My fiesta zetec s front discs and pads are wearin unevenly, the top half of the outer pad is the only bit that contacting the disc. i've changed discs and pads with no change. Anyone any ideas? calipers aren't sticking, plenty of grease on everything.

 

ONCE BEDDED YOU'L GET FULL CONTACT ANYWAY!!-HAS THE STRUT HAD A KNOCK!!-TRY A RUN OUT DIAL GAUGE!!---- IT WILL EXPOSE THE PROBLEM/CAUSE AND HELP YOU TO CORRECT IT

 

is it me but in the picture there it looks like the part of the pad not touching is actualy thinner thn the rest of the pad. is this right or just camera angle?

 

Caliper pins are sticking very normal, especially for people that use the wrong grease on them.

tabetha, can you please explain what you mean by caliper pins sticking.

im not moaning i just want to know too for future reference.

is it the pins that you need to remove to change pads? cause i cant see how this will matter.

 

I mean the pins on which the whole caliper slides, they don't work particularly well at sliding and so actually jam in place as you apply the brakes.
Theory dictates that for every action there is an equal and opposite reaction, ie the pad pressure should be equal on both sides of the disc, they never are, I have eyet to see a set of pads with pin sliders where both are worn equally, the only thing that could cause this is sticking of the pins.
In addition developing a taper on one pad is not that unusual either.
Clean the pins off and use SILICONE GREASE on them.
