The Honda Accord utilizes four brake discs (brake rotors) for braking. These rotors rarely need to be replaced, but if they become warped or worn down and can't be resurfaced, then it's time to swap them out for new. The process for changing rotors is simple and you can save plenty of money by doing the labor yourself.
Buy a new set of rotors for your Honda Accord. Ideally, you should change all four brake rotors at the same time, but you can get away with changing just the front or rear end pair at the same time. Never replace just one, as this causes uneven and unsafe braking.
Drain about half of the brake fluid from the master cylinder to prevent overflow. Jack up your Honda with car jacks and jack stands. Block the wheels to keep your car from rolling while you work. Remove the first tire and wheel assembly and set it aside.
Undo the caliper mounting bolts. Slide the caliper assembly off of the old rotor. Hang the caliper from the car's undercarriage with mechanic's wire, being careful not to let the brake hose get disconnected.
Remove the holding screws on the rotor. Next, pull the old rotor off the studs and clean the hub and surrounding surfaces with a damp cloth.
Install the new rotor and fasten the holding screws. Discard the wire and slide the caliper and brake line back into position. Fasten the caliper mounting bolts with a torque wrench or an air ratchet with an appropriate adapter. Replace the wheel assembly and tire.
Repeat this process for each additional rotor. When you're done, lower your accord, tighten and torque the tire lug nuts. Then refill the master cylinder with new brake fluid.
Pump the brake until you get a firm pedal and road test your Honda Accord to make sure that the new rotor installation was successful.
