Front Discs

Discs & braided lines fitted and tested on my 30mile work journey tonight.
FINALLY got rid of that horrible "bounce" at low speed.

Personally, I'd use those.  They may take a few miles to bed in, but so do new pads.

I know it's an old school thing to do but if you're fitting used pads to new discs, you can assist the bed in process by "facing" the pads.
Turn them friction side down on some smooth concrete (or a large sheet of 400 wet and dry if you have someone else who can hold the edges down!), then complete multiple "figure of 8" movements holding the pad. Turn it 90-180 degrees occasionally to ensure it's wearing flat. Repeat process until all old score marks are removed from the pad. Repeat for all pads.Clean them. Fit them. Use them.
@grog may verify if this is still an acceptable method to use?

Agree Mate. Not often new rotors fitted with used pads, quite often with just a disc machine. A bit of a wipe on concrete works well. 👍 Thats car stuff im talking about. Bike pads would be the same.

Yep, if they were grooved / rutted I'd do that, no prob.  Get 'em flat n you're all good

Back when cars had points, even bikes did, flatten on smooth concrete was a great option.
Off topic but hey, once tuning old gt750, adjusting points/timing. Had spanner on crank bolt just turning over to each set of points. Hadn't turned ignition off. Wow, how far can a spanner fly when motor starts. A bloody long way. Just remembered that one.

Please kick me out for being off topic but just remembered that one.

Hahaha-would've loved to be there to see that!
