Ok so my mini has just come back from its mot test and its failed.
Some of it is easily fixable (a crossed wire somewhere making the lights not work when the ignition is off and a loose drivers seat)

However, the major part was "the breaks bind on to the point you can hardly move the wheels". Sure enough when i picked it up, it wouldnt move when it drove fine on the way there.
Then i noticed the pedal was half pressed, kicked it and all was fine.

What could be the problem? is it a master cylinder failure or is there a spring somewhere that needs adjusting/lubricating?

Thanks

Oh, and it also failed on its emissions, CO level was too high, is this just a case of adjusting the mixture?

On the upside, my clutch seems to have sorted itself out

Thanks again

It could be a number of things, from wheel cylinder seized, to handbrake quadrants seized. Did if the handbrake was ok?

[mattbeddow]

They didnt say.
I took apart the read brakes to check the pads before it went in and adjusted them at the same time as per the haynes manual and followed the instructions to adjust the handbrake.
the car worked fine after i pulled the pedal back up and it would stop the car and release perfectly fine. it was just it was pushed so hard that it locked on and wouldnt come back off

Almost certainly the pedal itself seized on its pivot. They aren't physically attached to the master cylinder - just a ball on the end of the pushrod that pushes into the a cup on the underside of the piston.

...unless it has a servo in which case it could be faulty.

Yeah its a servo type, but im fairly sure its the pedal, just trying to get it off now
