I tend to nip and then back off slightly. You can then make sure the disc spins freely and the thrust washer can be moved.
You're getting the addiction for using brake cleaner I see, invaluable stuff

I agree with the nip and back off - I found that there was more play on the washer upon checking after running a few miles with new bearings.

Still a bit more play than I'd like but a tiny bit of play always feels like more than it is.
Caliper carrier on and discs cleaned, I already moved the caliper piston back a little
caliper back on with threadlock on bolts and copper grease on pad contact points
make sure caliper moves freely and stood on the brake pedal, still feels like more brake pad resistance than there should be

OK not peened yet will have another go, thanks both.

I would work the caliper piston back and forward to free it off before final reassembly then.
It's handy to have some old pads lying around that you can use to force the piston back, assuming you don't have a caliper wind back tool.
I never bother putting thread lock on caliper bolts, and never had one come loose yet.

they are new calipers last year and free to move, I will compare to the other van.
I use a socket in the piston and a quick clamp to push them back, I once left the socket in the piston, took me a while to work out what the clanging noise was when I went over bumps

marked the nut, nipped up and back off until thrush washer just moved and it ended up in the same place
ran out of time, finish tomorrow.

Careful you will have the Health and safety police after you saying stuff like that

Oh and after putting brake caliper back on you can't feel the horizontal play anyway so maybe the old bearings were OK after all

Jacked the other van today and wheels spin the same with than same amount of pad resistance so sounds OK to me, I can spin the wheels by hand and get about 4 turns before they stop.
Bearing play in the other van is greater, bearings were done 10 years go and it never occured to me to adjust them
job in the list.
Quick Q do people peen into one slot or both?

not sure if it's against engineering protcol to hit a pin punch on the side but it gives a nice peen
cap back with some grease on the mating surfaces to help stop it rusting on

Nice work Paul. Did the same job myself recently albeit without the lathe-turned tool to press in the race. I found a large socket worked for the external race and I used an old cotter pin for the inner but you have to be really careful.
