I have a 2001 35' Condor by R-vision. I have had brake problems for sometime now. Just the front brakes stop the bus. I have replaced the brake shoes , all 4 wheel calipers with brand new calipers, the master cylinder. I presently have it at a workhorse dealership for going on 4 weeks now and the ABS checks out OK. I am lost , can somebody help ? Thanks (email@example.com) PS The dealership is lost also.
