Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
You may have a problem with the master cylinder. Otherwise, did you use a scan tool to bleed the abs? Sometimes air can get trapped here and you need a scan tool to get the brakes bled.
The master cylinder is separate from the brake booster.
A booster problem would cause a hard pedal probably not a soft one, soft indicates air in the lines.
Sometimes the seal in the master cylinder will leak, the fluid will enter the vacuum booster drum, pull the vacuum hose off the booster, insert a zip tie into the hole in the booster, use zip tie like a dipstick and see if any brake fluid is in there indicating a leak.
That's good that there is no fluid in the booster.
