I have a 1998 gmc yukon. I was told that my break fluid has been contaminated. I was wondering how this could have happened and what is the solution to repairing this problem. I was told the entire breaking system needs to be replaced??

Some one would have had to put something other than DOT 3 brake fluid. Try and flush out with new fluid bleed at wheel till clear new fluid comes out

Brake fluid should be changed like the other fluids in your car.
* In general, the recommended service interval is approximately every 30,000 miles. Be sure to check the intervals recommended by your vehicle’s manufacturer.
* Moisture and contaminates can build up in brake fluid, which can harm the brake system and cause brake failure.
* Contaminated brake fluid will become corrosive. Over time brake fluid will eat away at rubber components within the braking system.
