Brake Fluid Change
Regular Brake fluid change, also known as brake bleeding, or a brake fluid flush, is an essential part of car maintenance to keep the braking system operating safely and as expected.
Generally, brake fluid needs to be changed every 24 months or 24,000 miles, with this forming part of most vehicle manufacturers' routine service schedules.
To renew brake fluid properly requires specialist equipment, which forcibly bleeds the entire braking system under high pressure, with the fresh brake fluid forcing out the contaminated old fluid.
Our highly trained vehicle technicians will ensure this procedure is completed on each brake fluid circuit individually, with high-grade brake fluid in accordance with the vehicle manufacturer's specifications.
Why does brake fluid need changing?
Your brake fluid connects the brake pedal you press with your foot to the brake pads on each wheel that stops your car using hydraulic pressure, so its role in the braking system is crucial.
Much of the intense heat generated by brake components when stopping is transferred to the brake fluid, meaning it must have an extremely high boiling point, over 200°c, to prevent it from turning into a gas when the brakes are applied.
If brake fluid were to boil, the brake pedal would simply compress the vapour in the brake lines rather than transfer the hydraulic pressure to the brakes at the wheel, preventing the brakes from operating.
The issue is that brake fluid is naturally hygroscopic, meaning it attracts moisture from the atmosphere. This means over time, the percentage of the water in your brake fluid will increase, significantly lowering its boiling point and decreasing your car's braking ability.
That is why almost all vehicle manufacturers recommend replacing your brake fluid every 24 months to ensure the boiling point remains high and the car's barking force is maintained.
