Xrs abs problem

is the abs light illuminates in the cluster?

When you removed it from the vehicle, did you disconnect it from the proportion valve or from the abs block?

Check each wheel to see if the hoses have air bubbles.

How does the brake pedal travel feel? Squishy or longer travel to stop? Check the master cylinder. The o ring may be leaking there.

Abs light is on
Removed all brake lines in the engine bay never disconnected from booster or abs module juss removed from calipers and pulled everything has been bled numerous times to no avail no air bubbles but when pedal reaches near bottom u can hear like an air leak around the booster long to stop no leak around the master just air noise that comes from the abs area no visible leak no wet lines but that air sound doesn’t stop every time pedal is pushed near the bottom air is heard

You won't see a leak around the master cylinder. The leak is on the inside at the piston.

You will have to retrace the steps you took. The problem is at the proportion valve on the firewall.
