Before reinstalling your pads, measure their thickness. Anything
less than a millimeter of pad material, in addition to the backing
plate, and it’s time for fresh ones.
Double-check that all surfaces in and around the brake caliper are
clean. Frames and brake adapters love to hide small pools of fluids that can instantly contaminate pads. Once everything is clean,
it’s time to reinstall the pads.
The best method for putting the pads back in is to make a “spring
sandwich.” That means you should position the H-spring between
the pads and then squish everything together.
Once you have your brake-pad spring sandwich, slide the pads
back into place.
Most brake manufacturers make a plastic pad spacer chip that’s
designed to perfectly space the pads before the rotor is installed.
These typically come with new brakes, but can also be found at
the local bike shop. Ask your favorite shop mechanic for one for
your model of brake and add it to your toolbox.
Don’t forget to reinstall the pad retention pin and torque it properly. Failure to do this can result in your pads flying out mid-ride and
could cause a nasty crash.
