how hard is it to change front air bags? think I have a leak in the bags they don't look good.I will use soap on them Monday.Are they also on the rear of the motor home?
THANKS
LENNY

Lenny, I have changed the rear bags and it took longer to let the jacks down and raise the coach than change the bags. Haven't changed front bags.

Nick

i THINK I WILL CHANGE THEM ALL.THANK YOU
LENNY

What makes you think the bags are defective? They are almost never the problem - usually the connections in the various line joints are the source of bleed down. I just had mine diagnosed and the shop detached each fitting and then moved the small sealing ring up about 1/4 inch, cuts off the end where the ring was seated and reattached the fitting. That involves about a dozen fittings but after five days of sitting the pressure dropped from 100 psi to 109 psi and I am now happy. That service is lots cheaper than replacing bags and still having leaks.

Based on your statements I would be inclined to have it properly diagnosed instead of just replacing all your airbags. Not only will your air system be deflated, but your wallet will too.

Wow... you gain air psi while sitting Tom?

I was guessing they were ok it was the air line dump valve switch inside on the floor was shorting out just got panicky that is all.
thanks lenny

Is this "air line dump valve" a dump of the airbags only? ...or does it purge air/water from the two brake systems?

Mike, I'm guessing but I have a coach similar to Lenny and I was assuming he was talking about the switch mounted on the HTH leveling system that dumps the airbags only when you level the coach.

That's what I was thinking when he talked about 'dump valve on the floor'. What was confusing to me is a different post where Lenny said the air gauge on the dash indicated front air pressure dropped as far as 25 lbs and was setting off alarms. I was trying to connect that symptom with air bag problems and obviously don't understand how his Regency air system is set up. I thought I understood Gillig's setup, but.....

it was both front air brakes and the air went to 25 lbs. and loose wire on the air dump sorry for the confusion too many problems at a time .does anybody have a pacbrake ? do I need it?got the parts Saturday and of coarse they end just where I need the questions answered .on the release valve where does it go (no place), just into the air or is there a tube that goes somewhere? am calling tech Monday. NOBODY KNOWS have the book but it stops were I need it .plus I will have to drill out the pipe plug on the pacbrake to check the back pressure .too much back pressure will hurt the engine I need 35 lbs ,I have the kit to check it .if anybody needs it I will lone it to them.It has a price tag of $90.00 no use of every body buying one.
