Toyota Corolla 1.6 (2002): Brake System Bleeding with Fluid Replacement

Bleeding is done after replacing the fluid, repairing brake lines, calipers or cylinders, or when the pedal feels soft. The fluid should be replaced about every 2 years. The Corolla E120 has a dual-circuit brake system, so it is important to follow the correct order and never let the reservoir run empty. On ABS versions, a standard two-person bleed is usually enough as long as no air has entered the ABS unit.

Difficulty: Medium Time: 1-1.5 hours Steps: 12 Tools: Helper (or clear hose and a jar), 8 mm or 10 mm wrench for bleeder screws (box-end or bleeder wrench), lug wrench, jack and jack stands, syringe or turkey baster for removing old fluid, shop rags

Part

  • 🔩 DOT 4 brake fluid, about 1 L (1.1 qt) with some extra (any quality brand with a DOT 4 rating will do). Clear hose sized to fit the bleeder screw

Step by step

12 steps
  1. Park the car on level ground, apply the parking brake, and chock the wheels that stay on the ground. Turn off the engine and press the brake pedal several times with the ignition off to release the vacuum in the brake booster.
  2. Open the hood and clean any dirt off the reservoir cap. Use a syringe to remove the old fluid from the reservoir (if you are replacing all of it), then fill with fresh DOT 4 up to the MAX mark. Do not mix DOT 4 with silicone-based DOT 5.
  3. Jack up the car and remove the wheels one at a time. Start with the wheel farthest from the master cylinder: right rear, then left rear, then right front, then left front. This is the typical order for this model.
  4. Remove the protective cap from the bleeder screw and attach the hose. Put the other end into a clear jar containing a small amount of fluid so the end of the hose stays below the fluid level.
  5. Your helper presses the pedal smoothly several times and holds it down. Do not let the pedal up until the bleeder screw is closed.
  6. Open the bleeder screw about half a turn and let the fluid and air escape. Close the screw, and only then have your helper release the pedal.
  7. Repeat the cycle until clean fluid with no bubbles comes out of the hose. Every 2-3 cycles, check the reservoir level and top it up so it never drops below MIN. Otherwise air will get into the system and you will have to start over.
  8. Tighten the bleeder screw snugly with the wrench, without excessive force (the thread is fine and strips easily). Check the manufacturer's service manual for the exact torque. It is usually a small value, around 8-12 N·m (6-9 lb-ft) for caliper bleeder screws. Put the cap back on and wipe away any spilled fluid.
  9. Move on to the next wheel. If you are replacing all the fluid, keep bleeding each wheel until fresh, clear fluid comes out.
  10. Install the wheels and tighten the lug nuts in a crisscross pattern, with the final tightening done with the car on the ground. The lug nut torque for this generation is about 100-110 N·m (74-81 lb-ft). Check the service manual for your wheel type.
  11. Set the reservoir level to MAX and close the cap. Start the engine and press the pedal. It should feel firm and should not sink or drop when held for 20-30 seconds.
  12. Check the bleeder screws, hoses and calipers for leaks. Take a test drive at low speed in an empty lot and check the braking in safe conditions before driving on the road.

Common mistakes and warnings

  • The brake system is critical for safety. If the pedal is still soft after two full bleeding cycles, if there are leaks, or if a bleeder screw is seized or broken off, do not drive the car. Take it to a repair shop. Brake fluid damages paint and absorbs moisture from the air, so rinse off any splashes with water right away and do not leave an open container sitting out. Take the old fluid to a recycling facility.
