Nissan Micra 2001

The car has a "long" pedal, but stops as normal.
There is no loss of fluid and the linings are good.
There does not seem to be air in the system on pumping.

I am thinking master cylinder. Any other thoughts?

im thinking either rear shoes need adjusting, wheel cylinders leaking? id check this first before you pull the master back to see if it is passing.

Could even be worn front pads too.

Take wheels off and have a look!

Fluid may not have gone down too much even tho pads may be down.

Always worth checking!

Tried this: no effect on pedal.
I am sure rears are correctly adjusted.

Pads and linings are good.

you will probably find the rear conpensator valve is seized it will need carefully freeing off.
Easier to do on a ramp/pit as you dont want the back of the car in the air as you do it.
Do not pull the adjuster too far down or the piston will pop out and it will then be scrap,very carefull oiling and twiddling usually sorts it,cover it in grease when done.
While you have your head up there have a look at the floorpan above the fuel tank,nissan didnt put any paint up there other than primer so now would be a good time to waxoil it before it gets terminal rot,also the front crossmember as they rot inside out especially nearside front where all the panels meet.
