Brake pressure builds up after starting approximately 1 min. After applying brake couple times, warning light comes on and brakes go away.New brake cylinder was installed after found leaking. Problem still exist. Any suggestions
In order of what to check: - 1. Accumulator precharge pressure on both accumulators (T&A Page 12). 2. Accumulator charging valve for correct function (T&A Page 8). 3. Brake pump. Attached the SysOp so you can understand how the brake system operates works and the T&A so that you can test the above.
