Remove the old master cylinder. Use line wrenches to avoid damage to the brake line fittings. Bench bleed the the new master cylinder you have purchased. The parts store will tell you how to accomplish this and sell you the necessary bleed kit. Carefully install the new master cylinder. Reconnect the brake lines and do not over tighten. Now with a helper, bleed the brake system. Start at the Right Rear wheel. Find the bleeder located on the back side of the wheel at the wheel cylinder. It should have a small rubber cap. Remove the cap and using a boxed in wrench, loosen the bleeder valve slightly while your helper is applying steady pressure to the brake pedal. The pedal will go to the floor and you will see and hear air bubbles come for the bleeder. Tighten the valve and then tell the helper to release the brake pedal and do it all over again. Keep doing this until no air appears. Periodically check the master cylinder and do not allow the fluid level to get too low as it will suck more air into the system. Remind you helper to never release the brake pedal until you give the OK. If he releases the pedal while the valve is open, air will be drawn into the system. Now after bleeding the RR wheel, move to the LR, then RF, and finish with the LF.
