I own and automotive repair shop and do so work for our local RV dealer. We have a 1997 Pace Arrow with auto brake light that flickers when put into gear and then after about 90 seconds stays on solid and then will stay solid for 30 seconds and start flickering again. E-brake sets and releases. We noticed that the pump keeps running slowly when light is flickering and then stops running when light is solid. We have replaced solenoid and both pressure switches. We tested pump pressure and it was approximately 1700PSI. We suspected the other switch that is located at base of steering column. But it tested open in park and closed in any other gear. We think that is normal. Need any help you could give. |
