Hey guys what is the reason flushing brake system? Evey three yrs, as dealer suggested? And replacing brake rotors when they are thicker than my glasses ( my glasses are pretty thick) do they cut rotors at mb or is it better to just replace them????? Just a question???? Thanks

 

the recommendation is every 2 years for brake fluid. The system is not sealed and brake fluid is hygroscopic, which means it absorbs water. This water lowers the boiling point of the fluid, resulting in quicker and more pronounced brake fade. It can also result in rusting/corrosion in the brake system, such as the MC, caliper pistons and lines.

MB will not recommend cutting the disks, but so long as you are above teh minimum thickness, you can do it and it should be ok.

 

brake fluid breaks down from constant heat (boiling point) to the point moisture gets in and it doesn't do its job anymore and also can cause corrosion in the lines from water in it, bad break fluid will give you a soft pedal over time after it starts to break down which could effect your braking distance.

 

beat me too it, youuu your gooddd you!

 

Ok makes sense i will get it done then thanks guys

 

Can there be any complications from doing a flush?

I haven't changed mine in my 4 years of ownership now..The car stops very well and the braking is firm as ever.

 

Take the requirement for flushing the brake system as gospel. I had a ford F250 diesel that the original owner never changed the brake fluid on (it was 10 years old when I got it). Running in the city at 20mph, I put on the brakes and had the pedal go to the floor. Both brake lines broke off at the master cylinder causing me to plow ever so slowly into the pickup truck in front of me. Reason, the lines where corroded from the inside. If you looked only at the outside, they looked almost new.

Change it....cheap insurance.

 

not really. If you use a powerbleeder, its almost idiotproof so long as you don't let the MC run dry. If you use the manual pumping the brakes method, place a piece of wood beneath the pedal so that you don't let the MC piston travel further than normal, which can cause a torn seal.
