This procedure covers cleaning, inspecting, and lubricating the brake caliper slide pins to ensure proper caliper movement and even brake pad wear.

Warnings

Tools required

Parts

• Silicone brake grease packet × 1 — Use high-temperature silicone brake lubricant
• Brake cleaner aerosol × 1 — Non-chlorinated brake parts cleaner

Preparation

1. Park vehicle on level, solid ground and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen wheel lug nuts 1/4 turn while vehicle is on ground
4. Raise front of vehicle with floor jack at manufacturer-specified lift points
5. Support vehicle securely on jack stands rated for vehicle weight
6. Remove front wheel completely
7. Verify caliper type: 2019-2024 RAV4 2.5L FWD uses single-piston floating calipers with two slide pins

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly. These are 14mm bolts with rubber boots covering the slide pins. Remove both caliper slide pin bolts completely using a 14mm socket or wrench. Keep track of which bolt came from the upper and lower positions.

2. 2

   Pivot caliper upward
   Carefully pivot the caliper upward away from the rotor and brake pads. The caliper will remain attached to the brake hose - do not let it hang by the hose. Support the caliper using a bungee cord, wire, or rest it on the suspension component to avoid stressing the brake line.
3. 3

   Remove slide pins from bracket
   Pull back the rubber dust boots on the caliper bracket. Extract both slide pins from the bracket by pulling them straight out. The pins should slide out with minimal resistance. If pins are seized or require excessive force, note the location for potential bracket replacement.
   ⚠Seized slide pins indicate corrosion damage. If pins cannot be removed or show pitting/scoring, the caliper bracket assembly should be replaced.
4. 4

   Inspect slide pins and boots
   Thoroughly inspect both slide pins for scoring, pitting, corrosion, or damage. Inspect rubber dust boots for tears, cracks, or deterioration. Check that boots still have elasticity and are not hardened. Inspect the bracket bores where the pins slide for corrosion or damage. Replace any damaged components before proceeding.
   ⚠️Damaged slide pins or boots will cause uneven braking and premature pad wear. Replace any questionable parts - do not attempt to reuse damaged components.
5. 5

   Clean slide pins and bracket bores
   Using clean shop rags and brake cleaner, thoroughly clean both slide pins to remove all old grease and contamination. Clean the caliper bracket bores where the pins slide using brake cleaner and shop rags. Use a wire brush if necessary to remove corrosion from bracket bores, then clean again with brake cleaner. Ensure all surfaces are completely clean and dry before lubrication.
6. 6

   Apply silicone brake grease to slide pins
   Apply a thin, even coat of high-temperature silicone brake grease to the entire length of both slide pins, focusing on the sliding surface area. Do not use petroleum-based grease or excessive amounts of lubricant. The coating should be thin enough that the pin surface is visible through the grease.
   ⚠Only use silicone-based brake grease. Petroleum-based products will damage rubber boots and cause premature failure.
7. 7

   Reinstall slide pins
   Insert the lubricated slide pins back into the caliper bracket bores, ensuring they slide smoothly with minimal resistance. Push pins in fully until they bottom out in the bracket. Position the rubber dust boots over the pins and bracket to seal properly. Verify pins move freely in and out of the bracket by hand.
8. 8

   Reposition caliper and brake pads
   Inspect brake pads for uneven wear patterns that may indicate previous slide pin problems. If replacing pads, install new pads now. If reusing pads, ensure they are properly seated in the bracket. Lower the caliper back down over the brake pads and rotor, ensuring it seats flush against the slide pins.
9. 9

   Install and torque caliper slide pin bolts
   Thread both caliper slide pin bolts by hand to avoid cross-threading. Once hand-tight, torque both bolts to 35 Nm (26 lb-ft) using a torque wrench. Verify bolts are fully seated and dust boots are not pinched or damaged during installation.

10. 10

    Verify caliper movement
    With the caliper fully installed, use a pry bar or large screwdriver to carefully push the caliper side-to-side on the slide pins. The caliper should move smoothly without binding. This floating action is essential for even brake pad contact. If binding is detected, remove caliper and inspect for proper lubrication and pin installation.
    ⚠️Binding calipers will cause uneven braking, reduced stopping power, and potential brake failure. Do not operate vehicle if caliper does not move freely on slide pins.
11. 11

    Reinstall wheel and torque lug nuts
    Place wheel onto hub and thread all lug nuts by hand. Tighten lug nuts in a star pattern to seat the wheel, then lower vehicle until tire just touches ground. Torque all lug nuts to 140 Nm (103 lb-ft) in a star pattern using a torque wrench.

    Repeat for remaining wheels
    Raise vehicle again, remove jack stand, and repeat the entire procedure for the remaining front wheel. For rear brakes (if servicing), follow the same procedure as rear calipers use identical slide pin design on this vehicle. Always complete one wheel entirely before starting another.

Reassembly

1. Ensure all caliper slide pin bolts are torqued to specification and dust boots are properly seated
2. Verify all wheels are installed and lug nuts are torqued in star pattern
3. Lower vehicle completely and remove jack stands
4. Double-check all lug nuts at final torque specification with vehicle on ground

Verification

• Pump brake pedal several times until firm pedal is achieved before moving vehicle
• Start engine and verify brake pedal remains firm with steady pressure
• Test brakes at low speed (under 10 mph) in a safe area to verify proper operation and even braking
• Drive vehicle and verify no brake noise, vibration, or pulling to one side during braking
• After first 50-100 miles, re-check wheel lug nut torque
• Inspect for brake fluid leaks around caliper and brake line connections
• Monitor brake performance for several days - any unusual noise, vibration, or pulling requires immediate inspection
