Prevost – Ft. Worth
I am currently at Prevost – Ft. Worth. My bus has been here for almost two weeks now.
After starting the engine and releasing the parking brake, in a matter of maybe 60 second the Front, Rear and Aux systems will drop from 117psi to 96psi with my foot on the Service brake. I take my foot off the brake, still in neutral, the engine running, and in two more minutes all three systems drop to 77psi – 72psi and the parking brake light comes on.
Still in neutral, no brakes applied, no service brakes no parking brake, I run the engine rpms up and no air pressure will build up. Only when I engage the parking brake will air pressure build up and it builds up in about 1 min 20 sec.
Here is what Prevost – Ft. Worth told me would solve my problem and if I approved or disapproved the repair –
• Driver side wheel seal leaking – APPROVED
• Replace tag shocks – APPROVED
• Generator service – APPROVED
• Level 3 Service – APPROVED
• 2 red rear marker lights out – APPROVED, HOWEVER THEY DID NOTHING, telling me they could not match my marker lights with LEDs. My marker lights are ALL LED.
• Air system service – APPROVED
• Replace engine air compressor – APPROVED
• Fuel leak near Webasto preheater – APPROVED, however, I told them to just cap off the leak
• Replace upper control arms</strike> – NOT APPROVED
• Replace lower control arms</strike> – NOT APPROVEDI drove up to Prevost – Ft. Worth Tuesday, July 8th and spent the night so I could be ready for my 6am APPOINTMENT. After spending Tuesday night at Prevost Ft Worth and getting up at 5:30am for my 6am APPOINTMENT, it was 6 HOURS, close to NOON, before anyone came out to the bus to help me.
• 6:00AM – I spoke to the Lot Walker and he said, we’ll send someone right out to you.
• 8:10AM – I called my Service Writer and he said, we’ll send someone right out to you.
• 9:15AM – I called and my Service Writer was in a “Meeting”. The Front Desk said they will ask the Lead. He told the Front Desk to tell me, we’ll send someone right out to you.
10:15AM – I called my Service Writer and he said, we’ll send someone right out to you.
• 11:55 AM – A Tech finally wondered to my coach and took my bus in for inspection after I described the parking brake / loosing air pressure problem.
• 1:30PM – I was told I needed a new D/S drive axle inner wheel seal, the brakes had over heated, and the engine compressor had failed, etc.
• 2:00PM – I was told it would be Friday before all repairs would be complete and I could not stay in the bus
• 2:30PM – I was told in would be Monday, July 14th before all repairs would be complete and I could not stay in the bus. I had my son in Dallas drive me three hours home.
• Monday, July 14th – I was told it would be Tuesday or possibly Wednesday, July 16th before all repairs would be complete. I told Prevost I would drive up and sleep in the coach Wednesday night.
• Wednesday, July 16th – I arrived at Prevost at 7pm and they were still working on the bus
They continued working on my bus until Friday, July 18th, finishing at 3pm as they were closing.
I try to leave the next morning, Saturday, I press on the Service brakes to stop twice, once at the Exit Gate and once in front of their office and brake pressures drop from 115psi to 77psi & 72psi. Parking Brake light come on.
I am still at Prevost – Ft. Worth for the same problem I brought the bus in for repair to begin with.
I have driven this bus 272,000 miles and been a Prevost – Ft. Worth customer for around 25 years. My brake air pressure would only drop a few psi when the service brakes were applied. A drop of 20psi is unacceptable and dangerous.
Prevost – Ft. Worth drove my bus 11 miles and had the engine running for over 6 hours while my bus was in their possession. How could they miss this drop in air pressure ? They told me my problem had been repaired and were letting me drive the bus home in this dangerous condition.
While everyone has been very polite and professional to me, the lack of progress, the time to solve and repair my service request is appalling. It used to be much better here.
The Air Service is supposed to check for air leaks, check service brakes system, check park brake system among other items. Did they actually check the brakes since that is why I brought my bus in to begin with. I caught the problem after just stopping twice trying to leave the parking lot yesterday.
I am still here for the same problem that brought me here to begin with.
• What is going on with my parking brake and what is allowing me to lose all that air pressure so quickly ?

I had Prevost replace my engine air compressor despite one shop saying it was critical and one asking why I wanted to do that. After the replacement there was a serious air leak at the new compressor and I had to take it to another Prevost shop to have that corrected. Just suggesting that the new air compressor might be the source of the problem.
Good luck! Mine is a 40′ 98 CC as well. Not the original owner! I’m impressed that you are.

sorry for your problem. i may have had a similar problem with our 2000 country coach. on our way south to florida on interstate 95 a couple of years ago i noticed a loss in air pressure when i used my brakes in traffic. the pressure built up quickly at first when i let off the brakes, but as we got further the drop in pressure got worse. i pulled over to inspect and could hear an air leak in the engine compartment but could not locate the leak. i limped the bus to florida and set up an appointment with a shop. when the tech came out i showed him what i knew and he listened a bit and went and got an air leak headset and found that the main airline coming from the compressor to the main air tank was leaking. they called prevost and were told that the line was about $1,000.00 but was on backorder and was not expected for 10 months! we were not going to sit in the parking lot for 10 months (we live full time in the bus). after some help from the shop, we found a hose shop in daytona (1 hour away) that said if we brought a piece of hose and the 2 ends they could make me a new hose. we took the ends and hose piece in our pick-up to the shop and while we waited (45 minutes) they found the correct new ends and suitable hose to make the 10’ +/- high pressure, high temperature stainless covered replacement. price for the hose was around $400.00. after we got back to the shop they installed the new hose and we were fixed. if i remember correctly, their bill was for only 2 hours and we we on our way. no more leaks. good luck!
