Flushed my brakes today. I used 3 (12oz) bottles for the job. I looked in my owner's manual and it did not have anything on the capacity for it. Anybody knows exactly how much is required to completely replaced the old fluid?

 

[grillmasterp]

the exact amount is 38.7 oz......J/K
No specified capacity- The only way to calculate would be to measure the length & inner diameter of ALL of the hoses and tubing and calculate the volume blah...blah...blah...

***Just flush until it comes out clean- be sure to flush at all 4 corners AND the LSPV.

Uh-oh, what is the LSPV. I did not do this for sure.

LSPV= Load Sensing Proportioning Valve
aka- BPV or Brake Proportioning Valve

Thats the module that is located on the left frame rail above the rear axle. It is connected to the rear axle with a metal bar that senses the axle position, and adjusts the braking power from front/rear depending on vehicle stance.
Look on the back of that module, and you will see the bleeder valve.

Thanks a lot! I guess I will be doing that tomorrow. I need to remember this next time ( 2 years from today)

I didn't bleed the LSPV either, didn't realize there was a fitting there. In what order would you bleed that fitting, after the rears and before the right front?

Thanks, Ken

I do the LSPV last

Another to remember is that when you are flushing the lines i like to go ahead and just empty the resevior as much as possible without getting air in the line then start adding the new good fluid. This way you get the clean stuff in there much faster.

just a personal preference on that one.

Yeah I do the same. I just get a free syringe from the pharmacy at Walgreens to suck out most of the old stuff.

Well that's a pretty slick way to do it. good thinking there.

So what do all those other syringes get used for????? hmmmmm???

I'm to lazy to bother to pick one up while i'm at work. So I just open the bleeder put the drain tube into bottle and pump the brake for a little while. works pretty quite well for me.

Those one man brake bleeder kits that you can get at pretty much any auto place for like 5-8 bucks or something like that. They are definately worth the money for those. They come with different size peices to fit into the bleeder valve.

This is what I used: http://www.apexperformance.net/cartgenie/prodInfo.asp?pid=46&cid=8
It works as advertised.

how often should you flush your brakes?

I do it every 60k miles, which I'm pretty sure is what the factory maintenance schedule recommends. Basically if your brake fluid looks more like iced tea then clear fluid, time for a flush.

 

[alex9021]

Every 2 years. The brake fluid tend to absorb water from the air. If you let it stay in your system for too long, the moisture will corrode your system.

This little thing is well worth the $50. i have used mine quite a bit, and it works like a champ every time.

Just don't forget to flush the container with new brake fluid before you used it. The residual brake fluid from the last time you used it are contaminated with moisture. You don't want it going into your brake system.

That's a pretty cool little gadget... I think I'll add that to my Christmas list! LOL!
