Brakes do I bleed or anything? We replaced the master cylinder, and now we don't have any fluid coming out of the lines at all.
Do you
have the same problem?

Hi,

Was the new Master Cylinder bench bled prior to installing it? When bleeding the brakes, are you starting at the right rear, to the left rear, to the right front, and ending at the left front?

Do this. Make sure the Master Cylinder is full and remove the cap. Open the brake bleeder at the right rear wheel and allow it to remain open to see if it will gravity feed. If it does, close it, recheck the Master Cylinder fluid level, and do the same to the right rear, and so on.

If that works, then you can bleed the brakes with a helper.

As far as the bleeding procedures are concerned, read through step 3 in this link:

Here is a link that explains how to bleed the system once the new Master Cylinder is installed:

Let me know if this helps or if you have other questions.

Take care,

Joe

Okay, yes, we tried that, and it didn't work. But now what we did was pull off all the brake lines from the calipers and I think we got stuff messed up. So, is there anything you might be able to tell me like as if I was starting from having everything brand new and no fluid in it whatsoever and I think you should it has an ABS system as well.

Hi,

If you had the ABS apart, then it needs to be bled as well. This procedure requires a scan tool that can communicate with the antilock brake module.

If you look below, I attached the directions for the procedure.

Let me know if this helps or if you have other questions.

Take care,

Joe
