Replace rear brake pads on a 2019-2024 Toyota RAV4 2.5L I4, including caliper service and proper bedding procedure.

Warnings

Tools required

Parts

• Rear brake pad set (left and right) × 1 — Use OEM specification or equivalent ceramic/semi-metallic pads
• Brake pad hardware/shim kit × 1 — Often included with pad set

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground and engage parking brake firmly
2. Place wheel chocks in front of both front wheels
3. Remove approximately 1/3 of brake fluid from master cylinder reservoir using turkey baster or pump. Store in sealed container. This prevents overflow when compressing pistons
4. Loosen rear wheel lug nuts 1/4 turn while vehicle is on ground (do not remove)
5. Lift rear of vehicle with floor jack at designated rear jacking point and secure with jack stands under frame rails
6. Remove rear wheels completely and set aside in safe location

Procedure

1. 1

   Inspect brake system condition
   Before beginning disassembly, inspect the brake rotors for deep grooves, cracks, or excessive wear. Check brake hoses for cracks, bulges, or fluid leakage. Inspect caliper slide pins for torn rubber boots. If rotors are damaged or measure below minimum thickness (stamped on rotor), they must be replaced. Document rotor condition before proceeding.
2. 2

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the inboard side of the caliper. Use a 17mm socket to remove the lower slide pin bolt completely. Remove the upper slide pin bolt. Support the caliper with one hand as you remove the second bolt to prevent it from falling. The RAV4 uses a sliding caliper design where the entire caliper pivots off once both bolts are removed.
3. 3

   Remove caliper and secure
   Carefully lift the caliper assembly off the brake rotor and bracket. Do not let the caliper hang by the brake hose, as this can damage the hose internally. Suspend the caliper from the suspension or chassis using a wire hanger, bungee cord, or zip ties. Position it so there is no tension or stress on the brake hose.
   ⚠Never let brake calipers hang by the brake hose. Internal hose damage can cause brake failure.
4. 4

   Remove old brake pads and hardware
   Remove the two brake pads from the caliper bracket. They may be held by spring clips or simply sitting in the bracket. Note the orientation of any anti-rattle shims or clips attached to the pads. Remove all pad hardware, springs, and shims from the bracket. Take photos if needed to document the original configuration for reassembly.
5. 5

   Clean caliper bracket and slides
   Spray the caliper bracket thoroughly with brake cleaner to remove all brake dust, dirt, and old grease. Use a wire brush to clean the pad slide surfaces on the bracket where the pads make contact. Clean the caliper slide pin bores in the bracket. Inspect the bracket for cracks or damage. Wipe everything clean with rags.
6. 6

   Inspect and lubricate slide pins
   Remove both caliper slide pins from the bracket (if not already removed). Inspect the rubber boots for tears or damage - replace if compromised. Clean the pins completely with brake cleaner. Apply a thin, even coat of silicone brake grease to the entire length of each slide pin (do not use petroleum-based grease). Reinstall pins into the bracket and ensure they slide smoothly. Verify the rubber boots are properly seated.
7. 7

   Compress caliper pistons
   Place the caliper on a workbench with the pistons facing up. If you did not remove sufficient brake fluid from the reservoir in preparation, do so now. Use a brake caliper compression tool or large C-clamp to slowly and evenly compress both pistons fully into the caliper bore. The pistons should compress flush with the caliper housing. Wipe away any brake fluid that seeps out. Check the master cylinder reservoir to ensure it has not overflowed.
   ⚠️Compressing pistons forces brake fluid back into the system. If reservoir overflows, brake fluid will damage painted surfaces and wiring.
8. 8

   Install new pad hardware and shims
   Install the new brake pad hardware kit onto the caliper bracket exactly as the old hardware was positioned. This typically includes spring clips on the bracket slide surfaces. Apply a thin layer of silicone brake grease to the metal backing plates of the new brake pads where they contact the bracket (do not get grease on friction material). Attach any anti-rattle shims to the new pads according to manufacturer instructions.
9. 9

   Install new brake pads
   Install the new brake pads into the caliper bracket. The inner pad (with piston contact) and outer pad may be different sizes - verify correct positioning. The friction material should face the rotor. The pads should fit snugly in the bracket but slide freely in the hardware clips. Ensure any wear indicators (squealer tabs) are positioned correctly, typically on the inner pad facing upward.
10. 10

    Reinstall caliper assembly
    Remove the caliper from its secured position and carefully position it over the new brake pads and rotor. Align the caliper slide pin bolt holes with the slide pins in the bracket. You may need to slightly compress or adjust the pads to fit the caliper over them. Ensure the caliper sits flush against the bracket with no binding.
11. 11

    Install and torque slide pin bolts
    Apply a thin coat of silicone brake grease to the threads and under the bolt heads of both caliper slide pin bolts. Insert both bolts and hand-tighten. Using a torque wrench, torque both slide pin bolts to specification in a cross pattern. Verify the caliper moves freely on the slide pins after torquing by attempting to slide it slightly - it should have minimal resistance.

    Repeat for opposite side
    Perform all previous steps (steps 1-11) on the opposite rear brake assembly. It is critical to replace brake pads on both sides of the same axle simultaneously to maintain balanced braking performance. Never replace pads on only one side.
    ⚠️Always replace brake pads on both sides of an axle. Uneven braking can cause vehicle instability and loss of control.
13. 13

    Reinstall wheels
    Clean the wheel hub face and wheel mounting surface with a wire brush. Install the rear wheels and hand-tighten all lug nuts in a star pattern. Lower the vehicle until the wheels just contact the ground but most weight is still on the jack stands. Torque the lug nuts to specification in a star pattern using a torque wrench. Fully lower the vehicle and remove jack stands. Verify final lug nut torque with wheels on ground.

    Wheel Lug Nuts140 Nm (103 lb-ft)
14. 14

    Restore brake pedal and check fluid
    Before moving the vehicle, pump the brake pedal slowly and firmly 10-15 times until it feels firm and normal. The first few pumps will feel soft as the caliper pistons extend to contact the new pads. Check the master cylinder reservoir and add DOT 3 brake fluid to the MAX line if needed. Inspect under the vehicle for any fluid leaks around calipers and brake hoses.
    ⚠️Do not attempt to move the vehicle until brake pedal feels firm and normal. Failure to pump pedal will result in no braking ability.
15. 15

    Perform brake bed-in procedure
    New brake pads must be properly bedded to achieve full braking performance. Find a safe, empty road or parking lot. Perform 8-10 moderate stops from 40 mph to 10 mph with 30-second cool-down periods between stops. Then perform 3-4 harder stops from 50 mph to 10 mph (not full emergency stops). Allow brakes to cool for 10 minutes without coming to a complete stop if possible. This transfers an even layer of pad material to the rotor surface.
    ⚠Perform bed-in procedure in safe area away from traffic. Brakes will not achieve full performance until properly bedded.

Reassembly

1. Torque specifications must be followed exactly - improper torque on caliper bolts can cause brake failure
2. Only use silicone-based brake grease on brake components - never use petroleum-based lubricants
3. Verify brake pedal is firm before test driving - if pedal feels spongy after bedding, system may require bleeding
4. Check brake fluid level after 50 miles and top off if needed as pads seat

Verification

• Brake pedal should feel firm and normal with no excessive travel or sponginess
• No brake fluid leaks visible around calipers, hoses, or master cylinder
• No unusual noises during light brake application (squealing may occur until fully bedded)
• Vehicle should brake in a straight line with no pulling to either side
• All wheel lug nuts should be torqued correctly - re-check after 50 miles
• Test brakes at low speed in safe area before returning to normal driving
• After 200-300 miles of break-in, braking performance should be fully restored
