Brake Pads - Rear

Replace worn rear brake pads on a 2014-2019 Toyota Corolla 1.8L to restore braking performance and safety.

Warnings

Tools required

Parts

• Rear brake pad set × 1 — Use OEM specification (04466-02280 or equivalent)
• Brake pad shims and hardware kit × 1 — Typically included with pad set
• Anti-squeal compound (if not pre-applied) × 1 — Use OEM specification

Fluids

• DOT 3 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid ground and engage parking brake
2. Loosen rear wheel lug nuts 1/4 turn while vehicle is still on ground
3. Lift rear of vehicle with floor jack and secure on jack stands at proper jacking points
4. Remove rear wheels completely
5. Remove approximately 1/3 of brake fluid from master cylinder reservoir using turkey baster to prevent overflow when compressing pistons

Procedure

1. 1

   Remove caliper slide pin bolt
   Locate the lower caliper slide pin bolt (14mm) on the rear of the caliper. Remove only the LOWER slide pin bolt while supporting the caliper body. The upper bolt will serve as a hinge point to swing the caliper up and away from the pads.
2. 2

   Pivot caliper upward
   Carefully rotate the caliper upward, pivoting on the upper slide pin. Support the caliper with a wire hanger or bungee cord attached to the suspension to prevent stress on the brake hose. Do not let the caliper hang by the brake line.
   ⚠Never allow the caliper to hang unsupported by the brake hose, as this can damage the hose internally and cause brake failure.
3. 3

   Remove old brake pads and hardware
   Remove the inner and outer brake pads from the caliper bracket. Remove the pad shims and anti-rattle clips. Note the orientation and position of all hardware for reinstallation. Inspect the brake rotor surface for deep scoring or damage.
4. 4

   Clean caliper bracket and slides
   Use a wire brush to clean the pad contact areas on the caliper bracket. Remove all rust, debris, and old grease from the slide pin bores and bracket surfaces. Spray with brake cleaner and wipe dry. Inspect slide pins for corrosion or damage.
5. 5

   Compress caliper piston
   Using a C-clamp or brake piston tool, slowly compress the caliper piston fully into its bore. Place the clamp against the back of the caliper body and a clean piece of wood or old brake pad against the piston face. Compress slowly and watch the master cylinder reservoir for overflow.
   ⚠Monitor the brake fluid reservoir during compression. If fluid overflows, it will damage painted surfaces. Remove additional fluid if necessary.
6. 6

   Lubricate slide pins
   Remove the upper slide pin and inspect both pins. Clean thoroughly and apply a thin coat of high-temperature silicone brake grease to the smooth shaft portion of both slide pins. Do not use petroleum-based grease. Reinstall the upper slide pin into the bracket.
   ⚠Only use silicone-based brake grease on slide pins. Petroleum-based products will degrade rubber components and cause brake failure.
7. 7

   Install new pad hardware and shims
   Install new anti-rattle clips and pad support hardware onto the caliper bracket according to the positions noted during removal. Attach new shims to the new brake pads, ensuring anti-squeal compound is applied between shim and pad backing plate if not pre-applied.
8. 8

   Install new brake pads
   Position the new inner and outer brake pads into the caliper bracket. Ensure pads are properly seated in the bracket hardware and can move freely. Verify the wear indicators are positioned correctly (typically on the inner pad, facing the leading edge of rotor rotation).
9. 9

   Reinstall caliper
   Swing the caliper down over the new brake pads. Ensure the caliper piston dust boot is not twisted or damaged. Align the lower slide pin hole. Apply medium-strength thread locker to the lower slide pin bolt threads.
10. 10

    Torque caliper slide pin bolt
    Install the lower caliper slide pin bolt and torque to specification using a torque wrench. Verify the caliper can move freely on the slide pins by pushing it side to side with moderate hand pressure.
    ⚠️Proper torque on slide pin bolts is critical for even braking force distribution. Under-torquing can cause bolt loosening; over-torquing can seize the slides and cause uneven pad wear or brake failure.

    Repeat for opposite side
    Perform steps 1 through 10 on the opposite rear brake assembly. Always replace brake pads in axle sets (both rear wheels) to maintain balanced braking.
12. 12

    Reinstall wheels
    Clean the wheel hub face and mounting surface. Reinstall the rear wheels, threading lug nuts by hand first to ensure proper seating. Snug lug nuts in a star pattern but do not fully torque yet.
13. 13

    Lower vehicle and torque lug nuts
    Lower the vehicle from jack stands to the ground. Torque wheel lug nuts to specification in a star pattern using a torque wrench. Recheck each lug nut in sequence to ensure proper torque.
    ⚠️Improperly torqued lug nuts can cause wheel separation while driving. Always use a torque wrench and follow star pattern sequence.

    Restore brake pedal pressure
    Sit in the driver's seat and pump the brake pedal slowly and firmly 10-15 times until pedal feels firm and consistent. Check the brake fluid reservoir and top off to the MAX line with DOT 3 brake fluid if needed. Do not overfill.
    ⚠️The brake pedal will go to the floor until pistons are repositioned against the new pads. Never attempt to move the vehicle before pumping the pedal and verifying firm pedal feel.

Reassembly

1. Verify brake fluid level is between MIN and MAX lines in the master cylinder reservoir
2. Ensure all tools and parts are removed from wheel wells and under vehicle
3. Check that all wheel lug nuts are properly torqued in star pattern

Verification

• Pump brake pedal 10-15 times and verify firm, consistent pedal feel with no sponginess
• With engine running, verify parking brake holds vehicle on an incline
• Test brakes at low speed (under 5 mph) in a safe area to verify proper operation before normal driving
• After 50-100 miles, re-torque wheel lug nuts to specification
• Brake pads require 200-300 miles of bedding-in for optimal performance; avoid hard braking during this period
• Inspect for any fluid leaks around caliper and brake lines after test drive
