The brakes need replacing now and at 60K LR recommends replacing the fluid. I am going to rebuild my front calipers as the seals are torn up, (no leaks though) my question is: 1. Am I going to face any serious problems due to ABS when draining the whole system? 2. Has anyone ever re-built DII calipers? Thanks for the help--Matt   J E Robison Service Co (Robisonservice) Member Username: Robisonservice Post Number: 60 Registered: 10-2002 Posted on Saturday, April 05, 2003 - 09:10 pm:    Avoid draining the system of fluid by clamping the brake hoses while the calipers are off. A drained system will probably be impossible for you to bleed. DII requires the Testbook for proper bleeding, using the pump to drive fluid through the ABS body. Otherwise you can't get the air out. I have my doubts as to how effectively you can change fluid in a DII at home because of this. More exactly, you can pump fluid through thereby getting fresh liquid into the system, but air trapped in the ABS body probably won't get removed. So if you have a soft pedal (big DII problem) it will probably stay that way.

Oh well, I want it done right--Matt   Ron Brown (Ron) Member Username: Ron Post Number: 215 Registered: 04-2001 Posted on Sunday, April 06, 2003 - 01:50 pm:    Why rebuild the calipers? If they are not leaking the seals can't be that bad. Just syphon off the brake fluid from the MC and do it again in a week. You can definately bleed a DII successfully without test book. If you clamped off the hoses it would probably work out ok.

The seals just looked pretty torn up when I replaced my pads, but as you said if they are not leaking then they cant be that bad. --Matt
