i have a problem with my breaks honda cant seem to find a problem as they are only checking ecu and pads and discs, i can drive round town for as long as i want with no problem, but if i go on the motorway for around 40 minutes or more, when i break there is long travel on the pedal, the breaking distance doubles and have to pretty much do an emergency stop to slow down, there is also a chugga chugga sound like a train and a tapping feedback in the break pedal as if the abs was cutting in, i have spoken with other garages who think it may be a build up of pressure in the abs pump due the the heat and constant high speed, was wondering if anyone else has had this problem and if so how you fixed it.
