2nd Gen Non-Engine/Transmission Brake bleed procedure for 96 3500

[FreeBMW]

Can anyone post the bleed order for a 96 3500 with rear ABS.



Also the locations of any werid combantion blocks that get bleed.



Disk fronts & drum rears ABS only on rear.





I have a pressure type bleeder that replaces the lid on the master cyl.





Thanks

Bleed order

No problems. I use a brake bleeder originally made for a 1940 LaSalle. (No joke. ) I've updated it with a modern clamp-on master cylinder adapter that has rubber seals that jam into the master cylinder intakes at the base of the reservoir. I never exceed 10 PSIG. Considering the age and the original use of the unit, I wonder what the gauge measures!



I empty the fluid out of the reservoir with an irrigating syringe first. A turkey baster also works. Then I fill the reservoir about 1/2 full, for the setup I have.



Do the rear first. One side or the other will have a longer brake line. I think it's the right side. Whichever it is, bleed the long side first. It will seem like about an hour of subjective time before you get clear, bubble-free fluid. Then tighten that bleeder, and bleed the other side on the rear. It will go much faster.



Then you need to do basically the same thing on the front. Bleed the right side, then the left side, then you are done. Top of the fluid.



There are no quirks in the proportioning valve , as were common in early 1970's Delco systems. You do not need to loosen a bolt, and install tool J-666 (or whatever) to hold a plunder in. This is a much easier job than it was on my 1976 FSJ. It uses twice the fluid, though.



For what it's worth, I use Castrol LMA. It's rated DOT 3 and DOT 4, without being silicone based. And, it comes in quarts!
