This push switch is a critical component in the brake system, activating warning lights or interlocks when a specific brake condition is met. It is manufactured to meet stringent quality standards, ensuring reliable operation unlike a worn switch that may stick or fail to engage. Operators may notice the brake warning light illuminating erratically, failing to illuminate when needed, or the equipment preventing operation due to a faulty brake interlock.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An illuminated brake warning light that does not extinguish when the brake pedal is released is an early sign of a faulty switch. If ignored, the warning light may become intermittent or fail to activate altogether, potentially masking other brake issues. This could lead to an operator being unaware of a critical brake system malfunction.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before plugging it into the new switch. Avoid overtightening the switch during installation, as this can damage the threads or the switch housing.

Service Note

Inspect brake fluid levels and check for any leaks in the brake lines when replacing this switch.
