AllanD Posted April 13 Report Share Posted April 13 So might be a long story here but will try to make it brief. Two weeks ago, when I pushed on the brake pedal I would here massive air coming out of that area. I took it to the garage up the road (that I have used many times before) and was told that it was the brake booster. Made sense to me for the age and mileage and the sound I was hearing, so I had that replaced. Brakes where fine a few days after that I noticed that my anti-traction light was coming on and the rear brakes lights were staying lit until I tapped the brake pedal. I did some googling and found others saying it sounded light the brake switch near the pedal. I was able to replace that myself and everything was good for a while. I noticed that the brakes started either going to the soft like all the way to floor and then next it would be rock hard. I took it to the same garage and was told it was now the master cylinder and that the piece I replaced was good since it was just showing old codes. I picked it up on Thursday and now the ant-traction light came on today, rear brake lights remained on until I pushed on the pedal, the breaks are getting spongy again, and when depressed all the way when stopping they feel grindy. I hope this all makes sense, just scratching my head not sure what it can be. Quote Link to comment Share on other sites More sharing options...
AllanD Posted April 29 Author Report Share Posted April 29 Sorry for double posting but have been doing a little research and all leads to brake light switch. I put another Motorcraft switch in and now the anti-traction light still comes on and the rear brake lights stay on until I tap the brake pedal. Completely lost here.

garycrist Posted April 30 Report Share Posted April 30 (edited) As a shot in the dark, have you tried to cycle the ABS valves? Or, try going down a gravel road and do some lock-ups to exercise the ABS valves. I could be wrong but, I've seen lots of recomendations along that line. Also addressed here already too. Let us know... Edited April 30 by garycrist Quote Link to comment Share on other sites More sharing options...
