Question ABS preventative maintenance

I hope 'General' is correct, I feel this applies to any ABS equipped model so I hope I've picked the right forum.

I recall a recent thread started by a member who had an ABS pump failure. There was some talk around correct bleeding to include the ABS system - but also the importance of regularly activating the ABS so it does not get seized up and to keep fluid moving. Damned if I can find the thread again though.

I'm trying to apply that advice and stomp hard on the rear occasionally to activate it. I'm less enthusiastic about doing the same for the front, it takes some serious braking force to make that want to break free.. but I've just realised they're not separate, there's just one pump.

So does that mean that just activating the rear will give the preventative maintenance benefits required? Or is it more than just the pump portion, do we need to get the solenoids for the front going too? Is there someone who knows ABS well enough to give some advice?

If you find a bit of dirt or gravel it will be easy to activate the abs at very low, safe speed.

I like to regularly hit a deserted section of pavement and at 20 mph grab a handful and activate the front abs. It's easy and helps I think to build muscle memory for that moment of panic when the moose steps out of the woods into your path.

I had concerns about activating the front brakes that way too, before I did it. But you have to keep in mind that the whole point of ABS brakes is to prevent the wheel from locking up when you activate them. The front wheel isn't going to lock up when you grab a handful of brake lever, and the wheel isn't going to wash out and cause you to crash. In fact, I think it's a good idea to deliberately activate the ABS on both wheels every once in a while; one, because it cycles the pumps and dislodges any old brake fluid left in there, and two, so you know what it feels like when the ABS is working.

It's way less scary to activate the ABS on a gravel driveway, or in the yard.

Thanks for the input guys. I do like to regularly practice some serious stops from 50/60kph like I had to learn for my license test to stay sharp. '4 finger, progressive squeeze, lock knees on the tank or else you're going flying' kind of stops, but it still feels like ABS activation comes at a whole next level. Still, one reason I have an ABS bike is because I've experienced that panic moment before Maybe I still need to get more comfortable with making the front end hurt.

So perhaps it's a moot point if I just sack up and get rougher on the front brake, or find some convenient gravel

Still, I'm curious to know from a technical standpoint, and how I can help avoid spending $1500+ of farkle tokens on a new ABS unit one day.

As part of a systems check, shouldn't or doesn't or could not the onboard computer cycle the ABS pump very quickly when the key is turned to On?

The biggest part of maintenance is flushing the old brake fluid and replacing it with new. In all the cases of ABS pump/control unit failure Ive had the cause was old, black, slimy brake fluid.
I remember the original post, and I found it curious that the shop that did the brake work said a new ABS pump was needed, but the owner experienced no brake issues or ABS warning lamp staying on. Then again, did the shop perform an ABS brake stop? Did the owner? Sounded like there was a missing part of the story. How do we know the bike actually NEEDED an ABS pump? Was the correct brake fluid bleeding procedure followed?
In my bikes, I make it a point to change brake fluid once a rear, ABS or not.

I activate my ABS quite frequently on gravel, it's amazing how well it works and it's good to exercise the system.

Is there any way, electrically, to activate the ABS pump?

It's simple math.
