When it comes to ensuring the safety of your vehicle, one of the most critical components is the brake chamber. A brake chamber is a crucial part of the braking system, responsible for amplifying the brake pedal’s movement to apply pressure to the brake shoes or pads. However, a common issue that can arise is back feeding, which can compromise the entire braking system. Back feeding occurs when the brake chamber’s output pressure is greater than the input pressure, causing the brake shoes or pads to move in the opposite direction of the intended movement. This can lead to reduced braking performance, increased stopping distance, and even complete loss of braking capability. In this article, we will explore the importance of checking for back feeding in brake chambers and provide a comprehensive guide on how to do so.

Why is Back Feeding a Concern?
Back feeding can occur due to various reasons, including improper installation, worn-out or damaged components, and incorrect adjustment. When the brake chamber is not functioning correctly, it can cause the brake shoes or pads to move in the opposite direction, leading to reduced braking performance. This can be especially hazardous on slippery or wet roads, where every second counts. Moreover, back feeding can also cause excessive wear on the brake components, leading to premature failure and costly repairs. It is, therefore, essential to identify and address back feeding issues promptly to ensure the safety and reliability of your vehicle.
Signs of Back Feeding
Before we dive into the process of checking for back feeding, it is essential to understand the signs and symptoms of this issue. Some common indicators of back feeding include:
- Spongy or soft brake pedal feel
- Increased stopping distance
- Brake pedal vibration or pulsation
- Brake noise or grinding
- Unusual brake wear patterns
If you notice any of these signs, it is likely that your brake chamber is experiencing back feeding. It is crucial to address this issue promptly to prevent further damage and ensure the safety of your vehicle. (See Also: What Is the Electric Parking Brake? A Safe And Easy Guide)
How to Check for Back Feeding
Checking for back feeding is a relatively straightforward process that requires some basic tools and knowledge. Here’s a step-by-step guide to help you identify and address back feeding issues:
Step 1: Inspect the Brake Chamber
The first step in checking for back feeding is to inspect the brake chamber for any signs of damage or wear. Look for any cracks, dents, or corrosion on the chamber’s body or components. Check the chamber’s seals and gaskets for any signs of wear or damage. If you notice any damage, it is recommended to replace the chamber to prevent further issues.
Step 2: Check the Brake Chamber’s Adjustment
The next step is to check the brake chamber’s adjustment. Make sure the chamber is properly adjusted to ensure the correct amount of pressure is applied to the brake shoes or pads. Consult your vehicle’s repair manual for the recommended adjustment procedure. If the chamber is not adjusted correctly, it can cause back feeding and compromise the braking system.

Step 3: Check the Brake Pedal’s Free Travel
Another important step is to check the brake pedal’s free travel. The free travel refers to the distance the brake pedal moves before the brake shoes or pads start to engage. If the free travel is too long, it can cause back feeding and reduce braking performance. Consult your vehicle’s repair manual for the recommended free travel specifications. If the free travel is excessive, it may be necessary to adjust the brake chamber or replace the brake shoes or pads.
Step 4: Check the Brake Chamber’s Output Pressure
The final step is to check the brake chamber’s output pressure. This can be done using a pressure gauge attached to the chamber’s output port. Compare the output pressure to the recommended specifications for your vehicle. If the output pressure is excessive, it can cause back feeding and compromise the braking system. In this case, it may be necessary to adjust the brake chamber or replace the brake shoes or pads.
