DD-3 to Spring Brakes Installation Guidelines and Tips

Silver Eagle Model 01

November 11, 2008

This is for installing the Spring Brake Chambers and QR-1C Valve only at this time. Since it is a single brake system, you will want to update and change it to a dual system. This will be explained in another document.

The following links and documents are ones I strongly suggest you read and study very thoroughly.

This Bendix site has a lot of good information you need to know about brakes, chambers, valves and air dryers etc. Spend lots of time on Spring Brakes and QR-1C valve. Get familiar with it.

https://www.bendix.com/EN-US/SERVICE/LI ... heets.aspx

Great reading here.

Parts Needed

• 2 ea. 30/30 Spring Brake Chambers
• 1 ea. QR-1C Valve, this is a two-way check valve, for anti-compounding of brakes when both service and park brake are engaged at the same time and to pressurize the emergency side of your spring brakes.
• Tube or jar of joint compound, do not use Teflon tape.
• Approx. one foot of 5/8 OS dia. DOT Nylon tubing. Get more, you never know when you might need some. I had some left over from the installation of my AD-9 air dryer.
• 2 ea. Push Lok or Compression fittings for the above tubing. One with 3/8” MP, this goes onto the delivery port of your rear relay valve. One with ¼” MP, this goes onto the Balance Port on your QR-1C.

If you are going to reuse your existing hoses and fittings off of your DD-3’s, make sure they are in good shape.
You may need other assorted brass DOT fittings depending on your installation.




Safety First

Park your coach on a level surface.
Block all wheels so coach does not roll in either direction.


Step One

Using coach or shop air, bring your air pressure up until governor sneezes or at least 100 psi, release the Park Brake. Shut off your engine, turn off battery switch and take your keys with you.
Go under the drive axle and look at and take pictures of how the DD-3’s are mounted. Also check and measure the position of the slack adjuster arm to the brake chamber bracket, this is of course if your slacks are set correctly. Measure from center of pin location on clevis to the surface that the chamber is mounted to. Write that measurement down in the note pad you are using for this project. Hopefully your slack arm is greater than a 90 degree angle. You will see the importance of this later.

Step Two

Completely remove all air from system and tanks! You don’t want any hoses whipping around when you unhook them. ;-)

Mark your all of your air lines for correct installation later. Remove your DD-3’s, air lines and inversion valve. Pay particular attention to the two hard lines to the inversion valve, one is for the lock port on your DD-3’s, the other if for the emergency port. You will be plugging the emergency line and hooking up the lock port line to the Supply Port on your QR-1C.
If you have spacers between the DD-3’s and mounting bracket, you will not need them to install your new Spring Brake Chambers.

Step Three

Clean the surface of the mounting brackets, make sure they are flat and have no burs. This is also a good time to grease all of the points in your slack adjusters and anything else that needs attention. You’re under there anyway, might as well make the most of it.

Step Four

Now the fun begins. I’m sure that you have read all you can on spring brakes and the installation of them, you are ready to make them fit properly. Right?
Make sure the new spring brakes are in the caged position. As you are tightening the spring cage bolt notice it should be moving in. Now follow the instructions that you read for cutting the rod to the proper length. The length I ended up using was 2 ½” from face of chamber to end of rod.
You should already have the jam nut on the rod. Install the clevis and tighten to specs.
Back off the slack adjuster arm away from the bracket. Makes it easier to install and does not cause any clearance problems.
I suggest to you do one side at a time. Install the spring brake chamber on your clean bracket and tighten nuts to spec. Move the slack arm towards the clevis so you can insert the pin and cotter pin. Now adjust your slack adjuster as you would normally do when you adjust your brakes. At this point you should notice the slack arm is more than a 90 degree angle to the rod. Remember when the service brake is applied the arm and rod should be as close to a 90 degree right angle as possible.
Now go ahead and install the other side, using the same procedures outlined above.

Step Five

You will install the QR-1C in the same location as was the inversion valve.
My relay valve was directly above the old location of the inversion valve. You may have to drill one bolt hole to mount the QR-1C, the other one should work fine. Remove a plug on one Delivery side and install your nylon fitting. Install the other nylon fitting in the balance port on the QR-1C. Slide nylon tube into fitting on relay valve and hand tighten. Then slide the other end in the fitting on the QR-1C. Tighten all fasteners and fittings. Now connect the lock pipe line to the Supply side of your QR-1C, you will need a 90 elbow to do this. Should have been one on the old inversion valve, mine did.

Step Six

Now go ahead and install all of the hoses in the proper location. Make sure there will be no rubbing as they pressurize or from coach suspension movement.

Step Seven

Make sure all connections are tight, cotter pins installed and everything in order.
Now is the time to air up your coach. I used shop air and brought it up to 60 psi. Then got under the coach and listened for any leaks. Now bring up the air to 100 psi and release the Park Brake Valve. Make at least three or four service brake applications. Have someone do that while you go under to look and listen. Watch the action of the slack arms, rods and service hoses. At this time if all is well, check your spring cage bolt, it should be loose, go ahead and remove it and put them in their storage locations on the spring brake.
Now release the Park Brake, you should hear air exhausting from the QR-1C valve at this time. This is when your springs are doing their work to keep your coach from moving.
Make several service and park brake applications, go under coach and double check everything.
Go back under and using a bottle of soap and water, coat all air fittings and look for bubbles.

Step Eight

If you feel comfortable with the installation and know your brakes are working properly, take it for a test ride. I would suggest a short one at first, then crawl under coach and check again. If you have an IR temperature gun, and you take it for a longer ride, stop and take a reading of the rear axle drums. Making sure you don’t have any brake drag.

Congratulations, you have successfully installed and upgraded your rear brake system.

Thanks Wayne, Although I was a bit shaky about doing it, after all is said and done it's really no big deal. I could do it in half the time now, hope I won't ever have to! ;)

I wanted to share with you something I bought in Ensenada Mexico while on a three day cruise out of LA. It is made of Iron Wood and thought it would make a nice addition to our Eagle.

I can't believe it! I found my old website this morning, and it was a stroll down memory lane. I sure saw lots of things I would do different, but it's all good.

I thought I had lost all the pictures and information forever. :shock:

I have saved the pictures, it would only let me save them in bitmap format. I don't know if I can change that or not.

I lost the domain name to some jerk because I didn't see the email to pay up!

http://www.freewebs.com/dreamscapeken/index.htm

CRS has not gotten me yet! :lol: :lol:

This is what Dreamscape looked like when I bought it.

Image

I bought the domain for my new website, it will be available in a few days. It is going to replace the blog name that is in my signature.
It will be called www.uniquebusconversion.com

Don't you love it when stuff works out like that, Paul! That's great that you can have your complete history with the bus now. She wasn't a bad looking ole girl right from the start!

Someone was able to grab my music website quite a few years back. Of course, they tried to sell it back to me for $10,000! Three different foreign companies got it and tried to sell it to me before my server guy was finally able to get it.

Have you heard of the internet archive? There is a company that keeps archives of the entire internet back for years! I was able to get a lot of my old music pictures back by using this. Pictures are not always there, but it is worth a try. It's free too! It's called the Wayback Machine.
http://www.archive.org/index.php
Just type any URL in there and it will give you all the dates that they did backups on the website.

Thanks Dale for the info! I had not heard of an internet archive, so that is good information.

I was able to copy all of the verbage and pictures this morning, what a relief! I will put in my portable hard drive and refer to it.

It was such a good feeling to view it once again! ;)

This is the begining of the process in making the oak dash. Notice how really bad it makes the orginal steering wheel look! :( The gauge panel is removable so I can get to the gauges.

Image

This is where the back up camera monitor will go along with the stereo.

Image

The back of the cabinet is removable, so if something goes south I can get to it.

Image

My wife said to me while we at TBR this year and I quote "When are you going to build the dash?" My reply was "As soon as I have the time". :lol:

Her response when she saw me building the dash, "When are you going to start on the kitchen?". My response was "That's next Honey?" My real feelings were, (When I get finished with the dash you wanted me to build, so don't rush me). :? Sheesh! :? I Love Her anyway! 8-)

Paul Nice job I like the looks of a wood dash. Working with wood is my favorite part of the conversion. Seeing your work makes me work harder on the frame of mine so I can get to the woodwork.
