Brake Rotor - Rear Single

This procedure covers removal and replacement of a single rear brake rotor on a 2018-2024 Toyota Camry with the 2.5L I4 engine, including caliper removal and proper torque specifications.

Warnings

Tools required

Parts

• Rear brake rotor × 1 — Use OEM specification or quality aftermarket equivalent
• Rotor set screw (if corroded) × 1 — M6x1.0 Phillips set screw

Preparation

1. Park vehicle on level, solid surface and engage parking brake firmly
2. Shift transmission to Park (automatic) or 1st gear (manual)
3. Loosen rear wheel lug nuts 1/4 turn while vehicle is still on ground
4. Raise rear of vehicle with floor jack at designated jacking points per owner's manual
5. Support vehicle securely on jack stands rated for vehicle weight
6. Remove rear wheel completely and set aside
7. Visually inspect brake caliper, bracket, and hose for damage or leaks before proceeding

Procedure

1. 1

   Compress brake caliper piston
   Before removing the caliper, use a C-clamp or brake piston tool to slowly compress the caliper piston back into its bore. Place the clamp against the back of the caliper body and the outer brake pad. This creates clearance for caliper removal and prevents brake fluid overflow at the master cylinder reservoir. Compress slowly and evenly.
2. 2

   Remove caliper slide pin bolts
   Using a 14mm socket or wrench, remove the two caliper slide pin bolts that secure the caliper to the bracket. These bolts are located on the inboard side of the caliper assembly. Keep these bolts together and inspect them for damage or excessive wear. Note the position of any washers or sleeves.
   ⚠These bolts have silicone brake grease applied. They will be re-greased during reassembly.

3. 3

   Remove and secure brake caliper
   Carefully lift the caliper off the bracket and rotor. Do NOT let it hang by the brake hose. Use wire, a bungee cord, or rest it on a suspension component to support the caliper weight. Inspect the caliper and brake hose for any signs of leaking, cracking, or damage. The brake pads may come off with the caliper or remain in the bracket.
   ⚠️Allowing the caliper to hang by the brake hose can cause internal hose damage and eventual brake failure.
4. 4

   Remove caliper bracket bolts
   Using a 17mm socket or wrench, remove the two caliper bracket bolts that secure the bracket to the steering knuckle/hub assembly. These bolts are torqued to a high specification and may require significant force to break loose. Use a breaker bar if necessary. Remove the bracket completely and set aside with its bolts.
   ⚠These bolts are high-torque fasteners. Ensure your tools are properly seated to avoid rounding the bolt heads.

5. 5

   Remove rotor set screw
   Locate the Phillips set screw on the face of the rotor (if equipped). Use a Phillips screwdriver or impact driver to remove this screw. These screws are often corroded and may be difficult to remove. If the screw strips or breaks, it can be left in place or drilled out, as it is only used for assembly alignment and is not required for safe operation.
   ℹ️Some rotors may not have a set screw. The set screw is for assembly convenience only and is not structurally critical.

6. 6

   Remove old brake rotor
   Pull the rotor straight off the hub. If the rotor is stuck due to rust or corrosion, tap it from behind with a rubber mallet, alternating positions around the rotor. Do NOT use excessive force that could damage wheel studs or the hub bearing. If severely stuck, apply penetrating oil to the hub-rotor interface and allow it to soak. Clean the hub face thoroughly with a wire brush and brake parts cleaner, removing all rust, scale, and debris.
   ⚠Never strike the rotor with a steel hammer directly on the friction surface or hat, as this can cause cracking. Use a rubber mallet on the back side between the studs.
7. 7

   Prepare hub and install new rotor
   Ensure the hub mounting surface is completely clean and free of rust, dirt, and old adhesive. Apply a thin coating of anti-seize compound to the hub face (not the rotor friction surfaces). Remove any protective coating from the new rotor using brake parts cleaner. Slide the new rotor onto the hub, ensuring it seats flush against the hub face. Install the rotor set screw (if equipped) and hand-tighten.
   ⚠New rotors often have a protective oil coating. Clean both friction surfaces completely with brake parts cleaner before installation.
8. 8

   Torque rotor set screw
   Using a Phillips screwdriver or torque-limiting tool, torque the rotor set screw to specification. Do not overtighten, as this screw threads into the hub and is only for assembly alignment. Cross-threading or overtightening can damage the hub threads.

9. 9

   Reinstall caliper bracket
   Position the caliper bracket onto the steering knuckle mounting surface. Install both bracket bolts and hand-thread them to ensure proper engagement. Using a torque wrench and 17mm socket, torque both caliper bracket bolts to specification in an alternating pattern to ensure even seating.
   ⚠️Caliper bracket bolts are critical safety fasteners. Verify proper torque with a calibrated torque wrench.

    Prepare and reinstall caliper
    If brake pads were removed, reinstall them in the bracket with anti-squeal shims in their original positions. Apply a thin layer of silicone brake grease to the caliper slide pin bolt threads and smooth sliding portions. Position the caliper over the rotor and bracket, aligning the slide pin bolt holes. Install both slide pin bolts and hand-thread them.
    ℹ️Use only silicone brake grease on slide pins. Do not use petroleum-based grease, which can damage rubber components.
11. 11

    Torque caliper slide pin bolts
    Using a torque wrench and 14mm socket, torque both caliper slide pin bolts to specification. Ensure the caliper moves freely on the slide pins after torquing. The caliper should slide smoothly when pushed by hand.
    ⚠️Improperly torqued slide pin bolts can cause uneven brake pad wear or caliper seizure, leading to brake failure.

12. 12

    Reinstall wheel and torque lug nuts
    Position the wheel onto the hub and hand-thread all lug nuts. Using a torque wrench, torque the lug nuts to specification in a star pattern (cross pattern) to ensure even seating. Lower the vehicle slightly so the wheel contacts the ground but still has most weight on jack stands, then perform final torque in star pattern. Fully lower vehicle and remove jack stands.
    ⚠️Improper lug nut torque can cause wheel separation. Always use a star pattern and calibrated torque wrench.

    Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

1. Ensure all caliper and bracket bolts are torqued to proper specifications using a calibrated torque wrench
2. Verify the caliper slides freely on its pins and there is no binding or interference
3. Double-check that wheel lug nuts are torqued in a star pattern to specification
4. Silicone brake grease must be applied to slide pin bolts per torque specifications

Verification

• Before moving vehicle, pump the brake pedal several times until it becomes firm. The pedal should not go to the floor.
• Check brake fluid level in master cylinder reservoir. Top off with DOT 3 brake fluid if needed (fluid may have dropped when piston was compressed).
• Start the engine and verify the brake warning light is not illuminated on the dashboard.
• Perform a low-speed brake test in a safe area. The vehicle should brake smoothly without pulling to one side.
• After 25-50 miles of normal driving, re-torque wheel lug nuts to specification to ensure they remain properly seated.
• Bed in new rotors according to manufacturer recommendations (typically 10-15 gentle stops from 30-40 mph without coming to complete stop, followed by cool-down period).
• If you replaced only one rear rotor, monitor for any brake pull or vibration. Rotors should ideally be replaced in axle pairs for balanced braking.
