The Toyota Camry debuted in 1983 and began a long-standing rivalry with the Honda Accord. The 1993 Toyota Camry was equipped with a 130-horsepower 2.2-liter, inline four-cylinder engine in the base model. A stronger 185-horsepower V-6 was optional for all four sub-models, the DX, LX, SE and XLE. The 1993 Camry was available with optional four-wheel disc brakes. Replacing the rear rotors on the 1993 Camry is similar to replacing the front rotors, with the exception of the internal parking brake shoe inside the rear rotor.
Raise the hood of the Camry and set the hood prop. Remove brake fluid from the fluid reservoir with a turkey baster or bottle siphon, until the fluid level is about 1/2 inch below the "Full" mark. Install the reservoir lid and lock it in place.2
Loosen the rear wheel lug nuts on the Camry with a tire iron. Raise the rear of the car with a jack. Place jack stands beneath the rear axle beam, about 6 inches inward from the rear wheels. Lower the Camry on the stands. Remove the lug nuts completely from the car, then remove the rear wheels.3
Remove the brake-line support clip from the rear strut on one side of the car, with a ratchet and socket. Install an open-end wrench onto the caliper guide pin, between the rear of the caliper and the caliper bracket. Hold the guide pin still while removing the caliper bolt with a ratchet and socket. Repeat this step to remove the second caliper bolt. Remove the caliper from the brake assembly, using a small pry bar if necessary. Hang the caliper from the rear strut spring with a metal clothes hanger or hook.4
Remove the old brake pads from the caliper-mounting bracket by hand. Insert one of the old pads against the piston on the inside of the rear caliper. Wrap a C-clamp around the old brake pad and the rear of the caliper. Tighten the C-clamp slowly, until the caliper piston completely compresses in the caliper bore. Remove the C-clamp and the old brake pad, then discard your old brake pads.5
Remove the caliper-mounting bracket with a ratchet and socket. Remove the rear brake rotor by hand. If the rotor is hard to remove, hit the rotor from side to side on the raised sides with a rubber mallet. This will release the brake rotor from the parking brake shoe, located inside the rotor. Tap the rotor on the inboard side outward, if necessary, to remove the rotor.6
Inspect the parking brake shoe. If the shoe is less than 1/16-inch thick or worn down to the bare metal, replace the parking brake shoe. Spray the internal components of the parking brake shoe assembly thoroughly using aerosol brake cleaner.7
Install the new brake rotor onto the hub assembly. Install two wheel lug nuts with your fingers and tighten them to the face of the rotor. This will hold the rotor in place for installation of the remaining brake components. Thoroughly spray the new rotor on both sides with brake cleaner to remove the anti-rust oil applied at the factory. Use about half of the can for one rotor. Install the caliper-mounting bracket and tighten the bolts to 34 foot-pounds with a 1/2-inch-drive torque wrench and socket.8
Install new brake pads onto the caliper-mounting bracket. Insert the pad with the metal U-shaped clip on the inboard side of the rotor, so the clip faces upward. Lubricate the outer shim plates on both new pads lightly with caliper grease.9
Pull the caliper guide pins by hand from the rear of the hanging caliper. Lubricate the pins thoroughly with caliper grease, then install them back into the caliper. Remove the caliper from the hanger and set the caliper onto the brake assembly. Install and tighten the caliper bolts to 14 foot-pounds with the torque wrench and a socket. Hold the caliper guide pins with an open-end wrench while you torque the caliper bolts. Install the brake-line bracket onto the strut, and tighten mounting bolt to 21 foot-pounds.10
Repeat steps 2 through 9 to complete the rear rotor replacement on the second side of the Camry. Install the rear wheels and tighten the lug nuts snug with a tire iron. Raise the car off the jack stands, then remove the stands from beneath the car. Lower the Camry to the ground and tighten the rear lug nuts to 80 foot-pounds with the torque wrench and a wheel-nut socket.11
Check and fill the brake fluid reservoir once the car rests on the ground. Install the reservoir lid and tighten it. Sit in the driver's side of the Camry and depress the brake pedal slowly about 2/3 of the way to the floor, then release the pedal to its upright position. Depress the pedal again and release it. If the pedal does not stiffen after three pumps, stop pumping and bleed the rear brakes.
