Brake Fluid - test tube torcher test 2.0 - Early viewing
Added 2018-11-15 02:14:22 +0000 UTCWe test dot 3 brake fluid once again, but not exactly the same way we did it for the first time. Thank you again everyone supporting us on Patreon.

I had that exact thing happen to me. I remember one day in my driveway pressing the pedal and got a mushy feel. I engaged the e brake and then had a neighbor get in the car and push the pedal down to find that the line had burst. At the time the car was 10-12 years old. I can't help but wonder if part of it was because the car was originally bought purchased in Ohio and if the road salt wasn't a contributing factor. Either way, I have become very cautious when changing certain fluids (brake and trans fluids in particular). This is especially true if I don't know the full vehicle history.

2018-11-15 20:26:44 +0000 UTCThe fact that behavior was different is caused by 4 years of the fluid absorbing moisture try this with a fresh bottle of fluid and the result will change.

That said, I have had stock brake fluid in cars 20 years old. Is it working at maximum capability? No, but at 20 years old you are likely to burst one of the brake lines at the wheels/axle and be changing the fluid anyway. Remember to be careful if changing out brake fluid on cars with anti-lock brakes (almost every car out now).

2018-11-15 03:23:44 +0000 UTCThe reason for changing brake fluid is due to it's absorbing water which lowers the boiling point, and causes corrosion in the brake system.
