Brake bleeding/ABS question
To change Brake fluid (I have a 1993 LT1 car), do you really have to bleed the ABS unit in the rear compartment?
Shop manual says you do to bleed the fluid, but only if you disconnected a line or let the fluid go down past the master.
Those who have changed fluid in the LT cars--what say you?

Unless you have had a problem with the ABS pump or gotten air into the lines, you should not have to bleed the ABS pump itself. In order to bleed the ABS unit, you have to have a Tech-1 with a brake module. That allows you to turn the pump on to get fluid through it.
For a simple fluid flush, just bleed the brakes in the sequencer as shown in the service manual.

There is some air in the system from what I feel in the pedal.
I ordered the motive so now I'll try that. But I don't want to mess with the ABS so if there's air in there-- I'll want to take it to the shop and make that his problem.
