Rotors rarely need to be replaced, but if your Acura Integra is shuddering and pulsing when you hit the brakes then your rotors are probably warped or worn down and it's time to buy new ones. If you are comfortable working on your own vehicle, replacing the rotors yourself is a cost effective alternative to sending it to the shop.
Buy a new pair of rotors for your Acura Integra at your local auto parts store or online. Plan on swapping out all four rotors at once, or at least the front or rear pair. Never replace just one rotor, as this leads to uneven and very unsafe braking.
Drain half of the brake fluid from the master cylinder using a siphon. This relieves the pressure in the brake line. Then get your Integra off the ground by jacking up the vehicle and then using jack stands to support it. Make sure the Acura is parked on level ground before you start working.
Remove the tire and wheel assembly by using a socket wrench to undo the lug nuts. Undo the caliper mounting bolts with a socket wrench and move the caliper away from the rotor. Use mechanic's wire to suspend the caliper to prevent any damage to the brake line. Next, remove the rotor retaining screws.
Pull off the old rotor and clean the area with a damp cloth to remove any rust or debris. Dust or corrosion can contain asbestos, so exercise caution while cleaning the area.
Install the new rotor by lining it up on the wheel hub. Make sure that the mounting screws and any threaded area is dry before installing it. Secure the mounting screws into place.
Replace the caliper and mounting bolts with a torque wrench. Be sure to remove the mechanic's wire before replacing the tire and wheel assembly.
Put the wheel assembly and tire back on. Once all four tires and rotors have been replaced, add new brake fluid. Bleed the brakes if necessary. Lower the car and then tighten the lug nuts on each wheel properly using a torque wrench or an air ratchet with an appropriate adapter.
