The importance of brake fluid bleeding cannot be overstated. Brake fluid is the lifeblood of your vehicle’s braking system, and its proper function is crucial for safe and effective braking. When brake fluid won’t come out when bleeding, it can be a frustrating and potentially dangerous situation. In this article, we will explore the reasons why brake fluid won’t come out when bleeding, and provide a comprehensive guide on how to troubleshoot and resolve this issue.

Why is Brake Fluid Bleeding Important?
Brake fluid bleeding is a process of removing air from the brake system to ensure that the brake fluid flows freely and consistently. Air can enter the brake system through various means, such as when the brake pads wear out, or when the brake lines are damaged. When air is present in the brake system, it can cause the brake fluid to become contaminated, leading to reduced braking performance and potentially even brake failure.
Bleeding the brake system is a critical step in maintaining the health and safety of your vehicle’s braking system. It is recommended to bleed the brake system every 30,000 to 50,000 miles, or as recommended by the manufacturer. Failure to bleed the brake system regularly can lead to a range of problems, including:
- Poor braking performance
- Reduced brake pedal travel
- Brake pedal sponginess
- Brake failure
Why Won’t Brake Fluid Come Out When Bleeding?
There are several reasons why brake fluid won’t come out when bleeding. Some common causes include:
Air in the Brake Lines
Air can enter the brake lines through various means, such as when the brake pads wear out, or when the brake lines are damaged. When air is present in the brake lines, it can cause the brake fluid to become contaminated, leading to reduced braking performance and potentially even brake failure.
Clogged Brake Lines
Clogged brake lines can also prevent brake fluid from coming out when bleeding. Clogged brake lines can be caused by a range of factors, including corrosion, mineral buildup, or debris accumulation. (See Also: Which Peddle Is the Brake? Essential Cycling Tips)
Incorrect Bleeding Procedure
Using the wrong bleeding procedure or failing to follow proper bleeding techniques can also prevent brake fluid from coming out when bleeding. It is essential to follow the manufacturer’s recommended bleeding procedure to ensure that the brake system is properly bled.
Brake Fluid Contamination
Brake fluid contamination can also prevent brake fluid from coming out when bleeding. Brake fluid can become contaminated with air, water, or other substances, which can affect its ability to flow freely and consistently.
How to Troubleshoot and Resolve Brake Fluid Not Coming Out When Bleeding?
When brake fluid won’t come out when bleeding, it is essential to troubleshoot and resolve the issue promptly to ensure the safety and effectiveness of your vehicle’s braking system. Here are some steps to follow:
Step 1: Identify the Cause of the Problem
The first step in troubleshooting and resolving brake fluid not coming out when bleeding is to identify the cause of the problem. This may involve inspecting the brake lines, checking for air in the brake lines, and ensuring that the bleeding procedure is being followed correctly.
Step 2: Bleed the Brake System
Once the cause of the problem has been identified, it is essential to bleed the brake system to remove any air or debris that may be present. This may involve using a brake bleeding kit or consulting a professional mechanic.
Step 3: Check for Brake Fluid Contamination
After bleeding the brake system, it is essential to check for brake fluid contamination. This may involve inspecting the brake fluid for signs of air, water, or other substances, and replacing the brake fluid if necessary. (See Also: When Your Brake Pedal Goes to the Floor? What To Do Next)
Step 4: Test the Brake System
Once the brake system has been bled and the brake fluid has been checked for contamination, it is essential to test the brake system to ensure that it is functioning properly. This may involve driving the vehicle and testing the brakes to ensure that they are functioning correctly.
