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.

Replaces Suspesion parts for the popular toyota tacoma

Unfortunately, the leaf springs on Toyota Tacoma's tend to ware out, crack, and break. Whether it is because of the factory spring construction or the amount of use the trucks get by their active owners, the broken springs need to be replaced. If your tacoma leaf spring needs new suspension parts you're in the right place. We offer right and left springs separately, as they are sometimes different in tacoma's to compensate for driver-side only traveling as well as fuel tank weight. However, the difference is normally only in the arch and is negligible in certain cases where springs are superseded and will fit with parts like this tacoma shackle.

Tacoma has been around for so long it often becomes necessary to replace worn suspension parts as part of a routine maintenance. Keeping your suspension working properly is crucial to not only having a smooth ride as you go over bumps and imperfections in the road, but it is also important to maintain the load capacity of your truck and prevent damage to the chassis.

Finding the Right Product is a Matter of Concern

Since the Tacoma has been around for so long, it’s no surprise that the model design has changed from time to time, including the fit of the suspension system on the truck. In fact, the leaf springs alone have changed five times for the Toyota Tacoma, so it’s important that you get the right leaf springs for your particular model. The five model year groupings are:

1. 1995-1997
2. 1998-2000
3. 2001-2004
4. 2005-2011
5. 2012-2014

On top of the model year, the specific model of truck will also dictate what leaf springs you need. For instance, in the 1995 – 1997 models, there are four types of rear wheel leaf springs available: the factory default 4 X 4 with 4 leaves, heavy-duty 4 X 4 with 4 leaves, the factory default 4 X 4 with 3 leaves, and the 2-wheel drive model with 3 leaves. So, as you can see knowing the model of your Toyota Tacoma is an important factor when choosing proper suspension parts.

What are some of the most popular leaf springs for the Toyota Tacoma?

1.2005-2011 Toyota Tacoma Prerunner 2wd 2/1 Leaves

2.1984-1988 Toyota Pickup and Chassis Cab 4wd 3/1 Leaves

Torsion Springs are utilized in products

Torsion Springs

Torsion Springs are utilized in products that require a resistance to or application of torque. Once a load is applied to the legs, coil spring deflect and elongate resulting in an angular return force. Torsion springs are closely wound with various leg configurations, such as straight legs and multiple leg bends. The direction of the wind, clockwise or counter-clockwise, is determined by the application.

Some important factors to consider when offering torsion springs include:

(1)Material Type
(2)Wire diameter
(3)Outside/ Inside diameter
(4) Frequency of rotation
(5) Torque
(6) Winding direction     Right hand (counter-clock wise)  or  Left hand (clockwise)
(7)Surface treatment
(8)Number of coils
(9)Length of leg #1an #2
(10) Range of operating temperature
(11) Maximum wound position in number of turns or degrees from free position
(12) Length of leg ends
(13) Relationship of legs
The  relative relationship between the legs of torsion springs at the tangent point in the free position measured in degrees.
