3) Flush the calipers/wheel cylindersĮach brake calliper/wheel cylinder has a bleed nipple on the back. What brake fluid do you need for your car? Consult your Haynes manual or your car's manual to make sure you use the correct-specification fluid. If the container is open, the fluid will absorb moisture from the air. Only use new fluid from a sealed container. Once that’s done, you need to fill the master cylinder back up with new brake fluid, right up to the MAX line. Now you need to get a lint-free cloth and clean out any debris that might be in the reservoir. The best way to tackle this is with the car up on axle stands, with all four wheels removed. Once you’ve removed as much as you can, it’s time to go to the brakes themselves. Take the cap off the brake master cylinder and, using a syringe or something similar, remove as much of the old brake fluid as possible. There are ‘one-man’ bleed kits, but they’re seldom as effective as having a friend pressing on the pedal for you. Before we do, there is one caveat: get a second person to help you. However, the general procedure remains the same, which we’ll go through now. While some fluids are technically interchangeable, it’s always best to make sure you’re filling your braking system with the right stuff.Įach car will be ever so slightly different, or subject to its own intricacies. Your Haynes manual will guide you through the process of how to change the brakes, and it will also cover what brake fluid your car needs. Take the cap of the brake master cylinder and smell the fluid, if it smells burned, or if it’s exceptionally dark in colour, it’s time to change it. In fact this can also happen when the car is driven enthusiastically (on a race track, for example), where the brake fluid can overheat and cause something called brake fade, where the hydraulic action of the fluid is less effective. This can happen after a period of prolonged braking, such as descending a long, steep hill. The pedal becomes ‘soft’ and the brakes no longer work. If the fluid can be compressed, it can no longer act upon the brakes when the pedal is depressed. If the fluid boils, lots of air bubbles form, which will allow the fluid to be easily compressed. If there is a fault with your braking system at any point, and the fluid gets too hot, you can boil it. The lower the fluid boiling point, the easier it will boil. So, logic would dictate that the longer you leave it, the less effective it will become. The more moisture that becomes a part of the brake fluid, the lower the boiling point of the fluid becomes. The problem with brake fluid is that it’s hygroscopic. When you press the pedal, you act upon the fluid, which then in turn acts upon the brakes. Without this, your brakes won’t do anything. Yes, there is the matter of discs and pads, but don’t go forgetting the fluid. However, they’re only any good if they’re maintained properly. And that’s good, because hydraulic braking systems are commonplace and also the most effective. Unless you drive something really, really old, your car is going to have hydraulic brakes.
