ABS modulator without adaptive cruise
was working but now I cannot get equal pressure to each line

My vehicle is being worked on by a certified technician

Has all the major electronic tools - gravity and pressure abilities
to refill and bleed the brake system

The vehicle has only 12,000 miles and does not need any sensor or bearing issues cleaned or replaced. It appears to be an internal ABS fault in not delivering equal pressure to each of the 4 lines

Since this is the newest model XKR would anyone know of a reputible rebuilder instead of replacing this part ???

In this model the MODULE and ABS pump are one unit and this vehicle has traction control but not adpative cruise control.

Or any special TECH info on part number C 2 P 14581

Thanks
