New to CB400 four and new here! Front brake improvement?
McCabe-Thiele (Ted):
Interestingly back in the 1960's my late father would always advise car owners not only to bed in new brakes but tyres as well.
Then again back then a new car had to be run in for the first 500 miles or so.

Drum brakes (extensive in that era) are significantly subjected to circular irregularities in surface of friction materials and shoe pivot point variables. Getting them all worn so they touch competently of good advice certainly.
Anyone hold the rear brake on while torquing the wheel spindle during wheel installation ? At least takes out any available variables in brake plate position to help as best possible the alignment on them.
Moto-X drum brakes of past era's are usually a bit wide toleranced when it comes to brake plate on spindoe location. Especially with twin lead design, often significantly improved by this tightening method to get both shoe working to maximum effect.

Standard procedure for old Brit bike drum brakes. Does make a difference.👍

Went out today to "bed in" the brakes per Odjob's post. The Results?
FANTASTIC! It is orders of magnitude better than previously and stops with authority now where it used to be "scary." Of course, since I changed pads, caliper piston and seal, and brake lines I can't say whether any/all of that contributed or was it just new pads/proper bedding. In any case, I am quite pleased with the brakes and with the help of folks on this site!!
As soon as I got back I let the bike cool a bit and proceeded with the next project - pulling/checking/adjusting the carbs. Pulled them off with no drama at all. I want to have them sorted/back on the bike for a ride on Friday. Hope I don't need any parts other than the various o-Rings. I have those and new carb screws from Nurse Julie.
Bryanj:
Several big aerosols of carb cleaner or better still an ultrasonic cleaning bath
