BRAKE light on dashboard
I need help knowing what I need to fix since my BRAKE light on my dashboard is on after I fixed the brake hose on the drivers side and replaced both front and back brake pads.
Sorry Im late to the party @captainsnowball Its been a very busy week . Check the fluid level. Did you bleed the system after you replaced what Im assuming is the front flex hose . Have you just pumped the brake pedal a few times to get fluid pressure up . That will also often cause the light to go out . If the brake fluid is burnt and really dark looking it can also trip the sensor on the master cylinder . If this is the case then flushing the system is required . Just some ideas to kick around Hope this helps
@vladsc50 , The brake light in the instrument cluster will light up when the balance of pressure from the front brake system to the rear brake system. In the lines leading from the master cylinder, there is a pressure differential valve.
PRESSURE DIFFERENTIAL VALVE
The pressure differential switch is connected to the brake warning light. The switch is actuated by movement of the switch valve. The switch monitors fluid pressure in the separate front/rear brake hydraulic circuits. A decrease or loss of fluid pressure in either hydraulic circuit will cause the switch valve to shuttle to the low pressure side. The movement of the switch valve lights the brake warning lamp.
Once the pressure equals out the switch will return to normal. This will probably require bleeding the front and back brake hydraulic circuits. Be careful not to let the fluid in the master cylinder run out when bleeding, as that will introduce air into the system at the very beginning and will be very difficult to remove. When you are done bleeding the light should go out. If not, the pressure differential valve may need replacing. Hope this helps.
Check to make sure the parking brake is off.
