Changing Brake Fluid: A Practical Guide

Introduction

This guide provides information on how to change the brake fluid in your vehicle. It covers fluid quantity considerations and the proper bleeding sequence.

Problem

Maintaining clean brake fluid is essential for optimal braking performance. Over time, brake fluid can absorb moisture, reducing its effectiveness and potentially leading to corrosion within the braking system.

Solution

  1. Fluid Quantity: It is generally recommended to use at least 1 liter (two 500ml containers) of DOT 3 brake fluid to ensure a thorough flush of the system. Some users have found they need 1.5L.
  2. Bleeding Sequence: When bleeding the brakes, start with the wheel furthest from the brake master cylinder and work your way to the closest. This is generally:
    • Rear passenger side
    • Rear driver side
    • Front passenger side
    • Front driver side
  3. Procedure: This can be completed by repeatedly opening the bleed valve at each wheel while pressure is applied to the brake pedal. You will require an assistant to pump the brakes on your instruction.

Relevant Parts

  • DOT 3 Brake Fluid (Minimum 1 liter, two 500ml containers recommended)
