  1. Before installing the new pads,
    thoroughly clean the calliper with
    disc brake cleaner and an oil-free
    rag. Make sure you run the rag
    through the inside of the calliper
    to remove any dirt, grease or
    anything else that could mess up
    your brand new pads.

  2. Make sure the pads are properly
    assembled before installing
    them (some models can be left
    and right hand specific). Most
    will have a spring mechanism
    that holds them away from the
    rotor and stops them rattling. In
    some cases the spring requires
    correct orientation too—best
    to check the manufacturer’s
    instructions if you’re unsure. With


everything in place, hold the
pads and spring together in a
sandwich and slip it back into
the calliper (the opposite of
how they came out).


  1. If your pads were really worn,
    it’s best to check the condition
    of your rotors too. Grab your
    verniers and measure the
    thickness of the brake track.
    With most brands, a fresh rotor
    will be 1.8mm thick (Magura
    is one exception with 2.0mm
    rotors). If your 1.8mm rotors
    measure 1.5mm or less, replace
    them with a new set. Our SRAM
    rotors measured 1.73mm
    (1.8mm when new) so they've
    still got plenty of life left!
