04 Hyundai Elantra one wheel locked up
Hello everyone, I have a 2004 Hyundai Elantra gls with abs brake system,
the car is in really good condition for its age, no rust under neath. The
problem is the right front passenger wheel was locked up when I went to
leave. I replaced the caliper and the flexible brake hose. I inspected all brake
lines going to abs and then to master cylinder, all good. All other wheels turn
freely. Here's the kicker, I take off the master cylinder cap and can press the
caliper on the drivers side easily and fluid returns to reservoir, when I try to
compress the caliper on the passenger side, it does not move, no fluid is
going back to the master cylinder. I can only release the cylinder with the
bleeder. I apply the brake again and drivers side spins, the passenger side is
locked up. What would cause the fluid not to go back to master cylinder?
Thanks
