Replace a single front brake rotor on a 2019-2024 Toyota RAV4 2.5L I4, including caliper bracket removal and proper torque specifications.

Warnings

Tools required

Parts

• Front brake rotor × 1 — 43512-42110 or equivalent OEM/aftermarket
• Rotor set screws (if corroded) × 2 — 90119-06062 or equivalent

Preparation

1. Park vehicle on level, solid ground and engage parking brake
2. Loosen front wheel lug nuts 1/4 turn while vehicle is on the ground
3. Lift front of vehicle with floor jack at designated jacking point
4. Support vehicle securely with jack stands under frame rails
5. Remove wheel and tire completely
6. Inspect brake system for any leaks, damaged hoses, or other issues 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 17mm socket or wrench, remove both slide pin bolts completely. These are located on the back side of the caliper and allow the caliper to slide on the bracket.
   Torque spec

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

   Remove and support brake caliper
   Carefully lift the brake caliper off the rotor and bracket. Do not disconnect the brake hose. Use wire, a bungee cord, or a hook to hang the caliper from the suspension strut or upper control arm. Ensure there is no tension on the brake hose and the caliper is secure.
   ⚠Never let the caliper hang by the brake hose. Damage to the hose can result in brake failure.
3. 3

   Remove caliper bracket bolts
   Locate the two large caliper bracket bolts that mount the bracket to the steering knuckle. These require a 19mm socket. Remove both bracket bolts completely and remove the entire caliper bracket assembly. These bolts are torqued very tight and may require significant force to loosen.
   Torque spec

   Caliper Bracket Bolts102 Nm (75 lb-ft)
4. 4

   Remove rotor set screws
   Locate the two Phillips head set screws on the face of the rotor. These screws retain the rotor to the hub during assembly. Using a Phillips screwdriver (impact driver recommended if screws are corroded), remove both set screws. If screws are stripped or severely corroded, they may need to be drilled out.
   ℹ️These screws are often corroded and difficult to remove. An impact screwdriver may be necessary. Replacement screws are inexpensive and recommended.

   Rotor Set Screws7 Nm (5 lb-ft)
5. 5

   Remove old brake rotor
   Pull the brake rotor straight off the wheel hub. If the rotor is stuck due to rust or corrosion, tap it gently with a rubber mallet from behind. Rotate the rotor and tap at different points around its circumference. Do not hit the rotor face or braking surface.
   ⚠Rotor may be heavy and have sharp edges. Use proper lifting technique and wear gloves.
6. 6

   Clean hub and inspect
   Clean the wheel hub mounting surface thoroughly with a wire brush to remove all rust, corrosion, and debris. The hub face must be clean and flat for proper rotor seating. Inspect the hub for damage, cracks, or excessive wear. Apply a thin coat of anti-seize compound to the hub face (avoid getting any on wheel studs).
   ℹ️Any debris or corrosion on the hub face can cause rotor runout and brake pulsation.
7. 7

   Install new brake rotor
   Remove any protective coating from the new rotor using brake parts cleaner. Clean both sides of the rotor thoroughly. Slide the new rotor onto the wheel hub, aligning the holes for the set screws. Ensure the rotor sits flush against the hub with no gaps or wobble.
   ℹ️New rotors have a protective oil coating that must be removed to prevent contamination and reduced braking performance.
8. 8

   Install rotor set screws
   Install the two rotor set screws and tighten to specification using a torque wrench or carefully by hand. These screws only need to hold the rotor in place during installation; the wheel and lug nuts provide the final clamping force. Do not overtighten.

   Rotor Set Screws7 Nm (5 lb-ft)
9. 9

   Reinstall caliper bracket
   Position the caliper bracket over the rotor and align the mounting holes with the steering knuckle. Apply threadlocker (medium strength, blue) to the caliper bracket bolt threads. Insert both bracket bolts and hand-tighten. Torque both bolts to specification in a crisscross pattern using a torque wrench.
   ⚠Caliper bracket bolts are critical safety components. Threadlocker is recommended and bolts must be torqued to exact specification.

10. 10

    Prepare and reinstall brake caliper
    If necessary, compress the caliper piston using a C-clamp or brake caliper tool to make room for the new rotor (which may be slightly thicker). Clean the caliper slide pins and apply a thin coat of silicone brake grease to the pins. Position the caliper over the rotor and bracket, aligning the slide pin bolt holes.
    ℹ️Compressing the caliper piston will push brake fluid back into the master cylinder reservoir. Check fluid level and remove excess if necessary to prevent overflow.
11. 11

    Install caliper slide pin bolts
    Apply silicone brake grease to the slide pin bolt threads and guide pins. Insert both caliper slide pin bolts and hand-tighten. Torque both bolts to specification using a torque wrench. Verify the caliper can slide freely on the pins.

12. 12

    Reinstall wheel and torque lug nuts
    Clean the wheel mounting surface on the rotor/hub. Mount the wheel onto the hub. Install all lug nuts and hand-tighten in a star pattern. Lower the vehicle until the tire just touches the ground (still partially supported). Torque lug nuts to specification in a star pattern using a torque wrench. Fully lower vehicle and remove jack stands.
    ⚠Improperly torqued lug nuts can cause wheel separation or brake rotor warping. Always use a star pattern and torque wrench.
    Torque spec

    Wheel Lug Nuts140 Nm (103 lb-ft)

Reassembly

1. Double-check that all fasteners have been properly installed and torqued to specification
2. Verify brake caliper is properly secured and brake hose is not kinked or under tension
3. Check brake fluid level in master cylinder reservoir and top off with DOT 3 brake fluid if necessary

Verification

• Before driving, pump the brake pedal several times until it feels firm. The pedal should not go to the floor
• Check brake fluid level one final time and inspect for any leaks around caliper and brake hose connections
• Perform a low-speed test drive in a safe area, testing brakes at 5-10 mph to verify proper operation
• Listen for any unusual noises such as grinding, squealing, or rubbing that might indicate improper installation
• Bed in new rotors according to manufacturer recommendations (typically involves 20-30 moderate stops from 30-40 mph without coming to complete stop, followed by cool-down period)
• Re-torque lug nuts after first 50-100 miles of driving
• If brake pedal feels soft, spongy, or travels too far, do not drive the vehicle and have the brake system inspected by a professional immediately
