Brake Fluid Replacement in Morden

What is brake fluid?

Car brakes on your car use fluid pressure to work. When a car’s brake pedal is pushed, a plunger in the brake’s master cylinder pressurises the brake fluid that resides in the hoses and pipes to make the other components of the braking system move.

How long does brake fluid last?

This varies from car to car, but most manufacturers suggest booking a brake fluid replacement at least every couple of years. Although the fluid is in a sealed system, moisture can still find its way in. It corrodes components over time and decreases the temperature at which the fluid is supposed to boil.

Furthermore, as the internal components of the braking system wear out, debris contaminates the fluid, jamming everything up. All of this impacts on how well the brakes function, particularly in constant stop-start traffic with heavy braking and can lead to expensive brake repairs.

What are the possible signs that a car needs new, or more, brake fluid?

• If the brakes on a car feel in any way as though they are not functioning correctly.
• When the car’s brakes are spongy when pressed.
• When fluid is new, it has a light amber colour to it, so that is what to look out for.
• As the light amber fluid darkens, which is a sign of contamination, the need to change it increases.
• If the fluid ever becomes darker than brown, or even black, then it should be changed immediately.

How long does it take to change brake fluid?

• The fluid can be easily replaced in around 15-30 minutes, depending on the vehicle.

How much does brake fluid cost?

• The fluid is relatively inexpensive, certainly compared to the cost of replacing a corroded master cylinder, so it’s important to keep an eye on it.
• The cost can vary from vehicle to vehicle but should be less than £50.
