Pumping the brakes puts pressure in lines?

This being an aviation forum, ofcourse all discussion is centered around airplanes. But just for a moment forget them and as you leave for the airport, before you start your car press the brake. Remember the feeling. Then pump the pedal 5 - 6 times and observe how it feels. Stiffer, harder, shorter travel. What you have doen is compress minute pockets of air that exist in the brake lines. They are not supposed to be there, but they are. By pumping the brakes you create a greater pressure in the system and compress the air thus making the system less "mushy". So it makes sense to pump them before use, SOP or no SOP.

Let's see now:
Brakes? No requirement in the before landing check to check brakes in the Cessna 150/172 manufacturer's manual.
Undercarriage. ditto. Seems silly to confirm gear is welded down unless by mistake you happen to have taken the wrong aeroplane.
Fuel? Ditto. That is a constant airmanship thing not specific to before landing check.
Lights? Ditto. Nothing to do with landing.
Instruments? Ditto. Nothing to do with landing as you scan the instrument panel most of the time when flying.
Canopy? Ditto. If the doors were open you would certainly have been aware of it a long time before landing. Even if the doors were unlocked it makes no difference to the landing anyway.
Carb Heat. Yes - on. Now that is a valid check.
Harness? Yes, ensure it is on. Also you must confirm your fore and aft seat locking is engaged
There are so many superfluous drills and checks taught to unsuspecting student pilots that no wonder you need a whole dictionary of mnemonics to remember what they are supposed to represent. I know one flying school that insists its pilots use PPUFF checks before landing. Those letters represent Power Poles, Pitch controls, undercarriage, flaps, and furry and feathered friends. And the instructors actually teach this errant rubbish.
My recommendation is that you obtain a copy of the manufacturer's Pilot Information Handbook and use those drills which are professionally written by company test pilots.

what about M mixture - full rich?
i use a slightly shorter one -
Brakes have pressure, park brake is off
Undercarriage - down and fixed
Mixture full rich
Prop set - fixed pitch
Fuel - primer locked, selector on fullest tank, quantities ok, pump on, have pressure
Harnesses - on and tight, doors latched
Landing light on.
For a CSU/cowl flap/retract aircraft, on finals i do a CUP check, Cowl flaps, Undercarriage down, Prop full fine.
works for me. i haven't landed with the brakes on yet.....
