|Auto Park Brake Fix||manati||10-18-10|
|DON’T COMPROMISE YOUR SAFETY! Quick fixes could cost you your life, the life of your love ones and everyone else around you!|
Don’t put yourself or your family on harms way, by taking the advice of people that are not trained with the auto park brake system.
The auto park brake system has a tension spring that is crucial in the proper function of the system, if the spring does not have the correct tension it will not hold the pressure and you could find yourself with a runaway vehicle. There’s more to rebuilding the auto park brake actuator than just replacing seals as some people like you to believe, otherwise the manufacture would have a repair kit and/or there would also be a lot more mechanics shop rebuilding the system.
The hydraulic system activates the spring, and the spring is what locks the brakes. If both are not up to par you will find yourself with no parking brake nor emergency brake.
The spring holds the brakes not the hydraulic system, overtime the spring may loose its tension and collapse, during the rebuilding process the springs has to be removed and carefully inspected and tested for proper tension.
The spring is compressed in the cylinder for years, this may collapse the spring overtime, and if not checked by a trained technician; how do you know that your spring has the proper tension? For this reason the manufacturer does not sell repair kits they sell only the complete unit. By the time your seals go bad the spring may also need to be addressed.
When it comes to your auto park brake actuator you only have 2 safe choices,
1. YOU REPLACE THE UNIT WITH A BRAND NEW ONE or
2. YOU GET IT REBUILT BY A TRAINED TECHNICIAN.
THIS IS DEFENETELY NOT A DO IT YOURSELF JOB!

|Has anyone been able to get this problem fixed? We have a 1994 Flair on a P30 Chassis. It's been repaired twice, M/H will not move. Lost the brakes and steering on the Delaware Memorial Bridge, managed to get it home, it has now become a "Pool House". That's not what we bought it for. I don't think it can even be towed, all the wheels are locked up. What can be done ?|

|Re: Auto Park Brake Fix||james juarez||12-9-10|
|Ok people. the auto park brake on the various p30 chassis over the years. has change how it works, or how it's actuated. the early models while scary looking, is not. these models as you all know use the hydroboost system to build the pressure necessary to release the parking brake automatically.yes it can be released manually, it requires you to get under your motorhome. and backing off the adjusting barrel looking nut, as it staqrts to loosen you should be able to hear it relaxing. please think before you do this. because once loose the vehicle can roll on it's own and squish you dead!!! so block the wheels prior to trying this. anyway the power steering pump needs to build upwards to 1600 psi to release the brake and operate the coach brakes and power steering simultaniously. did i spell that right? if your pump reservoir is really low on fluid or you have a leak in the system somewhere. air will enter and cause both the brakes and power steering to cease functioning. if you have a leak, the parking brake light will come on and never go off. this happens to alert you of a leak in the system. and lets face it if you fluid is low, you have a leak. so lok for it. i figured out that i could take the overflow hose from my reservoir and insert nit in a gallon jug of new ps fluid, about a quarter of the way. and instead of sucking air when you move your trans from park to drive. it sucks ps fluid which will keep your parking brake from locking up until you can get to a shop or a safe place whichever works for you. before i put the tube in the jug ps fluid was spraying all over my motor and frame left front brake, not to mention the roadway. all of these coditions are dangerous for yourself, and other motorists. now here's something else. if your emergency brake pedal does not seem to do anything. you can adjust the brake shoes on the brake behind the trans. merely line up the slot provided by GM, right about eleven oclock as you look up at the unit. take your brake spoon and adjust the adjuster by moving the adjuster in a clockwise direction. or if you prefer from bottom to top. this can sometimes correct the problems you might be having. but i would not hold your breath. happy motoring, email@example.com|

|Re: Auto Park Brake Fix||Allen Douglas||10-18-10|
You are correct; I had problems with the actuator on my '99 Fleetwood Flair. I called around no one had a clue on how to repair the actuator. I had to tow the RV to a local service center and again no luck. I was referred to Mr. Crespo by a local service center that sends actuators to him for repairs.
Mr. Crespo rebuilt it for me over two years ago. To this date the actuator works great!
I highly recommend Mr. Crespo for his knowledge, professionalism and prompt turnaround his contact is: Jose Crepo, Ph: 305-218-8875, Email: firstname.lastname@example.org

|Mr. Thomas Lobdell, |
I highly recommend Mr. Jose Crespo, he is very knowledgeable about the system. He rebuilt my actuator and located for me the Hydraulic Relay Valve (obsolete part 106950), I have the older system 92 coach, my mechanic looked around for almost a year and Mr. Crespo quoted me within 5 minutes.
Here is Mr. Crespo's information:
|Re: Auto Park Brake Fix||Lee Wilson||2-3-11|
|The auto parking brake is Dangerous!!! It depends on the power steering pump to build enough pressure to activate the bendix actuator to release the parking brake. When the pump loses pressure from leaking hoses or breaks in the hydraulic system or from a failure in the power steering pump, The automatic parking brake will either pulse or lock down!!! you may be in heavy traffic or on a downhill roll either way you are in trouble!!! the brake will lock down and generate enough heat until seals will melt causing a fluid leak and the fluid will ignite into a huge fire. I have seen this happen. I would remove this automatic parking brake.|

|Hi and I hope you can help me.My chevey has the yellow swich in the dash and park position on the gear lever. My partking brake does not work at all. I can see fluid from inside the RGS which is probly faulty. How do I determine if it is faulty or the actuator switch is faulty? Does the RGS sense the pressure and sense when to turn the motor on and off? Also the light works correctly on the dash. i.e when the pull out the yellow knob or move the lever out of park,the light works correctly,altho if I move off it will flicker. Is this a case of the RGS being faulty? I HOPE YOU CAN HELP ME.|
|Re: Auto Park Brake Fix||Charlie||3-2-11|
|Right on Ron. I am fixing mine now witht he same issue. It was a green switch Part #15961566 for $54 at AO'Reilly that fixed my leak problem.|
|Re: Auto Park Brake Fix||Ron||2-9-11|
|Ok people I agree that you need to get it fixed but not all P30 brake issues requires a rebuild by a pro. First you need to diagnose the real problem instead of shelling out big bucks do some testing. Is it the RGS rotten green switch, a bad sensor or does it really need to be replaced. I had a pro tell me oh yeah needs to be replaced and would only cost $3500.00. Yea right. I searched the Internet found Rv.net and a man named oldusedbear aka Roger Haag he had me under the rig and diagnosed the problem in 15 mins. It was the switch. I got a new one on amazon.com for $36.00. And the rig is great now|

|1996 Winnebago Adventurer, 454, 7.4, Gas engine.|
Driving home from vacation back in August of this year, and my Park Brake light came on and would not go off. I had a few miles to drive to get home so I kept driving. My wife smelt a burning smell, almost like rotten eggs, as we were driving, and as a result we now do not have Auto Park Brake or P(park) when I shift the gear shift into Park. The vehicle just rolls when I shift into park. Also I have had a track record of difficult shifting from Park into R, D, etc. Please advise what went wrong, and big of a job is this to repair. Also, is it a repair job for a transmission shop, or someone such as Camping World,etc. Please advise. Thank you.
