I have a 2010 Dodge Caravan. I had the master cylinder replaced because it was leaking, but now the brake light continues to come on after about 15 seconds after starting the vehicle. I have checked the reservoir and it is full. Also the pedal seems to be fine and I don't have any issues with stopping. However, I cannot figure out why the brake light continues to come on. Please let me know if you have any suggestions on what I can do. Thank you.

 

My suggestion would be to take it back to whoever replaced the MC and have them check it out.

 

Hi Sww,

Sorry to hear about this! If you decide to visit your local dealership for further diagnosis I'd be happy to offer assistance if needed. Just PM our page with your VIN and let me know.

I have already taken it back to the mechanic who did the work 3 times and he couldn't find why the light is still on. He is a family friend and can't find anything. It is bugging him just as much as it is bugging me. I also took it to a dealer and they just bled the lines and charged me $160. Never fixed the light.

I was curious if it was possibly the sensor gone bad, the sensor was stuck in the reservoir, or an issue with the dash light?

I have also read that some people changed their worn brake pads and it went away, but I was doubting that would be a solution. I do plan on putting new pads on this weekend so I will see if that works.

Thanks for any help or suggestions.

 

I have read of a few cases of the sensor going bad.

The sensor part number is 5175094AA.

 

I was thinking the same thing - faulty sensor.
