What is this bloke on  :thumbdown [size=1em]rotate your pads, so they last a bit longer [/size] :eek  this is going to end in  :'( DON'T do it.


The fact the pads are worn uneven is telling you something is wrong especially with any opposed piston caliper.  Basically one side of the caliper the pistons have started to seize or the the pads are seizing in the caliper body.  Pads wear to the disc turning them around means they aren't now parallel to the disc and therefore have reduced surface contact and until they wear back in reduced brake force, depending on the condition of any given disc this could mean almost no brakes!  This is madness to save a few quid or because you don't have the know how or can't be bothered!

[size=1em]If you pistons are sticking any quick fix i.e. pumping them out against something to free them is just temporary they WILL seize again.[/size]

[size=1em]If your pads are wearing at uneven rates or at angles (front/back - left-right) there's something wrong.  I've made many post here over the years there's no short cut here and there're many reason why they wear this way, cheap or poorly fitting pads (EBC were and still are terrible on certain bikes) lack of maintenance, wrong maintenance.  [/size]

[size=1em]U tube is full of this stuff but this is almost the worst I've seen, it's bloody dangerous[/size] :eek :eek

I just watched this and the main thing that struck me as being a bit naughty was jacking up the bike and putting a lot of pressure onto the side stand and making the bike very unstable.
I wonder if anyone's ever tipped their bike over when trying that?
