Kia Troubleshooting Questions? Ask a Mechanic
Hi. Generally the abs hydraulic unit causes this concern. There are 2 lines from the master which then get split diagonally in the hcu. Verify you have fluid at the hcu from the master by cracking the lines. Then check the output lines of the hcu for brake fluid.
Hi. Thank you for viewing my response. Have you made any progress with checking the hydraulics?
