow down. I wanted to wear out the tire before replacing it so I went up to Pennask where it was snowing. Weather reports are now critical.

Also while the tools were dirty it was time to look at the rear brakes once more. This set of rear pads has 4384 km and the fronts have 21513 km but still look really good. The rears are really good still. I think that caliper pin I replaced must have been bent. It spun strangely when I put it in my cordless drill.

Nov 13/16 I pulled the caliper again at 6300 km on the current rear set.

OK for now.

The worn out one was the inside (piston side)

Mine's also looked like that after 6000km. At 13000km they were worn out (1mm/2mm thick respectively).
I checked the front ones at 13000km and they were about 45% worn.

I'm not familiar with other scooter's wear patterns. How does the Forza compare?

One thing I did was scratching Forza's and Shadow 750 pads with an Exacto : the Forza's were
evidently softer...ask Honda why...

AFAIK the Forza oem rear pads are organic which is why they are softer than the oem front pads which are sintered.

Well, both front and rear pad materials on mine look exactly the same (impossible to upload photos
from my Samsung, even at its lowest pixels option).

Also, maybe Honda has made (hidden) changes to the pads...mine don't look at all like Mr. Jones' ones,
shown above...

Then my discs are still near-perfect after 13000km, so I GUESS I'LL HAVE TO LIVE WITH THOSE
BRAKES, isn't it...
