I'm having a problem with my rear brakes. They lock up when I'm driving and smoke starts to billow out. Sometimes if I sit and wait for them to cool down for a while, I can drive it again but sometimes not. Highway driving seems to make the problem occur more frequently. Is replacing the RABS sensor the answer? I just had new rear brakes put on thinking that was the problem.
RepairPal Certified shops can diagnose and repair your 1993 Ford E-250 Econoline. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
You are not experiencing a RABS problem. Sounds more like a base brake system hydraulic issue. Start by having all the base functions checked and verified.
