Not much of a mechanic but better to know whats causing problem before taking truck to mechanic.
Have 2004 150 4x4 with 175K mileage. Have been experiencing an intermittent problem with driver side front break. In cool rainy weather, no problem. In hot humid conditions, typical for NJ, after about 45 minutes braking becomes difficult and truck lurches under braking. Steering wheel vibrates heavily. Problem repeats under hot conditions. Caliber sticking (?) and is it easily repairable or need replacement? Secondary to that issue, if driver side caliper replaced, should pass side be replaced as well?
Thanks in advance for any help/direction forum can provide.
