Hi guys,
OK I've searched, and come up empty.
I've downloaded the BMW Integral ABS Systems Flushing and Bleeding 101 - Great Document, but am looking for a couple of other articles it refers too.
Item 11 - Filling adaptor - See Article:
BMW Integral ABS System - (the above doc?)
Wheel Circuit Filling Adaptor - Looks like a funnel to me, am I wrong?
Item 13 - Wooden Dummy New Brake Pad Blocks - Anyone got measurements, or is it two new pads + thickness of disk, less a mill or two?
Thanks Guys
Mike
You can buy the funnel from Beemerboneyard and I bought the Speed bleeder bag from Racer Parts Wholesale. I wish one of htem sold both items, but last I checked they didn't. The shipping for the bag is more than the cost of the bag, but is sure was helpful. I didn't buy the speed bleeders themselves as I don't really see a need for them.
My wife pumps the brakes for me, but I could have done it myself if required. It is just easier with two people even with the bag.
As for the dummy blocks, I pushed the pistons in using an automotive caliper tool I already had. I then measured and just cut off a piece of 2x4 so that it was a snug fit. I think I endedup being about 7/8" thick. I didn't see a need to make two blocks for each caliper as one thick one worked fine and I hung the calipers with bent coat hangars so I didn't need to place them back over the rotors. Once I got the thickness correct, I had to cut maybe 1/2" off one end of the 2x4 pieces so it ended up being the nominal 1.5" by maybe 3" rather than the standard 3.5" nominal for a 2x4.
Most people recommend hardwood blocks, but I had only pine available. There is not that much pressure exerted on the blocks assuming you don't hold the brakes on hard with the bleed valve closed. And mine were cut so that the grain was perpendicur to the piston faces and even softwood is pretty strong when the force is aligned with the grain which is the case the way I cut my blocks. If you want a picture of mine, just drop me a PM with your email address. But mine are stupidly simple. I did find that the block that fit snugly in the rear caliper was a touch too thick for the front so I had to make the front ones slightly thinner than the rear.
