Brake Fluid Level Warning Indicator Switch Replacement Cost Estimate

Any skilled technician will have a diagnosis pointing to the brake fluid level warning indicator switch within a few minutes. Testing of the circuit is quick and easy, and typically will not require removing any obstructions before testing. The fluid level will be checked, and the pigtail (wiring) for the switch will be checked for continuity. If the wiring harness functions properly, but the switch is ineffective, it will be replaced.

Removal of the switch may involve removing the brake fluid reservoir cap, unscrewing the brake fluid level sensor from the reservoir, or simply removing a clip. One electrical connector will be disconnected, and the seal will be replaced when re-installing the switch. Depending on the location of the brake fluid level warning indicator switch, the technician may feel there is a risk for letting air into the system, and may need or advise to perform a brake fluid flush and bleed.

Since there are occasions when the brake fluid level warning indicator switch fails, it is recommended to regularly check your fluid levels. Again, if the brake fluid level becomes low without warning, the brakes will lose effectiveness.

When performing any service on the brake system, it may be advised to flush the brakes, however, brake fluid flushes are one of the most commonly recommended services as an attempt to raise a repair bill. Knowing when your vehicle's brake system should be flushed is necessary to avoid needless upcharges. Your owners manual will advise when one should be conducted, and any time there is air in the system the brakes should be flushed and bled as well.

Replacing this switch should be a mior task if the switch is located on the top of the reservoir, or even high on the side of the brake fluid reservoir. The point that a DIY mechanic should refer the vehicle to a technician is if the sensor is so low in the reservoir that there is a risk of letting air into the brake system during the repair, unless the person servicing the vehicle is familiar with flushing and bleeding brakes. If bleeding the brakes is too far removed from personal experience, seek professional assistance.
