How many of you do this?

I do....brake fluid is sooo fun to clean up! LOL.

It's really simple to do, you will need an extra foot up in the cab to press and release the brake pedal while you loosen and tighten the bleeder valves. Takes maybe 15 to 20 minutes. Might as well do the clutch master and slave while your doing the brakes. I just did mine this last weekend and it took maybe half an hour to do brakes and clutch, I put in a new clutch master and slave before doing the fluid. Holy cow, I have never seen coffee colored fluid before....BAD previous owner...BAD.

I use a vacuum brake bleeder, pull about 4-8 oz. of fluid per bleed fitting (until it runs clear), top off the m/c between corners and that will flush things out, putting 1 qt. of new fluid in the system.

Should be done at least every two years. More often if you live in how humid areas because brake absorbs moisture. You can do it yourself with gravity one wheel at a time or all four and the LSPV. I have tubing that works on the bleeders so I do all four at one time (I do not have an LSPV). I buy a quart of fluid, get four containers and pour about one inch of fluid into the containers. Top off the MC. Set the container on the floor, push the tubing on to the bleeder nipple and stick into the containers. Start opening the bleeders in the same order you bleed the brakes DR, PR, PF, DF. Check the MC often and do not let it run dry. When the fluid starts running clear in the same order tighten up the bleeder. I then just pour the used fluid into the container that I put the used oil in for recycle. If you do this often, you will never have any problems with the system. What happens is the moisture settles to the bottom and corrodes and pits the MC, Calipers, and wheel cylinders. Takes about one-half hour to do it.

Another thing if you have a container of fluid that has been opened for more then a year you should recycle it. Do I do it as flush as often as I should, NO!!!!!!!! Do I throw out fluid that is over a year old, NO!!!!!!!!!! But I should!!!!!!!!

go to a farm supply place get a 120 cc syringe but some grease around the bleeder screw, get some small vacume tube and pull way.. fill the master every few pulls.

you can also, before you start pulling take the oil in the master and stir it up by pulling up then squirting the oil back down in there. you will be shocked.

I do it.

Tip. Use a turkey baster and suck the old fluid out of the reservour. Refill with fresh. Then flush. That way you're running new fluid through the cylinder and lines.

You beat me to it <img src="/forums/images/graemlins/kewl.gif" alt="" />

I had a master go bad, and the fluid was opaque, brown. I have only had my truck for 10K of 147K miles and it is obvious what happens if you dont change flush the stuff.

My rear passenger side would not flush, it was probably not working at all before changing it all out. The botton of teh resevoir was caked in black gunk. As I am towing a trailer tomorrow, I am glad to know it is all new fluid.

Yep, I do it too. Flushing the fluid is FAR cheaper and easier than fixing problems down the road. <img src="/forums/images/graemlins/mrt.gif" alt="" />

I use the vacuum bleeder to suck it dry first. If it's full of crud you can pour a little fluid in and swirl the hose around to suck up the rest before flushing. <img src="/forums/images/graemlins/cheers.gif" alt="" />
