What is a push rod and slack adjuster

A push rod and a slack adjuster are components of an air-brake system. The push rod is a lever attached to the brake chamber, connected to the brake camshaft, which provides the mechanical link between them. The slack adjuster is responsible for maintaining the brakes in proper adjustment during normal use. It is located on the axle housing near the wheel and converts the straight line pushing action of the pushrod into a rotation movement that ultimately applies or releases the brakes.

What is the push rod secured to the slack adjuster with?

The slack adjuster is secured to the push rod with a snap ring. This snap ring holds the adjuster in place and prevents it from moving more than one inch from where it is attached. Inspecting this connection is important to ensure that the brakes are working correctly and safely. To check the connection, it is recommended to pull the slack adjuster and measure from the fixed point to the mark on the push rod. If the adjuster moves more than one inch, it should be secured with a snap ring.

What is the function of a slack adjuster?

A slack adjuster is a vital part of an air-brake system and is located on the axle housing near the wheel. Its purpose is to maintain a consistent distance between the brake shoes and drums. This helps to ensure that the brakes are working efficiently and safely. When the brakes are applied, the slack adjuster is activated, pushing out the rod which connects it to the actuator. The automatic slack adjuster is designed to self-adjust for wear on the brake lining and drum, helping to ensure that a sufficient braking force is created when needed. 

What are the two types of slack adjusters?

When it comes to slack adjusters, there are two types to choose from: manual and automatic. Manual slack adjusters are typically found in older vehicles and require the user to manually adjust the brakes themselves. Automatic slack adjusters, on the other hand, are easier to use and can be found in newer vehicles. To find the right type of slack adjuster for your vehicle, it is important to measure the arm length of the slack adjuster and take into account the type of brakes that you have installed.

Why is pushrod suspension better?

Pushrod suspension is seen as a better option for many racing cars due to its advantages in terms of aerodynamics and response. Firstly, the pushrod suspension is more efficient in terms of air stream, as the damper unit is not present. This reduces the unsprung mass and allows for better performance. Secondly, it is much more difficult to make setup changes with a pullrod suspension, as a mechanic will have to lie down underneath the car and work on it. Thirdly, push rod suspensions are much more rigid and give better response for low travels compared to double wishbone suspensions.
