Brake Fluid

At the suggestion of RAM, one of the more knowledgeable MV Experts in the US, We are just two old Farts that have been around GI Trucks a bit, and kept our eyes open, it was suggested I flush the Brake Systems of my 2-1/2 Ton Trucks with Power Brakes. I was surprised at the brown sludge that came out. It is now a 3 year ritual. Whether you use DOT-3 Conventional, or DOT-5 Silicone, you will have similar crud. These systems "breathe" and are subject to condensation, and it has to settle somewhere. Yes, silicone Brake Fluid can be a victim of condensation. Think about it, where is the water going to go? It will puddle in the low spots in the system. Same goes for your Jeeps, too.

Great Tip Joel...

That is true for Currently produced passenger cars and trucks as well.

If you look at your owners manual it will "suggest" that you have the brake system flushed every 2-3 years to get rid of the brake fluid sludge.

Having been in the auto business for over 30 years and an auto manufacturers field service rep for over 25...no one does this.

Hey...its only money.

One thing to remember when changing the fluid is where the junk is going. By that I mean, do you open the bleeders and run the fluid thru the wheel cylinders. If you do, because the bleeder is at the top, you will deposit some sediment into the wheel cylinder that most likely will not come out with the bleed cycle. Likewise, if you do a reverse bleed/clean out, you don't want junk going into the master cyl either.

I will be doing my cargo this spring and I plan to disassemble the wheel cylinders (on the truck) and pressure bleed from the master. That way I can clean all the junk out and inspect the rubbers and cylinders at the same time.
