Are the front brake pads right?

    These are on my Skoda Fabia 58 plate estate 1.4

    All the pics of pads for this car I see are flat, these have a raised area and a chamfer, it seems only part of the pad is actually in contact with the disc.

    Brakes OK and has been through an MOT with these.

    Any comments?

    Its only the left 1/3 of the pad thats in contact with the disc.

    Yes, they are fine matty.....the swept area of the pad will contact the disc at the full width, no problem. The pads are chamfered at the edges so we can see the wear level of them, and to prevent grabbing.
    The discs do look a little moth eaten though, with rust around the perimeter. If they are original you could expect corrosion on the inner, hidden face......which isnt an MOT failure unless very severe.
    Personally I think they could do with a good caliper clean, and lubrication of the pad sliding edges.

    Chamfer

    Standard brake pads can be “pulled’ by the brake disc on application, which can lead to damage as well as poor braking performance and uneven wear. Chamfers offer a transitional edge be- tween two vertices of an object and will likely be present on the leading edge of a brake pad, or on both edges of the pad. In general chamfers are angled anywhere up to 45 degrees and serve three main purposes; to induce even pad wear, to prevent the leading edge of the brake pad lifting and being pulled away by the brake disc and to reduce noise

    The ‘self servo’ action....most prevalent on drum brake systems!

    OK cheers guys, my pad wear light has come on and Im wondering why.
    Last time it was a loose connector.

    I was just thinking the wrong pads had been fitted.My mind is at ease now.

    Its always a good idea to check both sets of pads, matty- both nearside and offside as the pads can wear unevenly.
    This can be due to the disc condition, or the fact that one set of pads can’t slide on its pins due to corrosion.
    The wear indicator is just a copper terminal inserted in the pad that rubs on the disc when the pad wears down, and they aren’t that accurate!
    The same applies on the rear, if your car has discs back there.

    Can be pot luck with some wear indicators on pads. I mean, only one of the four usually has it. I much prefer the audible warning pads.

    These pads were fitted within the last 6 months so I doubt they are worn...
    And the back is hub based..
    when I get a chance Ill check the connector on the left front, thats what it was last time.
    cheers

    Is it the rusty disc edge that's bothering you?

    Not seized and giving a good brake?

    No the braking is fine, its the fact that only 1/3 of the pad itself comes into contact with the disc.
    As it wears down more will contact the disc but now not so much.
    It just looks completely different to any other pad image I can find for the Fabia 2009/10

    Where some may have a chamfer on the leading and trailing edges, these have a chamfer along the top edge (most forward when in situ).

    I think that chamfer would be produced by the disc rust lip rather than designed that way.....
    The only way to see is to take the pads out.
    The discs do look a bit moth eaten but obviously are good enough for the MOT.
    Replacing them gives a more progressive pedal, and changes in braking feel are so slow as to go unnoticed.
