My high pressure sensor keeps turning on (already replaced brake master cylinder a couple months ago with a used one off ebay) after replacing front brake lines with StopTech fronts, every so often the sensor comes on for 10-15 seconds then turns off. Any thoughts?

 

"high pressure sensor" I don't think I have ever had an issue with that sensor? Can you tell me more about the issue?

 

usually means you need to change the brake master cylinder it has a high pitch sound constantly with traction control abs and ebrake light on, comes on and off sometimes probably due to my front brake lines

 

front brake lines are metal now btw
