my Toyota Corolla E170 (2013-2019) brakes feel spongy what should I check

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
• Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

• Tools Required: Brake fluid, funnel
• Locate the brake fluid reservoir under the hood.
• Check the fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4).
• Ensure the cap is securely closed after topping off.

3. Bleed the Brake System

• Tools Required: Brake bleeder kit, wrench, clear tubing
• Begin at the wheel farthest from the master cylinder (usually the right rear).
• Attach the clear tubing to the bleeder valve on the brake caliper.
• Open the bleeder valve and have an assistant press the brake pedal slowly.
• Watch for air bubbles in the tubing; close the valve before the pedal is released.
• Repeat until no air bubbles are present, then move to the next wheel (left rear, right front, left front).

4. Inspect and Replace Brake Components (if necessary)

• Tools Required: Socket set, torque wrench
• Remove the wheel to access the brake assembly.
• Inspect brake pads for wear; replace if worn below manufacturer specifications.
• Check rotors for scoring or warping; replace if necessary.
• Reassemble the brake components and wheel, torque lug nuts to specification.
