Brake fluid changing
I do get my partner to pump the brake and when I see no more bubbles in the fluid just do up the bleed valve.
Very clean and quick.

Turkey baster to suck the old fluid out of the master cylinder reservoir. Then top off with new.
Jar on the ground with some fluid in it.
Clear tubing from the bleeder on the caliper to the jar, with the end of the tubing in the fluid.
crack the bleeder and let gravity flush the system. Top off the master cylinder reservoir and dont let it suck air.
When the fluid in the tube is clear, the system is flushed.
it takes longer to read what I wrote than to do the job.
if you want it faster, pump the master cylinder lever/pedal. With the end of the tubing in the fluid in the jar, nothing goes backwards.
This is what the front wheel cylinder looked like on my 64 impala after 20 years of not changing the fluid.
The other side wasn't much better.
Good pic.... that's why I think it's a must do on all cars....... Since there are relatively few catastrophic failures, people are unaware of the damage caused from not changing brake fluid, and the degrading effectiveness of their brakes happens slowly, so most unaware their brakes have lost a step. They don't believe changing fluid is necessary.
I remember, as a young guy (8-15yrs old) helping my Dad and our neighbor change drum brakes in the older cars. My Dad & neighbor were both car guys that fixed their own cars, and helped neighbors fix their cars too.
Just about every brake job they did, at least one of the the brake cylinder seals needed to be changed. And every time we opened a brake cylinder, there was always a layer of rust and occasional pitting. We had a honing tool that we used to hone the inside of the brake cylinders... In retrospect, I'm sure the brake cylinders would have been in better shape if people had changed out their brake fluid back then... but nobody did... at least not until they need several brake cylinders repaired, and then the fluid was pretty much flushed as part of the repair...
I have to wonder how many ABS modules/calipers/brake lines, across all types/makes/models of vehicles, are replaced out of warranty... and how many may not have needed replacement if the brake fluid was changed on some kind of regular schedule...?

In those days, even if they leaked, you could reach down and pull the emergency brake to stop - with our bikes if you have ABS module failure, you aint got chit!
The mess the MoCo has passed on is not like going back in time - it's just plain effing up!

I'm a big advocate of DIY maintenance which is why I created my HD1 and HD2 ABS Flush Utilities.
