I have a 1988 Toyota Camry 2.0L 195,000 miles Automatic. I replaced the front brake pads and got some air in the line and started having brake sticking problems a few months later. The brakes have more recently started sticking on to the point of not releasing after about 15 minutes of driving. I crack open the bleeder valve and release the pressure and it is fine for a few more minutes. If let to sit several hours it is good again for another 15 minutes. I have replaced the driver side caliper (the side that is sticking) I have bleed the brakes. I replaced rotors and pads on both sides and bleed brakes again. Still having the problem. I have bought the brake hose to replace that but am getting frustrated with fixing things that aren't the problem. Could it possible be the hose or would it be a waste of time? And special tools need to replace that hose? Frustrated and wanting to make it to 200,000.
