Default Brake Caliper not getting fluid

1993 K5 4x4 blazer: I hit a pothole in the highway recently and both the Brake and Anti-Lock light came on instantly. When I applied the brakes, the blazer pulled dangerously hard to the left. The following week, I replaced both calipers, pads and brakes lines on the front and interestingly, when I bled the passenger caliper, there was no fluid ! I reset (turned-off) the brake and anti-lock lights by jump/grounding H&A pins on the ALDL. The first time I applied the brakes, the Brake and Anti-Lock lights came back on. Why is the passenger-side caliper not receiving fluid from the master cylinder ? Is there a problem within the ABS module ? Seems odd that hitting a pothole could damage the ABS module.

One other note ... when looking at the ABS module on the driver-side fender-well, I did notice a small pin pushed out on the bottom of the module. I pushed it back in to match the one next to it. Still, no fluid is getting to the front passenger caliper. Any suggestions ?

Default Code Retrieval

I retrieved a code "61" from the ABS system tonight:

Code 61 = Pump Motor Run Fault

What is the fix for a Code 61 ?

i cant really find much on it on identifix. mostly generic responses

1. Test the brake lines for a good ground, this is how the Electro-Hydraulic Control Unit (EHCU) is grounded.

2. If OK, replace the EHCU.

thats actually pretty weird if it grounds off themetal brake lines
