[JRKOUPE]

..Ive searched but was wondering where can I find a simple, correct diy step by step procedure for bleeding the brakes...its about time I stopped paying 60 bucks everytime I get it done, and thats like 2-3x per yr.....( car is tracked only and sits at times x months)..thanks!!!!

buy a pressure bleeder. they are about $50.. I got mine at bavauto. makes bleeding brakes very easy, no more pumping or messing around. since you bleed your brakes all the time it would definitely be worth it.

You can buy one (http://www.trackhaus.com/index.php?m...roducts_id=267 ) or you can make one yourself for 1/2 the cost:

hey nando.....nice to see a response from a regular that I know and respect. Are the instructions included.......I know it cant be hard but I want to have confidence I can bring the car down from track speeds safely and consistently........once I did my brakes pads I realized how ez it was.......Im sure this will turn out the same.


...wizarD...thanks for that site.....

Doc, if you are cheap like me, look on eBay for a Motive Products Power bleeder - they make the ones for BavAuto and BMP. Be sure you get the one with the EUro/BMW cap on it.

Its easy - fill it with fluid, attach to the brake reservoir, pump it up, then bleed.

Start with the pass. rear, then driver rear, then pass front then driver front.

it's pretty much self explanitory.

you fill the bleeder with fluid, and connect it to your resivior. You will need more than 1 liter because when it gets to the bottom it will depressurize. the rubber "gasket" that came with my bleeder was junk and leaked pressure, so I threw it out; instead I borrow the grommet from the resivior cap and put it on the bleeder. this seals it pretty well, and I put it back on the cap when I'm done.

then you pump up the bleeder to pressurize the system. 15-20psi is good, don't go much over 20 though - you'll pop the seals under the resivior and make a big mess on your garage floor.

then it's just a matter of opening up each line and letting the pressure do all the work. I'm sure you know to start with the line furthest from the resivior and working your way to the closest. you might have to pump up the bleeder a couple more times, but that's about it. you should be able to do the whole car in an hour - and you can use it to bleed your clutch too.

+1 on the BavAuto bleeder only pump it up to a good 15 - 18 rather than the DO NOT EXCEED 10PSI per the instructions.

start farthest away and move closer to the MC and dont forget the clutch. This is a perfect time to use the super gold/blue fluid so you know when the lines are fully flushed.

.......how often would u bleed clutch?....

One liter is more than enough for a full flush/bleed on a BMW. I start by sucking all of the fluid from the reservoir and refilling with fresh and then using a pressure bleeder I'll push 225cc (measured) through each rear wheel and 125cc through each front. Which leaves enough to have the level between the marks and is more than the lines and calipers can contain.
