Brake Rotor - Rear Single

This procedure covers the replacement of a single rear brake rotor on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including caliper removal, rotor replacement, and proper torque specifications.

Warnings

Tools required

Parts

• Rear brake rotor × 1 — Use OEM specification or equivalent meeting Toyota specifications
• Rotor set screw (Phillips head) × 1 — Typically reusable unless damaged

Preparation

1. Park vehicle on level, solid ground and engage parking brake
2. Loosen rear wheel lug nuts 1/4 turn while vehicle is on the ground
3. Raise rear of vehicle with floor jack and secure with jack stands under manufacturer-designated lift points
4. Remove rear wheel completely
5. Inspect brake components for wear, damage, or fluid leaks before proceeding

Procedure

1. 1

   Compress brake caliper piston
   Before removing the caliper, compress the caliper piston to make removal easier and prevent brake fluid overflow at the master cylinder. Use a C-clamp or brake caliper piston tool to slowly compress the piston back into the caliper bore. Place the clamp on the back of the caliper body and against the outer brake pad. Compress slowly to allow fluid to return to the master cylinder.
2. 2

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper. These are 14mm bolts that secure the caliper to the bracket. Using a 14mm socket and ratchet, remove both caliper slide pin bolts. Keep these bolts as they will be reused.
   ⚠These bolts may have thread sealant applied. If difficult to remove, do not force; apply penetrating oil and wait.

   Caliper Slide Pin Bolts35 Nm (26 lb-ft)
3. 3

   Remove and support brake caliper
   Carefully lift the caliper off the brake rotor and bracket. Do NOT allow the caliper to hang by the rubber brake hose. Secure the caliper to the suspension or vehicle body using wire or a bungee cord, ensuring no tension is placed on the brake hose. Position the caliper where it will not interfere with rotor removal.
   ⚠️Never let the caliper hang by the brake hose. Damage to the hose can cause brake failure.
4. 4

   Remove caliper bracket bolts
   The caliper bracket is secured to the rear knuckle/hub assembly by two 17mm bolts. Using a 17mm socket or wrench, remove both caliper bracket bolts. These bolts may be tight and require significant force. Remove the bracket completely to access the rotor.
   ⚠Caliper bracket bolts are high-torque fasteners. Ensure proper socket engagement to avoid rounding.

5. 5

   Remove rotor set screw
   The rear rotor is typically secured by a Phillips head set screw on the face of the rotor hat. This screw may be corroded or tight. Use a Phillips screwdriver or impact driver to remove the set screw. If severely corroded, apply penetrating oil and allow to soak. Once removed, discard if damaged or retain for reinstallation.
   ⚠Set screw may be very tight or corroded. Use proper-sized screwdriver to avoid stripping.

6. 6

   Remove old brake rotor
   Once the set screw is removed, pull the rotor straight off the hub. The rotor may be stuck due to rust or corrosion between the rotor and hub face. If stuck, tap gently around the rotor face (not the braking surface) with a rubber mallet. Rotate the rotor and tap from multiple positions until it releases. Do not strike the braking surface or use excessive force that could damage the wheel bearing.
7. 7

   Clean hub mounting surface
   With the rotor removed, clean the hub face thoroughly using a wire brush and brake cleaner. Remove all rust, corrosion, and debris from the hub mounting surface and the wheel stud area. This ensures the new rotor will seat flat and true, preventing brake pulsation. Clean the hub pilot area where the rotor center bore contacts the hub.
   ℹ️A clean, flat hub surface is critical for proper rotor seating and smooth brake operation.
8. 8

   Install new brake rotor
   Remove any protective coating from the new rotor using brake cleaner and a clean cloth. Clean both sides of the rotor braking surface thoroughly. Slide the new rotor onto the hub, aligning the rotor center bore with the hub pilot. Ensure the rotor seats completely flat against the hub face. Install the rotor set screw and tighten to specification using a torque wrench.
   ⚠New rotors have a protective oil coating that must be completely removed before installation to ensure proper brake function.

   Reinstall caliper bracket
   Position the caliper bracket over the rotor and align the mounting holes with the rear knuckle/hub assembly. Install both 17mm caliper bracket bolts and hand-tighten. Using a torque wrench, tighten both bracket bolts to the specified torque in a cross pattern (alternate between bolts).
   ⚠️Caliper bracket bolts MUST be torqued to specification. Under-torquing can cause bracket loosening and catastrophic brake failure.

    Reinstall brake caliper
    Remove the caliper from its temporary support position. Ensure the brake pads are properly positioned in the caliper bracket. Carefully lower the caliper over the rotor and align the caliper slide pin bolt holes with the bracket pins. Apply a small amount of silicone brake grease to the slide pin bolt threads if recommended. Install both caliper slide pin bolts and hand-tighten, then torque to specification.
    ℹ️Ensure brake pads are correctly seated in the bracket before installing caliper.

    Reinstall wheel and lower vehicle
    Clean the wheel hub contact surface and reinstall the wheel. Thread all lug nuts by hand to prevent cross-threading. Snug the lug nuts in a star pattern using a lug wrench. Lower the vehicle from the jack stands until the tire just contacts the ground (weight still on stands). Torque the lug nuts to specification in a star pattern. Fully lower the vehicle and remove jack stands.
    ⚠️Wheel lug nuts must be torqued in a star pattern to ensure even clamping force and prevent wheel detachment.

    Restore brake pedal pressure
    Before moving the vehicle, sit in the driver's seat and pump the brake pedal slowly and firmly several times until you feel normal, firm pedal resistance. This repositions the caliper piston against the new rotor and restores proper brake system pressure. The pedal should feel firm. If the pedal feels soft or goes to the floor, do not drive the vehicle and investigate for problems.
    ⚠️DO NOT move the vehicle until proper brake pedal pressure is restored. A soft pedal indicates a problem that must be corrected.

Reassembly

1. All fasteners must be torqued to the exact specifications listed using a calibrated torque wrench
2. Brake rotors should be replaced in pairs (both rear rotors) for balanced braking performance
3. After reassembly, verify parking brake operation functions normally
4. New brake rotors require a proper break-in procedure for optimal performance

Verification

• Pump brake pedal several times with engine off - pedal should be firm and hold pressure
• Start engine and verify brake pedal does not sink when pressure is applied
• Perform a low-speed test drive in a safe area, checking for normal brake operation, no pulling, and no unusual noises
• Check for fluid leaks around caliper and brake hose connections
• Verify wheel lug nuts remain tight after test drive (re-check torque after 50-100 miles)
• Break in new rotors following manufacturer recommendations: 30-40 moderate stops from 30-40 mph with cooling periods between stops, avoiding hard braking for first 200 miles
