Replaced rear pads and shoes
you can try to bleed the brakes at all the calipers several times until the fluid is clean coming out the bleeder screws.it sounds like when you pushed the pistons back into the calipers you pushed dirt back through the system and has lodged in the abs hydraulic unit causing the light to come on.you say the abs light is still on does this mean it was on before you replaced the brakes.if so then you had a code in the abs controller that should have been checked before and repaired.when the abs sets code it automatically shuts down the traction control and all wheel drive because of the abs light being on.

2005 lincoln aviator on fifth battery in nine years. Why?
Motorcraft Batteries?
In my Lincoln L/S, the first one lasted 3 1/2 years & was done under warranty
Second one lasted 5 years
Now that one failed two weeks ago at 20 months
In my case the battery is in the trunk & you can't find a battery with
a vent for that car & ford batteries are on odd size, just for their
design or group size,go figure
The Motorcraft Max is free for 3 years & pro rated for 100 months,
so not a bad deal.
IF you have a big enough battery tray & a basic looking battery,
try the NAPA Legend Batt 8465 750 CCA 65 BCI (group size)
They are from East Penn MFG in Penn & plants in other states & their own brand is DEKA in the private parts stores
What I like is that there are no caps on top & no leaking, just like
the old AC Delco I used for 40 years & got 7 to 9 years out of them
I have had a Napa in my 30 year old blazer for two year so far
The question,well I think it is part battery & part the load the electronics puts on the batteries
When I open the trunk & have only the trunk light on & with a
new or old battery, I only get 12.3 volts
I get the same thing on my scan tool data when I turn off the car
& then put the key on,yet all data is good KOEO or Engine Running.
What is the correct fuel pressure at the rail for
Disconnect the electrical connection to relieve the system's pressure. Start the Navigator and let the engine run until it stalls from lack of gasoline. Turn off the ignition, reconnect the pump's electrical connection and disconnect the negative battery cable.
Step 2
Detach the fuel pressure sensor vacuum hose. Check for fuel in the line. If there is fuel present in the line, the fuel delivery problem is likely caused by a faulty fuel pump pressure regulator. If there is no fuel in the line, reattach the vacuum hose and continue with the fuel delivery diagnostic.
Step 3
Twist off the fuel pressure test port cap and secure a pressure gauge to the fuel pressure valve. Reconnect the negative battery cable and start the engine. The pressure gauge needs to read 45 psi when at wide open throttle. High pressure readings indicate a malfunctioning pressure regulator. Low pressure readings indicate a clogged fuel filter or a broken fuel pump.
Step 4
Cut the engine. Relieve system pressure and remove the negative battery cable again so you can safely remove the fuel filter to check for clogs.
Step 5
Loosen the filter fittings and unhook the fuel lines from the filter. Undo and remove the bracket on the fuel filter.
Step 6
Inspect the filter for clogs and replace it with a new one if necessary. If there are no clogs, the fuel delivery problem is probably a faulty fuel pump.
Clunking and whinning when locked in awd
check the cv joints for wear. check rear drive shaft for worn slip joint splines and "u" joint wear. When you lock in awd there is no centre diff to allow the variations between the wheels and so you are experiencing a torque build up between the front and rear diffs . This put stress on the entire drive chain so any looseness or worn parts will display noises. Remember that the awd lock should be only used on surfaces that allow the tyres to slip and relieve the stress ( dirt road---snow---mud--ice )
Running hot
Your engine fan is temp control, it will lock up when you are driving at a high speed, the clutch could be bad and also you have a electric coolant fan too..
