ABS trouble ... F53 .....

So, after fixing the furnace ... putting in new o2 sensors (fixing stripped threads) ... fixing antifreeze leak .... I thought I was ready to go.

Took the RV out to get propane and gas ... no brakes!

Played a bit and found that brakes work great at 0-5 mph range ... and above 30 mph .... at 5 - 20 I have to use two feet to push down on the peddle .... I can feel the abs fighting me.

Scanned and got an error code C1184 (Excessive Isolation Valve Failure) ... Just for the fun of it, I tried replacing the sensor on the rear diff ....

Now I get a new code ... C1158 (Left front wheel speed sensor).

Bolt holding it in is rounded off and almost completely rusted away (I have never touched it) .... don't know what I am going to do to fix this one!

I am even more confused this morning ...

Trying to find the sensors ...

NAPA lists them (UP 530915) .... same for both sides ... but they don't look like mine .... large plastic blocks ...

Rock Auto list a left front only (NTK ... AB1436) ... looks correct ... but 1) when I check on a different site it says this is for a 2002 - 2003 F53 2) they don't list the right

HELP!

Thanks .... Mike
