Hyundai 58510-1R200 Cylinder Assembly-Brake Master

The installation process involves bench bleeding the master cylinder before installing it. Mount the master cylinder in a vise and attach a pair of master cylinder bleeder tubes to the outlet ports. Fill the reservoir with the recommended brake fluid and use a large Phillips screwdriver to slowly push the pistons into the master cylinder, expelling air from the pressure chamber into the reservoir. Repeat this procedure until no more air bubbles are present. Remove the bleed tubes and install plugs in the open ports to prevent fluid leakage and air from entering. Install the reservoir cap. Install the master cylinder over the studs on the power brake booster and tighten the attaching nuts finger tight. Thread the brake line fittings into the master cylinder, being careful not to strip the threads. Fully tighten the mounting nuts and brake line fittings. Fill the master cylinder reservoir with fluid and bleed the brake system.
