Caliper slider pin kits.
Most modern cars with disc brakes use sliding calipers. This allows a single piston caliper to operate the brakes. As the single piston exerts force on one pad only, the caliper needs to 'slide' to allow this force to be equally distributed between both pads. This is done by fixing one part of the caliper to a bracket on the wheel hub, and round steel pins to allow the other half of the caliper to maintain it's pressure & keep both pads evenly applied to the disc.
Issues with worn slider pins
If the pins become rusty, bent, or seize in their bores, they can't slide & the brakes get 'wedged' against the disc, usually unevenly, so brakes get hot, pads wear unevenly, or you get uneven braking.
