We then put out a search for a new unit. We checked with all dealers, AC Delco and GM. I literally missed out on the last brake pressure modulator valve available in the country by 1 week. So now I need to find one from a junk yard.
My part # is 25705266. It has been superseded by #19416841, w/o traction or active brake control.
The available cross reference is for 2001-2 Aurora, 2000-5 Buick Lesabre and Park Ave, 2001 Cadillac Deville and 2000-5 Pontiac Bonneville.
To date I have purchased and had to return 4 units.
According to my mechanic, If there is any sign of corrosion or foreign material in the solenoid block, or the brake line ports are blocked at all, he does not feel safe installing it. Especially since it is a key component of the braking system.
Here are my questions:
Can the ABS Brake Pressure Modulator Valve and pump be rebuilt?
Can the modulator valve area be flushed out, so it would be safe to use?
Am I overlooking an avenue to find a new ABS unit?
have the same problem?
