Has anyone one out there had luck finding calipers, rotors, pads for the 2001 HR Ambassador. If I'm understanding right, I've got the phenolic piston in my calipers. If the RV sits for 3 to 4 weeks the calipers sticks. I can drive it down the road 4 or 5 miles and put heat in the brakes, let it sit over night and it does fine on the trip. I've changed the brake fluid and that really helped. It's on a Roadmaster chassis model 26000. I'm really hoping to find someone who has changed there's and has parts numbers....thanks again guys.. 2001 H/R Ambassador Monaco coach #120383 36pbd ISB 300 eng. VIN # 1RF12041912012180 (8/2000)
