Knowing how to change brake pads can save you a few bucks and shouldn’t be all that difficult. The brake pads are the part of the braking system that is pushed into the rotor (or disc) by the caliper to slow the car down. Normally brake rotors last longer than the pads and won’t need to be replaced unless they are cracked, warped, rusty, or too thin. Brake components should be replaced on both sides at the same time, and since pads are usually sold in pairs there’s no reason not to do both sides together.
The first step is to jack up one corner of the vehicle and support it safely. Next, remove the wheel. With the wheel off you should be able to perform an inspection on the condition of both the pads and the rotor. For a more thorough inspection or to change the pads you will need to remove them from the the caliper. This process varies by vehicle, but the first step normally involves removing the caliper from the caliper bracket by removing a couple of bolts and then rotating it off. Once the caliper has been removed the pads can be popped out. Don’t let the caliper hang by the flex hose as this could damage the hose, instead support it on something like a block of wood.
