Hi Tim,
Yes you can bleed the system just as if didn't have ABS.
On the noise, it could be that the rods upon which the caliper slides are a bit corroded, but you would need to remove the calipers and polish them with some steel wool. Or it is possible that the anti-rattle clips are missing or worn out (but that would also cause a clatter when you are merely driving the car, so if you don't hear that then the anti-rattle clips are probably o.k. If you replaced the pads recently the noise may be due to the new location of the calipers with the thicker pads in place, but it may quiet down with use. On the noise from the steering column, that is not surprising because it takes the most torque to rotate the spindles when the car is at rest. It is better to not do that anyway, so just ignore it.
AnswerHi Tim,
Let me clarify the answer:
If you have not opened or replaced the pressure hose, the return hose or the pump/motor assembly then you don't have to bleed the booster part of the system. If you have opened or replaced those parts tell me and I will give you the instructions for bleeding than part.
If you have only changed the brake pads/shoes or the normal brake lines then the bleeding procedure is very much the same as if you didn't have ABS. If you don't have a pressure bleeder but rather are going to pump the system at the pedal then here is the way to do it:
Begin by depressurizing the hydraulic accumulator by pumping the brake pedal 25 times after you have turned off the ignition and disconnected the battery. You should feel a change in the brake pedal, requiring more force. Pump it a couple of more tiems after your feel that change in force.
Then do the normal bleed procedure (pump pedal fully a few times, wait 5 seconds, do it again, wait, etc.). Then full pressure on the pedal while a helper opens the bleed screw, pedal drops, close bleed screw, repeat, continue till no bubbles in brake fluid filled collector jar. Do left rear, right rear, left front, right front in that order.
So the basic answer is if you didn't mess with the motor/pump and its hoses, then you can treat the bleed pretty much like you don't have ABS except for depressurizing the accumulator (which isn't part on a non-ABS system).
If you did mess with the other parts, tell me and I'll give you the procedure for bleeding that part first.
