Hey guys. I have a question I hope one of you can answer for me. I was working on my brother's truck yesterday doing some maintenence. I also replaced the headlight switch since his fog lights weren't working and I also replaced the RWAL speed sensor on the rear differential. The truck is a 99 Ram 1500 auto with the 360. The brake light on the dash as well as the dash ABS light were on. The truck would have a tendency for the wheels to lock up even when applying normal brake pedal pressure. Speedometer worked fine. After changing the sensor on the differential the lights remained on. So I disconnected the negative battery cable for a few minutes. After reconnecting the cable and starting the truck the lights were out. We drove around the block and everything looked good. No warning lights and when I told him to stomp on the brakes they didn't lock up anymore. Well he just called me a few minutes ago and said while driving to work this morning (about 15 miles) both the brake light and the ABS light came back on again. I noticed yesterday when I put the emergency brake on that there was very little to no resistance in the pedal. Also the truck rolled backwards and it appeared the emergency brake was not holding the vehicle. What I'd like to know is this. Is the emergency brake adjustible? If so how do I adjust it? Would a bad or misadjusted emergency brake cause the ABS and brake warning lights on the dash to come on? Also he's never had new brake shoes put on the rear wheel of his truck. He's done the front pads but not the rear. Would this also cause the two warning lights to come on? Fluid level is fine. Or could it be a bad sensor? I don't think the sensor is bad but I guess a new one could be bad. My bet is on the back brakes needing to be serviced but I want to confirm this with you guys. Truck has just under 100K on it. I do have the factory service manual here on a CD from when I owned my 01 Ram. Thanks.
