This procedure covers removal and replacement of the front brake caliper bracket on a 2019-2024 Toyota RAV4 2.5L I4, including caliper removal, bracket replacement, and brake system verification.

Warnings

Tools required

Parts

• Brake caliper bracket (specify front left or right) × 1 — Use OEM specification
• Brake pad hardware/anti-rattle clips × 1 — Usually included with bracket or pads
• Brake pads (if worn or contaminated) × 1 — Use OEM specification

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground and engage parking brake firmly
2. Chock rear wheels securely on both sides
3. Using turkey baster, remove approximately 1/3 of brake fluid from master cylinder reservoir to prevent overflow when compressing caliper piston
4. Loosen front wheel lug nuts 1/4 turn while vehicle is on ground
5. Lift front of vehicle with floor jack at designated front jacking point (subframe reinforcement behind front cross-member)
6. Place jack stands under designated front lift points on pinch weld rails and lower vehicle onto stands
7. Remove front wheel completely
8. Inspect brake system for leaks, damage, or abnormal wear before proceeding

Procedure

1. 1

   Compress brake caliper piston
   Using a C-clamp or brake caliper piston tool, slowly compress the caliper piston fully into its bore. Place the clamp against the back of the caliper body and against the outer brake pad backing plate. This creates clearance for caliper removal and pushes fluid back to the master cylinder. Monitor the brake fluid reservoir to ensure it does not overflow.
   ⚠Compress piston slowly to avoid damaging caliper seals or forcing contaminated fluid back into ABS system.
2. 2

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear side of the caliper (accessible from behind). Using a 17mm wrench or socket, remove both upper and lower slide pin bolts completely. Note their condition and thread engagement depth for reinstallation.

3. 3

   Remove and support brake caliper
   Carefully lift the brake caliper assembly off the caliper bracket and rotor. Do NOT disconnect the brake hose. Immediately secure the caliper using wire or a bungee cord to a suspension component above the working area. Ensure there is no tension or sharp bending on the brake hose. The caliper should be supported at approximately the same height as when installed.
   ⚠️Never let the caliper hang by the brake hose. Internal hose damage may not be visible but can cause brake failure.
4. 4

   Remove brake pads and hardware
   Remove both inner and outer brake pads from the caliper bracket. Remove all pad hardware clips, anti-rattle springs, and shims from the bracket. Keep these organized if reusing, though new hardware is recommended with bracket replacement. Inspect pad thickness and condition.
   ℹ️Mark pad orientation if reusing. However, installing new pads with a new bracket is recommended.
5. 5

   Remove caliper bracket bolts
   Using a 14mm socket and breaker bar if needed, remove the two caliper bracket mounting bolts. These bolts thread into the steering knuckle and are torqued very tight. Remove both bolts completely and set aside (these will not be reused if applying fresh threadlocker).
   ⚠These bolts are extremely tight. Ensure socket is fully seated to avoid rounding bolt heads. Use a breaker bar if necessary.

6. 6

   Remove caliper bracket from knuckle
   Once both bolts are removed, pull the caliper bracket assembly straight away from the steering knuckle. The bracket should slide off the knuckle mounting surface. Remove and discard the old bracket.
   ⚠Avoid damaging the rotor surface or ABS wheel speed sensor wire during bracket removal.
7. 7

   Clean mounting surfaces
   Using a wire brush and brake cleaner, thoroughly clean the caliper bracket mounting surface on the steering knuckle. Remove all rust, corrosion, old threadlocker, and debris. Clean the bolt holes in the knuckle. Ensure mounting surface is flat and smooth for proper bracket seating.
   ⚠Use brake cleaner in well-ventilated area. Avoid breathing vapors.
8. 8

   Prepare new caliper bracket
   Unpack new caliper bracket and verify it matches the old bracket design. Clean the mounting surface of the new bracket with brake cleaner. Apply a thin layer of copper anti-seize to the bracket's contact surface with the knuckle (optional but helps prevent corrosion). Install new brake pad hardware clips into the bracket according to their orientation.
   ℹ️Ensure hardware clips snap fully into place and are oriented correctly for pad fitment.
9. 9

   Install new caliper bracket
   Position the new caliper bracket onto the steering knuckle mounting surface, aligning the bolt holes. Apply medium-strength threadlocker (blue) to the threads of both new or cleaned caliper bracket bolts. Start both bolts by hand to ensure proper thread engagement. Using a torque wrench and 14mm socket, torque both bracket bolts to specification in a crisscross pattern.
   ⚠Threadlocker is critical for these bolts. Ensure threads are clean and dry before application.

    Install brake pads and hardware
    Install the inner and outer brake pads into the caliper bracket, ensuring they seat properly in the hardware clips. Pads should slide smoothly in the bracket with minimal play. Verify proper orientation with friction material facing the rotor. If reusing pads, install in same orientation as removed.
    ℹ️New pads are strongly recommended when replacing the caliper bracket to ensure optimal performance.
11. 11

    Clean and lubricate caliper slide pins
    Remove the slide pins from the caliper if not already removed. Wipe them clean of old grease and inspect rubber boots for tears or damage. Apply a thin coat of high-temperature silicone brake grease to the smooth portion of each slide pin (not the threads). Reinstall pins into caliper body, ensuring boots seat properly.
    ⚠Use only silicone brake grease. Petroleum-based grease will damage rubber boots and cause caliper seizure.

    Reinstall brake caliper
    Remove the wire or bungee cord supporting the caliper. Carefully position the caliper over the brake pads and bracket, aligning the slide pin bolt holes. Insert both upper and lower slide pin bolts and hand-tighten. Using a torque wrench and 17mm socket, torque both slide pin bolts to specification.
    ⚠Ensure brake hose is not twisted or kinked when positioning caliper.

    Reinstall wheel and torque lug nuts
    Clean the wheel hub face and wheel mounting surface. Install the wheel onto the hub, starting all lug nuts by hand. Lower vehicle partially so tire contacts ground but vehicle weight is still on jack stands. Using a torque wrench and 19mm socket, torque lug nuts to specification in a star pattern. Fully lower vehicle and remove jack stands.

    Restore brake pedal and check fluid
    Before moving vehicle, pump the brake pedal slowly several times until it becomes firm and reaches normal height. The pedal should feel solid after 3-5 pumps. Check brake fluid level in master cylinder reservoir and top off with DOT 3 brake fluid to MAX line if needed. Inspect for any fluid leaks around caliper and connections.
    ⚠️Vehicle CANNOT be moved safely until brake pedal is pumped up. Failure to do this will result in no braking on first pedal application.

Reassembly

1. If replacing both front caliper brackets, repeat entire procedure for opposite side
2. After completing work on both sides (if applicable), verify both wheels are properly torqued
3. Ensure all tools and parts are removed from under vehicle and wheel wells
4. Check brake fluid level one final time after both calipers are serviced

Verification

• With vehicle still parked, pump brake pedal multiple times. Pedal should be firm and reach normal height within 3-5 pumps
• Start engine and verify brake pedal does not sink with sustained pressure
• Inspect all work areas for brake fluid leaks while assistant applies pedal pressure
• Verify no tools or parts are left in wheel well or under vehicle
• In a safe area with no traffic, test brakes at low speed (5-10 mph) to verify proper function before normal driving
• During test drive, verify no pulling to one side, no unusual noises, and normal pedal feel
• Perform several moderate stops from 25-30 mph to bed in new brake components if pads were replaced
• Re-check lug nut torque after driving 50-100 miles
