Rob Posted November 17, 2008 Share Posted November 17, 2008 What is the valve called that has the yellow knob one pushes to release the spring brakes, (PP1, PP2)? The one in the "new" RL leaks when it is pushed in. A slight touch on the yellow knob from the side causes it to leak air also when the brakes are set.I'm to the point of doing maintenance on the air system and there are many leaks due to sitting I'm sure.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Rob Posted November 18, 2008 Author Share Posted November 18, 2008 Does it come apart easily?? Bet it's only a dry o-ring.How's the road trip plan coming along?Boss is kicking my ass out next week. Too much vacation time stored up he says. I'm planning on trying to get out of here on Tuesday morning at 7:00a.m. headed your way. I've got a new phone as I destroyed the other one, (again). I no longer have your phone number.Never taken apart an air valve before but do see where there are rebuild kits available. It is a PP1 series valve according to Bendix literature. I'll prolly look into getting this problem taken care of rather shortly. Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

I call it "the brake button". Quote Producer of poorly photo-chopped pictures since 1999.

Mike Posted November 23, 2008 Share Posted November 23, 2008 Rob,You might lubricate it with a little vasoline. It works wonders on all kinds of rubbery things. Just don't use too much, that stuff is difficult to get off easily.mike Quote Link to comment https://www.bigmacktrucks.com/topic/5109-leaking-air-valve/#findComment-24934 Share on other sites More sharing options...
