Replace front brake rotors on a 2019-2024 Toyota RAV4 2.5L I4 FWD, including removal of calipers and brackets to access rotors.

Warnings

Tools required

Parts

• Front brake rotor (pair) × 2 — Use OEM specification or quality aftermarket
• Rotor set screws × 2 — 90116-04081 or equivalent

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level ground, place transmission in Park, and engage parking brake.
2. Place wheel chocks behind rear wheels.
3. Loosen front wheel lug nuts 1/4 turn while vehicle is on ground.
4. Lift front of vehicle with floor jack at designated front jacking point and secure on jack stands under frame rails.
5. Remove front wheels completely.
6. Open brake fluid reservoir cap to allow easier caliper piston compression (monitor fluid level throughout procedure).
7. Inspect brake fluid condition. If dark or contaminated, plan for complete fluid replacement.
8. Have silicone brake grease and threadlocker ready for reassembly.

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly (not the larger bracket bolts). Use a 17mm socket to remove both slide pin bolts. If bolts are seized, apply penetrating oil and wait 10-15 minutes before attempting removal.
   Torque spec

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

   Remove and support brake caliper
   Carefully lift the caliper assembly off the rotor. Do NOT allow the caliper to hang by the brake hose. Support the caliper using wire or a bungee cord attached to the suspension strut or other sturdy component. Ensure there is no tension on the brake hose.
   ⚠️Hanging calipers by the brake hose can cause internal hose damage leading to brake failure.
3. 3

   Inspect brake pads and caliper
   With caliper removed, inspect brake pad thickness on both inner and outer pads. If pads are less than 3mm thick, plan to replace them. Check caliper slide pins for corrosion or damage. This is an opportunity to service the slide pins if needed.
   ℹ️Replacing rotors with worn brake pads will result in poor braking performance and premature rotor wear.
4. 4

   Remove caliper bracket bolts
   Locate the two large caliper bracket bolts that secure the bracket to the steering knuckle. Use a 17mm or 19mm socket (depending on bolt head type) to remove both bracket bolts. These bolts are torqued to 120 Nm and may require significant force to loosen. Remove the entire bracket assembly.
   Torque spec

   Caliper Bracket Bolts102 Nm (75 lb-ft)
5. 5

   Remove rotor set screw and rotor
   Locate the Phillips head set screw on the face of the rotor (may be corroded). Use a Phillips screwdriver or impact driver to remove the set screw. If severely corroded, apply penetrating oil or use an impact driver. Once the set screw is removed, pull the rotor straight off the hub. If the rotor is stuck due to corrosion, tap it from behind with a rubber mallet while rotating it.
   ⚠Avoid striking the rotor face or hub threads with metal tools, as this can cause damage.
   Torque spec

   Rotor Set Screws7 Nm (5 lb-ft)
6. 6

   Clean hub surface
   Use a wire brush to clean the hub mounting surface where the rotor sits. Remove all rust, corrosion, and debris. The surface must be clean and flat to prevent rotor runout. Clean the wheel studs and inspect for damage. Apply a thin layer of anti-seize to the hub surface (avoiding the wheel studs).
   ℹ️Any debris or corrosion on the hub surface will cause rotor wobble and brake pulsation.
7. 7

   Prepare and install new rotor
   Remove the new rotor from packaging. Clean both sides of the new rotor with brake parts cleaner to remove the protective coating (this coating will cause brake noise and poor performance if not removed). Slide the new rotor onto the hub, ensuring it sits flat against the cleaned hub surface. Install a new rotor set screw and torque to specification.

8. 8

   Reinstall caliper bracket
   Position the caliper bracket onto the steering knuckle. Apply medium-strength threadlocker to the bracket bolt threads. Install both bracket bolts and torque to 120 Nm (88 lb-ft) in a crisscross pattern. Verify the bracket is secure and properly seated.
   ⚠Threadlocker is required on bracket bolts. Failure to use threadlocker may result in bolt loosening and brake failure.

9. 9

   Compress caliper piston
   Before reinstalling the caliper, the piston must be compressed to accommodate the new rotor thickness. Place a C-clamp or brake piston tool over the caliper with one side on the back of the caliper body and the other on the inner brake pad backing plate. Slowly compress the piston fully into the caliper bore. Monitor the brake fluid reservoir to ensure it does not overflow.
   ⚠If brake fluid overflows from the reservoir, remove excess fluid with a turkey baster or syringe. Do not allow fluid to spill on painted surfaces.
10. 10

    Service caliper slide pins
    Remove the slide pins from the caliper bracket. Clean the pins thoroughly with brake parts cleaner. Inspect the rubber boots for tears or damage. Apply a thin coat of silicone brake grease to the smooth portion of each slide pin (not the threaded portion). Reinstall the pins into the bracket boots.
    ℹ️Do not use petroleum-based grease on brake components. Use only silicone brake grease or manufacturer-specified lubricant.
11. 11

    Reinstall brake caliper
    Remove the caliper from its supported position. Guide the caliper over the new rotor and align it with the caliper bracket. Apply silicone brake grease to the threads of the slide pin bolts. Install both slide pin bolts and torque to 35 Nm (26 lb-ft).

12. 12

    Repeat for opposite side
    Perform steps 1-11 for the opposite front wheel to replace the second rotor. Ensure both sides are completed to the same specifications.
13. 13

    Reinstall wheels and lower vehicle
    Reinstall both front wheels, ensuring they are properly seated on the hub. Hand-tighten all lug nuts in a star pattern. Lower the vehicle until the wheels just touch the ground (but vehicle weight is still on jack stands). Torque lug nuts to 140 Nm (103 lb-ft) in a star pattern. Fully lower the vehicle and remove jack stands.

    Check brake fluid level and bed brakes
    Check the brake fluid reservoir and top off to the MAX line with fresh DOT 3 brake fluid if needed. Close the reservoir cap. Before driving, pump the brake pedal several times until it feels firm. The pedal should not go to the floor. Drive the vehicle in a safe area and perform 5-10 moderate stops from 30 mph to bed the new rotors to the brake pads.
    ⚠️Verify firm brake pedal before moving the vehicle. A soft or spongy pedal indicates air in the system or incomplete reassembly.
    ⚠New rotors require bedding. Avoid hard braking for the first 200 miles to allow proper pad transfer and prevent warping.

Reassembly

1. Ensure all fasteners are torqued to specification using a calibrated torque wrench.
2. Verify brake calipers move freely on slide pins without binding.
3. Confirm no brake hoses are twisted or under tension.
4. Double-check that wheel lug nuts are torqued in a star pattern.
5. After the first 50 miles of driving, re-torque wheel lug nuts to specification.

Verification

• Pump brake pedal multiple times. Pedal should be firm and consistent. If pedal is soft or goes to floor, DO NOT DRIVE and investigate immediately.
• Start vehicle and verify brake warning light is not illuminated on the dashboard.
• Perform a low-speed test stop (5-10 mph) in a safe area to verify brakes engage properly without noise or vibration.
• Check for any brake fluid leaks around caliper connections and brake lines.
• After bedding procedure, verify no brake pulsation, noise, or pulling to one side during normal braking.
• Within 50-100 miles, re-inspect all fasteners for proper torque and check for any signs of loosening or leaks.
