Brake Rotors - Rear Pair

This procedure replaces both rear brake rotors on a 2018-2024 Toyota Camry with 2.5L I4 engine, requiring caliper bracket removal and proper torque specifications.

Warnings

Tools required

Parts

• Rear brake rotor × 2 — Use OEM specification or equivalent meeting Toyota standards
• Rotor set screws (if corroded) × 2 — M6 x 1.0 thread pitch

Preparation

1. Park vehicle on level, solid ground. Engage parking brake firmly.
2. Place wheel chocks in front of the front wheels.
3. Loosen rear wheel lug nuts 1/4 turn while vehicle is on the ground, but do not remove.
4. Lift rear of vehicle using floor jack at designated rear jacking point per owner's manual.
5. Place jack stands under rear subframe or designated lift points. Lower vehicle onto stands.
6. Remove rear wheels completely and set aside.
7. Inspect brake system for any fluid leaks, damaged hoses, or worn components before proceeding.

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly. Using a 14mm socket or wrench, remove both slide pin bolts completely. The caliper can now pivot or be removed from the bracket.

   Caliper Slide Pin Bolts35 Nm (26 lb-ft)
2. 2

   Support and compress caliper
   Carefully lift the caliper assembly off the rotor and brake pads. Support the caliper using wire or a bungee cord attached to the suspension or body—never let it hang by the brake hose. Before fully removing, use a C-clamp or caliper piston tool to slowly compress the caliper piston back into the bore. This makes room for the new rotor and prevents brake fluid overflow from the master cylinder reservoir.
   ⚠️Do not let caliper hang by brake hose. Secure it with wire or bungee cord to prevent hose damage.
3. 3

   Remove caliper bracket
   Locate the two caliper bracket bolts (also called caliper mounting bolts) that secure the bracket to the rear spindle/knuckle. These are typically 17mm bolts behind the bracket. Use a breaker bar or impact wrench if necessary, as these bolts are torqued to 102 Nm (75 lb-ft). Remove both bolts and remove the entire caliper bracket assembly. Keep track of brake pads if reusing.

4. 4

   Remove old rotor
   Remove the rotor set screw(s) from the face of the rotor using a Phillips or JIS screwdriver. If corroded, use penetrating oil and allow to soak, or carefully drill out if necessary. Pull the rotor off the hub. If rotor is seized, use a rubber mallet to tap around the edges and back face (never strike the friction surface). For stubborn rotors, thread M8 bolts into the threaded holes (if present) to push the rotor off the hub.
   ⚠Do not strike the rotor friction surface with metal tools. This can cause damage that affects braking performance.

   Prepare hub surface
   Use a wire brush to clean the hub mounting surface, removing all rust, corrosion, and debris. The hub face must be clean and flat for proper rotor seating. Clean the wheel studs and inspect for damage. Apply a thin layer of anti-seize compound to the hub face (avoiding the wheel stud threads) to prevent future rotor seizing.
   ℹ️Any debris or corrosion between hub and rotor will cause rotor runout and brake pulsation.
6. 6

   Install new rotor
   Remove any protective coating from the new rotor using brake cleaner and wipe clean. Place the new rotor onto the hub, ensuring it sits flat against the hub face. Install new or cleaned rotor set screw(s) and tighten to 7 Nm (5 lb-ft) using a torque wrench. These screws only hold the rotor during assembly; the wheel provides clamping force during operation.

7. 7

   Reinstall caliper bracket
   Position the caliper bracket back onto the spindle/knuckle. Apply medium-strength thread locker to the caliper bracket bolt threads. Install both caliper bracket bolts and tighten them in a crisscross pattern to 102 Nm (75 lb-ft) using a torque wrench. Ensure bracket is seated properly before final torquing.
   ⚠Thread locker prevents bracket bolts from loosening under vibration. Failure to use thread locker may result in brake failure.

   Install brake pads and caliper
   If brake pads were removed, reinstall them into the caliper bracket with anti-rattle clips in their correct positions. Remove the caliper from its temporary support. Position the caliper over the brake pads and rotor. Clean the slide pin bolt threads and apply silicone brake grease to the smooth portion of the slide pins (not the threads). Install both slide pin bolts and torque to 35 Nm (26 lb-ft).
   ℹ️Silicone brake grease on slide pins ensures proper caliper movement and even pad wear. Do not use petroleum-based grease.

   Repeat for opposite side
   Perform steps 1 through 8 on the opposite rear wheel to replace the second rotor. Both rear rotors should always be replaced as a pair to ensure balanced braking performance.
   ⚠Always replace rotors in axle pairs. Replacing only one rotor causes uneven braking and vehicle pull.
10. 10

    Reinstall wheels and lower vehicle
    Reinstall both rear wheels, threading lug nuts on by hand first. Tighten lug nuts in a star pattern snugly using a wrench, but do not fully torque yet. Raise vehicle slightly off jack stands using floor jack, remove jack stands, and carefully lower vehicle to the ground. With vehicle weight on wheels, torque all lug nuts in a star pattern to 140 Nm (103 lb-ft).
    ⚠Always torque lug nuts in a star pattern to ensure even wheel seating and prevent warping.

    Pump brake pedal and verify operation
    Before moving vehicle, sit in driver's seat and pump brake pedal several times until it becomes firm. This repositions the caliper pistons against the new rotors. Check brake fluid level in master cylinder reservoir and top off with DOT 3 brake fluid if necessary (fluid level drops as pistons compress). Verify pedal feels firm and normal.
    ⚠️Do not attempt to drive vehicle until brake pedal is firm. A soft pedal indicates air in system or improper assembly.

Reassembly

1. Torque all fasteners to specified values using a calibrated torque wrench.
2. Ensure wheel lug nuts are torqued in star pattern to 140 Nm (103 lb-ft).
3. After first 50 miles of driving, re-torque wheel lug nuts to specification to ensure proper seating.

Verification

• Pump brake pedal multiple times—pedal should feel firm and consistent within 3-4 pumps.
• Verify brake fluid level is within MIN/MAX marks on master cylinder reservoir.
• Test brakes at low speed (5-10 mph) in a safe area before returning to normal driving.
• Listen for any unusual noises—light squealing during initial break-in is normal, grinding or rubbing is not.
• Check for any brake fluid leaks around calipers, hoses, and connections.
• Verify no brake warning lights are illuminated on instrument cluster.
• Perform bed-in procedure: 8-10 moderate stops from 40 mph to 10 mph with 30 seconds between stops, allowing brakes to cool fully before aggressive use.
• After 100-200 miles, verify no vibration or pulsation during braking and that vehicle stops straight without pulling.
