Second, the slide pins may stick, causing the brake pad to continually contact the rotor, resulting in a buildup of heat, which wears your brake pads down faster.
What do you lubricate drum brakes with?

Do new brakes take time to bed in?
Concern – The brakes need time to “bed”. This is the period where they go through heating/cooling cycles. It is a period of time where the “glue” (bonding agent) has time to fully cure. If you are not easy on the brakes during this time, the glue will move toward the surface (towards the heat).
