Q: How to remove and install the proportioning valve on Hyundai Accent?
A: For 1986-1999 models, use a flare nut wrench to unscrew the tube nuts at the Brake Lines' ends entering the Brake Proportioning Valve. Remove the lines, plug ends, remove the mounting nut, and remove the Brake Proportioning Valve. To install, position the Brake Proportioning Valve, insert brake lines, screw tube nuts by hand, install the mounting nut, and bleed the brake system. For 2000 and later models, unscrew brake lines and Brake Proportioning Valves from the master cylinder. Installation is the reverse of removal.
