What is the adjustment stroke limit for a 24 series brake chamber?
Stroke limits in the regulation for Type 24L and Type 30LS are 2 inches and 2 1/2 inches, respectively. The table below shows pushrod stroke measurements recorded on three occasions.
How do I know if my brake chamber is long or short stroke?
The type of brake chamber, in terms of its stroke, is determined by looking for visual identifiers that indicate it is a long stroke chamber. The absence of a recognizable long stroke marking requires the inspector to deem the brake chamber to be a standard type and not a long stroke type.
What is the maximum stroke travel of a standard brake chamber?
2½ inches
The most common type of air brake chamber used on trucks and trailers is the Type 30. These chambers have a maximum available stroke of 2½ inches (65 mm). A long stroke Type 30 is designated Type 30LS, and has a maximum available stroke of three inches.
What is a Type 24 brake chamber?
Type-24/24 air brake chamber has a fully threaded shaft for maximum adjustability and includes mounting hardware, clevis and cotter pin. Spring brake chamber is permanently sealed for increased safety. Includes spring brake cage bolt. Includes clevis for attachment to slack adjuster.
When brake chamber push rod stroke exceeds the adjustment limit?
Inspection of brake adjustment at each wheel should be performed with air pressure between 621 and 690 kPa (90 and 100 psi ), the engine shut off and service brakes fully applied and spring brakes must be released. When pushrod stroke exceeds the adjustment limit of the brake chamber the brake is out of adjustment.
How is brake chamber stroke measured?
To measure brake stroke, bleed the air system down to between 90 and 100 psi, and note the center of the clevis pin’s position on the ruler. Next, either have someone fully apply the brakes and hold the pedal down, or wedge the brake pedal in the fully applied position.
Which is better short stroke or long stroke?
A long bore engine, as the name suggests, has a longer cylinder. These engines reach their peak torque at a lower rpm when compared to a short-stroke engine. These are more efficient engines and are moreover used in commercially selling cars.

What is the maximum push rod travel allowed?
Pull the chamber push rod out to its limit by pulling on the slack adjuster arm or by prying with a short bar. If push rod travel is more than 3/4 in. (19 mm), brakes MUST be adjusted.
Can a truck driver adjust his own brakes?
Guidance: Yes. A driver is permitted to perform brake adjustments at a roadside inspection providing they are done under the supervision of a qualified brake adjuster and the carrier is willing to assume responsibility for the proper adjustment.
What determines maximum push rod stroke adjustment limit?
It is the size of the brake chamber that determines the maximum allowable push rod travel. The outside diameter of the brake chamber must be measured, and than you can determine the maximum allowable push rod stroke.
What are the dimensions of a Type 24 long stroke brake?
