How To Replace Air Brake Chambers

How To Replace Air Brake Chambers

1. CAGE SERVICE SPRING. Park your truck or trailer on a level surface, chock the wheels and apply the parking brake. Position a locking pliers against the mounting housing of the failed air chamber and securely clamp it on the pushrod to prevent movement. Release the parking brakes.

2. CAGE PARKING SPRING. Remove the caging tool, also called a T bolt, from the storage tube on the Brake chamber . Remove the plastic inspection plug from the front of the spring-brake’s dome, or pressure cap. Shine a light inside the dome to locate the spring’s caging-tool hole. Insert the tool into the hole and turn it slightly until the T end hooks into the spring’s corresponding notches. Slip a flat washer over the tool’s bolt end and thread on a nut until it rests against the washer. Do not tighten the nut with a wrench unless you’re unable to use the vehicle’s air pressure for the caging process. When the spring is fully caged, the bolt should protrude about 31/4 inches from the dome. If air pressure is unavailable, you’ll need to crank down the nut with a wrench. In this event, do not exceed 35 pounds-feet of torque once the spring is caged. Reapply the parking brakes.

3. REMOVE AIR HOSES. (This procedure is unnecessary if you’re simply installing a new service diaphragm or mounting housing.) Mark the hoses to ensure proper reassembly, then loosen and remove them. Often the hoses will have a swivel fitting at one end and a crimped-on pipe fitting at the other. Remove both hoses at their swivel fittings. If either of these fittings is permanently bonded with corrosion, however, cut and replace the attached hose.

4. REMOVE SPRING-BRAKE CHAMBER. (This procedure is unnecessary if you’re replacing the mounting hosing and spring brake chamber.) Loosen the clamp holding the spring brake chamber to the mounting housing and tap it free with a hammer. Lift the chamber out of the clamp.

5. REMOVE MOUNTING HOUSING. (This and the following procedure are unnecessary if you’re only replacing the spring-brake chamber.) Pull the pin(s) connecting the pushrod clevis to the slack adjuster. Remove the nuts holding the mounting housing to the axle bracket. Use a steel brush to scrub accumulated corrosion and dirt from the bracket’s mating surface, then apply a coat of rust-inhibiting paint.

6. PREP AND INSTALL NEW MOUNTING HOUSING. While the old service spring is still caged, measure the pushrod length between the clevis and the outer surface of the mounting housing. Cage the new service spring by placing it on the floor – open side down – and standing on the housing while attaching a locking pliers to the pushrod. A jam nut should be installed on the new pushrod. Spin the nut down near the housing’s surface. Cut the pushrod so its length matches that of the old one. Use the jam nut to open any damaged pushrod threads. Install a new clevis and secure it with the jam nut. Mount the housing to the axle bracket and torque the nuts to the manufacturer’s specs. Connect the clevis and slack adjuster, and make sure they form a 90-degree angle when fully applied.

7. PREP AIR CHAMBER MATING SURFACE. (This and the following procedure are unnecessary on sealed chambers or complete kit replacements.) Inspect the mating surface of the chamber being reused. Use a steel brush or Emory cloth to scrub accumulated corrosion and dirt from the mating surface. Always replace clamps, bolts and diaphragms that have been in service more than a month, regardless of their appearance. These items are cheap and not worth the risk of failure.

8. INSTALL SPRING BRAKE CHAMBER. Loosely connect two band-clamp halves with one bolt. Lay a new diaphragm bowl-like inside the spring-brake chamber’s open end. Keeping the diaphragm in place with your fingertips, center the chamber on the mounting housing. Drape the clamp over the top of the chambers’ mating surface and gently tap it down. Repeat the procedure with the clamp’s bottom half and thread in its second bolt. Rotate the chamber for optimum access to the air-hose ports and fittings. Closely inspect the clamp to ensure it’s properly positioned all around the chamber, then tighten the bolts equally – moving from one to the other – until the clamp ends are 1/4 to 1/2 inch apart. Apply no more than 25 pounds-feet of torque to them.

9. APPLY AIR, UNCAGE AND LISTEN. Brush a thin coat of thread sealer on each end of your hose fittings and attach them to the proper ports. Release the parking brake and remove the caging tool from the air chamber’s dome. With an assistant using the brake pedal to apply 80 to 100 pounds of air pressure, remove the locking pliers from the pushrod. Listen for leaks. Lacking a helper, you can squirt soapy water on the mating surface then apply pedal pressure. Any leak will quickly generate a lot of bubbles. If the diaphragm hasn’t sealed, you’ll need to repeat steps 1, 2 and 8, locating the trouble spot in the process. Finish by installing the dome’s dust cap and securing the air hoses with plastic ties so they don’t rub against any hard surfaces.

Adjusting a Bendix Air Governor

Adjusting the Bendix D2 governor just takes a 7/16 wrench and a screwdriver. The unloading pressure for the typical air brake system is 120 psi but it can be higher up to 130 psi without a problem. Anywhere in the middle is good in my book. This is an easy adjustment as you can see in the video.

The adjustment is touchy and to increase unloading pressure you turn the screw clockwise and counter clockwise to reduce pressure. When the air breake valve compressor reaches it’s limit the governor is there to unload it preventing air pressure from building too high. For you seasoned mechanics this is very elementary information but for those who didn’t know how to make this adjustment then I hope this info helps.

The unloader is located at the air dryer and where the air pressure is directed to when the governor setting is reached. There is an unloader port at the governor that is routed by an air line to the air dryer when 120 psi is reached. What this does is unload all the accumulated oil and moisture that has settled at the bottom of the dryer base.

At 120 psi there is an audible sound of exhaust shooting out the bottom of the dryer housing. This indicates to the operator or the tech working on the air system what pressure the governor is set at. The air dryer needs to be serviced on a regular schedule to clean out the contaminants that accumulate over time.

We service our air dryers every 2 years which includes a dessicant filter and unloader service kit. Also included is a heater that prevents the bottom of the dryer from freezing in the winter time. The AD9 air dryer can be serviced quickly in-frame using a replacement unloader valve assembly that is secured by three bolts. The filter is removed by removing the bottom section of the dryer.

How Long Will U Leaf Springs Last?

Unlike the oil change, there aren’t a set number of miles that one’s truck needs to reach before needing to replace the leaf springs. The life span of leaf springs usually will depend on the wear and tear. In truth, some trucks never need to have their leaf springs replaced while others will wear out muck quicker. The leaf springs that hardly ever need replacing will most likely be the trucks for casual use.

Heavy equipment like farm vehicles, snow plows, and recreational vehicles are going to be the kind leaf springs that need frequent replacement. Again, this depends on the type of task and even still, it is difficult to determine exactly when one should replace the leaf springs on their work equipment. However, there are some tell tale signs that your vehicle will give you to let you know that it might be needing a leaf spring replacement.

Signs That Indicate Your Leaf Springs Are Worn Out

If your existing leaf springs are cracked.

This is an obvious one, but it requires a routine inspection. If you are operating heavy equipment or using your truck to haul overbearing loads, it is highly recommended to conduct a routine inspection on your vehicle. It can be weekly, monthly, or quarterly depending on how much work is put on the vehicle. You can also check for yourself.

Leaf springs are located near the axle of a truck attached directly to the frame. They are typically found on the rear axle but can also be used for front independent or solid axle suspensions as well.

For flatbed trucks, the rear end sags.

Since leaf springs are all about suspension, another obvious sign for leaf spring replacement is noticing when or if the back of your truck sags without any additional weight. While it is normal for a vehicle to bow a little from extra-added weight, one should take heed when the bow is present without any additional pressure. This usually means that the existing leaf springs are worn and/or broken and will not be able to successfully hold any more weight without damaging the suspension.

Many people carry a lot of weight on the rear and your springs just might not be designed to carry enough heavy weight without bottoming out or sagging more than you’d like. We offer heavy duty leaf springs to fix this problem which can handle a bigger load while keeping the rear of the truck higher or level with the front while loaded.

Your vehicle is leveled.

This might sound strange, a leveled truck needing leaf spring replacements, but it’s true. Although it is normal for most vehicles to be leveled, trucks are designed to sit up a little higher in the back in order to better carry the weight of additional loads.

What to know When Replace Yourk Ford F250 Truck Leaf Springs

Not every Ford truck is built the same, you know that, but did you know that even on the same model Ford Truck you can have many different load capacities for your leaf springs? Not everyone uses his or her truck the same way. So it’s important to know what the capacity of your truck’s leaf springs are before you start to load your truck bed. By taking this precaution, you can avoid overloading your leaf springs and causing major damage to your truck.

For Leaf Spring Fit Truck Category Matters

At New Truck Spring, we realize that the fit of the leaf spring depends on the truck, so we carry leaf springs for many of the different varieties of Ford trucks. We can supply leaf springs for the F100, F150, F250, F350, F450, F550, Ranger, Bronco, Bronco II, Excursion, Explorer, Mountaineer, and Navajo.

However, even within some of these varieties, the model year of the truck can make a big difference. For instance, the F350 has had four different leaf springs sizes over the years. The springs were the same between 1973 – 1979, 1980 – 1997, 1999 – 2007 and 2008 – 2014. As experts in the field of suspension products we can ask the right questions to help make sure you choose the right product for your vehicle.

How Different Can the Capacity Be for Each Truck Type?

Take for instance the Ford F350 for model years 2008 – 2014. We carry four different model leaf springs that will fit the rear suspension on this truck. All measure 33 ¼” X 33 ¼” with a width of 3”, but the spring capacities are 2,700 lbs., 3,600 lbs., 4,400 lbs. and 5,000 lbs.

The two lower capacity springs have 5 leaves and the two larger capacity springs have 6 leaves, to help take the extra

Hard to Find Leaf Springs for Classices Cars at New Truck Spring

You may have heard of the old saying, “They don’t make them like they used to anymore!”

In part, this is quite true when it comes to the automotive industry. Earlier cars were considered a luxury for only the rich, and they weren’t mass-produced on the level that they are today. Resources were plenty and the demand for such vehicles for those who could afford it was substantial, but for today’s numbers, the ownership of classic cars are still quite low.

As a result, the materials used back then were heavier, bulker, and today—expensive! What’s more, when it came to the smaller parts of the vehicle like the suspension system, inventors were still in the earlier stages of discovering what makes up a smoother ride—and in essence, still are today!

The Challenge of Finding Replacement Parts

Whether you want to refer to these earlier cars as old or classic, the truth somewhat remains that indeed, they don’t make them like they used to! So for car collectors and classic car owners who may have received their treasure through an inheritance, an auction, or the sheer luck of stumbling upon it in a junkyard, chances are you’re probably having a challenge finding replacement parts for your leaf spring.

The chances are quite slim that you’ll find leaf springs for a classic car at your local automotive store. Even if you’ve gotten by with combing junkyards for parts, when it comes to classic cars, you won’t have much luck. Even if you contacted the manufacturer, the response that you’ll most likely get is that particular model is obsolete and yes, they don’t make them anymore!

So if the manufacturer doesn’t make leaf springs for their earlier models, and finding replacement parts makes finding a needle in a haystack look easy, what exactly are your options? You could, like most ex-classic car owners, scrap the parts out and sell the material, or you can call New truck Spring, a leaf spring replacement and manufacturing company in New Century, KS.
