1998 chey venture. I have a problem with front drivers brake locking up and maintaining constant pressure. Seem to relieve some once engine compatment is warmed up and somehow builds pressure on the caliper after cooling down over night. I have replaced caliper and brake hose. Traction control light comes on and off periodically. And brake light is on constantly. Would this be a brake sensor, abs control unit or traction control computer?

. Lubricate the caliper pins with silicone grease or Squeak Relief.

. Bleed the complete brake system. This should be done every two years.
