The Brake assist and traction control light is on, and brake is to the floor and does not work well. What could be the problem?
Sounds like you have a brake fluid leak. Remove the top of the master cylinder and check the fluid level. Both chambers should be 1/4" from the top of the resivoure. If one chamber is low or empty there's the problem. Get it fixed ASAP!! Faulty brakes are nothing to fool with!! HTH. -Jim
