Common symptoms can include abnormal noises when braking, a spongy brake pedal, or warning lights on the dashboard. It is essential to address any brake concerns promptly, as they can affect vehicle safety.

Brake fluid tester
Torque wrench
Jack and jack stands
Lug wrench
C-clamp or brake caliper tool

Screwdriver set
Safety glasses and gloves

Repair Instructions

If Brake Pads are Worn

Lift the Vehicle:
- Use a jack to lift the vehicle and secure it on jack stands.
Remove the Wheel:
- Use a lug wrench to remove the lug nuts and take off the wheel.
Remove the Brake Caliper:
- Use the appropriate socket to remove the caliper bolts.
- Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it from the suspension to avoid stress on the brake line.
Replace Brake Pads:
- Remove the old brake pads. Note their orientation for the new pads.
- Use a C-clamp to compress the caliper piston back into the caliper housing.
- Install new brake pads in the same orientation as the old ones.
Reassemble:
- Reattach the brake caliper and torque the bolts to the manufacturer’s specifications.
- Reinstall the wheel and torque the lug nuts.
Test the Brakes:
- Pump the brake pedal to ensure proper pressure before driving.

If Brake Fluid is Contaminated or Low

Flush the Brake Fluid:
- Use a brake bleeder kit to replace old brake fluid with new fluid.
- Start at the wheel furthest from the master cylinder and work your way forward.
Bleed the Brakes:
- Have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper.
- Continue until clean fluid flows from the bleeder.

If Brake Warning Light is On

Check Brake Fluid Level:
- If low, refill and check for leaks.
Scan for Trouble Codes:
- Use an OBD-II scanner to check for any error codes related to the braking system. Address any codes by diagnosing the relevant components.

Conclusion

While brake issues in the 2020 Toyota Highlander are not highly reported, it is crucial to remain vigilant and address any symptoms promptly. Regular maintenance and inspections can help ensure the braking system remains in good working order. If problems persist after following these steps, it may be advisable to consult with a professional technician for further diagnosis.
