After replacing the clutch there is no pedal pressure

Replaced my clutch and throw out bearing, put the car back together and went to bleed the clutch. There is absolutely no pedal or pressure and it's internally leaking. Did I miss something or do I have to take the vehicle apart and get into the transaxle again? Was hoping for a leak in the line or a reason why it may be doing it?

Good afternoon,

Did you replace the clutch slave or the throw-out bearing?

I attached the bleeding process below for you to follow.

If it does not create a pedal, you may have a failed clutch master cylinder.


Hydraulic Clutch Bleeding

Notice: Do not reuse the fluid that has been bled from a system in order to fill the clutch master cylinder reservoir for the following reasons:

1. The fluid may be aerated
2. The fluid may be contaminated
3. The fluid may contain too much moisture

Important: Maintain the fluid level in the clutch reservoir to the top step with GM P/N 12345347, or equivalent.

1. Clean dirt and grease from the cap in order to ensure that no foreign substances enter the system.
2. Attach a hose to the bleeder screw on the clutch actuator assembly. Submerge the other end of the hose in a container of Hydraulic Clutch Fluid GM P/N 12345347, or equivalent.
3. Depress the clutch pedal slowly and hold.
4. Loosen the bleeder screw to purge air.
5. Tighten the bleeder screw to 2 Nm (18 inch lbs.).
6. Repeat steps 3 - 5 until air is purged.
7. Fill the reservoir to the top step with GM P/N 12345347, or equivalent.
8. Repeat the bleeding procedure if necessary.
