Brake Fluid

RP Automotive Services are seeing more and more often cars that have been regularly serviced but not had the brake fluid checked for moisture.
Most car manufacturers specify brake fluid should be replaced every 2 years. This is because brake fluid absorbs moisture which in turn dramatically reduces the fluids boiling point.
The heat caused by friction when the brakes are used is considerable and when there is 3% or more moisture in the brake fluid this will have a significant effect on the braking efficiency of the car by boiling the fluid under prolonged or


heavy breaking .
We check the moisture levels as part of the routine service schedule. Please check with your garage or mechanic that this is also part of their service.
It only takes a couple of minutes and could save lives. Frequently the customer who has had their car serviced at reputable garages are surprised when they see the results of the brake fluid test.
Car owners put a lot of trust into the hands of garages and mechanics, being professional means that we don’t just make sure the pads/shoes are good and top up the fluid it means checking the system this includes fluid moisture levels.

  1. I agree with your advise, but someone says that brake fluid should be replaced when brake fluid color changes to completely black color.

    • No not at all who ever is telling you that is wrong.

    I am glad i read this blog! My mechanic you manages our fleet has never mentioned that it needs to be regular. Will cost us more but is definitely worth it. Thanks!

    • I hope your mechanic will in future follow the recomended service schedules for your vehicle.

    Hi Richie.
    You may remember I left a comment about how our mechanic didn’t know how to put out the service light. Maybe this is something I should chech too 🙂

    • Dale please check that the proper service schedule is being followed.

    Really informative. I was not aware that changing the brake fluid must be a regular procedure.Thanks a lot!

    • Thanks for your comment Adam,
      The general rule of thumb is change brake fluid every 24 months, the brake fluid should be tested every service though.

  6. Something that I dare say that many people are not aware of. Your life could depend on your brakes working properly and I’m stagered that many garages are not checking this.
    Thank you for a very informative post.

      I agree, it’s such a simple test it makes no sense at all not to do it as part of the service
